Question

Why are Angiosperms so called? I which structures do the seeds develop ? Why are cotyledons considered an important part of seed?

Answer 1

Dear student,

The term 'Angiosperm' has been derived from greek composite word (angeion-, "case" or "casing", and sperma, "seed") which means "enclosed seeds". Thus, angiosperms means those plants that produces seeds within an enclosure, i.e., they are fruiting plants.

Angiosperms have carpel that encloses developing seeds that may turn into a fruit, i.e., their reproductive structures are flowers in which the ovules are enclosed in an ovary.

A cotyledon is part of the embryo within the seed of the plant.They are the first part of the plants to emerge from the soil and gives way for other plant growth. Some cotyledons may last only for few days, while others may last for years.
The cotyledons are important for the new growing plant because they contain the stored food from the seed which is required for the initial burst of energy to grow.

Regards.
