Question

Observe the diagrams given below:

(a) Which floral whorls are shown in Figure (1)?
) What is travelling through the pollen tube?
Explain the process shown in the (3) and (4) diagram
3
the pollen tube? ma​

Answer 1

Explanation:

1.process of transfer of pollen grains ie. transfer of pollen grains to stigma

2.pollen grains is travelling from stigma to ovary through pollen tube for fertilization

3.the process is fertilization

Answer 2

The correct answer is 1. Gynoecium, 2. Pollen grain, 3. Fertilization

Explanation:

• Gynoecium floral whorls are shown in Figure.
• Pollen grain is travelling through the pollen tube.
• The process which is shown here is Fertilization.
• Event of double fertilization and subsequent growth and development results in development of ovule into seed.
• Each seed contains a young plant embryo (developed from zygote) and nutritive tissue (the endosperm), both of which are surrounded by a protective seed coat (derived from integument).
• During development of seed from an ovule following fertilization, the ovary wall surrounding it enlarges and develops into a fruit wall while ovary makes fruit.
