In a 50 gm living tissue, what would be the amount of water
15- 25 gm
25 - 30 gm
35- 45 gm
70- 90 gm
C.
35- 45 gm
Water is the most abundant chemical compound in living organism. In a cell, water occupies 70-90% of the cellular mass. So, in 50 gm of living tissue 35-45 gm of water would be present.
Cleistogamy is leading over anthesis because
pollination agent is not required
it assures heterozygosity
it favours insect pollination
it allows xenogamy
