Question 1 :
If cells of onion peel and RBC are separately kept in hypotonic solution what among the following will take place?
Question 2 :
As lysosomes are organelles which on bursting can kill cells possessing them, they are called suicide bags. Is it true?
Question 4 :
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 5 :
Which kind of plastid is more common in root of the plant?
Question 6 :
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 7 :
When a red blood cell is kept in concentrated salt solution, they shrink and give a shrivelled appearance (crenation).
Is it true?
Question 8 :
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 9 :
Where do the lipids and proteins constituting the cell membrane get synthesized?
Question 10 :
Name the organelle which show analogy written as: Kitchen of the cell.
Question 11 :
Can you name the organelles we have studied that contain their own genetic material?
Question 12 :
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 14 :
Endocytosis is swallowing up of food and other substances (bacteria, viruses) from external medium by the plasma membrane. This is possible only when plasma membrane is in direct contact with external medium. It occurs only in animal cells. Is this true?
Question 15 :
Osmosis is diffusion of water from the region of its higher concentration (pure water or dilute solution) to the region of its lower concentration (strong solution) through a semipermeable membrane. Is it true?
Question 16 :
Name the organelle which show analogy written as: Transporting channels of the cell.
Question 18 :
Which kind of plastid is more common in flowers and fruits?
Question 19 :
When rheo leaves are boiled in water first and then a drop of sugar syrup is put on it, can we say that boiling shall kill the leaves?
Question 20 :
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 21 :
We eat food composed of all the nutrients such as carbohydrates, proteins, fats, vitamins, minerals and water. After digestion, they are absorbed in the form of glucose, amino acids, fatty acids, glycerol, etc. What mechanisms are involved in the absorption of digested food and water?
Question 22 :
Name the organelle which show analogy written as: Storage sac of the cell.
Question 23 :
The skin of your fingers shrink when you wash clothes for a long time due to exosmosis. Is it true?
Question 24 :
Name the organelle which show analogy written as: Digestive bag of the cell.
Question 25 :
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 27 :
Name the organelle which show analogy written as: Control room of the cell.
Question 28 :
If the organization of a cell is destroyed due to some physical and chemical influence, it will not be able to maintain homeostasis and thus will not be able to perform basic functions ( such as respiration, obtaining nutrition ,etc. )and such a cell will ultimately die. Is it true?
Question 29 :
Which cell organelle controls most of the activities of the cell?
Question 31 :
Name the organelle which show analogy written as: Packaging and dispatching unit of the cell.
Question 32 :
How do substances such as carbon dioxide and water move in and out of the cell?
Question 33 :
When the plasma membrane of a cell breaks down, it results in death of the cell as protoplasmic structures will get dispersed. Is it true?
Question 34 :
Name the organelle which show analogy written as: Power house of the cell.
Question 35 :
If the plasma membrane reptures or break down then the constant internal chemical composition of the cell will be lost and it will not be able to perform its basic functions. Is it true?
Question 36 :
As lysosomes are organelles which on bursting can kill cells possessing them, they are called suicide bags. Is it true?
Question 37 :
Which kind of plastid is more common in leaves of the plant?
Question 38 :
Do you agree that a cell is the building unit of an organism?
Question 39 :
If you are provided with some vegetables to cook, you generally add salt into vegetables during cooking process. After adding salt, vegetables release water. What mechanism is responsible for this?
Question 40 :
When golgi apparatus is removed from the cell, formation of lysosomes, secretory vesiscles will stop. Is it true?
Question 42 :
A cell having higher water content or hypotonic cell sap will undergo exosmosis and, therefore, lose water. It may undergo plasmolysis. Is it true?
Question 44 :
A cell having equal water concentration to its surrounding medium will neither gain nor lose water to the external medium.
Is it true?
Question 45 :
Name the organelles in plant cell that contain their own genetic materials and ribosomes.
