Question 1 :
If the organisation of a cell is destroyed due to some physical or chemical influence, what will happen?
Question 3 :
If there was no golgi apparatus, there would not be any lysosome for intracellular digestion and cleansing, not complexing of molecules, no exocytosis and no formation of new plasma membrane. Is it true?
Question 5 :
Name the organelle which show analogy written as: Transporting channels of the cell.
Question 6 :
Name the organelle which show analogy written as: Control room of the cell.
Question 7 :
When dry apricot are left for some time in pure water and later transferred to sugar solution, can we say that when placed in pure water, dry apricots swell up due to endosmosis. On being transferred to sugar solution, they shrink due to exosmosis?
Question 9 :
The diffusion of water or solvent through a semi-permeable membrane from a solution of lower concentration of solutes to a solution of higher concentration of solutes is called _______.
Question 10 :
Plasma membrane is called selectively permeable membrane because it allows the movement of only selected molecules across it. State true or false
Question 12 :
Which kind of plastid is more common in root of the plant?
Question 13 :
Which kind of plastid is more common in flowers and fruits?
Question 14 :
Can you name the organelles we have studied that contain their own genetic material?
Question 15 :
Lysosomes are called scavengers of the cell because they remove cell debris consisting of dead and worn out cell organelle by digesting the same. Is it true?
Question 16 :
How do substances such as carbon dioxide and water move in and out of the cell?
Question 17 :
A cell having low water concentration or hypertonic cell sap will undergo endosmosis and absorb water from outside. It would become turgid. Is it true?
Question 18 :
Plasma membrane is called selectively permeable membrane because it allows the movement of only selected molecules across it and not all of them. Is it true?
Question 19 :
Mitochondrion is known as the powerhouse of the cell because it contains enzymes that are needed for stepwise oxidation of food stuffs (carbohydrate, fats or lipids and proteins) present in the cells to $CO_2$ and water. Is it true?
Question 20 :
