First of all, the seed imbibes water and gets its enzymes activated. Active metabolism in the seed is resumed and cell division starts in the radicle and plumule. The radicle comes out of the micropyle first followed by the plumule. Thus sprouting in the seed takes place.
The cotyledon of the seed develops into a seedling at the time of germination.
Germination refers specifically to the process that occurs from seed to seedling, not directly to a mature plant. During germination, a seed absorbs water, swells, and eventually breaks open, allowing a seedling to emerge. The seedling then develops further into a sapling and eventually matures into a full plant. Thus, germination marks the initial phase of growth from seed to seedling.
The embryo
seed leaves provide food for the seedling
True. A seedling uses sugars stored in its seed leaf (cotyledon) as a source of energy during its early growth stages until it develops its own leaves for photosynthesis.

The embryo
photosynthasis
A plummule is a term used to describe the embryonic shoot or bud of a plant that develops from the plumule of a seed. It is the part of the seedling embryo that will eventually give rise to the stem and leaves of the plant as it grows.
seed leaves provide food for the seedling
A seed eventually develops from a fertilized plant egg. A seed is the mature fertilized egg cell of a plant. It is the embryo developing from the fertilized plant egg. The seed, however, develops from the ovule during embryo formation in it.
True. A seedling uses sugars stored in its seed leaf (cotyledon) as a source of energy during its early growth stages until it develops its own leaves for photosynthesis.
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.
The stored food inside the seed is used up by the seedling. Seedling after establishing itself as a new plant starts absorbing nutrients and water with the help of its root and starts synthesizing its own food by photosynthesis.
When the seed begins to grow, it is called germination. Germination is the process where a seed starts to sprout and develop into a young plant.
