Notes from the test

Magnification practice of cells

Calculate the length of cell given its field of view

Lens and changes in FOv because of len change

Q26 State organelles that would be most abundant in a) muscle cells and b) pancreatic cells

Include a reason why organelles are most abundant

Muscle

• mitochondria → produces energy for movement

Pancreas

• ribosomes → Site of protein synthesis ( make proteins)

• Endoplasmic reticulum →provides a surface for protein synthesis

• Golgi apparatus →Packages and secrete proteins

Endo plasmic reticulum A)

14) Surface area B increasing the diameter of a cell increases the volume more than the surface area

16 C Types of movement of movement across the cell membrane which require energy Endo cytosis exocytosis, pinocytosis
