Parts of a Seed and Germination

A mature seed consists of :

• 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

• Stores the food for germination

• Grows and develops into roots

• Allows air and water to enter the seed

Choose the correct pairs of function and structure of seed

• Testa - stores food

• Cotyledon - protects the seed

• Plumule - grows and develops into shoot

• Radicle - grows and develops into roots

• Hilum - attaches the seed to the fruit

Epigeal germination occurs where cotyledons are carried _______________

• below the ground

• above the ground

• inside the ground

When cotyledon remains under the ground during germination, it is known as ___________

• epigeal germination

• hypogeal germination

• ground germination

• under germination

Choose the conditions required for germination of seeds :

• Suitable temperature

• Light

• Air

• Water

• Nutrient
