Development and Provisioning of Seeds

Seeds are formed through the process of arrested development, which is essential for their development.
Male gametophytes develop inside the sporophyte plant and are dispersed in a dormant state until they reach a female gametophyte for fertilization.
After fertilization, the zygote quickly develops into an embryo with root/shoot axis, apical meristems, and cotyledons.
The development of the embryo in seeds ceases, with no cell division or differentiation, but metabolic rate drops and tolerance to extreme conditions increases.
Seeds are provisioned with nutrients that supply energy for cellular respiration and materials for plant cell construction.
Materials can be stored in the female gametophyte, the embryo's cotyledons, or the endosperm tissue found in angiosperms.
Nutrients in seeds are supplied by the parent plant via phloem tissue, which is connected to each seed through vascular traces.
Seeds are packaged with an embryo and stored food inside a seed coat, which develops from the integuments of the parent plant's sporophyte tissues.
The development of a seed involves the development of the zygote into an embryo, the transformation of the ovule's sporophyte tissues into a seed coat, and the development of nutritive tissue.
The nutritive tissue in seeds proliferates and expands to supply materials to the seed after dispersal.
The development of seeds is crucial for the survival and growth of plants, as it allows them to produce structures that can obtain matter and energy on their own.
The specific provisioning and packaging of seeds vary between different plant species.
