what is the function of the structure identified by the red arrow?

a) food capture

b) mobility

c) dna transfer

d) protection

2. what morphology is represented in the picture?

a) filamentous

b) cocci

c)rod-shaped q

d)spirilla

Part 1.

The correct answer is option D which is protection.

Explanation:The structure shown by red arrows is the outer membrane of the cell.Its function is to protect the cell from the outer environment by controlling the transport of materials in to and out to the cell.While for movement, there are pili or cilia, which are also used for food capture and DNA transfer.Pili are outward projections from outer membrane.Part 2.

The correct option is D which is spirilla shape.

Explanation:In the picture, there is long wire like cell which is present in a zig-zag like a snake.This shape in microbiology is termed as spirilla shape.While cocci are round, filamentous is a colony of cells/bacteria in line and rod shape means rod-like.Hence, in the picture there is a spiral shape cell or bacteria.

The  answer is b since it all happens under ground
