Here is the solution to the worksheet, with explanations for each question:
---
1. Which is the most basic unit of all living things?
✔ Correct Answer: A. cells
Explanation:
All living organisms are composed of one or more cells. Cells are the smallest structural and functional units of life. Organisms are made up of cells, tissues are groups of similar cells, and systems are groups of organs — so cells are the most fundamental level.
---
2. Which part of the cell is like the “brain” of the cell?
✔ Correct Answer: C. nucleus
Explanation:
The nucleus contains the cell’s genetic material (DNA) and controls all cellular activities — such as growth, metabolism, and reproduction — just like a brain controls the body. It directs what proteins are made and when, making it the control center.
---
3. Which of the following is NOT a function of the vacuole?
✔ Correct Answer: D. provides energy
Explanation:
Vacuoles in plant cells (and some animal cells) store water, nutrients, and waste materials. They help maintain turgor pressure (in plants) and can hold food or broken-down substances. However,
they do not provide energy — that’s the job of mitochondria (which convert glucose into ATP).
---
4a. Other than the central vacuole, name TWO (2) structures that are found in both the animal and plant cells.
✔ Correct Answers (any two from this list):
-
Nucleus
-
Cytoplasm
-
Cell membrane
-
Mitochondria
Explanation:
Looking at the diagram:
- Both plant and animal cells have a
nucleus (controls cell),
cytoplasm (jelly-like substance where organelles float),
cell membrane (controls what enters/leaves), and
mitochondria (produces energy).
- The
central vacuole,
cell wall, and
chloroplasts are unique to plant cells.
So you could write:
Nucleus and
Mitochondria
*(or any other two from the list above)*
---
✔ Final Answers Summary:
1.
A. cells
2.
C. nucleus
3.
D. provides energy
4a.
Nucleus and
Mitochondria *(or Cytoplasm and Cell membrane — any two shared structures)*
