seed germination process by love Lina Rajeev I found this on website Buzzle
com bu z z le comm most plant life starts from the humble seed life begins
from the seed for all plants alike to reproduce itself and evolve with time is
what a seed offers to the ecosystem and many trees plants and flowers bear
witness to this fact a seed is basically a kernel that encloses in itself a small
embryonic plant covered by a hard seed coat and some stored food that upon
receiving the appropriate climate conditions will promote growth the seed
is the ripened ovule or egg fertilized product of gymnosperm and angiosperm
plants this is the end product of the pollination process in which the embryo
develops from the zygote and the seed coat from the outer covering of the
ovule the ability to consistently unsuccessfully reproduce itself makes
trees and plants that use their seeds for propagating themselves have a higher
survival rate than the ones which rely on cuttings runners shoots or rhizomes
let us understand this amazing ability by reading through the germination
process seed germination process the seed contains an immature plant called
an embryo that resembles an adult plant complete with leaves and a root the
seeds leaves are called the cotyledons seeds that contain one embryonic leaf
are known as monocotyledons or monocots seeds with two embryonic leaves are
termed dicotyledons or dicots the food found in the seed which nourishes the
embryonic seedling during the early stages of development is known as the
endosperm there are certain basic steps of seed germination for a seed to
germinate successfully first the right conditions are required
although most seeds will germinate under different conditions the plants or trees
will not come true as it is the quality of the seed that matters not its age
lotus seeds as old as 2,000 years have germinated as the quality of their
embryo was preserved moisture or water is needed by the dried seeds to resume
their cellular metabolism and growth moisture combined with warmth triggers
growth which is probably the reason why sown seeds should be kept in a warm
place warmth increases humidity which ensures enough moisture to the seeds the
size of the seed and the depth it is sowed determines how quickly it will
sprout through the soil the larger the seed the more energy stored in it and
vice versa this is the reason why large seeds are so deeper in comparison to
small seeds soil matters as the seed takes its oxygen from its pores and the
right temperature will accelerate its growth whether a seed needs light full
or partial or darkness to sprout depends upon its individual physiological need
the dormancy level of the seeds also determines the time it will take to
germinate another way to germinate seeds is by growing seeds without soil
germination of seeds once the conditions have been satisfied for the process of
seed germination it is just a matter of time that they turn into a seedling some
seeds especially the ones with hard coats like the sunflower Morning Glory
dates a corn corn etc need a couple of hours pre-soaking to speed up the
germination of seeds after the seeds are sowed and the soil misted with water the
water is absorbed by the seeds through its coat and provides moisture to the
embryo nestled in it this activates enzymes that help in
duplication of plant cells and also gets them to use the energy or food stored in
the sea to start nourishing the embryonic plant with all the nourish
the embryo becomes too large and bursts open through the seed coat in search of
light to start its process of photosynthesis and thus the growing
plant emerges during the same time even the roots sprout and head down in search
of more food from the soil both the root and the plant chute moved downwards and
upwards simultaneously and respectively in no time then you see the seedling
forced its way through the soil the seed germination process is amazing to watch
and understand the way it reproduces and insures its species survival so go ahead
and sew a few seeds and watch how life sprouts from the soil
