You are conducting artificial hybridization on papaya and potato. Which one of them would require the step of emasculation and why? However for both you will use the process of bagging. Justify giving one reason.

If artificial hybridization is performed in maize, then which of the given steps will not be required? (a) Selection of parents (b) Emasculation (c) Bagging (d) Rebagging

Some flowers, selected for artificial hybridisation, do not require emasculation but bagging is essential for them. Give a reason.

Emasculation and bagging are the two important steps carried during artificial hybridisation to obtain superior varieties of desired plants. Explain giving reasons, in which types of flowers and at what stages are the two processes carried out.

Which one of the plant growth regulators would you use if you are asked to:

You are given two convex lenses of focal lengths 5 cm and 25 cm. Which one of these would you like to use as an objective in a telescope? Give reasons for your answer.

Which one of the plant growth regulators would you use if you are asked to quickly ripen a fruit.

Give below are the events that are observed in an artificial hybridization programme. Arrange them in the correct sequential order in which they are followed in the hybridisation programme. (a) Re-bagging (b) Selection of parents (c ) Bagging (d) Dusting the pollen on stigma (e) Emasculation (f) Collection of pollen from male parent.
