Question

Give reasons :
1) Cells of microsporetetrad are haploid.
2) Apple is sweet and fleshy but is a false fruit.

Answer 1

1. Microspore tetrad is formed by the meiosis of the diploid microspore mother cell so they are haploid in nature.
2. Apple is a false fruit as the fleshy part of the fruit is not formed from a ripened ovary instead from the thalamus or via some adjacent tissue such as pistil, exterior part of carpel etc.
