End Of Year Science Review

The 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

Adult plants reproduce by producing seeds. These seeds grow to become new plants. Which stage in a frog’s life cycle is most similar to a plant seed?

• Egg

• Tadpole

• Froglet

• Adult from

The diagram shows the life cycle of a lady beetle. Which stage is missing from the lady beetle’s life cycle?

• Pupa

• Larva

• Egg

• Adult

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 have 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.

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

• 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

This diagram illustrates the life cycle of a tomato plant. Which stage in this plant life cycle is the adult?

• A

• B

• C

• D
