Plants and Animals Test Review

1. Plants and Animals Test Review

2. Plants A and B are adult plants. Plant C is a seedling. Which adult plant did the seedling come from, A or B? Plant B Plant A Plant C

3. Plant C How do you know?

4. List the 4 main parts of a plant!

5. 4 main parts of a plant are… • Flower • Stem • Leaf • Roots *Which part does an adult plant have that a seedling does NOT have?

6. A seedling does not have… • Flowers! *What do flowers DO?

7. A flower… • makes seeds. • makes pollen. • helps the plant to make new plants.

8. The life cycle of a flowering plant has four stages. • List them in order!!!

9. The stages are… • Seeds are in the fruit. • The seed germinates. • The seed becomes a seedling. • The seedling is an adult plant.

10. What are 3 things a plant needs to grow?

11. 3 things a plant needs to grow are… • Energy from the sun/sunlight • Water • Soil/minerals

12. How does water move through a plant? • Clue: Plants need leaves, stems, and roots to grow.

13. Water moves through a plant by… • Water moves through the ground to the tiny root hairs. • Water travels through tubes of the plant up the stem. • From the stem, the water moves into the leaves where food is made.

14. How does a plant make food? • Use the words… • Carbon dioxide • Water • Sugar • Oxygen • Energy • Sunlight

15. Plants make food by… • Carbon Dioxide enters the plant through the leaves. • The leaves use energy from the sunlight to change carbon dioxide and water into sugar and oxygen.

16. Many plants in a pond died. What might happen to the fish in the pond? • A. They might migrate to a new place. • B. They might start making their own oxygen. • C. They might grow bigger because they have more space. • D. They might die because they do not have food.

17. D. They might die because they have no food! • If plants feed off of the food and there are less plants than normal, the fish will die. • Remember: If one part of a food web is affected, everything is!

18. Which of the following is a consumer in a forest food chain? • Fruit • Moose • Sunlight • Maple tree

19. B. Moose! • A moose is a consumer because it eats producers (plants). A moose cannot make its own food.

20. How does a turtle’s shell help it survive? • A. The shell is an adaptation for getting food. • B. The shell protects the turtle from predators. • C. The shell helps the turtle meet its need for oxygen. • The shell helps the turtle copy a poisonous animal.

21. B. The shell protects the turtle from predators! • A turtle’s hard shell makes a great escape from its predators. A shell does not help an animal get food or get oxygen. A shell is also not a type of mimicry.

22. Scientists discover a fossil of a dinosaur footprint. He wants to measure its length and width. Which tool should he use? • Graduated cylinder • Metric ruler • Pan balance • Stopwatch

23. Metric Ruler! • A ruler helps to measure length and width. • A stopwatch measures time. • A pan balance measures weight. • A graduated cylinder measures volume.

24. How are tadpoles and adult frogs alike? • Both have legs. • Both have lungs. • Both are vertebrates. • Both use gills to breathe.

25. Both are vertebrates! • Both a tadpole and a frog have backbones!

26. Look at the food chain below. Sunlight  ?  Sheep Which living thing is missing in the food chain? • Mouse • Eagle • Grass • Wolf

27. Grass! • The only living thing listed that a sheep would eat is grass. Grass also gets its energy from the sunlight.

28. Algae get energy from sunlight. Fish get energy from algae. Otters get energy from fish. Which of these is a producer? • Algae • Fish • Otters • Sunlight

29. Algae! • Algae is able to make its own food by using energy from the sun. Algae is the only producer listed.

30. The kind of fern that made the fossil in the drawing below is extinct. What is true about the extinct fern and a fern that lives today? • They are exactly alike. • They both have flowers. • They are similar to each other. • They have nothing in common.

31. They are similar to each other! • They do have something in common. Doesn’t the fossil look fairly similar to a fern today? Hmm… but it’s not exactly the same…

32. In a grassland ecosystem, ferrets eat prairie dogs and other animals. Suppose some of the prairie dogs become sick and die. What will happen to the ferret population? • The population of ferrets will grow. • The population of ferrets will be reduced. • The population of ferrets will stay the same. • The population of ferrets will become extinct.

33. The population of ferrets will be reduced! • The ferrets will not become completely extinct because not all of the prairie dogs have died, only some. • The population will not stay the same because their food supply has changed. • Remember: If one thing changes in a food chain/food web, everything changes!

34. A student is studying the parts of a plant. She is looking at the part that holds the plant in the ground. Which part is she observing? • Flower • Leaf • Root • Stem

35. The root! • The root is what holds the plant in the ground and keeps it from blowing away. It also takes up the water for the plant.

36. Yahoo! You finished! • Good luck on your test! • Take your science book home to study.
