Answer 1

Answer:

Figure 1

Lilium anther

1) generative cell

2) gc nucleus

3) gc nucleolus

4) plasma membrane

5) tube nucleus

6) intine

7)exine

Figure 2

Lilium ovule

1) integuments

2) funiculus

3) ( actually this is also 1 among antipodals and not egg)

4)antipodals

5) megasporangium

6) micropyle

7) synergid ( one cell in between synergid to be drawn, is egg)

8) polar nuclei
