Question

assertion - if in Endosperm cell of angiosperm contains 24 chromosome the number of chromosomes in each cell of root will be 16 .

reason - as the endosperm is triploid
and root cells are diploid the chromosome number in each of roots cell will be 16.​

Answer 1

Answer:

assertion is correct and reason is also correct

Explanation:

Answer 2

Both assertion and reason are true.

• An angiosperm's endosperm cell contains 24 chromosomes. The zygote and gametes would have and chromosomes, respectively, respectively.
• An angiosperm's endosperm cell contains 24 chromosomes.
• The tissue that envelops and nourishes the embryo in seed plants is known as the endosperm.
• Endosperm is naturally triploid (3n).
• 3n=24 then
• n =8
• The root structure's individual cells each stand in for the plants' 2n diploid state.
• 2n=2×8=16
• Thus, the root cell has 16 chromosomes.
• Angiosperm seeds include endosperm, a substance that protects and feeds the developing embryo (flowering plants). In some seeds (like pea and bean seeds), the endosperm is totally absorbed at maturity, and the fleshy, food-storing cotyledons feed the developing embryo. Thus, the root cell has 16 chromosomes.

Hence, Both assertion and reason are true.
