K.C.S.E Biology Q & A - MODEL 2017PP2QN01

The diagram below represents a nucleus.

​(a) Name the structures labelled E and F. 
(i) E
 F
(ii) State the function of F. 
(iii) With reference to the nucleus, state one difference between an animal and a bacterial cell.
(b) Name the plant cell organelle:
(i) that stores chlorophyll 
(ii) responsible for intracellular digestion. 
(c) State two main functions of the vacuole in the amoeba.

ANSWERS

​(a) E—Nucleolus;
F — Nuclear pore/nucleopore;
ii. Facilitates movement of materials in and out of the nucleus;
iii. Nuclear material in the bacterial cell is not enclosed within a membrane /prokaryotic, while in animal cell it is enclosed eukaryotic;
(b) i. Chloroplast; 
ii. Lysosome; 
(c) i. Feeding (food vacuole); 
ii. Osmoregulation (contractile vacuole);
iii. Excretion/removal of wastes;
