Cells And Simple Cell Transport Flashcards
What does the nucleus do?
controls that activities of the cell
What are the parts in most animal cells?
Cell wall
Chloroplast
A permeable vacuole
What are the parts in most bacterial cells?
Cytoplasm
Membrane surrounded by a cell wall
The genes are not in a distinct nucleus
What are the parts in most yeast cells?
Nucleus
Cytoplasm
Membrane surrounded by a cell wall
What is yeast?
A single-celled organism
What does cytoplasm do?
Most chemical reaction takes place
What does a cell membrane do?
It controls the passage of substances into and out of the cell
What does mitochondria do?
It is where most energy is released in respiration
What does ribosomes do?
It is where protein synthesis takes place
What does cell wall do?
It is made of cellulose which strengthens the cell
What does chloroplasts do?
They absorb light energy to make food
What does a permanent vacuole do?
It is filled with cell sap
What may cells be specialised to do?
To carry out a particular function
How do dissolved substances move into and out of cells?
By diffusion
What is diffusion?
It is the spreading of the particles of gas, or of any substance in solution, resulting in a net movement from region wheee they are of higher concentration to a region with a lower concentration. The greater the difference in concentration, the fast the rate of diffusion
