intro to cells



here are the last couple days worth of daily questions and the notes on cell structure and function so far.
Thursday October 10th
The cell is the basic unit of structure & function in all living organisms.

The human body has about 200 different types of cells with VERY different functions.  What determines the function of a liver cell compared to a kidney cell? The shape (structure) of the cells determine function.

The main difference between prokaryotic and eukaryotic cells is the presence or absence of what? A nucleus 

Tissue is composed of a group of
(1) similar cells working together
(2) different organs working together
(3) organ systems working together
(4) nuclei in a cell working together

Humans require organ systems to carry out life
processes. Single-celled organisms do not have
organ systems and yet they are able to carry out
life processes. This is because
(1)  human organ systems lack the organelles found in single-celled organisms
(2)a human cell is more efficient than the cell of a single-celled organism
(3)  it is not necessary for single-celled organisms to maintain homeostasis
(4)  organelles present in single-celled organisms  act in a manner similar to organ systems

The structures found in a living cell can be compared to the parts of a factory that produces cars. Which part of the factory is most similar to the nucleus of a living cell?
(1) a conveyor belt that transports materials
(2) a storage bin that holds the pieces needed to assemble a car
(3) the computer room that controls the assembly process
(4) the generator that provides energy for the factory 


We talked through this slide but I did not require you to write it in your notes.
