About this course

A fun, fast-paced tour of modern biology from Crash Course, from ecology and evolution to cells, DNA and genetics, and how plants and animals work. Who it's for: school students (Class 9 to 12), NEET beginners who want the big picture first, and anyone curious about life science. These are the free, official videos of the Crash Course Biology playlist from the CrashCourse YouTube channel (youtube.com/@crashcourse). All videos belong to Crash Course; Sikhami is not affiliated with Crash Course and simply arranges the public playlist into a course, so you can learn one lesson at a time and keep track of your progress.

What you will learn

• What biology is, the scientific method and how life is organised • Ecology, climate change and conservation • Evolution, natural selection, speciation and the tree of life • Biological molecules and the cell: membranes, cell signalling, respiration and photosynthesis • Mitosis and meiosis, genetics, DNA replication, transcription and translation • Mutations, bacteria, viruses and vaccines, and bioinformatics • How plants and animals work: anatomy, defence, nervous and endocrine systems, reproduction and behaviour
