Answer:
Plant cell needs cell wall whereas animal cell do not because the plants need rigid structure so that they can grow up and out . ... So animal cells can have various shapes, but plant cells only have the shapes of their cell walls.

It has to be C.
1 is photosynthesis.
2 is fermentation in yeast (alcohol right there)
Proteins are modified within the nucols
Answer:
Bacterial flagella is the external structure that is thin, long and filamentous. It is attached to the cell wall of the bacteria which helps in the locomotion of the bacteria. It has three parts a filament, hook and basal body. The basal body is incorporated in the cell membrane.
A flagellum is made up of a protein called flagellin. It is a rigid protein and helps in making the hollow core of the filament by assembling together to form a structure which is cylindrical in shape.
The organization of flagella on bacterial cells is helpful in the identification of bacterial species. Mostly 4 type of organization of flagella is present on bacterial cell that are monotrichous, amphitrichous, lophoyrichous and perithrichous.
In monotrichious bacteria, only one flagella is present on one side, in amphitrichous both side of the cell have an equal amount of flagella. Lophotrichous bacteria have a group of flagella at one side of the cell and amphitrichous bacteria have many flagella distributed equally on its cell.
The exoskeleton of an arthropod is chitin.
