The correct option is B.
A multi cellular organisms has many cells which carry out various function and which are organised into tissues, organs and organ system. A unicellular organism on the other hand has only one cell with different cell organelles. Thus, in unicellular organisms, it is the cell organelles that carry out different functions. <span />
Answer:
C
Explanation:
First off, humans are considered animals, and since animal cells don't have chloroplasts, A and D are immediately incorrect. B is incorrect because lysosomes eject enzymes that digest materials in the cell, and to heal skin, you dont need to digest anything/ use enzymes to get rid if materials. That means the answer is C. The nucleus is the control center for the cell, so it tells the cell what to do. The mitochondria creates energy for the cell, and since it takes energy to heal, this answer is correct. (Tip- I find that using process of elimination in biology questions helps a lot.) Good luck!
