Frequently Asked Questions
What is the difference between pollination and fertilization?
Pollination is the transfer of pollen from anther to stigma (mechanical process), while fertilization is the fusion of male and female gametes to form a zygote (biological process).
How do plants like strawberries and potatoes reproduce without seeds?
They use vegetative propagation through runners (strawberries) and tubers (potatoes). These asexual methods produce genetically identical plants clones of the parent.
