The plant kingdom consists of the Earth's green land plants (being green due to chlorophyll colouring), the multicellular eukaryotes of the kingdom Plantae.
It can be divided broadly into vascular and non-vascular plants. It includes mosses, ferns, flowering plants, conifers, grasses, worts and green algae. Vascular plants contain conducting tissue; this tissue has the benefit of enabling the plants to grow in a broad range of habitats, which the non-vascular plants (such as algae, fungi, mosses and liverworts) cannot do.
Classification of vascular plants places them into many groups, mostly based on the seed-bearing properties of the plants. The group divisions are known as families. The family each plant belongs to is based on the plant's flowers, fruits and other structural features.
