1. Plant Characteristics

2. Why are plants important?
They provide:
Oxygen
Shelter
Medicines
Clothes
Food

3. 4 characteristics of plants
Photosynthesis
Cell Wall
Cuticle
Reproduction

4. Photosynthesis The process by which plants make food
Chloroplast in their cells captures the energy from the sunlight
6CO2 + 6H2O + Sunlight C6H12O6 + 6O2

5. Cell Wall Provides support and protection for the plant cell
Formed from Carbohydrates and Proteins
Some form a secondary cell wall that stops them from growing

6. Cuticle A waxy layer that coats most of the surfaces of plants
Keeps the plant from drying out.

7. Reproduction 2 Stages – Sporophyte and gametophyte
Sporophyte – Plants produce spores.
These spores grow into a gametophyte in suitable conditions
Gametophyte – Plants produce sex cells (sperm and egg)
The sperm must fertilize the egg
The fertilized egg then grows into a sporophyte

9. 2 Groups of plants
Nonvascular
Vascular

10. Nonvascular No specialized tissues to move water and nutrients
Depend on diffusion to move materials
Stay small due to the lack of specialized tissue
Examples are mosses, liverworts and hornworts
Mosses
Liverworts
Hornworts

11. Vascular plants
Have specialized tissue to move materials (water and nutrients)
Can grow to be very large
Divided into three groups
Seedless – examples are ferns, horsetails and club mosses
Angiosperms – also known as flowering seed plants
Gymnosperms – also known as nonflowering seed plants
2 ways the seeds of angiosperms and gymnosperms are spread: Animals and wind

12. Seedless Vascular plants
Ferns
Horsetails
Club Mosses
