This free course, A tour of the cell, contains a blend of text and a multimedia interactive component to look at the uniformity and diversity within cells. Fundamental to understanding how cells 'work' is a knowledge of the subcellular components and how they are arranged. This is introduced through a series of in-text and self-assessment questions.

An interesting course that gives an overview of cell structure and what's inside cells. You will learn the main differences between plant and animal cells. Described as an intermediate level, some of the terms would be unfamiliar if you haven't done any biology before, but the included glossary is helpful.
A text-based course (no videos) with plenty of labelled electron microscope images and diagrams. And no quiz: you can receive a free certificate of participation after completing all the modules. -
it was amazing and helpful
This course was very helpful and helpful
The lessons are taught in a clear and fluent way and the pictures help to understand better
You don't need any previous information at all, this course will introduce you to the cells of your body from scratch
