1 The seed of a maple tree is inside a structure that is shaped like a wing. How does this structure help maple trees reproduce? It brings air to a growing maple seed. It allows the wind to carry a maple seed far away from the parent tree. It attracts birds, which fly the seed to new places. It feeds the growing maple seed. 2 Which of these plants does NOT use flowers to reproduce? pple tree Grass plant Fern ean plant 3 student cuts away a leafy branch from a house plant. She places the branch in water. fter a few days the branch grows roots and new leaves. Later, she plants the branch in a pot. It grows into a new plant. This process is an example of. asexual reproduction or vegetative reproduction sexual reproduction reproduction with flowers. selective breeding Macmillan/McGraw-Hill TKS Science Grade 5, hapter 2 1
4 Why do some plants produce flowers that have aromas? romas attract pollinators animals that spread pollen. romas attract animals that will eat the flowers. romas attract other plants. romas keep animals away. 5 Which of these traits is inherited from parent to offspring? In pea plants, the shape of the pea pod. In dolphins, jumping through a hoop for a reward. In house cats, coming to the kitchen when the Sun sets. In humans, riding a bicycle.

Use this illustration and your knowledge of science to answer Questions 6 and 7. Life ycle of a Grasshopper 6 oes a grasshopper undergo complete metamorphosis or incomplete metamorphosis? What does this mean? omplete metamorphosis, which means changing shape in many stages. omplete metamorphosis, which means changing from egg to nymph to adult. Incomplete metamorphosis, which means changing shape gradually. Incomplete metamorphosis, which means never changing into a true adult. 7 Which of these changes to the drawing would better model the life cycle of a grasshopper? dd the larval stage of the grasshopper. dd the pupa stage of the grasshopper. dd an arrow from nymph to egg. dd an arrow from adult grasshopper to egg.

Use this illustration and your knowledge of science to answer Questions 8 and 9. The Life ycle of a onifer 8 The cones of a conifer are most similar to what structures of a flowering plant? 9 What fact about the life cycle of pine trees can be inferred from the illustration? Flowers Leaves Seeds Pollen pine tree seedling needs 20 years to grow into an adult. pine tree makes equal numbers of male pine cones and female pine cones. pine tree grows best in cool, dry climates. Not every pine cone will make pine seeds that grow into new trees. Macmillan/McGraw-Hill TKS Science Grade 5, hapter 2 4
Use the illustration, the text, and your knowledge of science to answer Questions 10, 11, and 12. ay Time (minutes: seconds) 1 2:20 2 1:49 3 2:07 4 1:09 5 0:28 6 0:29 7 0:26 Every day for a week, a scientist places a mouse at the opening of a maze. t the end of the maze is a piece of cheese. The scientist uses the stopwatch to time how long it takes the mouse to reach the cheese. She records the results in a chart, as shown here. NOTE: The hand of the stopwatch makes a complete circle every 60 seconds. 10 What kind of behavior is the mouse demonstrating? 11 Which of these questions do the results best answer? Inherited behavior Learned behavior Hydrotropism Phototropism oes the size of a maze affect how quickly a mouse could run through it? an a mouse change the way it behaves from one day to the next? ould a mouse travel through the maze in this experiment in less than 26 seconds? How fast can a mouse run? Macmillan/McGraw-Hill TKS Science Grade 5, hapter 2 5
12 When the scientist timed the mouse on ay 1, how far did the hand of the stopwatch travel? One and a half times around the face of the watch. Two and one-third times around the face of the watch. Five times around the face of the watch. From the 0 numeral on the watch to just beyond the 2. 13 How does camouflage help an animal survive? amouflage lets an animal blend into the background, making it hard to see. amouflage helps an animal find food. amouflage helps the animal find others of its own kind. amouflage offers protection, the way a hard shell protects a turtle or crab. 14 fter a forest fire or the eruption of a volcano, how do mosses help other plants? Mosses become the main food for other plants. Mosses carry seeds for other plants. Mosses are the first plants to return to the land, and they prepare it for other plants to grow. Mosses take the place of leaves on burnt trees. Macmillan/McGraw-Hill TKS Science Grade 5, hapter 2 6
