The fetus or embryo of every living being is formed by the process of mixing between male sperm cells and female ovum. Does it also apply to plants?. Yes, so is the case with plant embryos formed from the mixing process between male sperm cells and female plant eggs.
Flowers are part of the plant as an organ of breeding and fruit formation.
Some types of plants are of two kinds, so they are called perfect flowers that have male organs and female organs in one flower, as in pea. In addition, there are also types of flowers that only have one gender only. he has only male or female only, as in the flowers of corn trees. flowers on plants are protected by the leaves of trees that protect themselves so as to keep the organ of breeding on trees.The leaves surround and protect it from every direction, besides the leaves also have other functions, such as providing stimulation to the insects to visit the flowers.
sperm cells in a pollen plant located within the sacs at the end of the flower stalk, and are called with stamens, when the Sari flour begins to ripen the sacs open so as to make the flour underneath a breeze or insect.
The female genitalia of flowers in plants are in the middle and surrounded by the sex of male sex that many and named with the pistil.
The pistil consists of three parts:
- Stigma (the top of the flower).
- Pen.
- ovaries. In the (ovaries) embryo embryo grows until it becomes ripe fruit.
The process of pollination in plants occurs when Sari flour encounters the pistils in the flower, either from the same flower or from other flowers of the same kind. Pollen grains of various shapes, colors, large and types.
Pollination occurs when the flour Sari meets the pistil, both on the same flower as well as on other similar flowers.
In the grains of flour Sari there are 2 small cells, one of which is the male Sel. Just when it comes to the stigma of interest of the same kind will take place reacting. Then, it will come out of every seed of a long pipe that gradually in the stigma then into the pen, and eventually reach the ovary at the base of the flower. Through the pipe, the male cells divide into two cells arriving at the ovary in which there is an egg cell, as in some types of planting. each egg has a hole which is the entrance for the male cell to meet an egg in an extraordinary system. From it, seeds and fruits are formed.
We find that each plant is in pairs (male and female). Similarly, male cells in plants in pairs, it could be the meaning of the content of the creation of flowers.
