1. Cell structure and Function
Key Takeaways
At the end of the chapter learners will be able to :
- Compare and contrast the structural and functional differences between prokaryotic and eukaryotic cells, plant and animal cells.
- Identify and describe the key organelles of eukaryotic cells and their roles in maintaining cellular function.
- Explain the chemical constituents of cells, including carbohydrates, proteins, lipids, nucleic acids, and their importance in cellular activities.
- Differentiate between the unique structures of plant cells and animal cells
Let’s start with a simple video introducing you to Cell structure and functions.

Cell is the basic and fundamental unit of a living thing.
- A living thing can be unicellular i.e., made of one cell only (like bacteria) or can be multicellular i.e., made up of many cells (like a human)
- A living thing, whether made of one cell or many cells is called an organism.
- Several cells of one kind interconnect with each other and perform a shared function forming tissues,
- Several tissues combine to form an organ (e.g stomach, heart, or brain), and
- several organs make up an organ system (such as the digestive system, circulatory system, or nervous system).
- Several systems that function together form an organism (like a human being).
- Basically all cells, are grouped into one of two broad categories as prokaryotic and eukaryotic.
- For example, both animal and plant cells are classified as eukaryotic cells, whereas bacterial cells are classified as prokaryotic
