Animal and Plant Cells Worksheet: Identify and label cell structures and match functions.

Let's solve the worksheet step by step.

1. Identify and Label the Cells

We are given two diagrams:

#### Left Diagram:
- It has a round shape.
- It has a cell membrane, nucleus, mitochondria, and cytoplasm.
- It does not have a cell wall or chloroplasts.
- This is typical of an animal cell.

✔ So, label it:
This is an animal cell.

Now, label the parts:
- The outer boundary → Cell membrane
- The large central structure with DNA → Nucleus
- The small oval structures (often green or red) → Mitochondria
- The jelly-like substance filling the cell → Cytoplasm
- The tiny dots or granules → possibly ribosomes, but not listed; so focus on listed ones.

#### Right Diagram:
- It has a rigid, rectangular shape.
- It has a cell wall (outer green layer).
- It has chloroplasts (green oval structures).
- It has a large central vacuole (not listed in the word bank, but present).
- Also contains nucleus, mitochondria, cytoplasm, and cell membrane.

✔ So, label it:
This is a plant cell.

Label the parts:
- Outer rigid layer → Cell wall
- Green structures → Chloroplasts
- Inner boundary → Cell membrane
- Central large structure → Nucleus
- Jelly-like fluid → Cytoplasm
- Small oval organelles → Mitochondria

2. Match Cell Parts to Their Functions

We are given these parts:
- NUCLEUS
- MITOCHONDRIA
- CHLOROPLAST
- CELL MEMBRANE
- CELL WALL
- CYTOPLASM

Now match them to the functions:

#### a) "This is responsible for controlling what goes in and out of the cell."
- ✔ CELL MEMBRANE – It regulates the movement of substances in and out of the cell.

#### b) "It’s where most of reaction take place. It’s also responsible for giving the cell its shape."
- ✔ CYTOPLASM – It is the site of many cellular reactions and helps maintain the cell's shape.

> Note: In plant cells, the cell wall gives rigidity, but the cytoplasm supports internal structure and reactions.

#### c) "This part holds all of the DNA."
- ✔ NUCLEUS – It contains the genetic material (DNA).

#### 1. Fill in the blanks and label:

Left diagram:
This is an animal cell.
Label:
- Outer edge → Cell membrane
- Large center → Nucleus
- Oval green/red dots → Mitochondria
- Fluid inside → Cytoplasm

Right diagram:
This is a plant cell.
Label:
- Outer green layer → Cell wall
- Green oval structures → Chloroplasts
- Inner boundary → Cell membrane
- Large central structure → Nucleus
- Fluid → Cytoplasm
- Small oval structures → Mitochondria

#### 2. Match the functions:

- CELL MEMBRANE – This is responsible for controlling what goes in and out of the cell.
- CYTOPLASM – It’s where most of reaction take place. It’s also responsible for giving the cell its shape.
- NUCLEUS – This part holds all of the DNA.

📌 Summary:

- Animal cells: No cell wall, no chloroplasts, flexible shape.
- Plant cells: Have cell wall, chloroplasts, rigid shape.
- Key organelle functions:
- Nucleus = DNA storage
- Cell membrane = control of movement
- Cytoplasm = site of reactions & shape support
- Chloroplasts = photosynthesis (only in plants)
- Mitochondria = energy production (in both)
