Seed Structure and Germination Concepts

The video tutorial explains the difference between monocotyledon and dicotyledon plants. It begins by describing the germination process of wheat and bean seeds, highlighting the structural differences. Bean seeds have two cotyledons that provide nutrients, while wheat seeds have one cotyledon with limited nutrients. The video further classifies plants based on these seed structures, explaining how they affect plant development.

What is the main difference between monocot and dicot seeds?

• Monocot seeds have one cotyledon, dicot seeds have two.

• Monocot seeds have two cotyledons, dicot seeds have one.

• Monocot seeds have one cotyledon, dicot seeds have none.

• Monocot seeds have no cotyledons, dicot seeds have one.

What happens first when dry seeds absorb water?

• The seed coat hardens.

• The seed coat breaks.

• The seed swells and the radicle emerges.

• The seed absorbs oxygen.

What is the primary function of the cotyledons in bean seeds?

• To absorb water.

• To facilitate gas exchange.

• To protect the seed.

• To provide nutrients for the seedling.

Which of the following seeds is NOT similar to bean seeds in structure?

• Apple seeds

• Soybean seeds

• Cotton seeds

• Wheat seeds

What is the main nutrient storage in wheat seeds?

• Embryo

• Seed coat

• Endosperm

• Cotyledons

Which part of the wheat seed is responsible for nutrient storage?

• Radicle

• Seed coat

• Endosperm

• Cotyledon

What is the first leaf that emerges from a wheat seed called?

• Hypocotyl

• Radicle

• True leaf

• Cotyledon

How do the cotyledons of bean seeds change after germination?

• They remain underground.

• They become the first true leaves.

• They wither away.

• They turn into roots.

How do botanists classify plants based on seed structure?

• By the size of the seeds.

• By the color of the seeds.

• By the number of cotyledons.

• By the shape of the seeds.
