Plants are multicellular, eukaryotic organisms that obtain food by photosynthetic mode of nutrition.
Plants obtain essential nutritional elements from the soil via their roots and the atmosphere via leaves.
In leaves, the stomatal pores facilitate the intake of carbon dioxide and expelling of oxygen. The carbon dioxide gas obtained is utilized for photosynthesis.
The root hairs present on roots are essential for the uptake of nutrients.
Plants absorb nutrients throughout the day, all day and night and irrespective of whether light is present or absent.
