• embryo

• endosperm

• testa

• ovule

• pollen grain

Embryo of a seed consists of :

• cotyledon

• hilum

• radicle

• plumule

• testa

Which structure that stores food which is used for germination of the seed?

• radicle

• plumule

• testa

• endosperm

What is the function of micropyle?

• Protects the seed
