Bellwork
Photosynthesis – plants use
light energy from the sun to
make their own food from the
carbon dioxide they get from
the air and water the absorb
from the soil.
Plants are the base level of the
food web and energy
pyramid. They are known as
producers, because they make
their own food.

Draw the diagram to the right
into your compbook.
There are crayons and colored
pencils at each table group so
that you may add color.
You have 5 minutes……
Characteristics all plants
share….
 Photosynthesis – they all make their own food
 Cuticle – a waxy layer that coats most of the
surfaces of plants that are exposed to air and keeps
the plant from drying out.
 Cell walls – all plant cells are surrounded by a cell
wall
 Reproduction – sporophyte stage and gametophyte
stage
 Photosynthesis

Sept. 12th Bellwork
You have 10 minutes from the bell ringing……
Define:
1. Nonvascular plant
2. Vascular plant
3. Gymnosperm
4. Angiosperm
5. Rhizoid
6. Rhizome
Cell Walls
Cell wall – surrounds the cell
membrane. The cell wall
supports and protects the plant
cell.
Cell membrane – surrounds a
plant cell and lies beneath the
cell wall.
Vacuole – stores water, helps
support the cell, and plays a
role in many other cell
functions.
Chloroplasts – contain
chlorophyll that captures
energy from the sun.

Quiz over Photosynthesis in 10 minutes……
Photosynthesis Quiz
1. What gas does a plant use from the air around it to
make its own food?
2. Where does a plant get the energy that it needs for
photosynthesis?
3. What liquid is necessary for photosynthesis?
4. Where in the plant cell does photosynthesis occur?
5. What is the green pigment (located in the
chloroplasts) that captures energy from the sun
called?
Plant Classification
Seedless plants
Nonvascular
Vascular
 Do not have true stems,
roots, or leaves
 Do have true stems, roots,
and leaves
 Rhizoid is a rootlike
structure that holds non
vascular plants in place
and help the plant to get
water and nutrients
 Rhizome – underground
stem from which new
leaves and roots grow
Answer the following
questions
 How are nonvascular plants important to the
environment?
 How are seedless vascular plants important to the
environment?

Vascular seed plants
Gymnosperm
 Trees & Shrubs that do not
have flowers or fruit
Angiosperm
 Have flowers and seeds
that are protected by fruit
Seed plants reproduce with the help of animals and the
wind.

 Describe two advantages that seed plants have over
seedless plants.
 How are flowering plants important to humans?
Hint: answers are in sect. 3 of Ch. 6
Structures of
seed plants
Plants have roots and shoots.
Vascular system between
these two are connected.
Xylem is vascular tissue that
transports water and minerals
through the plant from the
roots to the shoots.
Phloem is vascular tissue that
transports food molecules to
all parts of a plant.
Both are found in ALL parts
of vascular plants.
Roots
 Functions:
 supply plants with water
and minerals
 hold plants in place
 store surplus food
Stems- connects a
plant’s roots to its leaves
and flowers
• Support the plant body
• Transport materials
between root system and
the shoot system
• Some store materials
Herbaceous stems-are soft,
thin, and flexible
Woody stems-rigid and
made of wood and bark
Leaves
Main function is to make food for the plant
Sepal – one of the outermost
rings of modified leaves that
protect the flower bud
Petal – one of the ring or rings
of the usually brightly
colored, leaf-shaped parts of a
flower
Stamen – the male
reproductive structure of a
flower that produces pollen
and consists of an anther at
the tip of a filament
Pistil – the female
reproductive part of a flower
that produces seeds and
consists of an ovary, style,
and stigma
Ovary – the lower part of a
pistil that produces eggs in
ovules
Flowers
