When we talk about how complicated living things are, the type of cells they have is very important. There are two main kinds of cells: prokaryotic and eukaryotic. Let’s make it easy to understand the differences!
Prokaryotic Cells
- What They Are: These are simple, single-celled living things, like bacteria. They don’t have a nucleus.
- Size: They are usually smaller than eukaryotic cells, measuring about 0.1 to 5.0 micrometers.
- Structure: Their DNA is in a circular shape and floats around inside the cell, along with some other parts like ribosomes.
Eukaryotic Cells
- What They Are: These cells are more complex. They can be single-celled (like yeasts) or multi-celled (like humans, plants, and animals).
- Size: They are generally bigger, usually ranging from 10 to 100 micrometers.
- Structure: They have a nucleus that contains their DNA in straight strands. They also have special parts called organelles, like mitochondria and chloroplasts, that do specific jobs.
How This Affects Living Things
- Diversity: Eukaryotic cells can be more specialized. This means they can create complicated life forms, like humans, with different systems that work together.
- Adaptability: Prokaryotes are very adaptable. They can live in extreme places, showing how strong they are even if they are simpler.
To sum it up, the type of cells affects how life is organized and works, shaping the complexity of living things on Earth!
