A seed has the following parts:

  • Seed coat: It is the outer covering the of seed. It protects the internal parts.
  • Seed leaves or cotyledons: Cotyledons are present inside the seed. Cotyledons absorb the food from the parent plant and store it for the embryo. They also protect the embryo. Some seeds have two seed leaves like gram, pea, bean, etc. Such seeds are called dicot or dicotyledonous. Some seeds have only one seed leaf. They are called monocot or monocotyledonous.
  • Embryo or baby plant: It is present inside the seeds which develop into a new plant. The embryo gives rise to a baby shoot (plumule) and root (radical).

Hydrochloric acid is present in the gastric juices in the stomach. The pH of the gastric juice is between 1 to 2. HCl has important role in the digestion process. HCl in the stomach causes the activation of enzymes. HCl is used to convert the enzyme pepsinogen into pepsin. Pepsin breaks up the peptides from the protein.

When we say that something is in motion, we usually mean that it is moving. But motion has a special meaning in science. In science, motion is a change in position compared to a place or an object that is not moving. The place or object that is not moving is called the frame of reference.
