Increasing reliance on water to bring sperm and egg together
Replacement of roots by rhizoids
Decreases in the size of the leaf

Replacement of roots by rhizoids
Explanation / Answer
The correct option is Reduction of the gametophyte phase of the life cycle.
Explaination:
Replacement of roots by rhizoids - rather primitive plants like mosses have rhizoids in place of roots
Increasing reliance on water to bring sperm and egg together- pollination is now zoophilic or entomophilic, in rare cases, it is hydrophilic.
Elimination of sperm cells or sperm nuclei - this cannot be true as most of the developed plants reproduce sexually where sperm nuclei in th pollen fuses with ovum in ovule to form a diploid zygote.
Leaves are essential for photosynthesis- a feature of autotropic modern plants.
