Understanding Cells

Cells are the basic units of life, making up every living organism on Earth. They come in two main types: prokaryotic (like bacteria) and eukaryotic (like plants and animals).

Key Cell Components

• Nucleus: The control center, housing DNA.
• Mitochondria: The powerhouse, producing energy (\( \text{ATP} \)).
• Chloroplasts: Site of photosynthesis in plant cells.
• Cell membrane: Regulates what goes in and out.
• Ribosomes: Make proteins.

Prokaryotes vs. Eukaryotes

Prokaryotic cells have no nucleus or membrane-bound organelles, while eukaryotic cells do.

Why Cells Matter

Understanding how cells work helps us grasp how organisms grow, heal, and fight off diseases.

Real-World Impact

Studying cells leads to advances in medicine—like how antibiotics target bacteria without harming human cells.
