Pesky Protist Group Sign up

Please note

All Life Science students.

Each block must cover aa total ten protists listed below.

Each individual groups in each block are to be one or two members.

In classes of less than 20 students some groups will have to do a parasite on their own.

Select a partner and sign up on list in room 411 on Tuesday next week.

1.     Entamoeba hystolytica
2.     Giardia lamblia
3.     Leishmania donovani
4.     Balantidium coli
5.     Trichomonas
6.     Pneumocystis carinii
7.     Plasmodium
8.     Trypanosoma cruzi
9.     Trypanosoma brucei
10. Toxoplasmosis gondii

Life Sciences Bacteria and Protist Jan 13th 2020

 

Topic Key Points Resource
Bacteria Phone Lab Testing how much bacteria on phone before and after antiseptic wipe Which gets read of more bacteria, a disinfectant or an antiseptic. Which is used on living surfaces
  Remember your petri dish number is both your block and class room number.

Note that sample a is before using wipe, and b is after using wipe

 Make sure to have three photos.

1 start of incubation

2. one day after incubation

3. two days after incubation

Anatomy and Physiology (muscle cells) Jan 10th 2020

Anatomy and Physio Tissues Labs (Muscle Tissue) Jan 8th 2020

 

 

Topic Key Points Resource

 
Organs are made of tissues Worksheet labelling tissues found in anatomical structures

Three  types of muscle tissue

Skeletal muscle

Cardiac muscle

Smooth muscle

 Overview by Khan academy

https://www.khanacademy.org/science/high-school-biology/hs-human-body-systems/hs-body-structure-and-homeostasis/a/tissues-organs-organ-systems

 
Skeletal muscle Are defined by structure and function

a)     Voluntary (controlled movement)

b)    Striation due to overlapping protein.

c)     Due to overlapping muscle bundles they appear multi nucleated

 https://courses.lumenlearning.com/ap1x94x1/?s=lab+5.6

 
Cardiac Muscle Are defined by structure and function

a)     Involuntary ( autonomic nervous)

b)    Cylindrical fibres

c)     Intercalates discs ( join cells )

What is the function of the intercalated discs?

 https://opentextbc.ca/anatomyandphysiology/chapter/10-1-overview-of-muscle-tissues/

 

 
Smooth muscle Are defined by structure and function

a)     Spindle shaped fibres

b)    Central nuclei

c)     Found in walls of internal organs or viscera.

d)    Contracts (involuntary via autonomic system.

e)    Called “smooth” due to lack of striation

Which organs have smooth muscle?

Anatomy and Physio Tissues Labs ( Epithelial Tissue) Jan 8th2020

https://www.khanacademy.org/science/high-school-biology/hs-human-body-systems/hs-body-structure-and-homeostasis/a/tissues-organs-organ-systems

 
Epithelial tissues Are defined by

a)     Layers ( simple or striated)

b)    Shape of cells

Squamous

Cuboidal

Columnar

c)     Cell membrane structurs such as cilia

 https://courses.lumenlearning.com/ap1x94x1/chapter/examining-epithelial-tissue-under-the-microscope/

 
Role of tissues Note: diversity of names of epithelial tissue is due to diversity of functions of the tissue.

Functions (5):

Absorption

Barrier

Protection

Secretion
