Question

Match List I (Physiological Processess) with List II (Cell organelles) and select the correct answer using the codes given below in the lists:

	List-I		List-II
A.	Photosynthesis	1.	Plasma membrane
B.	Mineral uptake	2.	Chloroplast
C.	Respiration	3.	Mitochondria
D.	Protein synthesis	4.	Ribosomes

• A. A - 2, B - 1, C - 3, D - 4
• B. A - 1, B - 2, C - 4, D - 3
• C. A - 1, B - 2, C - 3, D - 4
• D. A - 2, B - 1, C - 4, D - 3

Answer 1

The correct option is A A - 2, B - 1, C - 3, D - 4

• Chloroplasts are organelles found in plant cells and eukaryotic algae that conduct photosynthesis. Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant.
  
• Mineral nutrient concentration in roots may be 10,000 times more than in surrounding soil. During transport throughout a plant, minerals can exit xylem and enter cells that require them. Mineral ions cross plasma membranes by a chemiosmotic mechanism.
  
• Mitochondria are known as the powerhouses of the cell. They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy-rich molecules for the cell. The biochemical processes of the cell are known as cellular respiration.
  
• When a cell needs to make proteins, it looks for ribosomes. Ribosomes are the protein builders or the protein synthesizers of the cell. They are like construction guys who connect one amino acid at a time and build long chains. Ribosomes are special because they are found in both prokaryotes and eukaryotes.
  

So, the correct answer is 'A - 2, B - 1, C - 3, D - 4'.
