Reproduction in flowering plants
A- sexual reproduction

parent
↳ clones of parent
→
No gametes
→
Mitosis occurs
Advantages : .
large # of offspring produced quickly .
Energy expenditure low
'
=
Offspring adapt easily to parents environment

.
Disadvantages :
-
No genetic variation : difficult to adapt to
changed environmental conditions .
Disease out
