what is necessary for seed formation in plants?

Seeds are the product of the ripened ovule, after fertilization by pollen and some growth within the mother plant. The embryo is developed from the zygote and the seed coat from the integuments of the ovule.

Plants need water to support cell structure, for metabolic functions, to carry nutrients, and for photosynthesis. Plant cells need essential substances, collectively called nutrients, to sustain life. Plant nutrients may be composed of either organic or inorganic compounds.

Viable seeds are living entities. They must contain living, healthy embryonic tissue in order to germinate. All fully developed seeds contain an embryo and, in most plant species, a store of food reserves, wrapped in a seed coat.

While soil depth, temperature, and water are all required for germination, sunlight is not required until after the seedling has emerged from the soil surface.

Nutrients needed in large amounts. The three main examples required for plants include Nitrogen, Phosphorus, and Potassium. Promotes growth of healthy leaves.

Plants have specific needs - light, air, water, nutrients, and space - to survive and reproduce. Almost all plants need these five things to survive: Light.

The three principal organs of seed plants are roots, stems, and leaves. These organs perform functions such as the transport of nutrients, protection, and coordination of plant activities.

Requirements for growth Plants need air, light, warmth, water and nutrients to be healthy. If a plant doesn't have one of these requirements it could affect its growth or even die.

In seed plants, haploids can be derived from tissue culture of gametic cells (microspores that develop into male gametes borne in pollen grains or megaspores that develop into female gametes within the pistil of a flower,) occurring in the anthers or ovules of flowers or by wide crosses.

Plants need five things in order to grow: sunlight, proper temperature, moisture, air, and nutrients. These five things are provided by the natural or artificial environments where the plants live. If any of these elements are missing they can limit plant growth.

Seeds: specialized dispersal stage of the life cycle. The seeds produced by the sporophyte contain: A seed coat of diploid tissue from the original diploid parent. A developing diploid embryo inside which began as a zygote after fertilization of the haploid egg by a haploid sperm.

Requirements for growth Plants need air, light, warmth, water and nutrients to be healthy. If a plant doesn't have one of these requirements it could affect its growth or even die. For example, a plant that is kept in a dark place will grow tall and spindly in search of light and then become weak and die.

In flowering plants, the gametophyte generation takes place in a flower, which forms on the mature sporophyte plant. Each male gametophyte is just a few cells inside a grain of pollen. Each female gametophyte produces an egg inside an ovule.

C is correct. While soil depth, temperature, and water are all required for germination, sunlight is not required until after the seedling has emerged from the soil surface.

Not every plant grows from a seed. Some plants, like ferns and mosses, grow from spores. Other plants use asexual vegetative reproduction and grow new plants from rhizomes or tubers. We can also use techniques like grafting or take cuttings to make new plants.

Like angiosperms, gymnosperms also have vessels and companion cells. The vascular system is common for the both of them, consisting of conjoint and vascular bundles (open and collateral). The ovules of both angiosperms and gymnosperms develop into seeds. Their mode of seed germination is epigeal, hypogeal, or both.

Seeds contain all the starting materials necessary to develop into complex plants. Because of this, they are extremely nutritious. Seeds are great sources of fiber. They also contain healthy monounsaturated fats, polyunsaturated fats and many important vitamins, minerals and antioxidants.
