Plant Reproduction

Plant Reproduction
Asexual
Organism identical to parent
Sexual
Zygote
Fertilization
Egg / Sperm
Life Cycle
Gametophyte
Spores / Mitosis
Haploid
Fertilization
Sporophyte
Diploid
Some cell meiosis
Continue life cycle
Ferns
nonvascular seedless plants
Leaves called fronds
Grow from underground stem called a rhizome
Spores produced in sori
usually on the underside of fronds
Spores land and grow into a gametophyte plant called a prothallus
Sex cells form in the prothallus
Zygote starts the sporophyte stage
Reproduce asexually when rhizomes form new branches
and are separated from the main plant
Moss
Life cycle that illustrates typical repo in nonvascular seedless plants
The gametophyte stage produces sex cells
The sporophyte stage produces spores
Spores are released and land in appropriate environment, can grow into new gametophyte stage plants
Can reproduce assexually when a piece breaks off during gametophyte and settles.
Seedless Reproduction
Vascular
Has tubelike cells for transports
Nonvascular
Does NOT have tubes for transport
All plants are seedless
Do Not produce seeds
The spores of seedless plants grow into plants that produce sex cells
