the wing flaps go up and down
It helps the plane balance. And on the planes tail it has two flaps on each side, and when these flaps go up it lifts the tail and the plane goes down, and when the flaps go down then then plane goes up.
The planes take-off with a catipulte but they have to be light planes nothing to heavy. Then the plane goes into full throtle flaps up then takes-off

planes are bigger than insects. insects are smaller than planes.
Airplane wings are designed to be most efficient when at high altitudes, traveling fast, while providing as little drag as possible. Unfortunately this design inst the best for takeoff and landing. Flaps are used to change the shape of the wing to accommodate takeoff and landing requirements. Most planes have flaps on the front of the wings (leading edge flaps) and at the back of the wings. During takeoff flaps increase lift so a plane can take off with limited runway length and lower speeds. As the plane gains speed the flaps are retracted. On approach and landing you want to fly as slow as possible so the flaps are deployed in increments till landing speed is achieved. Landing slower means less runway needed to stop.
Usually hydraulic rams in larger planes, but in model aircraft, it is electronic servo motors connected to push rods.
Not necessarily, flaps are used to increase surface area of the wing thus producing more lift and slowing it down but at low speeds of about 135 knots/240MPH it's effect is very minor on the speed.
Smaller planes have piston engines, but bigger planes like the Boeing 717-777 and other planes have turbine engines
they are smaller and have less power and a smaller engine.

They don't really need them to fly. However they are very useful for keeping a plane flying when you slow it down on landing and using flaps on take of means that you reach flying speed at a lower speed. The runways would have to be a lot longer if planes had to land and take of without flaps because they would have to land flat out at air speed.
