Question

Mention the role of different parts of a flower. CLASS 10 question. pls tell answer for 3 marks

Answer 1

Answer:

• Petals: This is a bright-coloured part that attracts bees, insects, and birds. Colour of petals varies from plant to plant; some are bright while some are pale coloured. Thus, petals help us to differentiate one flower from another.
• Sepals: Sepal is the green-coloured part beneath the petals to protect rising buds. Some flowers have fused petals-sepals while a few have separated petals-sepals.
• Stamen: This is the male reproductive organ and is also known as Androecium. It consists of two parts namely: anther and filaments.
• The anther is a yellowish, sac-like structure, involved in producing and storing the pollens.
• The filament is a slender, threadlike object, which functions by supporting the anther.
• Pistil: This is the innermost part and the female reproductive organ of a flower which comprises three parts -stigma, style and ovary. This is collectively known as the pistil.
• Stigma: It is the topmost part or receptive tip of carpels in the gynoecium of a flower.
• Style: It is the long tube-like slender stalk that connects stigma and the ovary.
• Ovary: It is the ductless reproductive gland that holds a lot of ovules. It is the part of the plant where the seed formation takes place.

Answer 2

Answer:

Parts of a Flower

The different parts of a flower are mentioned below:

Vegetative Parts of a Flower

The vegetative part of a flower consists of the following:

• Petals: This is a bright-coloured part that attracts bees, insects, and birds. Colour of petals varies from plant to plant; some are bright while some are pale coloured. Thus, petals help us to differentiate one flower from another.
• Sepals: Sepal is the green-coloured part beneath the petals to protect rising buds. Some flowers have fused petals-sepals while a few have separated petals-sepals.

Reproductive Parts of a Flower

Flowers contain the plant’s reproductive structures

In different plants, the number of petals, sepals, stamens and pistils can vary. The presence of these parts differentiates the flower into complete or incomplete. Apart from these parts, a flower includes reproductive parts – stamen and pistil. A flower may have only female parts, only male parts, or both.

The reproductive parts of a flower consist of the following:

• Stamen: This is the male reproductive organ and is also known as Androecium. It consists of two parts namely: anther and filaments.

1. The anther is a yellowish, sac-like structure, involved in producing and storing the pollens.
2. The filament is a slender, threadlike object, which functions by supporting the anther.

• Pistil: This is the innermost part and the female reproductive organ of a flower which comprises three parts -stigma, style and ovary. This is collectively known as the pistil.

1. Stigma: It is the topmost part or receptive tip of carpels in the gynoecium of a flower.
2. Style: It is the long tube-like slender stalk that connects stigma and the ovary.
3. Ovary: It is the ductless reproductive gland that holds a lot of ovules. It is the part of the plant where the seed formation takes place.
