False. When any spot on the earth is on the side facing the sun, that spot experiences a condition known as "daylight". At the moment when that spot is pointing directly toward the sun, the moment is called local "noon". The sun is then highest in the sky at that spot, and shadows are the shortest. All of these phenomena take place during the portion of the axial rotation period known at that spot as "day".
Yes it does. The spot is called 'The Great Dark Spot'
