Aug 31, 2023 · A seed is the small, matured reproductive structure produced by plants, typically containing an embryo or young plant inside. Seeds are a crucial part of a plant’s life cycle as they serve as a means of reproduction and dispersal.
Feb 2, 2023 · A seed is a structure that encloses the embryo of a plant in a protective outer covering. Under favorable conditions of growth, a seed gives rise to a new plant, using the nutrients stored in them.
Definition of Seed: A true seed is defined as a fertilized mature ovule that possesses embryonic plant, stored material, and a protective coat or coats. Seed is the reproductive structure characteristic of all phanerogams.
Aug 3, 2023 · A seed is the fertilized matured ovule that possesses an embryonic plant, stored food material, and a protective coat that is viable and can germinate. A seed is a plant embryo in a dormant state and produced after the flower is fertilized.
- First Function: Propagation of The Plant by The Embryo
- Double Fertilization and The Endosperm
- Second Function: Storing Energy and Nutrients For Embryo Growth
- Third Function: Protecting The Embryo and Nutrients
In flowering plants the embryo is normally the result of fusion of egg and sperm. The egg is held within an ovule, which in turn is held within the ovary, which can hold several ovules, depending on the species. The egg is typically fertilized by sperm from pollen. The maturing ovule develops within the ovary of the maternal plant. A mature seed ha...
In flowering plants (angiosperms), there is a phenomenon called “.” The angiosperm pollen grain holds two sperm cells. One fertilizes the egg, and the resulting zygote grows to become the embryo. The other unites with two other maternal nuclei, called polar bodies, and these three nuclei together grow to become a tissue called endosperm (like the m...
Among flowering plants, energy and nutrients can be stored in the seed in the: 1. Cotyledon 2. Endosperm What types of energy and nutrients are stored in these tissues? Think about the seeds you eat, and you can probably name many of these nutrients. Carbohydrates 1. Provide energy — complex molecules composed of carbon, hydrogen, oxygen. 2. In pla...
Seeds have two layers of protection: 1. The seed coat, which originates as ovule wall tissue. 2. The , which originates as ovary wall tissue. The line drawing of a flower cross-section, right, shows sepals, petals, stamens (made up of a filament and anther), and carpel or pistil (made up of stigma, style, and ovary). Also identified are the ovary w...
Jul 27, 2022 · Basic seed morphology. Seeds have three main functions: Propagation of the plant. This is accomplished by the embryo, which is the nascent (new, young) plant resulting from the combination of genes from the male sperm, transmitted by the pollen, to the female egg, held in an ovule in the ovary.

Aug 29, 2022 · What is Seed? The seed is the part of the plant that contains genetic information. It is also known as germ or embryo. Seeds contain genes from parents and they are responsible for creating new plants. Seeds are tiny packages of genetic material that contain the instructions needed to create a new plant.
