Plants

Question 1

Flowering plants

Answer 1

In a map, the green parts are the rainforests, the yellow parts are drier, and they are where the grass grows. The orange parts are where the desert places are.

Question 2

Organs

Answer 2

A. Leaves

Leaves absorb energy from sunlight and make the
plant’s food.

B. Stem

The stem transports water and food and supports the
leaves and flowers

C. Roots

Roots hold the plant in place and absorb water and
minerals from the soil.

D. Flowers

Flowers produce seeds so that the plant can reproduce

Question 3

Extra functions

Answer 3

A cactus doesn’t have leaves like most plants – instead, it has spines to protect it. Its green stem takes over the job of making food. The swollen stem also stores water to keep the plant alive. Mangrove roots point upwards instead of down to collect air, so mangroves can grow in muddy water.

Question 4

Lost organs

Answer 4

Plants that are parasites don’t make their own food as most plants do. Their roots steal food and water from other plants. They don’t need leaves or green stems – they send up flowers when they need to reproduce.
