Plants Review Packet Test: Friday, January 13 th Review: Textbook Pages: 48 -65; 68 -73; 172 -177 Plant Adaptation Packet Vocabulary Cards

1. What are the four things plants need to survive? (p. 54 -55) The four things plants need to survive are light, carbon dioxide, water, and nutrients.

2. What are the main parts of a plant? (p. 52 -55) The main parts of a plant are roots, stems, leaves, and flowers/fruits.

3. Why are roots important? (p. 53) Roots are important because they take up water and nutrients from the soil, and keep the plant firmly in the ground.

4. Why are stems important? (p. 53) Stems are important because they move food, water, and nutrients through the plant and they keep the plant from falling over.

5. Why are leaves important? (p. 54 -55) Leaves are important because they make food (sugar) for the plant by going through the process of photosynthesis. They take in sunlight and carbon dioxide and let out oxygen.

6. Why are flowers/fruits important? Flowers/fruits are important because they produce and protect seeds.

7. Describe the process of photosynthesis. (54 -55) Sunlight is trapped by chlorophyll in the leaves. The leaves take in carbon dioxide. The roots take in water. The carbon dioxide and the water combine in the leaves using energy from the sunlight. Food (sugar) is formed. Oxygen is given off as a waste product through stomata in the leaves.

8. Why is photosynthesis so important? Photosynthesis is so important because without it, plants can’t make food and will die. Without plants, there wouldn’t be enough oxygen for people & animals to breathe (since plants give off oxygen during photosynthesis).

9. How are new plants created? (p. 56 -57; p. 64 -65; p. 68) New plants are created through spores and seeds. Given the right conditions, the seed will germinate and grow into a new plant.

10. How are seeds spread? (p. 69) Seeds are spread by wind, water, and catching onto animal fur/clothing. Some seeds are inside of fruit. An animal may eat the fruit and then the seeds are eliminated with its waste.

11. What is the life cycle of a plant? (p. 68 -69) The life cycle of a plant begins with a seed/spore. It germinates, grows into a seedling, grows into a mature plant, reproduces, and dies. New seeds/spores begin the cycle.

12. What is an adaptation and why is it important to living things? (p. 176) An adaptation is a trait that helps one kind of living thing survive in its environment. Without adaptations, living things might not survive. For example, in order to survive in the dry desert, a cactus needs a thick, waxy cover to keep water inside, and short roots to collect water when it rains.

13. Give some examples of other plant adaptations? (p. 175) * Water lilies have a long stem to allow them to reach the sunlight, and they have big leaves to collect as much sunlight as possible. Their roots help them absorb nutrients from the mud. * Vines have long stems that can cling to other objects to help its leaves reach sunlight.

* Know all the vocabulary in the chapter. (photosynthesis, stem, root hair, germination, spore, stomata, transpiration, adaptation) Good Luck!!
