Monocot Germination Corn Seedling Carlson Stock Art
The ovule wall, which is made up of maternal cells called integument tissue, matures to become the seed coat. An example of a seed coat is the red or tan "skin" on a peanut. The ovary wall (note the important difference between the words "ovule" and "ovary") matures into the protective cover called the pericarp.

Structure of a Monocotyledon Seed. Monocotyledon seeds are found in the class of flowering plants known as Liliopsida. They're mainly herbaceous and their name derives from the seed structure, which shows a single cotyledon in its terminal position.Monocotyledon seeds are well-developed endosperms that can store starch and proteins that are essential for the early growth of the plant.

Importance. The embryo plant is protected by seeds, which allows it to develop once it finds adequate soil. Seeds are a protective structure that allows a plant embryo to live for a long time before germinating. Until the embryo's growing conditions are favourable, the seed can remain dormant.

Seeds of certain flowering plants may show specific characteristics resulting from convergent evolution that help in seed dispersal such as elaiosomes, a lipid and protein-rich fleshy structure attached to the seed coat. This food source - often of carunculate type - is especially coveted by ants, which take the seed to their nest to feed.

Seed Growth. In angiosperms, the process of seed development begins with double fertilization and involves the fusion of the egg and sperm nuclei into a zygote. The second part of this process is the fusion of the polar nuclei with a second sperm cell nucleus, thus forming a primary endosperm. Right after fertilization, the zygote is mostly.
