Plant Features
Chloroplasts & Chlorophyll
Photosynthesis
Most plants have cell
walls and green cell parts
called chloroplasts.
Lobby
Photosynthesis is the
process in which plants use
water, carbon dioxide, and
energy from the sun to
make food.

Mosses and Liverworts
Mosses and Liverworts depend on diffusion and
osmosis to move materials from one part of the
plant to another

Chloroplasts & Chlorophyll
• Chloroplast - cell parts that contain the
green pigment chlorophyll.
• Chlorophyll - a chemical that gives
plants their green color and traps light
energy.

How are Plants Grouped
•
•
•
•
There are two groups of plants. (or divisions)
The two groups of plants are based on whether
or not they have cells that form tubes through
the length of the plant.
The tubes allow water and minerals to move up
and down in the plant and to allow food to move
from the leaves to the other parts of the plant.
The two divisions are vascular and nonvascular
plants.
Return to the Room
Vascular Plants
Vascular Plants are plants that have tubelike cells in their roots, stems and leaves
to carry food and water.
Return to the Room
Nonvascular Plants
Nonvascular plants do not have tube-like
cells in their stems and leaves.

Moss
•
•
•
•
•
Mosses have fine, soft stems that often grow upright in
mats.
Some mosses form mats but have stems that creep
along the ground.
The leaves of mosses are only one or two cells thick and
will dry out if taken from their moist environment.
Mosses can be classified by the shape of their leaves.
Mosses’ leaves grow all around the stem.
Return to the Room
Liverworts
•
•
•
•
Many liverworts don’t have roots stems, or leaves.
The body of the liverworts is often flat, slippery layer
of green cells that lies close to the ground.
Some species of liverworts have creeping stems and
small leaves.
Leaves grow in two or three flattened rows along the
stem.

Life Cycle of Moss
Return to the Room
•
Spores are released from
the spores capsule.
•
If spores land on suitable
ground they will grow into
leafy plants.
•
The plants develop male
and female organs.
•
Sperm and eggs are
formed.
•
Sperm swims to the egg
and fertilizes the egg.
•
Fertilized eggs develop
into spore capsules.
Xylem cells carry water and dissolved minerals from the roots to the
leaves.
Phloem cells carry food that is made in the leaves to all parts of the
plant.
Return to the Room
Fern Life Cycle
Spores cases are found on the
underside of the leaf. When the
spore cases open, the tiny
spores are carried by wind and
water.
If a spore lands in a moist place,
it grows into a small, flat, heartshaped plant.
The heart-shaped plant
produces sperm and egg cells.
The sperms cells swim through
the water to egg cells on the
underside of the plant Each egg
cell is fertilized by one sperm
cell.
The fertilized egg develops into
a new fern with roots, stems,
and leaves.
Return to the Room
Ferns
• A fern is a vascular plant that reproduces with spores.
• At one stage of the life cycle of a fern it does not have a
vascular system at all.
• The leaves of a fern grow a stem that is horizontal and lies
underground.
• The stem stores food and water.
• Small roots grow down from the plant and take-up water
and minerals from the soil into xylem cells.

Spruce Cone
A conifer is a plant
that produces seeds
in cones.
Pine Cone
Douglas Fir Cone
Return to the Room
A seed is the part of a plant that contains a new, young plant and
stored food.
An embryo is an organism in its earliest stages of growth.
The seed coat, or outer skin, protects the embryo, which contains all
the parts needed to form a new plant. The endosperm nourishes the
embryo until it can make its own food. The endosperm of a monocot
contains one cotyledon, and that of a dicot has two cotyledons.
Return to the Room
Life Cycle of a Pine Tree
Pine trees produce male and
female cones. The male cones
produce pollen.
Pollen are the tiny grains of seed
plants in which sperm develop.
The sperm cell fertilizes the egg
cell and the seeds containing the
embryo form between he woody
scales of the cone.
When the seeds are ripe, the
cones become dry and the woody
scales open, allowing the seeds
to fall to the ground.
When the conditions are right,
each seed grows into a young
plant.
Return to the Room
Conifers can live in many more places than most other
plants.
They can live in very wet areas, the desert, on high
mountain slopes or close to the sea.
In the United States, conifers make up the largest segment
of lumber production.
Conifers are used to make paper, and is the source for
turpentines, disnfectants, and fuel.
Conifers also provides food for animals such as birds,
insects, squirrels, rabbits and many others.
Return to the Room
A flowering plant is a vascular plant that produces seeds
inside of a flower.
The flower is the reproductive part of the plant.
Return to the Room
There are many more kinds of flowering plants in the world
than non-flowering plants.
Not all flowering plants have big, sweet-smelling flowers.
Many flowering plants have small, non-showy flowers.
Some flowering plants produce flowers only certain times of
the year.
Flowering plants are important to us because they provide
food for animals and the oxygen they give off is needed by
plant and animals for cellular respiration. (The air we
breathe.)
