Short answer

1. Reproduction is the biological process by which new individual organisms – "offspring" – are produced from their "parents".
2. Advantages of vegetative propagation

• Quicker and more certain.
• Produces identical quality as the parent.
• Plants that do not have viable seed, can be reproduced.
• Flowers produced are of superior quality.
• Desirable character of fruit can be maintained.

3. Budding is the asexual mode of reproduction. In

budding, a genetically identical new organism

grows attached to the body of parent Hydra and

separates later on.

4. A unisexual flower is defined as a flower that possesses either stamens or carpels. They do not have both stamens and carpels. For example, papaya, coconut flowers etc. Bisexual flowers are those flowers which possess both stamens and carpels.

5. Sexual reproduction in flowering plants involves the production of male and female gametes, the transfer of the male gametes to the female ovules in a process called pollination.
