1. what is the main function of a vacuole in a cell?

(1) storage
(2) coordination
(3) synthesis of molecules
(4) release of energy

1. which structure shown in the diagram below digests worn out cell organelles?

diagram of a cell with labels 1,2,3,4
(1) 1 (3) 3
(2) 2 (4) 4

1. which cell structure in the above diagram is the site for protein synthesis?

(1) 1 (3) 3
(2) 2 (4) 4

1. which cell structure in the above diagram is the site of cellular respiration?

(1) 1 (3) 3
(2) 2 (4) 4

1. an organelle that produces and releases atp energy for metabolic activity in a nerve cell is the?

(1) chloroplast (3) mitochondrion
(2) ribosome (4) vacuole

1. metabolic poisons work by inhibiting atp (energy) production. which type of transport would be most affected?

(1) osmosis
(2) facilitated diffusion
(3) active transport
(4) simple diffusion

1. what is common to all cells?

(1) all cells have a cell wall.
(2) all cells are photosynthetic.
(3) all cells have a nucleus.
(4) all cells come from preexisting cells

Explanation:

1. Vacuoles primarily store substances like water, nutrients, and waste in cells.
2. Structure 3 is a lysosome, which digests worn-out organelles.
3. Structure 1 is a ribosome, the site of protein synthesis.
4. Structure 4 is a mitochondrion, where cellular respiration occurs.
5. Mitochondria produce ATP, the energy currency for cell activities, including nerve cells.
6. Active transport requires ATP to move substances against their concentration gradient, so it is most affected by ATP inhibition.
7. The cell theory states all cells arise from preexisting cells; not all cells have walls, are photosynthetic, or have a nucleus.

Answer:

1. (1) Storage
2. (3) 3
3. (1) 1
4. (4) 4
5. (3) Mitochondrion
6. (3) active transport
7. (4) All cells come from preexisting cells
