Organelles are absent in
(A) Type I alveolar cells
(C) Both of these cells
(B) Type II alveolar cells
(D) None of these cells
Answers
Answer:
Non of these
Explanation:
nucleus and numerous membrane-enclosed organelles (e.g., mitochondria, lysosomes, Golgi apparatus) not found in prokaryotes. Animals, plants, fungi, and protists are all eukaryotes.
ANSWER:
The 'type I cell' is devoid of organelles.
EXPLANATION:
Alveolar epithelium is divided in to two types of cells, the 'alveolar type I' and 'alveolar type II' cell. The type I cell is complex branched cell and these cells are found with 'multiple cytoplasmic plates' which are 'greatly attenuated' and do not contain organelles.
Type II is the helper cell of the alveolar component. This response to damage caused by 'vulnerable type I cell' by undergoing division and acting as the progenitor for both type I and type II cell. These type I cells comprise responsible for gas exchange surface for the alveolus and they are connect to maintenance of permeability function of alveolar membrane.
