It does harm plant to water in the sun. During sunlight the stomata are wide open for gaseous exchange and this increases the rate of transpiration by the plant. Now if you water this plant, the air present in the soil will be replaced by water and roots will find it difficult to get enough oxygen for their respiration. Lesser respiration by the roots will absorb lesser water from the soil and wilting will take place.

Additionally, water droplets on the leaves can act as mini-magnifying glasses concentrating the rays of the sun and causing blemishes on the leaves (some plants are more prone to this than others).

Only if the water lies on the leaves then this magnifies the sun's rays and will scorch the leaf. The water will have more effect in early morning or after sundown as the plant can take it in better.

What grows faster a plant in the sun with no water or a plant in a closet with water?

A plant in the sun with no water would grow faster than a plant in a closet with water. Sunlight is essential for photosynthesis, the process that plants use to make their own food, while water is also crucial but not as immediately impactful as sunlight for plant growth.

What happens when you put a bag over a plant under the sun light?

Water droplets will form at the top of the bag. The water came from the leaves. When you water a plant, the water goes to the roots, and then the leaves. So the sun evaporated the water from the leaves and the water got stuck on the top of the bag. Transpiration is the process that caused this to happen.
