Answer: Police officer who allows selected people to enter and leave.
The cell membrane acts as the protective covering of the cell. This membrane is selectively permeable.
The membrane which is selectively permeable that allows only certain molecules to pass through it. The smaller molecules and the non polar molecules are passed through this membrane.
The molecules such as sugar and protein are not allowed to pass through the selectively permeable membrane.
In this way the cell membrane acts as policeman that allows the movement of selected people only.
This reaction gives the Starch and H2O as the reactants and Maltose as the product.
Amylase is an enzyme which helps in the digestion of Starch molecules and its activity can however be measured through careful monitoring of the disappearance of amylase substrate which is in this case, starch.
Plants are photosynthetic and autotrophic organisms, characterized by plant cells containing chlorophyll. The plants do not have locomation devices and are therefore immobile.
Photyosynthesis starts from inorganic ingredients (CO2 and H2O) to give an organic molecule (glucose) and oxygen at the end.
