Question

Synergids are of which type ? (a) Diploid (b) Triploid (c) Haploid (d) Tetraploid

Answer 1

"ANSWER: (c), Haploid

Explanation:

The ovule’s embryo sac  is made up of three structures namely:

• Anti-podal cells

• Synergids

• Egg cell

• Polar nuclei

The above mentioned structures are haploid in condition. The Synergids is the structure of embryo sac which is protected by specialized “cellular thickening at the micropylar region” called as filiform apparatus. This special lining plays a unique role to guide the entry of the “pollen tubes into the Synergids”.

"

Answer 2

Synergids are haploid.  

Option (c)  

Explanation:  

• Specialized cells that remain next to the female gamete in the angiosperms, and helps in guiding the pollen to fertilize the egg are called synergids. These are two in number and haploid in nature.
• These are fundamental in stopping the growth of the pollen tube and helps in the release of the sperms.
• They create a substance known as an attractant that enables in the guidance of the sperm and also in a successful fusion.
