Table of contents: Intro. to Plants

Bellwork:1. In your own words define Photosynthesis.2. What level of the food web are plants

located?

You have 5 minutes from the bell to start class…..

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.

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 BellworkYou have 10 minutes from the bell ringing……

Define:

1. Nonvascular plant

2. Vascular plant

3. Gymnosperm

4. Angiosperm

5. Rhizoid

6. Rhizome

Cell WallsCell 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.

Study Photosynthesis notes What is needed Where it all happens

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

Do not have true stems, roots, or leaves

Rhizoid is a rootlike structure that holds non vascular plants in place and help the plant to get water and nutrients

Vascular

Do have true stems, roots, and leaves

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.

Bell Work Sept. 22, 2014

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

LeavesMain function is to make food for the plant

FlowersSepal – 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
