The Seed

The video tutorial explains the formation and structure of seeds, highlighting the process from fertilization to seed development. It covers seed dormancy, germination, and the role of endosperm in nourishing the embryo. The tutorial distinguishes between exalbuminous and albuminous seeds, and describes the basic parts of a seed. It also compares monocot and dicot seeds, detailing their unique structures and functions.

• Exalbuminous seeds

• Perispermic seeds

• Monocot seeds

In a dicot seed, what is the region between the radical and the cotyledons called?

• Coleoptile

• Scutellum

• Hypocotyl

• Epicotyl

What is the function of the coleoptile in monocot seeds?

• To store food for the seed

• To protect the plumule during growth

• To absorb water for germination

• To anchor the seed in the soil

What is the Latin term for the cotyledon in grasses, and what does it mean?

• Epicotyl, meaning above the cotyledon
