Sexual Reproduction in Flowering Plants Class 7 Science Worksheet

This worksheet is for Class 7 Science, comprising the topic of Reproduction in Plants. This is a key topic in Science that also serves as the building block of plant biology in future classes. As such, students must understand this topic in detail.

As students attempt this worksheet, they will revise the following –

1. Key features of sexual reproduction

2. The disadvantages and advantages of sexual reproduction

3. Budding & zygote

1. Write some features of sexual reproduction.

The features of sexual reproduction are as follows:

• It is a process that requires a male and a female.
• Gametes are formed and fertilized.
• There is a lengthy and slow process involved.
• Different genetic and physical characteristics distinguish offspring from parents.

2. Write the disadvantages and advantages of sexual reproduction.

3. Define the following:

1. Budding
2. Zygote

1. Budding: Yeast is a single-celled creature. Buds are bulb-like extensions of yeast cells. The bud gradually splits from the parent cell and develops into a new yeast cell. This new yeast cell develops, matures, and multiplies to make additional yeast cells. A high number of yeast cells get generated in a short period of time.
2. Zygote: Seeds in embryonic plants are encased in a protective coating. After being fertilized by pollen and growing within the mother plant, a matured ovule produces seeds. The embryo is created from the zygote, while the seed coat is formed from the ovule’s integuments.

1. Fill in the blanks:

1. _________ propagation is the process of producing new individuals from the vegetative component of a parent.
2. The transport of pollen grains from the anther to the stigma of the same or another flower of the same species is known as ___________.
3. Seed dispersal takes place through __________, __________, and __________
4. The merging of male and female gametes occurs during ____________.

2. State True/False:

1. Pollination is the process of transporting seeds to distant locations.
2. The fruit is formed by successive divisions of the zygote.
3. Yeast multiply in two ways: asexually and sexually.
4. Pollen grains are a flower’s male gametes.
5. Ginger has nodes and internodes on its stem.

3. Match the following:
