Multiple choice

Which part of the grain contains the embryo?

  1. Pericarp

  2. Endosperm

  3. Scutellum

  4. Coleoptile
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The scutellum is a small shield-shaped structure located at the base of the embryo. It contains the embryo's food reserves and helps to absorb nutrients from the endosperm.

Multiple choice

What is the function of the pericarp?

  1. Protects the grain from damage

  2. Stores food reserves

  3. Absorbs water and nutrients

  4. Produces hormones
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The pericarp is the outermost layer of the grain and it protects the grain from damage. It is composed of several layers of cells, including the epidermis, the hypodermis, and the mesocarp.

Multiple choice

What is the function of the coleoptile?

  1. Protects the plumule

  2. Absorbs water and nutrients

  3. Produces hormones

  4. Stores food reserves
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The coleoptile is a sheath that protects the plumule as it emerges from the soil. It is composed of several layers of cells, including the epidermis, the hypodermis, and the mesocotyl.

Multiple choice

What is the function of the aleurone layer?

  1. Protects the endosperm

  2. Stores food reserves

  3. Produces hormones

  4. Absorbs water and nutrients
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The aleurone layer is a thin layer of cells that surrounds the endosperm. It produces hormones that regulate the growth and development of the grain.
