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 are made of tissues, tissues are made of cells, and systems are made of organs — so the most basic unit is the
cell.

2. Which part of the cell is like the “brain” of the cell?
Answer: C. nucleus
Explanation:
The
nucleus contains the genetic material (DNA) and controls the activities of the cell, such as growth, reproduction, and protein synthesis. Because it directs the cell’s functions, it is often referred to as the "brain" of the cell.

3. Which of the following is NOT a function of the vacuole?
Answer: D. provides energy
Explanation:
The
vacuole in plant and animal cells serves several purposes:
- Stores water (A)
- Holds food (B)
- Stores waste (C)
However,
providing energy is not a function of the vacuole. That role belongs to the
mitochondria, which produce energy through cellular respiration.

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.
Answer:
1.
Nucleus
2.
Cytoplasm
(Other correct answers could include:
Mitochondria,
Cell membrane)
Explanation:
Looking at the diagram:
- Both plant and animal cells have:
-
Nucleus – contains DNA
-
Cytoplasm – gel-like substance where organelles are suspended
-
Mitochondria – produce energy
-
Cell membrane – controls what enters and exits the cell
But since the question asks for
two structures other than the central vacuole, you can choose any two from the list above. Common correct answers are:
- Nucleus
- Cytoplasm
(Note: Plant cells also have a
cell wall and
chloroplasts, but these are
not found in animal cells.)

✔ Final Answers:
1.
A. cells
2.
C. nucleus
3.
D. provides energy
4. a.
Nucleus and
Cytoplasm (or Mitochondria and Cell membrane — any two shared structures)
