“Cell division that involves growth, development, repair, and replacement of worn out tissues…”
Forget the big words for a second. Think about your own body.
When you get a small cut on your skin, after some days it closes up. That is your body repairing itself.
When you were younger and you kept getting taller, that was growth.
Even right now, cells in your body are dying and new ones are replacing them without you noticing.
So the question is simply asking:
“What type of cell division helps your body grow, heal, and replace old cells?”
That’s it.
Now there are two main types of cell division your body uses, and this is where everything becomes clear.
One type is for normal body activities like growth and repair.
The other type is for making s*x cells like man-fluid and egg.
The one for normal body activities is called Mitosis.
That is your answer.
So the correct option is B.
Now I want you to actually understand it so you never forget, not just cram it.
In mitosis, one cell divides into two identical cells. Same size. Same function. Same everything. It is like photocopying a page. You get two exact copies.
That is perfect for growth and repair, because your body just needs more of the same cells.
Now let’s look at the one they are trying to confuse you with, which is Meiosis.
This one is completely different.
Meiosis is only for producing man-fluid and egg. It reduces the number of chromosomes by half. It also produces cells that are not identical. This is for reproduction, not for repairing your skin or helping you grow taller.
So anytime you see words like growth, repair, healing, replacement, your brain should immediately say “mitosis.”
Now let’s go through the wrong options slowly so you can see how JAMB tries to trick you.
Option A says biosynthesis. That one sounds serious, I know. But biosynthesis just means the body is making substances like proteins or enzymes. It is not cell division. No splitting of cells is happening there.
Option D says synthesis. That is even more general. It just means “making something.” Again, no division of cells.
So both A and D are not even talking about cell division at all. They are just there to distract you with big words.
Option C is meiosis. This is the most dangerous distractor because it is actually a type of cell division. So your brain might panic and pick it. But now you know the difference.
If the question was about production of man-fluid, eggs, or s*xual reproduction, then meiosis would be correct.
But this question is about everyday body processes like growth and repair. That belongs to mitosis.
Let me give you a simple way to lock this in your head before your exam.
If it is about your body maintaining itself, think mitosis.
If it is about reproduction, think meiosis.
That’s it.
