Processes. Plants take up essential elements from the soil through their roots and from the air through their leaves. Nutrient uptake in the soil is achieved by cation exchange, where in root hairs pump hydrogen ions (H+) into the soil through proton pumps
Plants absorb nutrients and water through their roots, but photosynthesis occurs in the leaves. So, plants need to get fluids and nutrients from the ground up through their stems to their parts that are above ground level.
there is an increase of the average global temperature due to the accumulation of polluting gases in higher atmospheric levels that causes regional and global climate change.
The F Ring, the Cassini Division, and the C Ring are bright ring features. They are bright due to the low concentration of materials within them, which allows sunlight to shine through.
