Plants
What are the characteristics of all plants?
What are the two types of plant?
How do plants reproduce?
Characteristics
All plants are:
1. Autotrophs
2. Multicellular
3. Eukaryotes
Why aren’t fungi, bacteria, and plant-like protists plants?
Classification of Plants
Two main groups of plants:
1. Vascular plants
2. Nonvascular plants
Nonvascular
moss
liverwort
Nonvascular
 No developed transport system
 For water & nutrients
 No roots
 Grow low to the ground
 Absorb water and nutrients and pass from cell to
cell
 Reproduce using spores or asexual reproduction
Vascular Plants
Seedless
Ferns
Gymnosperms
Conifers
Angiosperms
Flowering Plants
Vascular Plants
 3 types:
 Seedless – reproduce using spores
 Gymnosperms – reproduce using seeds
 Angiosperms – reproduce using seeds
surrounded by flowers or fruit
 Have a transport system for water and
nutrients
Plant Life Cycle
Plant Life Cycle

Plants alternate between two stages:
1. Sporophyte (asexual reproduction) Stage:
•
•
Spores produced and released
Spores create new gametophytes
2. Gametophyte (sexual reproduction) Stage:
•
•
•
Plants release sex cells
Sex cells create zygotes (seeds)
Zygotes grow into sporophytes
Plant Reproduction

Plants can reproduce asexually:



Spores
Clones (a piece of a plant can grow into a new
plant)
Plants can reproduce sexually:



Seeds (from another plant)
Seeds (from self)
Without seeds
