Cell Structure and Function

Well it has been a WHILE since I have posted on here guys!!!  We are full force into our chapter on cell structure and function.  You have all the notes you need on the cell theory, the two types of cells (prokaryotic and Eukaryotic) as well as the different organelles and their functions.  We will spend a little more time going over these different organelles and how they all work together to make a cell run.

We did have daily questions today and last wednesday.

These groups of cells represent different

(1) tissues in which similar cells function together

(2) organs that help to carry out a specific life activity

(3) systems that are responsible for a specific life activity

(4) organelles that carry out different functions

Which sequence lists the levels of organization in the human body from simplest to most complex?

(1) organ system >tissue >cell >organ

(2) tissue >cell >organ >organ system

(3) organ >organ system >tissue >cell

(4) cell >tissue >organ >organ system

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

If a cell is like a city, what part of the cell would be the: 

“control center” - The Nucleus

“Recycling Center” - The Lysosomes

“Post Office” - The Golgi Apparatus
