cell modifications Flashcards
The lining of the small intestine has tiny folds that projects out like numerous fingers.
cilia
They work in conjuction with the villi to absorb more nutrients
and more material because they expand the surface area
of the intestine.
Microvilli
What are the classifications of cilia?
A. motile cilia
C. non-motile cilia
B. villi
D. a&c
D.
Classification of cilia that move in a wave-like rhythmic motion
to keep sensitive internal passageways free from mucus or
foreign particles.
A. motile cilia
C. non-motile cilia
B. villi
D. a & c
A.
Classification of cilia that plays a crucial role in may organs
like in the kidney they are forced to bend as urine flows
past, which sends signals to the cells that urine is flowing.
A. motile cilia
C. non-motile cilia
B. villi
D. a & c
C
Cell modification that exhibit a wiggling or undulating movement that serves primarily to propel an entire cell.
flagella
Cell modification that promote the nutrient uptake ability of the
plant.
root hairs
Cell modification that plays an important role in regulating the heat and water balance of the leaves
trichomes
They are located on the inner surface of basal plasma membranes in contact with the basal lamina. They help to attach epithelial cells to the basal lamina.
A. hemidesmosome
C. desmosome
B. gap junction
D. tight junction
A
They form links between cells, and provide a connection between intermediate filaments of the cell cytoskeletons of adjacent cells. This structure gives strength to tissues.
A. hemidesmosome
B. gap junction
C. desmosome
D. tight junction
C
They are tubes that connect animal cells that are right next to
each other. Dissolved substances can pass through these tubes
but larger organelles can’t.
A. communicating
B. gap junction
C. nexus
D. all of the above
D.
This type of cell junction is located right below tight junctions and provides a strong bond between the sides of adjacent epithelial cell membranes.
A. hemidesmosome
B. gap junction
C. adhering junction
D. tight junction
C.
Their main functions are to make an impermeable barrier and
connect cells together.
A. hemidesmosome
B. gap junction
C. adhering junction
D. tight junction
C or D
A process that occurs after cell division where the newly formed cells are structurally modified so that they can perform their function efficiently and effectively.
