h. All animal cells have several characteristics in common. Which of the following
statements applies to animal cells only?
1. the cell membrane is the outermost layer which contains the cell
2. nucleus controls all chemical reactions of cell
3. mitochondria produces and stores energy
4. cytoplasm is a jelly like fluid where all chemical reactions occur​

Answer 1

1. membrane in Biology the thin layer that form the outer boundary of a living cell or of an internal cell compartment or the outer boundary is the plasma membrane and the compartments in closed by internal membranes are called organelles
2. proteins made for export from the cell function as in that participate in all the body's chemical reactions or therefore the nucleus which contains the instructions for the synthesis of protein direct all cellular activities and does all body processes
3. Mitochondria are membrane bound cell organelles that generate most of the chemical energy needed to power the cells biochemical reactions on chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
