A bee buzzes inside a flower to drink some nectar. While there it touches the stamen. Later the bee goes to another flower and comes into contact with the flower's pistil. Which process of reproduction is this helping with?

QUESTION

A bee buzzes inside a flower to drink some nectar. While there it touches the stamen. Later the bee goes to another flower and comes into contact with the flower's pistil. Which process of reproduction is this helping with?

ANSWER

The bee is helping in pollination which is an important event in case of sexual reproduction in flowering plants.

Pollination is a part of pre-fertilisation ( gamete transfer ).

Pollination by insects ( most commonly bees ) is known as Entamophily

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
