As oxygen is used in respiration (the process by which energy is made available) it is reasonable to suggest that the data support the hypothesis that mineral uptake by plants is an active process. However, the data for anaerobic conditions suggest that, in this experiment at least, diffusion can account for the uptake of some of the sulfate

Now we need to discuss how the water is transported against gravity from the roots to the leaves where it is needed for the process of photosynthesis. Water travels to the leaves via the stem. Recall, that three processes are necessary for the transport of water in plants, namely; transpiration, capillarity and root pressure.

Plants do not have a circulatory system. So how do they transport essential materials throughout their body? Well, they use molecules to transport nutrients from their roots to their stems, leaves, and other parts. Let us learn a bit more about transport in plants. Let us learn how are water and minerals transported in plants. Means of Transport.

The structure of plant roots, stems, and leaves facilitates the transport of water, nutrients, and photosynthates throughout the plant. The phloem and xylem are the main tissues responsible for this movement. Water potential, evapotranspiration, and stomatal regulation influence how water and nutrients are transported in plants.

Plants must transport water from the roots to the leaves where it is needed for the process of photosynthesis. Nutrients produced in the leaves by photosynthesis are transported to all the parts of the plant. The phloem carries nutrients up and down the plant. The xylem only carries water up the plant.

Even when no water is being absorbed, minerals enter freely-mostly through the root hairs. Minerals can enter against their concentration gradient; that is, by active transport. For example, plants can take up K + from the soil against a ten-thousand-fold concentration gradient; e.g., from as little as 10 µM in the soil to 100 mM in the cell.
