What are the four different basic types of cells?
Animal
Plant
Fungal
Bateria
What are organelles and their function?
Discrete units in the cytoplasm normally surrounded by a membrane. They are responsible for specialist functions.
What is the field of view?
What you see when you look through the microscope, a bright circle.
What is a mitochondrion?
Structures found in most cells.
Function of mitochondrion?
Site of aerobic respiration.
State the parts of a mitochondrion.
Outer membrane, Inner membrane, Matrix, Cristae
Facts about mitochondrion?
. Double membrane, that surrounds a fluid filled centre ‘matrix’.
What are ribosomes?
Structures found in all cell types
Function of Ribosomes?
Site of protein photosynthesis
Where can ribosomes be?
Attached to membranes within the cytoplasm or free in the cytoplasm.
HOW TO WORK OUT SIZE !!!!
A
1. FOV = 1mm -> 1/4 = 0.25
(4)- how many things are in the circle!
2. FOV = 1.5mm -> 1.5/7 = 0.214
3. 1200(m)m -> 1.2/8 = 0.15
B
1. FOV =0.510mm ->0.510/2 ->0.255(m)m
