Cell Structure & Functions Flashcards
Golgi apparatus is used for?
Protein modification
What are the features of epithelial tissue?
Avascular (×blood and lymph vessels)
Polarity (difference between apical side and basal side)
Can regenerate
Which epithelium is located on heart and blood vessels and lymph?
Simple squamous epithelium
How many layers does psedo-columnar in trachea has?
1
Why is connective tissue separated by a basement membrane?
If there is a tumor in epithelium, the mutated cells may invade connective tissue to develop into cancer if not separated
What are the 2 examples of simple squamous epithelium? What are their functions?
Endothelium (for materials exchange)
Mesothelium (to reduce friction between organs)
5 types of epithelial tissues

Psedo-columnar in trachea
Glandular epithelium
What can collagen fibers be found?
In all connective tissues
Which protein fiber acts as a support mesh in soft tissue?
Reticular fibers
Common connective cell types

Which cell type of epithelium engulf bacteria?
Macrophage
Which cell type in neural tissue supports the neurons?
Glial cells
What is the composition of phospholipid bilayer?
Hydrophilic head + 2 hydrophobic tails
What are the 2 types of transmembrane protein on cell membrane?
