1. Living Organisms-Plants Lesson 3

2. Are plants living or non living?
Plants are living (biotic) things.

3. What is the big difference between plants and animals?
The one big difference between plants and animals is plants can make their own food.

4. What is the name of the process that allows plants to make its own food?
A plant makes its own food by a process called photosynthesis which takes place in the plants leaves.

5. The process of photosynthesis
The process of photosynthesis: Light is trapped in the chlorophyll, the material that makes a leaf green. The light energy starts the food making process. The plant uses carbon dioxide and water to make the food. The leaves take in carbon dioxide and the roots take in the water. The water travels to the leaves. The leaves use the energy from the light to make food from the carbon dioxide and water. The food made is sugar. Oxygen is a waste product of photosynthesis. It is given off by leaves.

6. What are the three components that allow photosynthesis to take place?
A plant needs light, carbon dioxide, chlorophyll, and water to carry out photosynthesis.

7. What are the three basic plant parts?
There are three basic plant parts : leaves, stems, and roots

8. Are all leaves the same?
Leaves come in different shapes and sizes.

9. What is a leaf’s job?
Leaves help carry out the process of photosynthesis.

10. What is a stem’s job?
Stems support plants and give them shape. They also contain tubes that carry water and minerals from the roots and food from the leaves to all parts of the plant. Stems also store water and food.

11. What is a root’s job?
Roots: There are many different types of roots, however most roots are underground and hold plants in the soil. Roots take in water and nutrients that plants need for photosynthesis.
Ex: Cacti have roots that grow near the surface because it is easier to collect rain water in their very dry climate.

12. What does a plant need from its environment in order to survive?
To live, a plant needs four things from its environment-air, nutrients, water, and light.

13. What is breathed out by animals and taken in by plants?
Carbon Dioxide is a gas breathed out by animals and taken in by plants.

14. Where do plants get nutrients?
Plants get nutrients from soil and water from rain.
