1. SEEDLESS REPRODUCTION
SECTION 2
SEEDLESS REPRODUCTION

2. Importance of spores Use spores to reproduce
In sporophyte stage, sex cells are produced in spore cases
Spores are released and spread by wind, water, and animals becoming new plants
Can be from vascular or nonvascular plants

3. Nonvascular seedless plants
Mosses, liverworts and hornworts
Life cycle similar to sexual reproduction

4. Moss lifecycle
Plant looks green – (gametophyte stage). produces sex cells
Moss looks brownish – (sporophyte stage). grows little stalks
Tip of stalks contains spores for making new moss

5. Nonvascular plants and asexual reproduction
Pieces of plants (cuttings) can grow into new plants and form sex cells

6. Vascular seedless plants and fern life cycle
Most are ferns and have fronds as leaves
Grow from a rhizome which can form new plant asexually
Roots grow from rhizome
Produce spores in sori, located on underside of frond
Spores grow into a green, heart shaped prothallus that has chlorophyll
