Plant Classification

Plant Classification Anatomy
2
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

5
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

6
Two types of Vascular Plants P. 531

• 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

7
Roots

• Two types
• 1. Tap root
• 2. Fibrous
• Sketch and label diagram on page 533!

Stems

• Herbaceous green soft, dont survive the
  winter
• Woody tough hard, survive winter

Parts of the flower

• Male reproductive part stamen which are made
  up of
• filament - stalk
• 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

style

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.
