Animal cells, plant cells and prokaryotic cells have similarities and differences in their structure. Table 1.1 lists five organelles found in cells. Complete Table 1.1 by placing a tick (✔) to show whether the organelle is present in animal cells, plant cells and prokaryotic cells or a cross (X) if the organelle is absent. Put a tick (✔) or a cross (X) in every box. The first row has been completed for you. [Table 1.1]
- (a)Animal cells, plant cells and prokaryotic cells have similarities and differences in their structure. Table 1.1 lists five organelles found in cells. Complete Table 1.1 by placing a tick (✔) to show whether the organelle is present in animal cells, plant cells and prokaryotic cells or a cross (X) if the organelle is absent. Put a tick (✔) or a cross (X) in every box. The first row has been completed for you. [Table 1.1, partially filled][4]
- (b)(i)Name the structures labelled P.[1]
- (b)(ii)Explain how the organelle labelled Q in Fig. 1.1 is involved in this process.[2]
