Answer 1

Answer:

•An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body. Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins.

An organelle is a specific structure within a cell, and there are many different types of organelles. Organelles are also called vesicles within a cell. And they really have a function that's important, because we need to compartmentalize all the functions within the cell. So there needs to be a membrane around the mechanisms for making a different product within a cell. So really, organelles are all membrane-bound.

•Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. ... On the other hand, velocity is a vector quantity; it is direction-aware. Velocity is the rate at which the position changes.

Answer 2

cell oragaelles are membrane bounded structure which are present inside the eukaryotic cell. they are absent in prokaryotic cell. All cell organelles have their specific function. ex mitochondria, Golgi bodies and vacuoles etc

speed is the rate at which which object Cover distance. it is scalar quantity. formula s = distance/time

velocity is the rate at which object Cover displacement. it is a vector quantity. formula v= displacement/ time
