Answer 1

Answer:

Germination involves three stages: Water is absorbed through the seed coat, the seed swells, and the seed coat splits open. Metabolism resumes. Water activates hydrolytic enzymes, which break down the seed's food supply into molecules the embryo uses for growth.

Step-by-step explanation:

When a seed starts to grow, we say it germinates. The cotyledons store food for the baby plant inside the seed. When the seed starts to germinate, the first thing to grow is the main root. The seed's growing conditions usually need to be damp, warm, and dark, like springtime soil. A dry seed will stay dormant until it soaks in some water, then it will start to germinate.

There are two different types of seeds: dicotyledons and monocotyledons. Dicotyledons are seeds with two parts and monocotyldons have only one part. You can call theses seed types dicots and monocots for short.

An example of a dicot would be a bean seed. A bean seed that has been soaked in water has a soft outer covering. This outer covering is the seed coat. Inside of the seed would be a tiny plant called the embryo. The two large parts of the seed are called the cotyledons. The cotyledons are stored food that the young plant will use while it is growing.

Monocots are seeds that have only one cotyledon, such as the corn seed. Monocots have a thicker seed coat that does not slip off easily like the bean seed. The corn seed does not split open like the bean seed, it stays in one piece. One cotyldeon surrounds the embryo and is called the endosperm.
