What is the function of the seed coat and the cotyledon?
The cotyledons provides a source of food to the seed and seedling that is germinating, while the seed coat protects it.
What observations indicate that a seed has germinated?
The seed coat has busted and the seedling is beginning to emerge
What is the function of a seed coat and the cotyledons?
The seed coat protects the seed from mechanical damage, pathogens, and dehydration during dormancy. Cotyledons are the embryonic leaves in a seed that provide nutrients to the seedling until it can produce its own food through photosynthesis.
What happen to a germinating seed?
The contents of a seed are used up after germination by the seedling growing from it.
Why did my avocado seed split in half?
Your avocado seed split in half because of internal pressure caused by the growing seedling inside. This is a natural process as the seedling expands and pushes against the seed coat, eventually causing it to split open.
How does the seed absordb water?
Seeds absorb water through a process called imbibition, where water is taken in by the seed coat and then absorbed by the seed's cells. This initial hydration triggers metabolic processes that lead to germination and seedling growth. Absorption of water is essential for activating enzymes, softening the seed coat, and providing necessary nutrients for the growing seedling.
When does germination happen?
Germination happens between the seed and seedling stages of the plant.
Which one is not part of a seed?
Roots are not part of a seed. Seeds typically consist of the embryo, endosperm, and seed coat. Roots develop after germination when the seedling starts to grow.
How do seed leaves help the seedling?
seed leaves provide food for the seedling
What are the three main parts of an angiosperm seed?
The three main parts of an angiosperm seed are the seed coat, the endosperm, and the embryo. The seed coat provides protection for the embryo, the endosperm serves as a source of nutrients for the developing seedling, and the embryo contains the future plant in a dormant state.
Why can seeds from cone trees stay on the soil for a long time?
Any seed has a hard coat thet protects the seed until the conditions for germination are suitable for survival of the seedling.
Which part of the seed develops into a seedling at the time of germination?
The cotyledon of the seed develops into a seedling at the time of germination.
