Convection
The convection zone in a star like the Sun is located just beneath the photosphere. It is the layer where energy generated in the star's core is transported to the surface via convection currents, providing the energy needed for the star to shine.
In an active transport, the cell uses energy (ATP) to transport the particle into the cell. Also, the particle moves through a "hallway" type thing. In a passive transport, the cell does not need energy (ATP) to transport the particle into the cell. Also, the particle just bursts through the cell membrane to get inside.
Active transport requires energy in the form of ATP to move molecules across the cell membrane against their concentration gradient, while passive transport does not require energy and relies on the concentration gradient to move molecules from an area of higher concentration to an area of lower concentration. Additionally, active transport can move molecules in both directions across the membrane, while passive transport can only move molecules down the concentration gradient.
The main difference is that diffusion does not require energy and active transport does require energy. Just for the record diffusion has a concentration that moves from high to low, and active transport has a concentration that moves from low to high. (Hope this helps to answer your question!)
Passive transport occurs when the concentration of something on one side of membrane is different from the concentration on the other side. It occurs when that substance can pass through the membrane, and always in the direction of more -> less. No energy is required to make the substance move; in fact, this movement generates energy. This is like rolling a rock down a hill--it just does it on its own.Active transport occurs in the opposite direction, from less -> more. It requires energy for transport. This is like rolling a rock up a hill--you have to push it the entire way!Both involve the transport of a substance across a membrane, and the change in concentrations on different sides of a membrane. Both are also important to the proper functioning of a cell.Active transport requires energy, but passive transport requires none.Active transport requires a special protein to make the transport occur, but passive transport requires none.
Convection is the dominant form of energy transport just below the photosphere of the Sun. Here, hot plasma rises, cools, and then sinks back down, creating a circulation pattern that helps transfer heat from the interior to the surface.

No, sunspots are "holes" in the sun's photosphere that allow you to see the layer just below. They are produced by concentrations of solar magnetic flux lines.
The Cromoshpere Is Found Just Above The Photosphere. For A Few Moments You Can See The Chromoshpere During A Solar Eclipse Or When Using a Special Instrument.
Active transport requires energy; passive transport does not.
No.... The Active Transport Requires Energy >> Just Energy But Our Bodies Transport a lot Of Substances Using Active Transport Including Water , Metal Ions, etc .......
Your mom...........no I'm just kidding, but there are some cars that regire no energy, but just solar power.

Facilitated diffusion is a type of passive transport (does not require energy). It is called facilitated diffusion because it utilises the carrier protein to diffuse through it. Active transport requires energy to pump certain big molecules to cross over and this uses transport protein. Basically, the difference is just the usage of energy.
Active transport requires energy in the form of ATP to move molecules across the cell membrane against their concentration gradient, while passive transport does not require energy and relies on the concentration gradient to move molecules from an area of higher concentration to an area of lower concentration. Additionally, active transport can move molecules in both directions across the membrane, while passive transport can only move molecules down the concentration gradient.
It is not actually dark, it is just dark in comparison to the rest of the Sun's photosphere. This is because the magnetic fields/flux associated with the sunspot inhibit convection and therefore reduce the amount of heat rising from below where they are present.
