Discussion Question: What are the main types of passive transport, and how do they benefit the cell?
The main types of passive transport are diffusion, facilitated diffusion, and osmosis. They benefit the cell by allowing molecules to move across membranes without energy, maintaining homeostasis efficiently.
Discussion Question: What are the two most useless types of cells?
Two types of "useless" cells are vestigial cells, like those in the coccyx (tailbone), which no longer serve a functional purpose, and senescent cells, which have stopped dividing and contribute little to tissue function, though they can still impact aging and health.
Discussion Question: What are the top 3 most crucial kinds of cells?
The top three crucial cells are stem cells (tissue regeneration), neurons (signal transmission), and erythrocytes (oxygen transport), all essential for growth, communication, and overall body function.
