Question

differentiate between self pollination and cross pollination also define 1 ampere

Answer 1

In cross pollination, pollen is transferred from plant to plant by an insect or by the wind, both called pollinators. Specifically, from the pollen grains of the anther to the stigma of a flower of a different plant of the same species.

However, during self-pollination the plant's stamen shed pollen onto its own stigma during the process. The pollen grains are transferred from the anther to the stigma of the same flower.

One ampere of current represents one coulomb of electrical charge (6.24 x 1018 charge carriers) moving past a specific point in one second.
