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.
