Glycogen




This kind of scary looking tortoise and rabbit are eating grass that will soon become glycogen. Glycogen is a polysaccharide (carbohydrate) that is stored in the liver and muscles of animals. When the time arrives, this glycogen will get converted to glucose. Glucose can also be found in protein filled animal products.

ATP



ATP is the "energy currency" of cells. Basically, ATP is an energy source for important functions inside the cell. For example, in the post below, ATP was vital for the calvin cycle. The photo above is of a flower, a flower that is going through the calvin cycle and therefore using ATP. ATP is used as an energy source. ATP is used in both animals and plants.

Calvin Cycle



The calvin cycle is when carbon dioxide is added to "RuBP" to form a two 3 carbon molecule called 3-phosphoglycerate. By using ATP and NADPH (now ADP and NADP+), 3phosphoglycerate forms into glyceraldehyde-3-phosphate (glucose). To make the story short, the calvin cycle is one part of the photosynthesis cycle. The photo above is a picture of a plant that is in the sunlight. By using the sunlight stimulation and the carbon dioxide around, the plant is continually going through the calvin cycle. Any plant is an example of the product of the Calvin Cycle.

Phloem



Phloem is a part of the plant that transports sugar (sap) to all parts of the tree. The photo above shows a part of a plant, the bark. Beneath the bark is phloem (next is the cambium and xylem). Examples of phleom are everywhere in a rainforest or a jungle.

Lipid Uses for Energy Storage



Lipids are organic molecules that are insoluble in water and consist of what we know as "fat". The photo above is olive oil, a key example of a lipid. Since lipids are not soluble in water, this is why olive oil dressing has separations within the liquid. Cream, grease, animal oil are all lipids.

Mollusks



Mollusks are a phylum that contain a wide variety of organisms. The photo above is of snails, a gastropod. Gastropods are the most diverse section within the phylum of mollusks. Snails are invertebrate and have shells, a typical characteristic of mollusks. Clams and oysters are also mollusks.

Thorn of a Plant



In the photo above, the sharp purple section of the plant is the thorn of the plant. This thorn protects the plant from herbivores. Thorns are modified stems of this plant, as shown above.
