Cell Division and Mitosis

Think of mitosis as nature's photocopying machine - it creates exact duplicates of cells when your body needs them. The process follows a simple cycle: growth, DNA copying, division, and splitting into two identical cells.

Here's how it works: a parent cell with pairs of chromosomes makes copies of its DNA, lines up all the chromosomes in the centre, then pulls the copies to opposite ends before splitting into two daughter cells. Each new cell has exactly the same genetic information as the original.

Your body uses mitosis for three main reasons: growth (making new cells as you get bigger), repair (fixing damaged tissues when you're injured), and development (creating specialised cells as different body parts form).

Remember: Mitosis only happens in body cells, not in sex cells (gametes). In plants, this process occurs in special areas called meristems.

Stem Cells - The Ultimate Shape-Shifters

Stem cells are like blank templates that can become any type of cell your body needs - they're unspecialised cells with amazing potential. They can divide through mitosis and then transform into blood cells, skin cells, nerve cells, or whatever your body requires.

There are two main types: embryonic stem cells can become absolutely any cell type, whilst adult stem cells (mostly found in bone marrow) are more limited and usually only make specific types like blood cells.

The medical possibilities are incredible - stem cells could treat diabetes, paralysis, and other conditions by replacing damaged cells. Therapeutic cloning involves creating cloned embryos to harvest perfectly matched stem cells that won't be rejected by a patient's immune system.

Key Point: Stem cell research faces challenges including infection risks and ethical concerns about using embryonic cells.

Plant Stem Cells and Cloning

Plants have their own version of stem cells located in meristems - special growth areas at the tips of shoots and roots. These cells keep dividing to help plants grow taller and their roots spread deeper.

Plant stem cells are brilliant for cloning because they can rapidly produce identical copies of entire plants. This technology is incredibly useful for saving rare species from extinction by creating multiple copies before they disappear forever.

Farmers and scientists also use plant cloning to mass-produce crops with special features like disease resistance or better nutrition. Instead of waiting years for traditional breeding, they can create thousands of identical plants with desirable traits quickly and efficiently.

Cool Fact: Unlike animal cells, plant stem cells at root and shoot tips can theoretically keep a plant growing indefinitely!

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
