Plants
Section 6.1 Plant Classification
• Chloroplast- where photosynthesis takes
place.
• Chlorophyll- is a chemical that gives plants
their green color and traps light energy.
• Photosynthesis- is the process in which
plants use water, carbon dioxide, and
energy from the sun to make food
• 6 CO2 + 6H2O
C6H12O6 + 6O2
•
Photosynthesis separates plants from animals
• Cell wall- give plant structure (No Bones)
2 Groups of plants
1.
2.
Vascular- have tube like
cells in their roots, stems
and leaves to carry food
and water. Most
chloroplasts are in the
leaves.
Nonvascular- don’t have
tube like cells in their stems
and leaves. Grow close to
the ground in moist areas.
No Roots! Hair like cells
take up water by osmosis.
• Osmosis- is the movement of water
across a cell membrane.
6.2 Nonvascular
Plants
• Moss- is a small, nonvascular
plant that has both stems and
leaves but NO roots.
• Liverworts- no roots, stems or
leaves. Is often flat, slippery
layer of green cells that lies
close to the ground.
• DIFFERENCE between
mosses and liverworts is in the
arrangement of the
leaves…Liverworts grow in 2 or
3 flattened rows…Mosses grow
all around the stem
• Sexual Reproduction is the forming of a new
organism by the union of sperm and egg.
• Fertilization joining of egg and sperm
• Non Vascular plants reproduce by spores.
6.3 Vascular Plants
• Xylem cells that carry water and dissolved
mineral UP the roots to the leaves.
• Phloem cells that carry food made in the
leaves DOWN to all parts of the plant.
• Fern vascular plant the reproduces with
spores.
Conifers are plants that produce
seeds in cones.
• Pine cones (left) and juniper “berries” (cones, right)
• Lumber supply ¾ is from Conifers.
• Seed is the part of a plant that contains
a new young plant and stored food.
• Embryo is an organism in its earliest
stages of growth.
• Pollen are tiny grains of seed plants in
which sperm develop.
Flowering plant is a vascular
plant that produces seeds
inside a flower.
Flower is the reproductive
part of the plant. Male parts
produce pollen & female
produce eggs.
There are more flowering
plants than non-flowering
plants.
