What a flower with both stamens and pistil is called?

The flowers having both androecium or stamens and pistil or gynoecium is called as bisexual flowers. Both male and female haploid gametes are produced in these flowers. Example: Hibiscus, rose, etc.

How is the process of pollination different from fertilisation? Clarify.

Features Pollination Fertilization Definition It involves the transfer of pollen grains from the anther to the stigma of a flower. Fertilization involves the fusion of male gametes and female gametes. Features Pollination Fertilization Followed by and involvement of pollinators Pollination is followed by the fertilization and involves the pollinators such as wind, insects, water, etc. Fertilization is followed by seed formation in plants and do not involve any external pollinators like wind, water, insects, etc.

What do you understand by Regeneration and Budding?

Both are the types of asexual reproduction. Regeneration is the ability to grow parts lost in accident or injury because they have totipotent cells. Example: In extreme forms of regeneration as found in Hydra and Planaria . The animal can be cut into many pieces with each piece growing to form the complete animal. The reproductive process in which some multicellular and unicellular organisms like yeast develop one or more buds (outgrowth) from any portion of their body surface is known as budding. When these outgrowths increase in size they ultimately detach from their parent cell and grow into new individuals.

Write the name of two plants raised by vegetative propagation.

Vegetative propagation is a means of asexual reproduction in which, the new plants can be grown from the vegetative parts, such as roots, stem, and leaves. Plants such as banana, rose, etc., have lost their capacity to produce viable seeds, hence the process of vegetative propagation is followed.

What do you understand by unisexual and bisexual flower? Give one example of each.

Characteristics Unisexual flowers Bisexual flowers Definition The flowers which either contain the stamen or the pistil but not both are called unisexual flowers. Example: Papaya. The flowers which have both stamen and pistil are called bisexual flowers. Example: Hibiscus . Characteristics Unisexual flowers Bisexual flowers Pollination Unisexual flowers undergo cross-pollination, which is facilitated by different pollinating agents such as wind, water, and insects. Bisexual flowers undergo self-pollination, which is not facilitated by different pollinating agents.

What do you understand by self-pollination and cross-pollination?

Features Self-pollination Cross-pollination Definition The process of transfer of pollen grains from the anther of a flower to the stigma of the same flower is called self-pollination. The transfer of pollen grains from the anther of a flower to the stigma of another flower of the same or different species is called cross-pollination.

What is the basic event in reproduction?

The process in which the parent organism give birth to young ones is called reproduction. During which, the genetic characteristics are passed on from the parents to the offspring in the form of DNA. DNA is located in the nucleus of the cell. Hence, the two basic event in reproduction are DNA copying and cell division.
