Introduction to cells

It has been a while since I made a blog post!!  We have been doing a lot of introductory activities for this chapter including some book work and videos.  We started to get down the notes and today some of you had an open notes quiz on what we took yesterday.  To start the class though we had the following daily questions

After this we continued in the notes through some of the main organelles.  Please check Edline for the complete "Cell Structure and Function" Presentation.

Daily Questions - October 17th

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
