Draw the life cycle of angiosperms ​

how can we draw that in here?

life cycle of angiosperm is comprises of two generation short lived gametophyte and a long sporophyte.

Explanation:

Following steps are involved in life cycle of angiosperm

1) Sporophyte(tree)

2) Flower (2n)

3) pollen in anther ovule in ovary

4) *sperm(n) in pollen *egg (n) in ovule

5) Fertilization (2n)

6) Zygote(2n)

7) Embryo packed in seed coat (seed)

8) Seed germinates

9) Sporophytic plant again produce

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
