Seed Structure and Function Assessment

The video tutorial explains the structure and function of dicot seeds, focusing on the embryo, cotyledons, and seed coat. It outlines the materials required and provides a detailed procedure for examining and dissecting seeds of bean, gram, and pea. The tutorial also highlights the importance of soaking seeds and taking precautions to avoid damage during dissection. Key concepts include the role of the micropyle and hilum in seed germination and the identification of dicot seeds by their two cotyledons.

What are the three basic parts of a typical seed?

• Embryo, micropyle, and seed coat

• Embryo, seed coat, and hilum

• Embryo, nutrient storage, and seed coat

• Embryo, seed coat, and cotyledons

What is the primary function of cotyledons in seeds?

• To protect the seed

• To store nutrients for the embryo

• To absorb water

• To attach the seed to the fruit

Which of the following is NOT a material required for the seed examination experiment?

• Dissecting microscope

• Forceps

• Distilled water

• Thermometer

What shape is the bean seed described as having?

• Oval

• Square

• Round

• Kidney

What is the function of the micropyle in seeds?

• To store nutrients

• To absorb water

• To protect the embryo

• To attach the seed to the fruit

What is the role of the plumule in the embryo?

• Develops into the shoot

• Stores food

• Protects the seed

• Develops into the root

What does the radicle develop into?

• The cotyledons

• The root

• The shoot

• The seed coat

How many cotyledons are present in dicot seeds like bean, gram, and pea?

• Three

• Four

• One

• Two

What precaution should be taken when removing the seed coat?

• Use a thermometer

• Avoid damaging the seed

• Ensure the seed is dry

• Soak the seed in hot water

Why should seeds be soaked overnight in distilled water?

• To allow them to absorb water

• To make them easier to handle

• To remove the seed coat

• To change their color
