Plant nutrition is the study of the chemical elements and compounds necessary for plant growth and reproduction, plant metabolism and their external supply. In its absence the plant is unable to complete a normal life cycle, or that the element is part of some essential plant constituent or metabolite .
The soil mineral apatite is the most common mineral source of phosphorus, from which it can be extracted by microbial and root exudates, [79] [80] with an important contribution of arbuscular mycorrhizal fungi. [81] The most common form of organic phosphate is phytate, the principal storage form of phosphorus in many plant tissues.
This allows the mollusks to survive solely by photosynthesis for several months at a time. [65] [66] Some of the genes from the plant cell nucleus have even been transferred to the slugs, so that the chloroplasts can be supplied with proteins they need to survive. [67] An even closer form of symbiosis may explain the origin of chloroplasts.
Air plants, or tillidansias, don't need soil to survive, but they do need water. Here's how to easily care for your air plants, according to experts.
In plants and animals, mineral absorption, also called mineral uptake is the way in which minerals enter the cellular material, typically following the same pathway as water. In plants, the entrance portal for mineral uptake is usually through the roots. Some mineral ions diffuse in-between the cells. In contrast to water, some minerals are ...

To photosynthesize, plants must absorb CO 2 from the atmosphere. However, this comes at a price: while stomata are open to allow CO 2 to enter, water can evaporate. [33] Water is lost much faster than CO 2 is absorbed, so plants need to replace it, and have developed systems to transport water from the moist soil to the site of photosynthesis. [33]
The function of all root hairs is to collect water and mineral nutrients in the soil to be sent throughout the plant. In roots, most water absorption happens through the root hairs. The length of root hairs allows them to penetrate between soil particles and prevents harmful bacterial organisms from entering the plant through the xylem vessels. [1]
