What items are soaked before cooking in your home? Why?
In
my house mung, chana, tuwer, chola, wal, vatana, rajma, rice etc. are soaked
before cooking. The darna which is very hard takes more time to cook. Soaking
the grains makes them slightly softer and takes less time to cook.
What
sprouts do you eat? How is it measured? How long does it take?
In
my house mung, gram and matha are sprouted and eaten. They are soaked in water
overnight. In the morning he is taken out of the water and wrapped in wet
clothes. Chickpeas take two days to sprout, while mung and mutton take less
time.
Has
a doctor advised you or someone around you to eat sprouted beans? Why?
Yes,
a few months ago my father was advised by the doctor to eat sprouted beans. He
had been ill for fifteen days and had become weak. Sprouted beans are
nutritious. It is useful in generating new cells in our body, growing them and
increasing the immunity of the body.
In
which bowl the seeds have sprouted? What differences can you see between this
bowl and the other bowls?
Shoots
have sprouted only in pot number two. The seeds in the remaining two pots did
not germinate. This is because the chickpeas in bowl number 2 got both water
and air. While the chickpeas in bowl number 1 got more water than required, but
did not get air. The chickpeas in bowl number 3 got only air. No water was
found. Thus, air and water should be available in sufficient quantity for
sprouting.
Why
did Gopal's mother wrap the soaked gram in a wet cloth?
Gopal's
mother tied the soaked chickpeas in a wet cloth to germinate them (Akurit), so
that the chickpeas can get both water and air.
The
whole tuber germinates, but the tuber lentil cannot be germinated. Why so?
Whole
Tuvar is the seed of the Tuvar plant. of that seed is an inactive state. It
germinates by getting water, air and suitable space. Tuwer dal is not a natural
tuwer seed. Tuvar dal is made by filling the whole tuvar and cutting it in two,
removing the pulp and doing the necessary processing. By doing this the tuvere
lentil loses its ability to germinate.
Can
any plant grow without seeds?
Yes,
some plants grow without seeds. D. E.g., potato eye (pitted part) is planted to
grow potato plant. Similarly, plants such as rose, henna, banana, guava,
pomegranate, bordi etc. can be grown without seeds.
How
does a small seed grow into a big plant or tree?
Seeds
germinate by absorbing water from the soil. This sprout grows by getting air,
sunlight and water and finally becomes a big plant or tree.
Some
plants self-disperse their seeds over long distances. When the soybean pods are
ripe they split open and the seeds are thrown out. Have you ever heard his
voice?
No,
I have never heard his voice. But it has been read that ripe pods of soybeans
snap with a noise and the seeds are thrown away.
Have
you seen banyan, peepal or other plants growing on any wall or in a well? How
did the seed get there? Who would have gone through? find out
Yes,
I have seen banyan, peepal or other plants growing in the crevice of the wall
and in the gap of the well. Birds like pigeons, sparrows or parrots make their
nests on the wall or in a small hole in a well. These birds eat the fruits of
banyan, pipal or other plants and keep them in their nests. Their pods contain
the seeds of the fruit, and on receiving moisture or water, the seeds grow into
pods, pipals or other plants.
Think,
what happens if the seeds do not spread and fall in one place?
If
the seeds do not spread and fall in one place, all the seeds of the same tree
fall under it. The plants grown from those seeds will not get proper sun, water
and air and will not grow well. Also, if the seed falls in one place, the plant
will grow in that place, but the plant will not be found in another place.
How
are seeds spread? Write any two ways in your own words.
Seeds
are spread by wind, water, animals-birds and self-rupture of the horns.
(i)
By wind : The seeds which are light in weight are blown by wind and spread from
one place to another. D. E.g., Akado, Kanji and Shimla seeds are light and
spread by wind.
ii)
By water : Seeds floating in water are spread from one place to another by
being dragged along with the current of water. D. E.g., spread alfalfa and
fennel seeds as they float on water
How
are beans germinated?
Beans
are soaked in water overnight. in the morning
Dispersal
of seeds
Dispersal
of seeds : The beans are removed from the water, tied in a damp cloth and hung
to germinate. After that, sprouted beans are ready in a day or two.
Explain
with examples how seeds are dispersed by wind.
The
seeds of some plants are very light and have thin filaments. Such seeds fly in
the air with the wind and spread far and wide. Thus, wind helps in spreading
the seeds. D. E.g., chickpea, kanji and chickpea seeds.
Explain
with examples three factors that play a role in seed dispersal.
Factors
that play a role in dispersal of seeds are wind, water, birds and animals.
(i)
Wind : : The seeds which are light in weight are blown by wind and spread from
one place to another. D. E.g., Akado, Kanji and Shimla seeds are light and
spread by wind.
(ii)
Water : Floating seeds are spread from one place to another by being dragged
along with the current of water. D. E.g. alfalfa and fennel seeds float on
water. They spread through water.
(iii)
Birds and animals: When birds and animals eat plants, the seeds enter their
bodies. Undigested seeds fall to the ground along with bird droppings and
animal feces and spread. The seeds of Gadru and Gokhru are prickly. It sticks
to the body of animals and reaches from one place to another.
Why
do plants grow in monsoons?
Seed
dispersal takes place through various factors. Due to this, plant seeds are
spread in many places on the ground. Rainfall during monsoon provides the
necessary water for germination of seeds. So in monsoon, vegetation grows
everywhere.
If
the soil is overwatered after sowing the seeds, then why the seeds do not
sprout?
For
sprouting from seeds, it is necessary for the seeds to get adequate amount of
water. Along with this, it is equally important for the seeds to get air and
heat. After sowing the seeds in the soil, when the soil is over watered, the
seeds do not get the air and heat required for germination. So if the seeds are
overwatered after sowing, the seeds will not sprout.
State
the advantages of seed dispersal (radiation).
Advantages
of seed propagation are as follows: (1) Dispersal of plant seeds prevents them
from becoming concentrated in one place of the plant.
(2)
Dispersal of seeds causes plants to grow in different places. Therefore, they
have better access to sunlight, water and nutrients and growth is improved.
(3)
Seed dispersal allows the same plant to spread widely in new departures. Hence
the area of vegetation is year.
