Question

What do you call the food laiden tissue present in the developing seed?
In a germination seed, the radical emerges before the plumule, why?
Suggest a reason for overnight soaking of the seeds before the start of experiment.

Answer 1

Answer:

Seed. A seed is a small embryonic plant enclosed in a covering called the seed coat, usually with some stored food. ... This tissue becomes the food that the young plant will consume until the roots have developed after germination, or it develops into a hard seed coat.

In botany, the radicle is the first part of a seedling (a growing plant embryo) to emerge from the seed during the process of germination. The radicle is the embryonic root of the plant, and grows downward in the soil (the shoot emerges from the plumule). ... Eventually, it causes death of the seedling.

If it is too cold or too wet, too warm or too dry for that particular seed, it will fail to germinate at all. By soaking seeds ahead of time, you remove some of those barriers so that the seeds are ready to sprout by the time you stick them in the soil.

Answer 2

What do you call the food laiden present in the developing seed?

The food laiden tissue, either present on one side of the embryo or surrounding the embryo on either sides in endosperm.

In a germination seed, the radicle emerges before the plumule, why?

The radicle emerges before the plumule because it needs to penetrate into the soil to facilitate water absorption for the growing embryo.

Suggest a reason for overnight soaking of the seeds before the start of experiment.

During soaking, the cotyledons absorb water from the container and become actively germinating.
