How are plants classified?

2. All Plants share…
Nearly all plants are autotrophs, meaning they produce their own food.
With the exception of some green algae, all plants are multicellular
All plants have cells surrounded by cell walls

3. Autotrophs
Photosynthesis – process by which the plant takes in sunlight, water, and carbon dioxide and makes sugars and oxygen

4. Plant organization
Levels of organization in a typical plant include cells, tissues, organs, organ systems, and organism
The two main organ systems in plants are the root system and shoot system

5. Flowers The flower is the reproductive organ of some kinds of plants
These can be made of male or female parts, or both

6. Leaf Plant organ that makes food for the plant
Except for a thin layer of tissue that covers the leaf, most cells in the leaf contain chloroplasts

7. Stem Organ that holds leaves up so they can absorb sunlight
Most of the stem is made of vascular tissue which are tube-like structures inside a plant

8. Vascular tissue Two types of vascular tissue
Xylem – water and minerals are moved through xylem
Phloem – food moves through phloem tissue

9. Root Plant organ that anchors the organism to the ground
Contains tissues that absorb water and minerals

10. Retaining Water
When there is more water in a plant, than in the surrounding air, water leaves the plant and enters the air
An adaptation that allows a plant to reduce water loss is a waxy layer called the cuticle

11. How are plants classified?
Plants are classified according to their structures and how they reproduce
Vascular and nonvascular plants

12. reproduction
Vascular plants are further classified by how they reproduce
Seedless vascular plants, and vascular plants that form seeds
One group of seed plants produces flowers and the other does not

13. gymnosperms
Gymnosperms are vascular plants that use seeds to reproduce but do not form flowers – most use cones

14. Angiosperms
Angiosperms are vascular plants that reproduce by forming flowers that produce seeds
Some flowers are large like the bluebonnet and others are very small like those of an oak tree – OR CEDAR
