What would be the number of chromosomes in the cells of the aleurone layer in a plant species with 8 chromosomes in its synergids?

1. 16

2. 24

3. 32

4. 8

Which one of the following is surrounded by a callose wall?

1. Microspore mother cell

2. Male gamete

3. Egg

4. Pollen grain

Which one of the following pairs of plant structures has a haploid number of chromosomes?
1. Megaspore mother cell and antipodal cells
2. Egg cell and antipodal cells
3. Nucellus and antipodal cells
4. Egg nucleus and secondary nucleus

The gynoecium consists of many free pistils in flowers of:

1.	Aloe	2.	Tomato
3.	Papaver	4.	Michelia

Filiform apparatus is a characteristic feature of?

1. Generative cell

2. nucellar embryo

3. aleurone cell

4. synergids

In the majority of angiosperms:

1.	egg has a filiform apparatus
2.	there are numerous antipodal cells
3.	reduction division occurs in the megaspore mother cells
4.	a small central cell is present in the embryo sac

Functional megaspore in an angiosperm develops into:

1.	Endosperm	2.	Embryo sac
3.	Embryo	4.	Ovule

Which one of the following statements regarding post-fertilization development in flowering plants is incorrect?

1.	Ovules develop into an embryo sac
2.	Ovary develops into fruit
3.	Zygote develops into an embryo
4.	Central cell develops into endosperm

A typical angiosperm embryo sac at maturity is:
1. 7-nucleate and 7-celled
2. 8-nucleate and 8-celled
3. 8-nucleate and 7-celled
4. 7-nucleate and 8-celled

Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R).

Assertion (A):	A typical unfertilised, angiosperm embryo sac at maturity is 8-nucleate and 7-celled.
Reason (R):	The egg apparatus has 2 polar nuclei.

In the light of the above statements, choose the correct from the options given below:

1.	(A) is True but (R) is False.
2.	(A) is False but (R) is True.
3.	Both (A) and (R) are True and (R) is the correct explanation of (A)
4.	Both (A) and (R) are true but (R) is not the correct explanation of (A)

How many meiotic and mitotic divisions need to occur for the development of a mature female gametophyte from the megaspore mother cell in an angiosperm plant?
1. 1 Meiosis and 3 Mitosis
2. No Meiosis and 2 Mitosis
3. 2 Meiosis and 3 Mitosis
4. 1 Meiosis and 2 Mitosis
