WHERE DID PLANTS COME FROM?

• Millions of years ago, tiny specks of protoplasm(name for the living material found in both plants and animals) appeared on the earth.


• They developed a kind of green colouring matter known as chlorophyll that enabled them to make food from substances in air, water and soil.


• The early green plants had only one cell, but they later formed groups of cells.


• Spores are little dusklike cells something like seeds, but containing no stored food in them as seeds do.


• Types of plants with seeds:
  1.Those with naked seeds
  2.Those with protected seeds


• Types of plants:
  1.Algae – descendents of plants that stay in water.
  2.Fungi – non-green plants that develop food without the use of chlorophyll.
  3.Mosses & Ferns – evolved from algae that developed little leaves with an outer skin covering, as protection against drying.
