Cell Structure
Bayani Gaba-gaba
Every living organism, from the smallest bacterium to the tallest tree, is built from cells. Understanding how cells are structured is the foundation of biology: once you know what sits inside a cell and what each part does, you can explain how organisms feed, grow, respire and reproduce.
In this lesson you will learn the structures found in animal and plant cells, discover what makes them different, and explore how cell differentiation produces the specialised cells that multicellular organisms depend on. You will also weigh up the advantages and disadvantages of using stem cells in medicine.
