#8: Plant Kingdom

Plants are multicellular organisms, with cell wall made of cellulose. They include small organisms such as mosses, ferns and flowering plants.

At least some parts of a plant are green, thanks to pigment chlorophyll. Chlorophyll absorbs energy from sunlight for plant to make glucose, using CO₂ and H₂O from environment. This is called photosynthesis.

They are divided into 2 groups, depending on number of seed leaves (Cotyledon):

1. Monocotyledonous (Monocots) 
2. Dicotyledonous (Dicots)
