Plant Life Unit Test Review

Get your fill of CHLOROPHYLL. It is a green pigment. It absorbs light energy. It is found in plant cells.

Spiny leaves prevent….? water loss

Which plant is NONVASCULAR? MOSS CONIFER FERN MONOCOT

Non-Vascular Plants remain… fairly small

Mosses and liverworts lack a vascular system. They live in… 1. sunny places 2. hot places 3. dry places 4. wet places

Vascular Plants that have specialized tissues for carrying minerals, water, or food.

Cellular Respiration: ~Carbon dioxide released ~Energy released It’s the reverse of photosynthesis.

Cellular Respiration Takes place in the mitochondria inside the cell.

Photosynthesis Produces… oxygen Energy comes from… the sun Uses ----to make food? carbon dioxide, water, and light energy Happens in the… chloroplasts

Information on Transpiration It is the loss of water vapor from leaves through pores called… STOMATA Stomata is OPEN during photosynthesis.

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

When a seed germinates… it begins to… GROW

The Vascular Plant What transports water and minerals from the roots to the rest of the plant? Xylem

Roots 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)

How do water and carbon dioxide reach a leaf cell? Plants take in carbon dioxide through their leaves (stomata) and water through their roots and stem (xylem).

Chemical Reaction to Photosynthesis: Carbon dioxide + water + sun →glucose + oxygen Stomata is open.

Chemical reaction for cellular respiration: sugar + oxygen → energy + carbon dioxide + water Or sugar + O₂ → energy + CO₂ + H₂O

What happens when the stomata is opened? 1. oxygen leaves the leaves 2. carbon dioxide enters the leaves 3. transpiration – water leaves

What are the plant’s food factories? leaves

Three parts of a seed: seed coat young plant stored food

What is the major difference between vascular and non-vascular plants? …for xylem and phloem Vascular has tubes…

The reproductive organ of the plant… flower

3 2 4 Plant Functions: 1 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 2 4 1

Plant Cuticle…purpose? The cuticle keeps the plant from drying out.
