This unit enables you to understand the fundamental structure and functions of cells, essential to biological sciences. You'll compare prokaryotic and eukaryotic cells, detailing the specific structures and roles of cellular organelles within eukaryotes.

Additionally, you'll explore cellular processes including the regulation of substances across cell membranes, the utilisation of nutrients for cell activity, and the detailed mechanisms of protein synthesis, including the critical roles of nucleic acids in transcription and translation.

The unit also covers the cell cycle, examining the importance of embryonic stem cells in tissue development, detailing the stages of mitosis, and explaining how genetic information is accurately maintained and transferred to new cells during cell division.
