How Seeds are formed – Animated | REPRODUCTIVE ORGANS OF PLANTS | POLLINATION FERTILIZATION – Botany


Hello Friends, Today we will look into the
Concept of Seed Formation in a Plant and also learn about Male and Female Reproductive Organs
of a Plant, Pollination and Fertilization process similar to humans and animals, and
in the end about Artificial Pollination. Plants reproduce using eggs (ova) and sperms,
just like humans and animals. Male plants release pollen grains, which fertilize
the ovaries. The fertilized ovaries develop into seeds
which are like zygote and embryo, which are either dispersed naturally either by wind
or animals or if planted into soil by humans grow into new plants. So keeping this concept in mind for the formation
of seeds or to collect your own seeds from your garden and for plant propagation, you
must also know few more concepts and terms of botany in gardening. The Flower:
The flower is the reproductive unit of many plants. To understand the reproductive organs of a
plant, the parts of the flower should be known which include petals, sepals, The Carpels
and Stamens. The External Parts of the flower are the Petals
and Sepals. Plants or Flowers can be unisexual or bisexual
also called hermaphrodites similar to certain genders in humans, Bisexual (also called Perfect
Flowers) meaning their flowers have both male and female parts in the same flower. And Unisexual (also called Imperfect Flowers),
meaning they have only one ograns � either male or female. Most Flowers are bisexual, and we shall study
the anatomy of a flower and different parts of a flower in this illustrated diagram. What parts are The Male Reproductive Organs:
Stamens are the male reproductive parts of flowers. A stamen consists of an anther � also called
pollen boxes (which produces pollen) and the filament. The pollen consists of the male reproductive
cells and these fertilize ovules. What Parts are The Female Reproductive Organs:
The pistil is the collective term for the carpel. Each carpel or the female part includes a
stigma (which receives the pollen during fertilization) and a style (a tube on top of the ovary). And an ovary (where the ovules are produced;
ovules are the female reproductive cells, or the eggs). So that was the illustration on the reproductive
parts of a flower. 1. Pollination & Fertilization: Pollination is
the process by which pollen grains are transferred to the female reproductive organs of a plant,
thereby enabling fertilization to take place. This can be compared to Copulation in animals
and Fertilization is the same terms used for formation of zygote in animals and humans. Pollination can be either Natural or Artificially
done by humans. In case of Bisexual or Perfect Flowers, pollination
happens within the same plant and then seeds are formed and this is called Self Pollination. If this happens from one plant to a different
plant its called Cross Pollination. Well we will not go into the depths of these. The Point you must note is you must not prevent
or drive away or even kill the natural pollinators or insects like honey bees and butterflies
which are useful agents in gardening and plant reproduction. These insects are called Pollen Vectors. These insects like honey bees and butterflies
fly from flower to flower collecting sweet nectar. As they visit flowers, they spread pollen
around, depositing it on some stigmas. After a male’s pollen grains have landed on
the stigma during fertilization, pollen tubes develop within the style, burrowing down to
the ovary, where the sperm fertilizes an ovum (an egg cell), in the ovule. After fertilization, the ovule develops into
a seed in the ovary. Also Artificial pollination is an interesting
topic in gardening. Here we humans intervene with the natural
pollination process. We take out the pollen grains or plant sperms
from one flower and transfer to another, allowing the pollen to fertilize the ovaries and create
seeds that will develop into fruits and then new plants. We shall not go into details of these at present
and our main purpose of this video is, specially for newbie gardeners, to clear the concept
of How plants reproduce and how seeds are formed in plants and this is called sexual
propagation. Asexual propagation is another topic � most
of us grow plants from cuttings and this is the best example of asexual propagation. Well, Folks that�s all in todays video. Please give a thumbs up if you like the video
