According to engler and prantl system the monocots are placed before dicots. From various groups of gymnosperms, Angiosperms are evolved monocots and then dicots. From angiosperms $1^{\text {st }}$ evolved monocots and then dicots. It means that dicots are advanced whereas monocots are primitive.

Figs belong to
1 critical link species, as they form connecting link between trees and herbs
2 critical link species, as they establish essential link in the absorbance of nutrients from soil and organic residues.
3 keystone species, as they produce large quantity of fruits; and their protection leads to conservation of animals dependent on them
4 keystone species, as they have high degree of animal-dependent pollination
Explanation:
Figs represent keystone species because they produce large quantity of fruits; and their protection leads to conservation of animals dependent on them.

Vegetative fertilization is also called
1 triple fusion
2 true fertilization
3 syngamy
4 generative fertilization
Explanation:
Vegetative fertilization is also called triple fusion. It involves the fusion of second male gamete with two polar nuclei or their fusion product. As a consequence, a triploid primary endosperm nucleus develops, splits and produces triploid endosperm.

During the process of sexual reproduction in flowering plants, double fertilization involves
1 fertilization of egg cell by two male gametes
2 fertilization of egg cell and a central cell by two male gametes brought by same pollen tube
3 fertilization of egg cell and a central cell by two male gametes brought by different-pollen tube
4 fertilization of two egg cells by two male gametes brought by same pollen tube
Explanation:
During the process of sexual reproduction in flowering plants, double fertilization involves fertilization of egg cell and a central cell by two male gametes brought by same pollen tube. Triploid endosperm nuclei are created when two polar nuclei fuse with haploid sperm.
