Let's solve each question step by step and explain the answers clearly.

1. Which is the most basic unit of all living things?
Answer: A. cells
Explanation:
The cell is the smallest structural and functional unit of life. All living organisms are made up of one or more cells. Organisms, systems, and tissues are made *from* cells, so they are not the most basic unit.
✔ Correct answer: A. cells
---
2. Which part of the cell is like the “brain” of the cell?
Answer: C. nucleus
Explanation:
The nucleus contains the cell’s DNA and controls all cellular activities such as growth, reproduction, and protein synthesis. Just like the brain controls the body, the nucleus controls the cell.
✔ Correct answer: C. nucleus

3. Which of the following is NOT a function of the vacuole?
Answer: D. provides energy
Explanation:
Vacuoles store water, nutrients, waste products, and help maintain turgor pressure in plant cells. However,
they do not provide energy. Energy production occurs in the mitochondria (in both plant and animal cells) and chloroplasts (in plant cells).
✔ Correct answer: D. provides energy

4. The diagram shows the parts of the plant and animal cells.
a. Other than the central vacuole, name TWO (2) structures that were found in both the animal and plant cells.
From the diagram:
- Both cells have:
-
Nucleus
-
Cytoplasm
-
Cell membrane
-
Mitochondria
You can choose
any two from these common structures.
✔ Example answers:
- Nucleus
- Mitochondria
Or:
- Cell membrane
- Cytoplasm
(Any two of these four will be correct.)

✔ Final Answers:
1.
A. cells
2.
C. nucleus
3.
D. provides energy
4. a.
Nucleus and
Mitochondria (or any two of: nucleus, cytoplasm, cell membrane, mitochondria)
