Plant Characteristics
 Photosynthesis
is the process
plants use to
make food from
carbon dioxide
and energy from
the sun
Plant Cell Structure
Plant Characteristics
 Chlorophyll is the

captures energy from
the sun

Plant Reproduction
Fern
Plants make spores
in the sporophyte stage
Plant Reproduction
 When the spores of some plants grow, the new plants
called gametophytes
Gametophyte Stage
 The fertilized egg of a gametophyte grows into a
sporophyte
Reproduction in Plants
Stage 1
Sporophyte
Production
and
fertilization
of sex cells
Produce spores
(cloning)
Gametophytes
Stage 2
Plant Classification
 Nonvascular Plants are plants without specialized
conducting tissues
 Liverwort is an example of a nonvascular plant
Plant Classification
 Vascular Plants have tissues to
deliver water and nutrients
from one part of the plant to the
other
 Fern is an example
of a seedless vascular plant
Vascular Plants
Gymnosperm is a vascular
seed plant that does not flower
Vascular Plant
 Angiosperm is a flowering plant with seeds inside a
fruit
Parts of a Vascular plant
 Roots
 Stems
 Xylem
 Phloem
 Leaves
 Epidermis
 Spongy layer
 Palisade layer
Origin of Plants
 Same kind of
Chlorophyll
 Similar Cell Walls
 Photosynthesis
 Store energy in the form
of starch
 Two stage life cycle

Plants do photosynthesis, a
complicated process, and without
plants, we'd all be dead.”
