A cell is the basic unit of life in all living things. It’s like a small building block that makes up plants, animals, and even humans!
There are two main types of cells:
Plant cells – they have a strong outer wall and green parts called chloroplasts for making food.
Animal cells – they are rounder and don’t have a cell wall or chloroplasts.
Each cell has tiny parts inside it like:
Nucleus – the brain of the cell.
Cytoplasm – jelly-like fluid inside.
Cell membrane – the skin of the cell.
Mitochondria – the powerhouse that gives energy.
How do cells repair themselves after damage, and what happens when they can't?
What role do mitochondria play in energy production, and why are they called the "powerhouse" of the cell?
How do cells recognize and fight off infections?
What happens inside a cell during apoptosis (programmed cell death)?
How do plant cells differ from animal cells in terms of structure and function?
Can scientists create artificial cells, and what would be their potential uses?
