K.C.S.E Biology Q & A - MODEL 2017PP2QN01
The diagram below represents a nucleus.
(a) Name the structures labelled E and 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.
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;
(c) i. Feeding (food vacuole);
ii. Osmoregulation (contractile vacuole);
iii. Excretion/removal of wastes;
