Photosynthesis & Cell Respiration

By Allie Valenzuela and Emily Heffernan

Essential Terminology

Photosynthesis- the occurrences when a green plant converts light energy into chemical energy and stores it in the bonds of sugar


Cellular Respiration- the process in which cells convert food into usable energy in the form of ATP


ATP (adenosine triphosphate)- a nucleotide with two extra energy-storing phosphate groups

Plant: Rose

The structure of a rose has the roots called the anchor roots. The anchor roots carry water and nutrients up the plant for food. There is also shank which is part of the root stock and comes from the bud onion. The shank provides structure above ground. Next is the bud onion which is formed at the top of the shank and the canes grow from the bud onion. The canes grow from the bud onion and they are what form the leaves and roses. Bud eyes are where the canes extend down to the leaves and help produce new canes.

Chloroplast occurs in a rose because a rose is a plant. The green pigment, called chloroplast, uses CO2 and sunlight to make oxygen and sugars, which is food for the plant. The leaves take in the sunlight and the stomata on the leave takes it in. The leaves are sharp and usually are in a jagged form.

The stem helps hold the plant up but its main function is that the roots connect to it and send nutrients up through the stem. The stem in a way can be considered the main way of transportation in a rose everything flows through the stem and also supports the leaves and rose. The outer exterior of the stem has thorns on it to protect it from any other animal trying to break the stem.

The mitochondria is the powerhouse of the cell. 2 internal membrane bound spaces. Without the mitochondria in the rose there would be no power for the cell and many systems inside the rose would fail.

There is no blood stream in the rose.

The actual rose flower usually has 5 petals and can be in a variety of colors most commonly red pink or yellow.

The small intestine is covered by millions of villi which have 4 layers and extend about 1 mm into the lumen. molecules of glucose, chloroplasts, amino acids, cross the epithelium that the small intestine villi covers the and into the roses bloodstream. Villi can also absorb nutrients in the plant.

Animal: White-Tailed Deer

Every cell in an animal requires oxygen to perform cellular respiration, which gives off carbon dioxide and water as waste products.

The white-tailed deer is a herbivore. Herbivores are animals that get their energy from consuming plants. The plants take in carbon dioxide from the deer, and in turn, the deer take in oxygen and sugars (glucose), from the plant, as a never-ending cycle.

The deer, being an animal, has no chloroplast, roots, stems, leaves, or mitochondria, unlike a plant. They do have lungs, a blood stream, and small intestines, which all play a part in cellular respiration.

The lungs are the special organs in the body composed of small chambers filled with blood capillaries. After air enters the lungs, oxygen diffuses into the blood stream through the capillary walls. It then pumps the oxygen to the rest of the body's organs and muscles.

The blood stream is the thing in which the oxygen diffuses into. Without the bloodstream, nothing would reach anywhere from one part of the body to another, which is essential for cellular respiration.

The small intestines in the white-tailed deer are small tubes in the digestive system where food is absorbed into the blood. This assists with cellular respiration by transporting the food into
