semínky
Semínky, also known as seeds, are the reproductive units of flowering plants. They are typically small, hard, and often covered in a protective coat called the seed coat. Seeds are produced within the ovary of a flower after fertilization, which occurs when pollen from a male flower fertilizes the female flower's ovule. The fertilized ovule develops into a seed, which contains an embryo and a food supply for the embryo's growth.
Seeds can be dispersed in various ways, including by wind, water, animals, or even human activities. This
The structure of a seed varies among different plant species. Generally, a seed consists of the following
1. Seed coat: The outer protective layer that shields the seed from environmental damage and pathogens.
2. Embryo: The developing plant contained within the seed, consisting of the root, stem, and leaves.
3. Endosperm: A nutrient-rich tissue that provides food for the embryo during germination.
Seeds play a crucial role in the life cycle of plants and are essential for their reproduction
