Question

1. As we have mentioned in the classroom, we can simply view that the cells are composed of “points”, “lines” and “planes”. Please use this simple “geometric” model and describe what type(s) of cell functions these components can contribute to. Also explain how (please do not mention anything such as proteins or lipids here). If we push into the detail a little bit harder, then we need to consider what the components of the “dots”, “lines” and “planes” are. Please describe the molecular information of those geometric features and explain how they can contribute to the cellular properties.

2. The cells are the fundamental life form. They interact with the environment (including the other cells and the extracellular matrix) to form tissues and organs. Please classify the tissues and explain their signatures.

Explanation / Answer

2. tissue is defined as a group of a cell which is capable to form an organ

tissue are classified as epithelial, connective, nervous and muscular tissue

Epithelial tissue covers body surfaces, connective tissue supports and binds body parts, nervous tissue response stimuli, and coordinate body function, muscular tissue movement of muscles or the whole structure
