It is a green pigment. It absorbs light energy. It is found in plant cells.

Get your fill of CHLOROPHYLL.

Spiny leaves prevent….?

water loss

Which plant is NONVASCULAR?

CONIFER MOSS

FERNMONOCOT

Non-Vascular Plants remain…

fairly small

1. sunny places

2. hot places

3. dry places

4. wet places

Mosses and liverworts lack a vascular system. They live in…

Cellular Respiration:

~Carbon dioxide released

~Energy released

It’s the reverse of photosynthesis.

Takes place in the mitochondria inside the cell.

Cellular Respiration

Photosynthesis1. Produces… oxygen

2. Energy comes from… the sun

3. Uses ----to make food? carbon dioxide, water, and light

energy

4. Happens in the… chloroplasts

Information on Transpiration

Stomata is OPEN during photosynthesis.

It is the loss of water vapor from leaves through pores called…

◦STOMATA

Question: What takes place in the chloroplast inside the plant cell?

photosynthesis

it begins to…

When a seed germinates…

GROW

What transports water and minerals from the roots to the rest of the plant?

The Vascular Plant

Xylem

1. They supply plants with water and minerals from the soil.

2. They support and anchor the plant.

3. They store food as sugar or starch. (examples: carrot, potato)

Roots

Carbon dioxide + water + sun →glucose + oxygen

Chemical Reaction to Photosynthesis:

Stomata is open.

sugar + oxygen → energy + carbon dioxide + water

Or

sugar + O₂ → energy + CO₂ + H₂O

Chemical reaction for cellular respiration:

1. oxygen leaves the leaves 2. carbon dioxide enters the leaves 3. transpiration

What happens when the stomata is opened?

What are the plant’s food factories?

leaves

Three parts of a seed:

seed coat

young plant

stored food

Vascular has tubes…

…for xylem and phloem

What is the major difference between vascular and non-vascular plants?

The reproductive organ of the plant…

flower

What enters the plant at #1? water

What leaves the plant at #2? oxygen

What enters the plant at #3? carbon dioxide

What is made in #4? sugar

Plant Cuticle…purpose? The cuticle keeps the

plant from drying out.
