Plant Reproduction
Many plants can reproduce by both sexual and asexual processes

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.
