Question
TOPIC 2.9 Compartmentalization
The following data were collected by observing subcellular structures of three different types of eukaryotic cells.
Based on an analysis of the data, identify a likely primary function of each cell type and explain how the data support the identification.
Answer/Explanation
Ans:
Based on an analysis of the data, identify a likely primary function of each cell type and explain how the data support the identification. (3 points maximum)
Cell X likely functions in locomotion because it has a large number of mitochondria, which perform cellular repisation and synthesize ATP, which provides the energy needed for movement. Cell X also has ailia, which are used for movement.
Cell Y likely functions to synthesize and excrete proteins and compounds needed elsewhere in the organism, because it has a large amount of smooth and rough ER, which function in protein synthesis and processing (and rough ER has ribosomes’, which actually perform protein synthesis), and a large number of Golgi bodies, which package and ship at proteins.
Cell Z may be a surface or epithelial cell that serves no function except for protection or insulation, since it locks many organelles used for other functions.
