A student made notes describing photomicrographs of four cells.
cell 1 Grey cytoplasm at edge of cell contains many black lines and spots. Large white area in centre of cell.
cell 2 Grey cytoplasm contains many black lines and spots which fill the entire cell.
cell 3 Pale blue cytoplasm surrounds a single dark blue spot.
cell 4 Many green structures are enclosed within a rectangular shape with visible boundaries.

Which table identifies the type of cell and the type of microscope used to take each photograph?

Capillaries are known as exchange vessels. Substances are exchanged between blood and tissue fluid as the blood flows through the capillaries.

Fig. 1.1 is an electron micrograph of a section through a capillary with two red blood cells.

Which group of structures are visible in a suitably stained plant cell using a high power (x400) light microscope?

Which is correct about the organelles listed in the table?

The electron micrograph shows some cell structures.

Some cell structures are listed.

1 nucleolus
2 chloroplast
3 microtubules
4 ribosomes
5 mitochondria
6 plasmodesmata
Which cell structures can be seen in the electron micrograph?

The electron micrograph shows a structure found in the cytoplasm of an animal cell.

What is this cell structure?

Which cell organelle does not contain nucleic acid?

Which process occurs in a mature red blood cell?

The diagram below is drawn from an electronmicrograph of an animal cell.

Which represents the same cell, seen under a light microscope at $\times 400$ magnification?
