ANA SAYFA


THE PLANT KINGDOM
 
 
 
*The Plant Kingdom:
 
→The plants are eukaryotic and multicellular organisms which lack mobility.
 
→They are autotrophic organisms which produce their own food via photosynthesis.
 
 
 
 
 
→They store excess glucose as starch.
 
→They have cell wall which made of cellulose.
 
 
 
 
Classification of plants:
 
→The plant kingdom are divided into two groups: non-flowering and vascular flowering plants.
 
 
 
**Non-flowering plants:
 
→These plants do not produce flowers and seeds.
 
→They produce spore as the reproductive structure.
 
→They reproduce asexually via spores and sexually by metagenesis.
 
 
→Non-flowering plants divided into two groups: non-vascular and vascular plants.
 
 
 
 
***Non-vascular plants:
 
→These plants do not have vascular tissues for the transport of materials.
 
→They do not have true roots.
 
→They have root-like structure which is called rhizoid.
 
→Their stems and leaves are simple.
 
 
→Non-vascular plants include; liverworts, hornworts and mosses.
 
 
 
 
***Vascular non-flowering plants:
 
→These plants have vascular tissues for the transport of materials.
 
→They have true roots, stems and leaves.
 
 
→Vascular non-flowering plants include; horsetails, whisk ferns and ferns.
 
 
 
 
**Vascular flowering plants:
 
→These plants produce flowers and seeds.
 
→They have vascular tissuesroots and leaves.
 
 
→Vascular flowering plants are divided into two groups: Gymnosperms and Angiosperms. 
 
 
 
 
***Gymnosperms:
 
→These plants do not have true flowers.
 
→They have flower-like structure which is called cone.
 
 
→They produce seeds that do not develop within an enclosed structure (without fruits).
 
→They are tall evergreen trees.
 
→They have woody stemstaproots and mostly needle-shaped leaves.
 
 
→Gymnosperms include; Ginkgo, Sequoia, Pine, Juniper, Cypress, Fir, Spruce...
 
 
 
 
***Angiosperms:
 
→These plants have true flowers.
 
→They produce seeds that develop inside a protective structure (with fruits).
 
 
→Angiosperms divided into two groups: monocotyledons and dicotyledons.
 
 
 
 
►Monocotyledons:
 
→They are mostly herbaceous plants.
 
 
 
 
→They have one seed-leaf, fibrous roots and leaves with parallel veins.
 
→Their leaves do not have a petiole.
 
 
→Monocotyledons include; Bulbous plants, Grains, Orchids, Bananas, Ginger, Pineapple, Palm trees...
 
 
 
 
►Dicotyledons:
 
→They are mostly woody plants.
 
 
 
 
→They have two seed-leaftaproots and leaves with network veins.
 
→Their leaves have a petiole.
 
 
→Dicotyledons include; Beans, Chickpea, Lentil, Tomatoes, Spinach, Roses, Apples, Apricots...
