- Do not eat drink or taste anything in the lab
- Long hair must be tried up
- Wear eye protection when told
- Stow bags and stools under desk
- Do nothing use any equipment unless told
What is a hypothesis
Is an initial idea to explain their observations
What must a hypothesis be
Testable
What is the function of a cell membrane
Holds the cell together it controls what can enter and leave the cell
What is the function of cytoplasm
Is a watery jelly like fluid in which the other structures are suspended
What is the chromosomes function
Contains protein and DNA
What is the function of Nucleus
Nucleus controls cell activities
What is the function of small vacuole
Small vacuole used for storage of food and water
What is the function of mitochondria
Carries out respiration
What is the function of chloroplasts
Contains a chemical called chlorophyll
What is chlorophyll
Which allows plants to complete photosynthesis
What is photosynthesis
Photosynthesis is the way that plant cells use the suns energy to produce glucose
What is the function of the cell wall
Gives the plan cell support and structure
What is the function of large vacuole
Stores water sugar and waste
Label the plant and animal cells
Done
What is the function of red blood cells
Carry oxygen around the body
What is the function of nerve cells
Carry electrical messages and pass these messages to other cells this enables us to think, feel, move, taste, see and hear
What makes up tissue
A group of cells working together
What makes up organs
Tissues working together
What makes up systems
Organs working together
What makes up organisms
Systems working together
What is the word equation for photosynthesis
Carbon dioxide + water light energy
—————>
Chlorophyll
Glucose + Water
Word equation for aerobic respiration
Glucose + Oxygen ———> Carbon dioxide + water + energy
How is glucose transported around the plant
In phloem cells
