Learn: Eukaryotes & Prokaryotes

Welcome!Today we'll explore Eukaryotes and Prokaryotes. These are two types of cells that make up all living organisms. Let's break it down step by step!

What are Cells?Cells are the basic building blocks of all living organisms. They provide structure and carry out essential functions for life. There are two main types: Eukaryotic cells and Prokaryotic cells.

Eukaryotic CellsThese cells have a nucleus (a structure that contains DNA) and membrane-bound organelles such as mitochondria. Examples include animal and plant cells. They are generally larger and more complex than prokaryotic cells.

Prokaryotic CellsProkaryotic cells do not have a nucleus. Instead, their DNA is free-floating in the cytoplasm. They also lack membrane-bound organelles. Examples include bacterial cells. They are simpler and smaller than eukaryotic cells.

Key DifferencesEukaryotic cells are larger, have a nucleus, and contain organelles. Prokaryotic cells are smaller, lack a nucleus, and do not have organelles. Prokaryotic cells often have structures such as a cell wall, plasmids (small loops of DNA), and flagella for movement.

MicroscopyMicroscopes allow us to observe cells closely. Light microscopes are useful for viewing cell structures, while electron microscopes provide higher magnification for detailed images of organelles and cell components.

Review Time!Great work! You've learned about the differences between eukaryotic and prokaryotic cells, their features, and microscopy. Let's test your understanding with a few questions.
