​

​Trunk

​The stem of a tree is called trunk and is covered with bark.

​

​

Leaves

• ​Capture sunlight to make food for the plant.

• This process is called photosynthesis.

​

​

​Leaves

​

​

​FLOWER

• They are the reproductive part of most plants.

  It is in the flower that seeds start to grow.

• Their petals are colorful to attract insects.

​

​

FLOWERS

SEEDS

• They are the reproductive part of most plants.

  It is in the flower that seeds start to grow.

• Their petals are colorful to attract insects.

​SEEDS

• ​Seeds are the part of the plant that make new plants.

• When they germinate (start to grow), they will develop into new plants.

​

​

• ​Seeds form in fruits

​

​

​FRUIT
