Transcript Classification of Plants

Plant Classification &
Anatomy
Plants can be classified into 2 main groups:
 Non-Vascular Plants
 mosses = no vascular systems
 Vascular Plants
 Gymnosperms = complex vascular
system + bare seed (cone)
 Angiosperm = complex vascular
system + enclosed seed within a
flower

Vascular Plants: Angiosperms
Made of 4 organs:
1. Leaf – Photosynthesis, produce glucose
2. Stem – Supports flower for easy pollination,
supports leaf to capture sun.
3. Root – Absorbs water and minerals from soil
Anchors plant
4. Flower – For sexual reproduction
Male gamete: Pollen
Female gamete: Egg in ovary
Two types of Vascular Plants ~ P. 531
1. Monocot
- Seed: eg. Corn, 1
cotyledon (seed leaf)
- Stem: Vascular
bundles scattered in
pith
- Flower: Multiples of 3
(trillium)
- Leaf: Veins run parallel
through leaf
-Roots: Fibrous

2. Dicot
- Seed: eg. Peanut, 2
cotyledons
- Stem: Vascular
bundles in a ring
- Flower: Multiples of 4 or 5
- Leaf: Veins are “net” like
- Roots: tap root
Roots
 Two types:
1. Tap root
2. Fibrous

Stems
 Herbaceous – green
& soft, don’t survive
the winter
 Woody – tough &
hard, survive winter

Parts of the flower:
Male reproductive part = stamen
which are made up of…
 filament - stalk
style
 anther – produces pollen
grains
Female reproductive part = Pistil
which is made up of…
 style – stalk
 stigma – sticky surface at
tip of style
 ovary – organ that
contain the egg
Pollination
1. Pollen grain moves from anther to pistil.
2. The grain forms a tube and pollen travels
down it to the egg in the ovary. There is
a different pollen grain for each egg.
3. Each fertilized egg becomes a seed.
4. The ovary wall becomes the flesh of the
fruit.
