Read the passage carefully and answer the questions.
It is important for scientists to sort animals into groups. It just as important to sort plants.
Scientists sort them by how they make another plant like themselves. This is called reproduction.
Scientists have decided to sort plants into three groups.
The first group of plants reproduces with spores. Spores are parts of the plant that break away
and travel in the wind. Each one grows into a new plant if it lands on soil that is wet and rich.
Ferns and mosses are plants that make a copy of themselves with spores.
Other plants reproduce with seeds. They are the second group. Seeds fall from the trees. They
become part of the soil and grow into new plants. Evergreens, pine trees, and fir trees are plants
that reproduce with seeds.
The third group is the plant that reproduces by flowering. Before seeds can form, the pollen inside
the flower needs to move from one part of the flower to another. The seeds form inside the
flower. Birds and insects help this by moving the pollen when they land on the flower. Some of the
flowering plants grow into fruits to eat. The seeds are hidden inside the fruit. Apples, oranges,
cherries, daisies, and roses are plants that have flowers.
1. Which group of words mean the same as the
word reproduction?
1. helps us understand
2. flowering and pollen
3. make a copy of itself
4. plants the flowers
2. Scientists have broken plants into three
different groups:
1. spores, flowers, and seeds
2. vertebrates, invertebrates, and seeds.
4. cherries, grapes, and oranges.
3. How do the plants that have spores reproduce?
1. by pushing their roots into the ground
2. by floating in the wind from place to place
3. by bees moving the pollen inside the
flowers
4. by seeds falling on the ground
4. Which type of plant group needs help from birds
or insects?
1. plants that reproduce with spores
2. plants that reproduce with flowers
3. plants that reproduce with sunlight
4. plants that reproduce with leaves

Asexual reproduction is the mode of reproduction by which new plants are produced without the
help of ______________. This mode does not require the ____________ of male and female
______________. Asexual reproduction generates new plants that are ____________ of the mother
plant. Clones are a group of cells or a new organism ______________________ identical to each
other. Asexual reproduction occurs in different kinds which includes the budding, fragmentation,
vegetative propagation, and spore formation.
Budding
In this mode of asexual reproduction, a new plant is developed from an __________________, also
called bud, in the plant body. A bud is formed due to cell ________________ at one particular
site.For example, if you keep a ____________ for long time, it is said to develop many number of
small growths, which are commonly referred as 'eyes'. Each of them can be cut and also planted.
Each of them will grow up like a clone of an ________________ plant which had produced potato.
Vegetative Propagation
Vegetative propagation is a type of reproduction in which new plants are produced from the
____________________ parts of the plants, i.e. roots, stems or buds. Vegetative propagation in
plants can occur naturally or can be artificially induced by ______________________________.
Examples of vegetative propagation:
Stems – ______________ are the stems which usually grow in horizontal above the ground. They
have the __________ where the buds are said to be formed. These ________ usually grow into new
plant.

Roots – New plants grow out of swollen, ________________ roots called ____________. Example:
Sweet Potato
Leaves – Leaves of some plants grow into a new plant when they are detached from the parent
plant. Some other plants exhibit growth of small plants, called __________________, on the edge of
their leaves. Example: ______________________.
Fragmentation
This is a mode of asexual reproduction in which a new plant grows from a fragment of the parent
plant. Each fragment develops into a ____________, fully grown individual. Some plants possess
specialized structures for ________________________ through fragmentation. This type of
reproduction happens naturally where small ________ of the plant come fall off onto soil and then
begin to ________ up into an new plant. This mode is often used by nurseries and
______________________ to produce plants quickly.
Spore Formation
Many plants and __________ form spores in their life __________. A spore is an ______________
reproductive body, surrounded by a hard ____________________ cover to withstand unfavourable
conditions such as high ______________________ and low ________________. Under favourable
conditions, the spores __________________ and grow into new plants. Plants like ________ and
ferns use this mode of reproduction.

ANSWER SHEET
Asexual reproduction is the mode of reproduction by which new plants are produced without the
help of flowers . This mode does not require the fusion of male and female gametes .
Asexual reproduction generates new plants that are clones of the mother plant. Clones are a
group of cells or a new organism genetically identical to each other. Asexual reproduction
occurs in different kinds which includes the budding, fragmentation, vegetative propagation, and
spore formation.
Budding
In this mode of asexual reproduction, a new plant is developed from an outgrowth , also called
bud, in the plant body. A bud is formed due to cell division at one particular site.For example, if
you keep a potato for long time, it is said to develop many number of small growths, which are
commonly referred as 'eyes'. Each of them can be cut and also planted. Each of them will grow up
like a clone of an original plant which had produced potato.
Vegetative Propagation
Vegetative propagation is a type of reproduction in which new plants are produced from the
vegetative parts of the plants, i.e. roots, stems or buds. Vegetative propagation in plants can
occur naturally or can be artificially induced by horticulturists .
Examples of vegetative propagation are as follows:

