Cell Structure Flashcards
What is the function of mitochondria?
Site of respiration to transfer energy for the cell
What is the function of chloroplast?
Contain chlorophyll to absorb light energy for photosynthesis
How are electron microscopes different to light microscopes?
Electron microscopes cannot view living samples, are much more expensive and have higher magnification and resolution
What is the function of the red blood cell?
To transfer oxygen around the body
Give 3 adaptations of the red blood cell
No nucleus, red pigment called haemoglobin and has a bi concave shape
Give two adaptations of the nerve cell
Branched endings, myelin sheath insulates the axon
Give two adaptations of a sperm cell
Tail, contains lots of mitochondria
What is the function of a palisade cell?
Carried out photosynthesis in the leaf
Give two adaptations of the palisade cell
Lots of chloroplasts, located at the top surface of the leaf
What is the function of a root hair cell?
Absorbs minerals and water from the soil
Give two adaptations of the root hair cell
Long projection, lots of mitochondria
What does denatured mean
Shape of an enzymes active site changes due to high temp or extreme PH this means the substrate cannot bind to it
