Cells Flashcards
Name three differences in the structure of a plant cell and an animal cell
Plant cell has cell wall, a vacuole and chloroplasts that animal cells don’t have
Draw a plant cell (list eight structures and their functions)
Check mind map
Draw an animal cell ( list nine structures and their functions)
Check mind map
What are the seven characteristics of life?
Movement Reproduction Sensitivity Growth Respiration Excretion Nutrition
Name one method of transport of chemicals in and out of cells
Diffusion
Give an example of a unicellular organism
Bacteria
What does a ball and socket joint allow
It allows movement in any direction
What does a fixed joint allow
No movement
What does a hinge joint allow
back and forward movement
What occurs in chloroplasts
Photosynthesis
What is a organ
They are formed from tissues and when groups of tissues work together to preform a function
Name all the elements to a joint
Muscle
Cartilage
Ligaments
Tendons
What is stage 1 in the levels of organisms
Cells
What is stage 2 in the levels of organisms
Tissues - cells with similar function grouped together eg muscle
What is stage 3 in the levels of organisms
Organs - formed from tissues, when groups of tissues work together to do a function eg heart, liver, lung
What is stage 4 in the levels of organisms and give an example
Organ systems -groups of organs that perform a job eg digestive system
What is stage 5 in the levels of organisms
Organisms eg human
What is the control centre of the cell
The nucleus
What allows photosynthesis to take place
Chloroplasts
What is the cell wall
The cell wall is on the rim of the cell and it gives the cell strength (only found in plant cells)
What is the cytoplasm
Liquid in the cell where all the reactions happen
What does the vacuole contain
It contains the cell sap
What does the cell membrane do
It allows substances to pass in and out of the cell
