Water and minerals are transported within the plant by the Xylem vessels (mainly in an upward direction); these are part of the vascular system which also includes Phloem vessels.
Phloem transports the products of photosynthesis within the plant (mainly in a downward direction)
Mineralls are absorbed by the root hairs using active transport.
Plants employ osmosis to move minerals into plant root cells. To transport minerals to the plant proper, energy is required so active transport is employed.
Humans need the fiber found in plant materials. Also, several key vitamins and minerals can only be found in plants that have absorbed them from the soil, water and sun.
If by "food" you mean the product of photosynthesis, this is transported through the plant (from the leaves and green parts) by the Phloem vessels - this is generally in a downward direction. If by "food" you mean nutrients that are absorbed from the soil, these are absorbed in solution by the roots and then transported in an upward direction throughout the plant by the Xylem vessels
Xylem transports water up to the leaves.Water:Is absorbed from the soil through root hair cellsIs transported through the xylem vessels up the stem to the leaves.Evaporates from the leaves (transpiration)But the phloem transports nutrients to the leaves.
Minerals were not once plants and animals. This is because life is composed of cells and minerals do not contain cells.
It would die as water and minerals absorbed from the roots cannot be transported to other parts of the plant.Food made by the leaves cannot be transported to other parts of the plants too.So,the leaves and stems do not get the water and minerals absorbed by the roots.The roots and stems also cannot get the food made by the leaves.Hence,the plant will die eventually.
From the roots
Stem is the only one that will transport the water,food,mineral salts and sugar(food) to all parts of the plant. Because of stems,the water and mineral salts get to the leaves and other parts of a plant.
Nitrogen absorbed by the roots is either metabolized in the roots or is transported to the aerial part via the xylem. How N is transported depends on the form absorbed (NO3- or NH4+ ) and the metabolism of the roots.
Plants employ osmosis to move minerals into plant root cells. To transport minerals to the plant proper, energy is required so active transport is employed.
Diffusion,ion exchange and mass exchange is the mechanism of active absorption of minerals in plants.
Water and minerals are absorbed through the intestines. But some minerals like magnesium can be absorbed through the skin.
Water is absorbed by plant roots and transported, by capillary action, through the fibrous material of the plant stem, to the leaves.
Yes, cholesterol and peptides can be absorbed without being digested. Thanks chacha.com

The plants absorb minerals from the soil, since it is wet. When the soil is dry, there is no way for plants to absorb anything. That's what rain do, by making the soil wet, so that plants can absorb minerals through their roots.
There are 14 essential plant nutrients. Carbon and oxygen are obtained from the atmosphere, and the other nutrients are absorbed from the soil.
