Autotrophs use the energy from the sun and water from my aunt's sprinklers to create their own food by the process of photosynthesis. They are producers in the food chain.

49.

Phloem is the living tissue that carries organic nutrients to the rest of the plant, where it is needed. In trees, the innermost layer of the bark is the phloem. They transport soluble organic materials made during photosynthesis.

48.

This onion skin is an example of epithelial tissue. Epethelial tissue is composed of cells that line the surfaces of structures throughout the body. It is separated from connective tissue by a basement membrane. The functions of these cells are protection and transcellular transport.

47.

These sliced lemons are examples of ethylene. Ethylene is the simplest alkene and is called an unsaturated hydrocarbon. It has a role in biology as a hormone. It is the most produced organic compound in the world.

46.

This is a plant in my front yard and is an example of tropism . A tropism indicates growth in response to an environmental stimulus. The stimulus in this situation is the new sprinkler system installed and sprays out a growth hormone too.

45.

This cheese is an example of lactic acid fermentation. Glucose, sucrose, and fructose are converted into cellular energy and the product, lactic acid. Cardiac muscle cells are highly soluble to lactate.

43 & 44.

These two flowers are examples of ATP. ATP transports chemical energy within cells for metabolism. It is an energy source produced during photosynthesis and cellular respiration.

42.

If you open up this flower, you will see the flower's endosperm. Endosperm is produced in the seeds of most flowering plants during fertilization. It provides nutrition in the form of starch. Orchids don't have endosperm in their seeds.

41.

This is a fish I dissected in my marine biology class. This fish is an example of an exotherm. It is poikilothermic because its internal temperature varies with that of the environmental temperature.

40.

This flower is an example of a meristem. A meristem is the tissue in all plants with undifferentiated cells. It is found in the plant where growth takes place. Cell division in meristems is required to provide new cells for expansion.

39.

This is an auxin producing flower. Auxins are plant hormones that have an important role in coordination of growth and behavioral processes.

38.

These sliced cucumbers are examples of eukaryotes. An eukaryote's cells contain complex structures enclosed within membranes. Eukaryotes have a presence of a nucleus.

37.

This tomato is made up of enzymes. Enzymes are biomolecules that catalyze chemical reactions. This is also a protein, as most enzymes are. Enzymes convert substrates into products.

36.

This muffins are examples of complex carbohydrates. They are polysaccharides, which are formed of repeating units joining together by glycosidic bonds. They are not amorphous and soluble in water.

35.

This plant is a part of the Kingdom Plantae. The study of plants (botany), has identified 350,000 species of plants. They include organisms such as trees, bushes, herbs, grasses, ferns, and green algae. Green plants, such as the one shown in the picture, obtain most of their energy by the process of photosynthesis.

34.

This is a blurry picture of one of my dogs, Princess. Princess is an example of an endotherm because it is warm-blooded. Her fur maintains thermal homeostasis and keeps her body at a constant level.

33.

This is an example of a frond I found at West Meadow Creek in Stonybrook. A frond is a large leaf with many divisions in it. It is most typically found in ferns, palms, or cycads.

32.

My skin is an example of epithelial tissue. Epethelial tissue is composed of cells that line the surfaces of structures throughout the body. It is separated from connective tissue by a basement membrane. The functions of these cells are protection and transcellular transport.

31.

This is an aerial view of the tree outside my window. Phloem is the living tissue that carries organic nutrients to the rest of the plant, where it is needed. In trees, the innermost layer of the bark is the phloem. They transport soluble organic materials made during photosynthesis.

30.

This tree trunk found in my backyard is an example of cambium. The vascular cambium is located in the vascular tissue in the trees. It is the source of the secondary xylem and secondary phloem.

29.

This is an example of lactic acid fermentation. Glucose, sucrose, and fructose are converted into cellular energy and the product, lactic acid. Cardiac muscle cells are highly soluble to lactate. That's why they always say milk does the body good!!

28.

This bread is an example of grain-based fermentation. Sugar is converted into alcohol using yeast or bacteria. The alcohol is baked out to make the bread.

27.

This flower, although hard to see, has pollen in the center. Pollen is a fine powder that consists of pollen grains, which produces the male sperm cells of plants. Each grain of pollen contains vegetative and generative cells.

26.

This is a picture of my little cousin's frogs. These frogs are examples of ectotherms because they are cold-blooded. They are dependent on environmental heat sources and have low metabolic rates.

25.

This is the cuticle of a plant found in my backyard. A cuticle is a tough but flexible outer-covering of any organism. The cuticle serves protection differs in structure and chemical composition. It is produced by the epidermal cells of leaves and the cuticle minimizes water loss.

