DENDROLOGY

Detailed explanation-1: -A seedling is a young plant or sporophyte developing out of a plant embryo from a seed. Seedling development starts with germination of the seed. A typical young seedling consists of three main parts: the radicle (embryonic root), the hypocotyl (embryonic shoot), and the cotyledons (seed leaves).

Detailed explanation-2: -Seedling is a young plant, especially one coming out from seed and not from cutting. A seedling develops out of a plant embryo from a seed.

Detailed explanation-3: -A fertilized ovule develops into a seed. Seed has the embryo within it which contains a plumule and radicle. Embryo is formed from the zygote which is formed when the egg is fertilized by the male gamete. Plumule and the radicle develops into a shoot and the root, respectively.

Detailed explanation-4: -The seed is the embryonic stage of the plant life cycle. Most seeds consist of three parts: embryo, endosperm, and seed coat. The embryo is a tiny plant that has a root, a stem, and one or more leaves. The endosperm is the nutritive tissue of the seed, often a combination of starch, oil, and protein.
