Number 2, the pistil is the female part which produces seeds, so it needs to get the pollen from the male part
Number 3,
The 3 other answers don't make sense
For number 4,
Bats, nocturnal critters, are known particularly for pollinating fruit plants such as bananas, peaches and dates. Bats also consume large quantities of insects — helping to keeping the balance of nature in a second way.
Number 5 is right.

4 is correct
Angiosperms are seed-bearing vascular plants. Their reproductive structures are flowers in which the ovules are enclosed in an ovary.
Just look at the derivative lol Ferns reproduce via spores and have neither seeds nor flowers.
Gymnosperms are a taxonomic class that includes plants whose seeds are not enclosed in an ovule (like a pine cone). Angiosperms are a taxonomic class of plants in which the mature seed is surrounded by the ovule (think of an apple).
