The Cell Theory is one of the big central theories in Biology. In this video I explain the three parts of the cell theory and some special cases.
All living things share the same functions of life, but may perform these functions differently. Here I compare the unicellular organisms Paramecium and Chlamydomonas in relation to the functions of life.
Multicellular organisms show emergent properties. Here I explain what these are.
The cells of a multicellular organism are specialized. This specialization happens due to cell differentiation.
During stem cell therapy, stem cells are injected into a patient. These differentiate in the body to replace (defective) body cells. In this video, I give two examples of stem cell therapy (Stargardt’s Macular Dystrophy and for Leukemia)
Stem cells may be obtained from embryos. This gives rise to a range of ethical issues.
The Cell Theory is one of the big central theories in Biology. In this video I explain the three parts of the cell theory and some special cases.
Stem cells are able to differentiate to form specialized cells. They also have retained the ability to divide. There are embryonic stem cells and adult stem cells.

Cells are small so that they have a large surface area to volume rato.
