Answers
Required Answer:-
The very tiny hair like structures all over the body of a paramecium are cillia which helps in the locomotion and movement of the organism.
How do they help?
Locomotion of paramaecium is only possible due to the presence of numerous cillias.
It helps the body to move forward as well as backward in aquatic surface (mostly).
In short, whip like movement.
While moving forward, they move from anterior to posterior part and vice-versa.
They also help in catching prey (feeding of an organism).
It helps to remove the foreign particles and contaminates trying to move inside the paramecium..
Answer:
Area Of Sector
It consists of a region bounded by two radii and an arc lying between the radii. The area of a sector is a fraction of the area of the circle. This area is proportional to the central angle. In other words, the bigger the central angle, the larger is the area of the sector.
