Read the following questions. Each question gives you a hint about a cell organelle, identify and write down its name.


Q1: Jelly like substance containing particles and other organelles. What is it?

Q2: A partially permeable layer prevents cell contents from escaping controls what substances enter and leave the cell. Identify?

Q3: A fluid-filled space surrounded by a membrane. Generally contains salts and sugars in plants.

Q4: Contains green colour pigment, traps light energy. Present in some plant cells.

Q5: Appear brown dots either present freely in cell or bound to a membrane and make proteins.



Q6: A tough, non-living layer, it prevents plant cells from bursting, freely permeable

Q7: A network of flattened cavities surrounded by a membrane, which links with the nuclear membrane. Help in packaging proteins.

Q8: Slipper or oval shaped, its inner membrane is multi-folded and has lot of chemical activity

Q9: Controls cell division and cell development.

Q10: Thread like structures made up of in DNA and proteins. Converts to chromosomes when cell is dividing.

Q11: Powehouse of cell

Q12: Digestive organelle where macromolecules are hydrolyzed

Q13: Membrane-bound vesicles arranged approximately parallel to each other. Active in synthesis, modification, sorting, and Secretion of cell products

Q14: Present in some animal cells, help in locomotion.

Q15: A structure involved in production of ribosomes, present inside a nucleus.

Q16: Called ‘suicide bags’ of a cell.

Q17: Detoxify drugs and poisons specially in liver cells.
