How do moss plants get the food they need?

Mosses receive their water from rainfall and most of their nutrients are dissolved in this water that has accumulated as dust on them. Their nutrient uptake is effected by the osmosis. Highly concentrated nutrients can kill them because they have no ability to regulate the absorption.

They get the food they need by making photosynthesis getting their energy and food from the sun and to grow bigger moss plants make new cells through mitosis
