3 In which animal cells would Golgi apparatus be most abundant?
A ciliated epithelial cells
B goblet cells
C red blood cells
D smooth muscle cells
5 Which is a feature of all prokaryotic cells?
A absence of cell surface membrane
B division by mitosis
C presence of mitochondria
D presence of ribosomes
6 The diagram shows a cell surface membrane. The lipid bilayer has an approximate width of 8nm.
How many times has the diagram been magnified?
A 2.5 × 102 B 2.5 × 104 C 2.5 × 106 D 2.5 × 108

1 The diameter of living cells varies considerably. Typical diameters are: A prokaryote, such as Streptococcus - 750nm A eukaryotic cell, such as a white blood cell - 15µm
Given these measurements, the diameter of the white blood cell is how many times greater than the prokaryote?
A x 2 B x 20 C x 50 D x 200
2 In constructing a plan diagram of a transverse section of a dicotyledonous leaf, which feature should not be included?
A chloroplasts in the palisade mesophyll layer
B cuticle on the upper epidermis
C vascular bundles in the leaf lamina
D xylem in the vascular bundles
3 Membranous sacs containing products of metabolism are formed by the endoplasmic reticulum in cells. Where are these products used?
A inside and outside the cell
B inside lysosomes only
C inside the cell only
D outside the cell only
4 The diagram shows a graduated slide, with divisions of 0.1 mm viewed using an eyepiece graticule.
Pollen grains were grown in a sugar solution and viewed using the eyepiece graticule.
