Answers
1).This is because it pakages material synthetised in the Endoplasmic Reticulam and dispatch into intercellular ( plasma membrane and lysomes ) and extra cellular ( cell surface) targets.
3). osmosis is a movement of a solvent across semipermiable membrane towards a higher concentration of solute (lower concentration of solvet) when a cell is submerged in water the water molecule passes through the cell membrane from an area of low solute concentration to high solute concentration.
4). ATP( Adenosine triphospate)
5). Types of plastids
* chromoplasts
* chloroplasts
* leucoplasts
Chromoplast : are the coloured plastids for pigment synthetise and storage. the pigment present in the leaves in which no more photosynthesis is occur
chloroplast : are the green plastids which contain chlorophyll pigments for photosynthesis.
Leucoplast : are the colourless plastids for monoterpene synthetise found in non-potosynthetic pasts of the plants.
6).
a). mitochondria
b). lysosomes
c). vacuoles
d). chloroplast
e). ribosomes
f). Golgi apparatus
g). nucleus
7). J.E. Purkinje
8). Structure :
*The plasma membrane is composed of a phospholipid bilayer, which is two layers of phospholipid back-to-back. phospholipids are lipids with a phosphate group attached to them.
The phospholipid have one head and two tail. the head is polar and hydrophilic or water-living.
Functions :
* protects the cell by acting as a barrier .
* regulates the transport of substance in and out of the cell.
* recives chemical messenger from other cell.
* acts as the receptor.
* cell mobility, secretion and absorption of substance.
