Mosses:
We found the mosses around our school. Mosses need to live in moist areas because they need water for reproduction and to get nutrients. Mosses grow close to the ground because they don't have vascular tissues,so they get water throughout the plant by using diffusion. They can also grow on rocks because since mosses need moist environments to live in the rocks found on those areas are suitable for mosses to grow on.

Ferns:
Ferns need to live in moist environments because they have vascular tissues that help them transport water throughout the plant and to cells. They also need water to reproduce.The structure of plants and ferns are different because ferns are vascular and mosses are non-vascular. The vascular structure allows ferns to grow taller. Also ferns have a horizontal root-like structure which is called rhizomes. Ferns need to grow in the soil to get nutrients and minerals.

Gymnosperms:
Gymnosperms can live in varied environments because of they do not require water for reproduction.Instead they use pollen for reproduction.Also gymnosperms produce seeds.The difference between pollination and fertilization is that pollination is when pollen is transfered to the stigma of a plant and fertilization is when an egg and sperm join together.

Angiosperms:
Angiosperms are well adapted to life on land because they can depend on insects to transfer pollen or they can also depend on the wind to carry the pollen through the air and transfer it to another plant.The roots help them absorb water.The purpose of the fruit is to protect the flower and make sure the seed gets dispersed.
