Plant Division

The four major groups of plants are mosses, ferns, conifers and flowering plants.

Mosses are land plants but they do not have seeds like flower plants. Mosses reproduce with spores and lack vessels which restricts them to be a smaller size. They are found in moist environments.

Ferns are made up of vascular systems. Ferns do not have flowers and reproduce with spores, each spore grows into a new plant called gametophyte.The gametophyte produces gametes (eggs and sperm), which unite to produce the fern plant.

Conifers produce seeds not spores. Conifers produce pollen cones, in which develop microsporangia, which undergo meiosis, producing pollen grains, which are immature male gametophytes. The pollen is blown by the wind onto female cones.

Flowering Plants also known as angiosperms. The flower attracts many animals that help in pollination. The seed develops in a ovary which turns into a fruit. Many animals will eat the fruit and the seed with be passed along through the digestive system, unharmed and then will be deposited into the ground.
