$(a)$ Differentiate between:
$(i)$ Homologous organs and Analogous organs
$(ii)$ Pollination and Fertilisation
$(b)$ What do fossils tell us about the process of evolution?

(N/A) $(i)$ Homologous organs are those which have the same basic structural design and developmental origin but perform different functions. Analogous organs are those which have different structural origins but perform similar functions.
$(ii)$ Pollination is the process of transfer of pollen grains from the anther to the stigma of a flower. Fertilisation is the process of fusion of the male gamete with the female gamete to form a zygote.
$(b)$ Fossils provide direct evidence for evolution. They help in establishing evolutionary relationships between organisms,show the sequence of evolutionary changes over time,and act as connecting links between different groups of organisms.
