What are plants?
THIS UNIT FOCUSES ON FLOWERING PLANTS
- They make their own food. Most plants make their own food using photosynthesis.They contain a green pigment called chlorophyll, which allows plants to convert energy from the sun into food. Plants store their food as starch.
- Plants are unable to move on their own, mostly being rooted to the one place. Their cell walls are rigid as they’re made of cellulose.
- There are many different types of plants.

What is a seed?
A seed is an embryonic plant enclosed in a protective outer covering known as the seed coat (testa). It is formed when the pollen and ovule of a flowering plant combine together (fertilization).

What factors (things) affect how well plants can carry out photosynthesis?
Manipulate the animation below to see what factors will increase the Oxygen bubble release rate from the water weed. Change the temperature, light intensity or the carbon dioxide and then start the timer and count how many bubbles appear per second. You can also change the colour of the light bulb by clicking the red button on the lamp.

Key Idea 3: How do flowering plants get water?
This process is called TRANSPIRATION.
Water is absorbed through the roots in a process called OSMOSIS.
It is then carried up the stem to the leaves through special cells which form a tube called the Xylem.
The water is used for several things in the plant:
1) Photosynthesis
2) For support
3) Keeping the plant cool

Key Idea 4: Why is the structure of the leaves important?
Plants cells contain a number of structures that are involved in the process of photosynthesis:
|
What are these Green things in the plant cells?
CHLOROPLAST WITH CHLOROPHYLL |
Thinking Questions:
CHLOROPLASTS: are small structures in plant cells and this is where photosynthesis happens.
CHLOROPHYLL: is a green pigment found inside the chloroplasts. It absorbs the light. Thinking Questions:
