Question

Which of the following statements are true.
a- Endothecium lies below epidermis.
b- Fusion of egg with male gamete is called apogamy.
c- Synergids are haploid
d- Point at which funicle touches the ovule is raphe.

• A. a and d only
• B. a and b only
• C. b and d only
• D. a and c only
• E. b and c only

Answer 1

The correct option is D a and c only

Anther wall comprises four layers: Epidermis, Endothecium, Middle layers and Tapetum. The epidermis is followed by a single layer of Endothecium, 2-3 middle layers and a single layer of Tapetum. Endothecium is present next to the Epidermis. Hence statement (a)is correct.

Fusion of male gamete with the egg is called syngamy and it results in the formation of a diploid zygote. Hence, statement (b) is incorrect.

Synergids are the haploid structures present in the embryo sac at the micropylar pole. Hence, statement (c) is correct.

The point at which funiculus touches the body of the ovule is called Hilum.

Hence, the statement (d) is incorrect

Since a and c statements are correct.

So, the correct answer is option D.
