Plants and their parts interactive worksheet - Free Printable

Task: Review Unit 1 - Looking after plants

#### Part 1: Drag and drop the parts of the plant
The image shows a plant with labeled parts. The task is to match the labels "STEM," "LEAVES," "ROOTS," and "FLOWER" to their respective parts in the diagram.

- FLOWER: The pink structure at the top of the plant.
- LEAVES: The green structures attached to the stem.
- STEM: The vertical structure connecting the leaves and flower to the roots.
- ROOTS: The structures underground that anchor the plant and absorb water and minerals.

#### Part 2: Answer the questions based on the picture
The second part of the worksheet asks questions about plant functions and photosynthesis. Here are the answers:

1. What is the function of the roots?
- Answer: Absorb water and minerals from soil.

2. What is the function of the stem?
- Answer: Transports water to the leaves.

3. What do plants need to make food?
- Answer: Water, minerals, carbon dioxide, sunlight.

4. What is the part of the plant that uses light to make food?
- Answer: Leaves.

5. What is absorbed from the air into the leaves?
- Answer: Carbon dioxide.

6. What is released from the leaves into the air?
- Answer: Oxygen.

Explanation of the Solutions

#### Part 1: Plant Parts
- FLOWER: The flower is the reproductive part of the plant. It produces seeds and is often colorful to attract pollinators.
- LEAVES: Leaves are responsible for photosynthesis, the process by which plants convert light energy into chemical energy (glucose).
- STEM: The stem supports the plant and acts as a conduit for transporting water, nutrients, and sugars throughout the plant.
- ROOTS: Roots anchor the plant in the soil and absorb water and essential minerals needed for growth.

#### Part 2: Photosynthesis and Plant Functions
1. Roots: Roots have tiny hair-like structures called root hairs that increase the surface area for absorbing water and minerals from the soil. These nutrients are then transported to other parts of the plant.
2. Stem: The stem transports water and nutrients absorbed by the roots up to the leaves and distributes sugars produced during photosynthesis to other parts of the plant.
3. Photosynthesis Requirements: Photosynthesis requires four main components:
- Water: Absorbed from the soil by the roots.
- Minerals: Also absorbed from the soil by the roots.
- Carbon dioxide: Absorbed from the air through small openings in the leaves called stomata.
- Sunlight: Captured by chlorophyll in the leaves to provide the energy needed for photosynthesis.
4. Leaves: Leaves contain chlorophyll, which captures sunlight and converts it into chemical energy (glucose). This is the primary site of photosynthesis.
5. Absorption from Air: During photosynthesis, plants absorb carbon dioxide from the air. This gas is used along with water to produce glucose and oxygen.
6. Release into Air: As a byproduct of photosynthesis, plants release oxygen into the air through the stomata in their leaves.