24.

These are my father's two birds. They are examples of heterotrophs. They are consumers in the food chain because they cannot produce their own food. They eat nuts and seeds and break down complex organic compounds.

23.

Veins are examples of transport proteins. Transport proteins are proteins that moves ions and small molecules. They assist in the movement of diffusion or active transports.

22.

This is an example of an amniotic egg. This egg was hatched by a chicken and an amniotic egg is an egg produced by birds, mammals, or reptiles.

21.

This is a rhizome, which is a horizontal stem of a plant that is found underground. The rhizome is used by farmers and gardeners to propagate the plants in vegetative reproduction. Ginger, asparagus, and Carras are propagated this way.

20.

This is a blurry picture of a worm with a segmented body. Each segment bears the same structure so organs are equally divided between all the segments so it's not as dangerous if one segment gets hurt.

19.

This is my cousin Julia showing off her skeletal muscles. Regulatory proteins are proteins that regulate the contraction of muscles by controlling the interaction of myosin and actin. Calcium is the most important component of the reaction.

18.

There are six different kingdoms in biological classifications: plantae, protista, animalia, fungi, eubacteria, and archaebacteria. My cousin Julia is in the animal kingdom, along with many other mammals. The animal kingdom consists of multicellular and eukaryotic organisms.

17.

This is a picture of me and my cousin Johnny. His nose and ears are made up of a connective tissue called cartilage. Cartilage makes up the entire skeleton and provides support but is not as flexible as muscle and not as hard as bone. Cartilage also takes more time to grow and repair.

16.

This is a picture of my nail and is an example of structural proteins. This structural protein is called keratin and is found in hard or filamentous structures like nails, hooves, or animal shells.

15.

This is a plant in my backyard and is an example of a plant hormone called gibberellins. This hormone increases the developmental process of germination.

14.

This grass found in my aunt's backyard is an example of an autotroph. Autotrophs use the energy from the sun and water from my aunt's sprinklers to create their own food by the process of photosynthesis. They are producers in the food chain.

13.

This is a picture of my Begonia plant in my backyard. It is an example of a long-day plant meaning that in order for the plant to thrive, it should have sunlight for more than 6 hours a day.

12.

This small tree found in my aunt's backyard has bilateral symmetry. Bilateral symmetry means you can cut the tree vertically and each side will be the same as each other.

11.

This is a picture of a horseshoe crab found at West Meadow Beach. They are found swimming in the ocean and in most saltwater marshes but their adaptation is that they have legs that they can walk up onto the sand for mating season. They need to mate in the sand so the females can keep their eggs in the sand and protect it from predators.

10.

This is a picture of a razor clam found in a creek for my marine biology class. It has a fascinating analogous structure. Most mammals have "legs" used to move around and support itself. The razor clam uses its one leg (the long thing sticking out of the middle) to dig into the sand to a safe depth.

9.

This is a picture of my stingray in a fish tank in my room. Stingrays reproduce sexually by the male going on top of the female and placing one of their two claspers into her vent. They are ovoviviparous meaning 5 to 10 live babies are born.

8.

I took this picture of a slug from the side of my house. A slug is an ectotherm because it regulates its body temperature by external means. They are dependent on heat sources and have low metabolic rates.

7.

These are two asian shore crabs that I found at West Meadow Beach and used them for a science experiment. There are both heterotrophs and eat dead, decaying matter and small fish. They are fighting because there is a fish in the bowl with them and it caused competition between the two crabs.

6.

This is a picture of my eye. Brown eyes are a dominant trait in my family. My mother, father, sister, brother, and me all have brown eyes.

5. Rice is an example of a C3 plant. C3 plants thrive in areas where sunlight is average, temperatures are average, and ground water is plentiful. They represent about 95% of Earth's plant biomass.

4.

Xylem is one of the two types of transport tissue. Its function is to transport water from the roots to the rest of the plant. It's also used to replace water that is lost during transpiration and photosynthesis.

3.

This is a picture of a seahorse I caught in the Long Island Sound for my marine biology class. The seahorse's exoskeleton supports and protects the body. A common misconception about seahorse exoskeletons is that it looks boney and rough but even the smallest anemone can sting and wound it.

2.

This is a picture of me in my room. My body undergoes endothermic processes to regulate a temperature of 98.6 degrees. The ability to cool my body down or produce body heat maintains thermal homeostasis.

1. This is an example of a flower ovary. A flower ovary is the female reproductive organ of the plant that holds the ovules and is located at the base of the petals. Ovules are premature seeds and the ovary ripens it into fruit after fertilization.
