1.) In the structure of a eukaryotic plant cell consist of a membrane-closed nuclei and organelles, since they developed a process in which they manufacture their own food. The Chlorophyll, which gives the plant the green color captures sunlight to convert water and carbon dioxide into glucose and carbs, in which are used for the repetition of the cycle. Not only does the plant cell consist of a membrane, unlike other eukaryotic cells it additionally has a cell wall in since it has a much bigger central vacuole. They also have plasmodesmata, and chloroplast only found in plant cells. A nonphotosynthetic prokaryotic cell would differ from a generalized eukaryotic plant cell by the presence of a nucleus and the structures of the cell. Plants do not have bones structural strength besides the membrane, also the vacuoles contain nutrients and liquids and the chloroplasts contain the organelles that help the plant to get energy form the sunlight. A prokaryotic cell usually gets its energy from sugars and other organic substances and they have a cytoskeleton like cilia.

2.) In the cell all of the activities and functions are going to require energy in order for it to have these reactions. ATP and ADP play a big role in the cell’s organelles since without them they would not have the energy reaction to be able to function.

A) Most cells generate themselves with cilia or flagellum, these structures are powered by structural changes that happen when ATP is burned.

B) ATP is required to active pumps and channels to push nutrients against their concentration gradient (moving them from where there is less to where there is more concentration, particles do not like to do this)

C) Your body using enzymes to control rates of synthesis, refer to A and B for how.

D) Same answer as B.

E) ATP is used to burn glucose into 2 pyruvic acids.

3.) Osmosis- is diffusion but with water. Diffusion is the movement of...
