Question

Triploid tissue is

• A. Endosperm in Maize/ Wheat/ Lily
• B. Leaf in Onion/ Bryophyllum/ Pinus
• C. Root in Onion/ Radish/ Carrot
• D. Fern prothallus

Answer 1

The correct option is A Endosperm in Maize/ Wheat/ Lily

In angiosperms, the endosperm is formed from triple fusion in which male gamete fuses with a diploid secondary nucleus resulting in the formation of a triploid primary endosperm mother cell which then forms the endosperm. Hence endosperm is a triploid tissue. Whereas leaf is a diploid tissue, the root is haploid and fern prothallus is also haploid as it develops from a spore produced by meiosis.

So, the correct answer is A.
