Plants
The Basics
• Eukaryotic
• Multicellular
• Producers
– Have chlorophyll
for photosynthesis
More Basics
• Cuticle – waxy
covering that
protects the
leaves and stems
from drying out.
• Plants have cell
walls for structure
Plant Reproduction
• Plants reproduce
with spores and
gametes
• Life cycle has 2
stages
– Sporophyte –
makes spores
– Gametophyte –
makes gametes
Mosses
Ferns and club mosses
Gymnosperms – cycads, pine, ginkoes
Angiosperms
Vascular Plants
• Vascular plants have
vascular tissue that helps
them to transport
materials through their
bodies
– Xylem – carries water
from roots to leaves
– Phloem – carries glucose
from leaves to stem/roots
Cotyledon
• Seed leaf
• Used for
germination
– Provides food for
germination
Plant reproduction
• Angiosperms carryout sexual
reproduction using flowers
• Sepals – protect the immature bud
• Flowers – vary in shape and color,
attract insects for pollination
– Anther – male reproductive parts,
makes the pollen
– Pistil – female reproductive parts, tip is
called the stigma
Pollination
• Occurs when pollen grains are
transferred from anthers to stigma
• After pollination occurs, a seed
develops and the ovary develops
a fruit around it
• Once conditions are good, a seed
will germinate and grow into a
new plant
