Educational worksheet for students to match cell organelles with their functions and identify parts of a plant cell diagram.

Let's solve this worksheet step by step.

Part 1: Match the Organelle to Its Characteristic/Function

We are given a list of functions and need to match them with the correct organelles from the list:

Organelles:
a. lysosome
b. cell wall
c. cell membrane
d. nucleus
e. cytoplasm
f. vacuole
g. mitochondria
h. chloroplast

Now, let’s go through each function and match it correctly:

1. Contains the DNA of the cell → d. nucleus
- The nucleus houses the genetic material (DNA).

2. Breaks down wastes → a. lysosome
- Lysosomes contain enzymes that digest waste materials and cellular debris.

3. Creates energy by cellular respiration → g. mitochondria
- Mitochondria are known as the "powerhouse" of the cell because they produce ATP via cellular respiration.

4. Allows materials to go in and out of the cell → c. cell membrane
- The cell membrane regulates the movement of substances in and out of the cell.

5. Rigid, outer layer for protection of plant cells → b. cell wall
- Plant cells have a rigid cell wall made of cellulose for structural support.

6. Stores water and other materials for the cell; larger in plants than animal cells → f. vacuole
- The central vacuole in plant cells stores water, ions, and waste products and helps maintain turgor pressure.

7. Contains chlorophyll and is where photosynthesis takes place → h. chloroplast
- Chloroplasts are found in plant cells and conduct photosynthesis using chlorophyll.

8. Jelly-like fluid that holds all organelles in their place → e. cytoplasm
- The cytoplasm is the gel-like substance inside the cell where organelles are suspended.

Part 2: Use the Image to Answer the Prompts

Look at the diagram:

- A: Outermost structure → likely the cell wall
- B: Small structures scattered throughout → possibly chloroplasts or mitochondria, but since it's a plant cell (we'll confirm), these could be chloroplasts.
- C: Dark circle → nucleus
- D: Large central structure → vacuole

Now, answer the questions:

#### 1. Which type of cell is pictured, plant or animal?

✔ Plant cell
- Reason: It has a cell wall (A), a large central vacuole (D), and chloroplasts (B). These are features unique to plant cells.

#### 2. Based on the passage, which organelle is labeled as “A”?

✔ Cell wall
- A is the rigid outer layer, which matches the description of the cell wall (organelle b).

#### 3. Based on the passage, which organelle is labeled as “B”?

✔ Chloroplast
- B appears as small green dots (in typical diagrams) and are involved in photosynthesis. From the passage, chloroplast (h) contains chlorophyll and is where photosynthesis occurs.

#### 4. Organelle “C” is known as the control center because it houses DNA for the cell. Which organelle is labeled “C”?

✔ Nucleus
- C is the dark round structure in the center — this is the nucleus (d), which contains DNA.

#### 5. Organelle “D” is filled with water and other fluid and is much larger in this plant cell than it would be in an animal cell. Which organelle is labeled “D”?

✔ Vacuole
- D is the large central sac-like structure. This is the vacuole (f), which stores water and maintains cell shape.

6. f
7. h
8. e

#### Image-Based Questions:
1. Plant cell
2. Cell wall
3. Chloroplast
4. Nucleus
5. Vacuole

This worksheet teaches the key organelles and their roles, especially distinguishing between plant and animal cells. The presence of a cell wall, large vacuole, and chloroplasts confirms it's a plant cell.
