A. Plant Kingdom

1) Multicellular

2) autotrophic- Ps

3) Most live on land- problems

Get water / anchor plant----->roots

Grow tall /get sun/ transport water and food-----> stems with

vascular tissue

Sperm swim to egg on land-------- >pollen

3) 2 main Types of plants

a) Mosses- Bryophytes

no real roots or stems- no good anchor- no transport tissue -low to the ground

sperm needs water to swim to egg- must live where it is moist

b) Tracheophytes- vascular plants

have roots, stems and vascular tissue

can grow tall

2 types of tracheophytes

1) Pterophytes- ferns - Seedless tracheophytes

still need water to reproduce, live in moist areas

Alt of Gen: sporophyte / gametophyte

frond / fiddleshead

2) Spermatophytes- seed plants

pollen- no water to reproduce

seeds protect offspring until conditions are good

These can live most anywhere.

Seed- coat, food, embryonic plant

There are 2 kinds of spermatophytes

a) gymnosperms- cone plants

pollen, eggs seeds produced in cones-

conifers, needles, evergreens

"naked seed"

Ginkgo- broad leaf, deciduous gymnosperm

b) angiosperms- flowering plants

pollen, egg and seeds produced in flowers

pretty flowers- attract insects drab flowers- wind pollinate

seed leaves the plant inside the fruit- seed dispersal

sweet, flying, sticking

2 kinds of flowering plants- moncots (grasses, grains,some flowers) and dicots- branching plants
