Welcome everyone in the first episode of this podcast we are going to understand the key concepts of the first part of IB biology which are:
- According to the cell theory, living organisms are composed of cells
- Organisms consisting of only one cell carry out all the functions of life in that cell
- Surface area to volume ratio is important in the limitation of cell size
- Multicellular organisms have properties that emerge from the interaction of their cellular components
- Specialized tissues can develop by cell differentiation in multicellular organisms
