Plant Reproduction
Many plants can reproduce by both sexual and asexual processes
Asexual Vegetative Propagation
Plant Reproduction• Angiosperms (flowering plants)
Anatomy of the Flower
Male parts of flower Female parts of flower
Two Pollination Strategies
Using Pollinators
Wind Pollination
Fruit - seed-bearing structure in flowering plants formed from the ovary after flowering
Pollination
Swelling OvariesFully mature fruit
Animal dispersal
Germination
Germination• Seeds sprout and grow using energy stored in the
seed (endosperm) to power mitosis and cell division.
Cotyledon are the first two leaves that emerge that supply energy until photosynthesis can take over with foliage leaves
Conifers (Gymnosperms) are almost exclusive wind pollinated
• Conifers have separate male and female cones on the same tree.
Mosses (Bryophytes) have two phases – a haploid and diploid stage.
• Moss sperm have to swim, so they need wet surfaces.
