Question

write t or f.

1. ____ atp stores energy in chemical bonds.
2. ____ chloroplasts are found in animal cells.
3. ____ all cells are surrounded by a cell membrane.
4. ____ homeostasis occurs in both unicellular and multicellular organisms.
5. ____ osmosis is the diffusion of water across a selectively permeable membrane.

Explanation:

1. ATP (adenosine triphosphate) stores energy in the high - energy phosphate bonds. So this statement is True (T).
2. Chloroplasts are the organelles responsible for photosynthesis and are found in plant cells and some algae, not in animal cells. So this statement is False (F).
3. The cell membrane (plasma membrane) is a fundamental structure that surrounds all cells, whether prokaryotic or eukaryotic. So this statement is True (T).
4. Homeostasis is the process of maintaining a stable internal environment. Both unicellular (like bacteria) and multicellular (like humans) organisms need to maintain homeostasis to survive. So this statement is True (T).
5. By definition, osmosis is the diffusion of water molecules across a selectively permeable membrane from an area of higher water concentration to an area of lower water concentration. So this statement is True (T).

Answer:

1. T
2. F
3. T
4. T
5. T
