Resumo de Recurso
Cells
Eukaryotes
Most animal and plant cells are eukaryotic
Have a nucleus and other membrane-bound organelles
Plant and animal cells
Cell Membrane
Controls what comes in and out of the cell
Nucleus
Controls cell function and contains genetic information
Mitochondria
Perform cellular respiration
Ribosomes
Perform protein synthesis
Cytoplasm
Site of most chemical processes, controlled by enzymes
Just plant cells
Cell wall
Adds additional support and structure to the cell
Vacuole
Contains cell sap - dissolved sugars and salts
Chloroplasts
Perform photosynthesis
Prokaryotes
Have no nucleus
Mostly bacteria
Flagella
Allow the cell to move
Plasmids
Smaller loops of DNA
Chromosome / DNA ring
Larger loops of DNA
Magnification
he number of times larger the image is than the real size of the object
Magnification = Image height / Object height
Resolution
Smallest distance between two objects that can still be distinguished as different things
Specialisation
Cells specialise becuase they all have different functions and need to perform them as efficiently as possible
The cell adapts to conform to the active DNA
Stem Cell
An undifferentiated cell that can specialise into other cell types, or produce more stem cells
Can't always specialise beyond pre-birth growth
Become only in bone marrow, making a few cells e.g. blood cells
Microscopes
Light
Light is shone through the specimen
x2000 at max
Up to 200nm
Only large, nucleus, chloroplasts
Alive and needs little preparation
Electron
Electrons are fired at the specimen
x50,000,000 at max
0.1nm
Ribosomes, and within structures such as mitochondria
Must be dead, and requires lots of preparation
