Question 1 :
Assertion: The number of cells in a multicellular organism is inversely proportional to size of body.
Reason: All cells of biological world are of the same size.
Question 4 :
Which one of the following cell wall is not made up of cellulose?
Question 5 :
Assertion: Prokaryotic cells have no membrane bound organelles.
Reason: The cytoplasm of prokaryotic cells does not show streaming movement.
Question 6 :
When flagella are distributed all around a bacterial cell, the arrangement is called as
Question 7 :
Assertion: Organisms are made up of cells.
Reason: Cells are structural unit of living organisms. A cell keeps its chemical composition steady within its boundary.
Question 12 :
What regulates what enters and leaves the cell and provides protection and support in Animal cells?<br/>
Question 13 :
Assertion: Specialisation of cells is advantageous to organisms.
Reason: It increases operational efficiency.
Question 14 :
All performed an experiment in which they put two different cells P and Q in pure water. Cell P swelled up and burst eventually while cell Q became tight and firm but did not burst.<br/>Which of the following is the most appropriate inference?
Question 15 :
One of the following cell is connecting link between prokaryotes and eukaryotes, therefore, called as mesokaryote.
Question 17 :
Assertion: Cell wall is present in plant.
Reason: Animal cells lack cell wall.
Question 18 :
Correct the following statement.<br>Statement : Unicellular organisms do not respire, only multicellular organisms respire.<br>
Question 19 :
Which of the following structures is usually present only in animal cells?
Question 22 :
Select the correct sequence of molecules in cell on the basis of molecular size from the smallest to the largest.
Question 24 :
Consider the following statements<br/>A. Centrioles are present in almost all animals cells.<br/>B. Ribosomes are the site of protein synthesis.<br/>C. The middle lamella is the layer made up of calcium carbonate which holds the neighboring cells together.<br/>D. In animal cells, steroidal hormones are synthesized by smooth endoplasmic reticulum.The true statements are 
Question 25 :
Why erythromycin blocks protein synthesis of bacteria without harming its eukaryotic host?<br/>
Question 26 :
Assertion: The number of cells in a multicellular organism is inversely proportional to the size of the body.
Reason: All the cells in the biological world are of the same size.
Question 28 :
<br/>Which of the following best distinguishes a prokaryotic cell from a eukaryotic cell?
Question 29 :
Which cellular organelle would be concentrated at the top of the centrifuged mixture after centrifugation of cells containing solution?
Question 30 :
The plant cells are more rigid than the animal cell due to
Question 32 :
Which organelle would you expect to find in a plant cell but not an animal cell?<br/>
Question 33 :
Assertion: Cell is a structural and functional unit of an organism.
Reason: A cell keeps its chemical composition steady within its boundary.
Question 35 :
Most human cells range from 10 to 15 micrometers in diameters, What limits how large a cell can be?
Question 38 :
Which of the following characters distinguishes plant cells from animal cells?
Question 40 :
<br/>Which of the following is not a feature of prokaryotic cells?
Question 41 :
Which is the correct order for levels of organization in humans
Question 42 :
Which of the following structure is not found in plant cells?
Question 43 :
Statement I : All prokaryotes have a cell wall, eukaryotes do not.<br/>Statement II : Prokaryotes have a true nucleus, eukaryotes have a primitive nucleus.
Question 44 :
<br/>Which one of the following structures is not found in a prokaryotic cell?
Question 46 :
What is the difference in the vacuoles of both plant and animal cells?<br/>
Question 48 :
Assertion: Animal cell membranes are composed mostly of substance lipids and proteins.
Reason: Plant cell walls are made of cellulose.
