What is the function of the structure identified by the red arrow?
Asked by maham237 @ in Biology viewed by 377 People
O Food capture
O Mobility
DNA transfer
O Protection
Answered by maham237 @
Answer:
Protection
Explanation:
It looks like that the picture depicts bacterial cells forming a colony. The structure shown by the red arrow is a cell membrane. The principle function of the cell membrane is to protect the cell internal environment with respect to changes in the external environment. This is also called homeostasis.
For food capturing and mobility, the structure is not matching because there should be filaments or pseudopodia. Likewise, for DNA transfer, pili are required and the shown structure doesn't match that too.
