Therefore, an amoeba will move the whole body toward a crumb cake (food) by
taxis movement (B)

2. Golgi bodies — as concerned with the production of substances by this cell.
Nearly all cell secretions are glycoproteins, i.e. proteins conjugated with a
carbohydrate. i.e. Golgi-body will be concentrated in the environment of
cell (B)

3. Tissue is a group of cell that have similar structures and performing a
function e.g. bone, blood of man (C)

4. Animal cell do not have cellulose cell wall, c hioroplast and sap vacuole.
The correct option is D.

nucleus (C)

6. Epiphyte grow on their host to get direet sunlight (B)

7. The collection of flower is called corrolla (D)

8. Osmosis the movement of any solvent molecule through a semi-permeable
membrane from a region of high concentration to a region of low concentration
(D) e.g. high water concentration to low water concentration.

9. 4H20 + chlorophyll —> 4(OH) + 4H) 4(OH) —> 2H2O + O2
The oxygen produced during photosynthesis comes from water (B)

10. i.e. to kill and softenthe tissue (D)

hooks (B)

15. The wall of the right ventricle are made of muscle but not quite so thick
as the left
ventricle (both are thicker than auricle). The right reticule contracts,
forcing blood
to close the tricuspid valve so that blood can only leave the ventricle by
opening into the pulmonary artery (C).
