Transcript
Cells, Tissues, Organs and Systems Assessment
Science 8
1. Analyze the characteristics of cells and compare structural and functional characteristics of
plant and animal cells. You may wish to include diagrams with your written answer.
Hint: Include topics such as:
 characteristics of life (growth, movement, reaction to stimulus , reproduction),
 single-celled, multi-cellular
 food intake
 movement
 cell division
 selectively permeable membrane
 diffusion, osmosis
 cell wall, cell membrane, vacuole, nucleus, cytoplasm, mitochondria, chloroplast, etc.
(CS 8.1)
2. A) Identify the following parts of the compound microscope. (CS 8.2)
12345-
B) Calculate the magnification of the following cell, which is shown under the high power field
of view. (CS 8.2)
Low power objective = 10x
High power objective = 100x
Low power field of view = 3 mm
3. Explain the many structural and functional relationships among cells, tissues, organs and
organ systems in humans and describe two examples of science and technology based careers
in Saskatchewan that require an understanding of this knowledge. You may wish to include
diagrams with your written answer.
Hint: Include topics such as:
 specialization of cells
 muscles, nerves, epithelial and connective tissue
 respiratory system, circulatory system, digestive system, excretory system, nervous
system
 cell theory, human body composition theories (past and present)
(CS 8.3)
4. Analyze how the interdependence of organ systems contributes to the healthy functioning of
the human body. You may wish to include diagrams with your written answer.
Hint: Include topics such as:
 First Nations and Metis perspectives
 reacting to internal and external stimuli (viruses, bacteria, alcohol, drugs, dust and
temperature changes)
 obtaining nutrients and ridding the body of wastes,
 the impact of personal lifestyle choices (nutrition, exercise, smoking, drugs and alcohol),
 failure or removal of one organ
 personal and societal issues of using technology (pacemaker, artificial hip, prosthetic
limbs, artificial heart),
 maintenance of the body (energy drinks, dairy products, vaccinations, vitamin
supplements)
