If Biology has ever confused you with big terms like "cell division," "diploid," or "haploid" — don’t worry.
By the end of this thread, you’ll know the exact difference between mitosis and meiosis…
And remember it for life. 👇
1. Let’s start with the basics: What is cell division?
Cell division is simply when one cell splits to form new cells.
Why?
👉 To grow
👉 To replace old cells
👉 To produce reproductive (sex) cells
This happens through two main types:
Mitosis and Meiosis
Let’s break each down 👇
2. What is MITOSIS?
Mitosis is when a body cell divides into two identical daughter cells.
✅ These cells are clones — same number of chromosomes
✅ Used for growth, repair, and replacement of old cells
✅ Happens in all body (somatic) cells except sex cells
📌 Example:
If you injure your skin, new cells are made by mitosis to replace them.
💡 Keyword: IDENTICAL COPIES
3. What is MEIOSIS?
Meiosis is when a sex cell divides to form four daughter cells, each with half the number of chromosomes.
✅ Happens in the testes (for sperm) and ovaries (for eggs)
✅ Used for sexual reproduction
✅ It’s why you get a mix of genes from your mum and dad
📌 Example:
When sperm and egg are formed — it’s meiosis doing the work.
💡 Keyword: GENETIC VARIATION
4. Key Differences Between Mitosis and Meiosis:
Feature Mitosis Meiosis
Purpose Growth & repair Sexual reproduction
No. of divisions 1 2
Cells formed 2 identical cells 4 genetically different cells
Chromosome number Same as parent cell (diploid) Half of parent (haploid)
Occurs in Body (somatic) cells Sex (reproductive) cells
Genetic variation No Yes
5. Funny trick to remember the difference:
🧠 “Mitosis is Me – I grow”
So think: Me = Mitosis = Growth
🧠 “Meiosis is Marriage – baby making”
So think: Meiosis = Reproduction
😂 It might sound funny, but it works!
6. Common exam questions you might see:
✅ Define mitosis
✅ List two differences between mitosis and meiosis
✅ State two importance of meiosis in reproduction
✅ Where does mitosis occur?
📌 If you’ve read this thread well, you can now confidently answer all of them. 💯
7. Final summary (what to always remember):
Mitosis = Makes two identical cells
Meiosis = Makes four different cells
Mitosis = growth. Meiosis = reproduction.
Mitosis = 1 division. Meiosis = 2 divisions.
If you get this, you’ve won half the biology exam
