Grade 7 - Classification of Plants


Classification of Plants
Plants can be did into flowering plants(plants that bear flowers)and non-flowering plants ( plants that do not bear flowers)

Flowering and  Non Flowering Plants


Flowering plants - form seeds inside fruits that develop from the flowers.




Flowering plants can be divided into monocotyledons ( with one cotyledon or seed leaf in the seed) and dicotyledon ( with two cotyledon or two seed leaves).

Monocotyledons:(one seed)
MONO- one
COTYLEDON- seed

-flowers often small and pale, eg. Grass, corn

-mainly small with thin trunks, eg. Coconut tree

-leaves long and thin with parallel veins, eg. Grass

-Seeds with one dicotyledon eg. Corn

-Root has many small roots, eg. Onion







These are examples of Monocotyledonous plants





Dicotyledon  Plants
DI- two
COTYLEDON- seed

- flowers often large and colorful, eg. Rose, flame tree

- small, medium or large with very wide trunks, eg. Mahoe

-leaves oval, hand shaped, or with little leaflets with with veins like a net eg. Hibiscus, sweet potato

-seeds with two cotyledons, eg. Bean root has one main root, eg. Carrot






Examples of dicotyledonous plants









Non-Flowering Plants

You are probably not aware that non-flowering plants exist, but you may have seen some while exploring the environment or while having fun on the beach.

1. Algae: simple plants without roots, stems or leaves that live in water, mainly on the shore, eg. seaweeds










2. Mosses: soft green cushions with small leaves, mainly found in damp places and reproduce by spores, eg. Moss








3. Ferns: have proper roots and stems and leaf- like fronds that unfurl, spores are found under the fronds, eg. ferns









4. Conifers: large plants (trees) with trunks and seeds formed inside cones. Have thin, needle-like leaves, pine.
