Answer:
New plants are obtained from seeds: Sexual Reproduction.
Answer:
produce its kind is a
characteristic of all living
organisms. You have already
learnt this in Class VI. The production
of new individuals from their parents is
known as reproduction. But, how do
plants reproduce? There are different
modes of reproduction in plants which
we shall learn in this chapter.
12.1 MODES OF REPRODUCTION
In Class VI you learnt about different
parts of a flowering plant. Try to list the
various parts of a plant and write the
functions of each. Most plants have
roots, stems and leaves. These are called
the vegetative parts of a plant. After a
certain period of growth, most plants
bear flowers. You may have seen the
mango trees flowering in spring. It is
these flowers that give rise to juicy
mango fruit we enjoy in summer. We eat
the fruits and usually discard the seeds.
Seeds germinate and form new plants.
So, what is the function of flowers in
plants? Flowers perform the function of
reproduction in plants. Flowers are the
reproductive parts.
There are several ways by which
plants produce their offspring. These are
categorised into two types: (i) asexual,
and (ii) sexual reproduction. In asexual
reproduction plants can give rise to new
plants without seeds, whereas in sexual
Asexual reproduction
In asexual reproduction new plants are
obtained without production of seeds.
Vegetative propagation
It is a type of asexual reproduction in
which new plants are produced from
roots, stems, leaves and buds. Since
reproduction is through the vegetative
parts of the plant, it is known as
vegetative propagation.
Activity 12.1
Cut a branch of rose or champa with a
node. This piece of branch is termed a
cutting. Bury the cutting in the soil. A
node is a part of the stem/branch at
which a leaf arises (Fig. 12.1). Water the
cutting every day and observe its
growth. Observe and record the number
of days taken for roots to come out and
