Life Cycle Quiz

These diagrams show the life cycles of two plants. How are the life cycles of these two plants similar? In their life cycles, both plants–

• develop the same kind of flowers.

• have exactly four stages in their life cycles.

• have the same number of leaves as adults.

• begin life as seeds and grow larger.

These diagrams show the life cycles of a cockroach and a tenebrio. Which statement correctly compares these two life cycles?

• Both animals go through four stages of development.

• Neither the young nymph nor the larva has wings.

• Neither organism’s body changes as it develops.

• When both emerge from eggs, they look like adults.

The main function of the larval stage in animals such as the beetle is to–

• protect the eggs from predators.

• change and develop new body parts.

• store energy by constantly eating.

• reproduce and have offspring.

The life cycle of the tomato plant is illustrated here. Which stage in the diagram is the adult plant?

• A

• B

• C

• D

How is the life cycle of a beetle similar to the life cycle of a frog? Both life cycles–

• include a tadpole stage.

• produce adults with wings.

• take place in the water.

• begin with eggs.

One way in which a plant life cycle is like an animal life cycle is that both plants and animals–

• use seeds to reproduce.

• live for hundreds of years.

• lay eggs that hatch.

• grow larger over time.

The life cycle of a darkling beetle is shown here. Which stage represents the change from larva to adult?A

• A

• B

• C

• D

Which of the following organisms goes through metamorphosis, including the stages of egg, larva, pupa, and adult?

• Human beings

• Trees

• Beetles

• Lima beans

The lima bean plant that can produce the most offspring is the plant that produces the most–

• Leaves

• Seeds

• Roots

• Stems
