The cell wall is part of the plant's apoplast. This structure provides support and protection for plant cells, as well as playing a role in transporting water and nutrients throughout the plant. The apoplast is the space outside of the plasma membrane where materials like water and nutrients can move freely.
Because it is the pH of the Apoplast. Cells are happy in it.
The apoplast and symplast pathways are two different pathways by which water can move through the root of a plant. Water in the apoplast pathway moves from cell to cell via spaces in the cellulose cell walls until it reaches the endodermis. At the endodermis, there is the 'apoplast block' - the cellulose cell walls of the cells of the endodermis have a substance called suberin which is impermeable and prevents the movement of water. The suberin makes up what is called the Casparian strip. At this point, all the water has to move into the vacuolar and symplast pathways. The function of the apoplast block is to prevent harmful substances from entering the xylem. The symplast pathway is where water moves from cell to cell in the cytoplasm via the plasma membranes and plasmodesmata. Water moves along the root by osmosis down a water potential gradient (as water moves into one cell, this cell then has a higher water potential than the adjacent cell, so water moves from cell to cell by osmosis). Water moves in this way along in the cytoplasm from the root hair cell to the endodermis.
Osmosis primarily occurs in the symplast pathway, as water moves through the living cells of the plant via plasmodesmata. The apoplast pathway, which involves movement of water through the cell walls and intercellular spaces, does not involve osmosis because osmosis requires a selectively permeable membrane, which is absent in the cell walls.

Water can move through the apoplastic pathway, which involves passing through the cell walls and spaces between cells, or through the symplastic pathway, which involves moving through the cytoplasm of cells via plasmodesmata. These routes help water reach the transport cells within the root for uptake and distribution.
The casparian strip is a waterproof barrier in the endodermis of plant roots that blocks the passive flow of water and minerals between cells. This ensures selective uptake of essential nutrients and prevents harmful substances from entering the stele.
If a protein allowing the movement of water from the apoplast into the symplast was inserted into the plasma membrane, it would disrupt the osmotic balance between the apoplast and symplast. This disruption in osmotic balance could hinder the efficient phloem loading of sucrose and nutrient transport in the plant.

Openings in plant leaves are called stomata. They are the point that carbon dioxide enters the plant, and the point that oxygen and water leave the plant. In the roots, there are no pores. Ions and water are absorbed either directly through the cell wall (apoplast) and plasma membrane via diffusion, or substances are taken through the membrane by various transporter proteins.
