Question

D. Answer the following questions in short.
1. Name the various parts of a flower.
2. What is the function of calyx and corolla in a flower?
3. Define unisexual and bisexual flowers.
4. Differentiate between self-pollination and cross-pollination.​

Answer 1

Answer:

1) Petal: The parts of a flower that are often conspicuously colored.

Stamen: The pollen producing part of a flower, usually with a slender filament supporting the anther.

Anther: The part of the stamen where pollen is produced.

Pistil: The ovule producing part of a flower.

2) The outermost whorl of the flower has green, leafy structures known as sepals. The sepals, collectively called the calyx, help to protect the unopened bud. The second whorl is comprised of petals—usually, brightly colored—collectively called the corolla.

3) Unisexual and bisexual flowers are two types of flowers found in plants. ... The main difference between unisexual and bisexual flowers is that unisexual flowers contain male and female reproductive organs in separate flowers whereas bisexual flowers contain both male and female reproductive organs in the same flower.

4) Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.

1. The various parts of a flower are :-

• $\green{Petal}$
• $\green{Anther}$
• $\green{Filament}$
• $\green{Style}$
• $\green{Stigma}$
• $\green{ovary}$

2. The function of Calyx :-

$\pink{Calyx \: protect \: the \: inner \: parts \: of \: a \: flower ( mostly \: the \: bud)}$

• The function of Corolla :-

$\pink{Corolla \: assist \: in \: the \: reproductivity \: and \: aid \: in \: pollination}$

3. Unisexual Flowers :-

$\blue{The \: flowers \: in \: which \: either \: male \: or \: female \: reproductive \: organs \: are \: present}$

• Ex :- Watermelon

Bisexual Flowers :-

$\blue{The \: flowers \: in \: which \: both \: male \: and \: female \: reproductive \: organs \: are \: present}$

• Ex :- Sunflower

4. Self-pollination :-

$\orange{The \: pollen \: from \: the \: anther \: of \: same \: flower \: or \: from \: another \: flower \: on \: the \: same \: plant}$

Cross-pollination :-

$\orange{The \: pollen \: from \: the \: anther \: of \: one \: flower \: to \: stigma \: of \: another \: flower \: on \: a \: different \: individual \: of \: the \: same \: species}$
