Sexual Reproduction in Flowering Plants

Sexual reproduction in flowering plants involves formation of male and female gametes in the flower, followed by pollination, fertilisation, and seed formation.

Practice This Concept

Learn the concept

Student-friendly explanation

The stamen is the male reproductive part and produces pollen grains. The pistil or carpel is the female reproductive part, with stigma, style, and ovary. The ovary contains ovules, and the female gamete is present inside the ovule. After pollen reaches the stigma, the male gamete is carried towards the ovule for fertilisation.

How to write this in exams

  1. 1

    Start with the exact idea

    Sexual reproduction in flowering plants involves formation of male and female gametes in the flower, followed by pollination, fertilisation, and seed formation.

  2. 2

    Then show how to use it

    Identify male part first: anther makes pollen. Identify female part next: stigma receives pollen, style provides path, ovary contains ovules.

  3. 3

    Add one concrete example

    In a hibiscus flower, stamens produce pollen and the pistil receives pollen on the stigma before fertilisation can occur.

  4. 4

    Avoid this incomplete answer

    Writing stigma as the part that produces pollen is wrong; stigma receives pollen, while anther produces pollen.

Definition

Sexual reproduction in flowering plants involves formation of male and female gametes in the flower, followed by pollination, fertilisation, and seed formation.

Example

In a hibiscus flower, stamens produce pollen and the pistil receives pollen on the stigma before fertilisation can occur.

Rule to remember

Stamen produces pollen; pistil receives pollen; ovule contains female gamete; fertilised ovule develops into seed.

Memory hook

Anther makes pollen; stigma receives it.

Examples and method

Worked example

If a diagram label points to the swollen basal part of the pistil, identify it as ovary and state that it contains ovules.

Method to apply

Identify male part first: anther makes pollen. Identify female part next: stigma receives pollen, style provides path, ovary contains ovules.

Diagram support

Use a longitudinal section of a flower with labels: anther, filament, stigma, style, ovary, ovule, sepal, and petal.

How CBSE asks it

Questions ask for labelling, functions of flower parts, and sequence from pollination to fertilisation.

Avoid common mistakes

Common confusion

Students often write that pollen grain itself is the male gamete; pollen carries the male gamete.

Common wrong answer

Writing stigma as the part that produces pollen is wrong; stigma receives pollen, while anther produces pollen.

Exam tip

In labelled diagrams, mark stamen, anther, filament, stigma, style, ovary, and ovule clearly.

Quick check

What are the male and female reproductive parts of a flower?

The male reproductive part is the stamen, made of anther and filament, and the female reproductive part is the pistil or carpel, made of stigma, style, and ovary.

Study the sexual reproduction in flowering plants diagram carefully

Use the labelled diagram to keep sexual reproduction in flowering plants clear in short answers and revision.

What this diagram makes clear

Answer writing and exam use

1-mark answer

Sexual reproduction in flowering plants involves formation of male and female gametes in the flower, followed by pollination, fertilisation, and seed formation.

2-mark answer

Sexual reproduction in flowering plants involves formation of male and female gametes in the flower, followed by pollination, fertilisation, and seed formation. Stamen produces pollen; pistil receives pollen; ovule contains female gamete; fertilised ovule develops into seed. In a hibiscus flower, stamens produce pollen and the pistil receives pollen on the stigma before fertilisation can occur.

3-mark answer

The stamen is the male reproductive part and produces pollen grains. The pistil or carpel is the female reproductive part, with stigma, style, and ovary. The ovary contains ovules, and the female gamete is present inside the ovule. After pollen reaches the stigma, the male gamete is carried towards the ovule for fertilisation. Stamen produces pollen; pistil receives pollen; ovule contains female gamete; fertilised ovule develops into seed. If a diagram label points to the swollen basal part of the pistil, identify it as ovary and state that it contains ovules. Questions ask for labelling, functions of flower parts, and sequence from pollination to fertilisation. Writing stigma as the part that produces pollen is wrong; stigma receives pollen, while anther produces pollen.