Stems – Runners are the stems which usually grow in horizontal above the ground. They have
the nodes where the buds are said to be formed. These buds usually grow into new plant.
Roots – New plants grow out of swollen, modified roots called tubers . Example: Sweet Potato
Leaves – Leaves of some plants grow into a new plant when they are detached from the parent
plant. Some other plants exhibit growth of small plants, called plantlets , on the edge of their
leaves. Example: Bryophyllum .
Fragmentation
This is a mode of asexual reproduction in which a new plant grows from a fragment of the parent
plant. Each fragment develops into a mature , fully grown individual. Some plants possess
specialized structures for reproduction through fragmentation. This type of reproduction
happens naturally where small part of the plant come fall off onto soil and then begin to grow
up into an new plant. This mode is often used by nurseries and greenhouses to produce plants
quickly.
Spore Formation
Many plants and algae form spores in their life cycle . A spore is an asexual reproductive
body, surrounded by a hard protective cover to withstand unfavourable conditions such as high
temperature and low humidity . Under favourable conditions, the spores germinate and

grow into new plants. Plants like moss and ferns use this mode of reproduction.

Stamen ( male reproductive part)
Pistil/Carpel ( female reproductive part)
Stamen (male reproductive part) consists of anther and filament.
The anther is a sac-like structure that produces and stores pollen .
The filament supports the anther.
Pistil (female reproductive part) comprises of three parts- stigma, style , and
ovary.
Stigma is the top most part of a flower.
The style is the long tube which connects stigma to the ovary .
The ovary contains a lot of ovules . It is the part of the plant where the seed
formation takes place.
A flower may consist of either stamen or pistil or both. Based on this, a flower can
be either unisexual or bisexual . A bisexual flower is composed of all the four parts
mentioned above, e.g. Rose , China rose. Whereas, the plants like papaya and
cucumber produce only unisexual flowers.
Pollination & Fertilization
In order to form a zygote , male gametes in pollen grains have to fuse with egg
in the ovule. This is achieved by the process called pollination . Pollination is the
process of transferring pollen grains from the anther – male part of a flower, to
the stigma – female part of a flower. Depending on the pollen landing, pollination
can be classified into two types-
Self-Pollination: A pollination where the pollen transfer takes place between the
anther and stigma of the same flower.
Cross-Pollination: A pollination where the pollen transfer takes place between the
anther and the stigma of different flowers of the same plant or different plants of
the same species.
Generally, pollination takes place with the help certain agents so called pollinators.

They include insects , water, birds , the wind, etc.
Once pollen gets transferred to stigma the male gametes from pollen grains release
and fuses with egg in the ovule to form a zygote . This process of fusion of
gametes is called fertilization . The zygote thus formed, divides and develops
into an embryo , and later into a seed . The ovary develops into a fruit .

ANSWER SHEET
The vegetative or asexual propagation is that process where a new individual plant
originates from another (parent) plant's vegetative part (stem, root or leaf) as the
former would resemble the latter in terms of their characteristics . Here we will be
discussing the natural ways of vegetative propagation:
Vegetative propagation by roots:
In this case, adventitious buds are formed by certain plant roots like poplars,
guava, murraya, shisham etc. Necessary food quantities are present in certain
tuberous adventitious roots despite having adventitious buds like sweet potato and
Dahlia. Given the proper conditions, these buds sprout well, provided they are
planted after separation . In the case of plants like shisham, new roots that grow
fast would rise from the stump cuts.
Vegetative propagation by stems:
Here, the newly formed branches are isolated by the older parts that undergo
decay . The former hence has an individual life.The decay of older parts isolates
the newly formed branches. The latter henceforth lead an independent life.
Certain corms like freesia, colocasia, crocus etc have ample food stored while
being able to produce buds that are adventitious. Bulbs like Narcissus, Garlic and
Onion are able to bear further bulbs
(i) Stem tuber:
These are found in items like Artichoke and Potato . Stem tubers are found in
Potato and Artichoke. The potato tuber is that part of an underground stem branch

that is swollen apically that could bear plenty of eyes or node. Every eye could
bear further buds. More plants are formed from the eyes with buds.
(ii) Runner:
Stems that are aerially weak like doob grass, oxalis and so on once in contact with
ground produces adventitious roots at nodes. Once the old parts of the plant decay,
the branches split to gain individual existence.
Vegetative propagation by leaf
Certain plants are able to bud adventitiously on leaves like streptocarpus, saintpaulia,
bryophyllum and so on. While the leaf is attached to the plant, the buds are in
the dormant state. But once the leaves are in contact with moist soil, new
plantlets with margins are formed. There are certain species of bryophyllum
which could form plants from intact leaves margin.
