In apoplastic movement, water moves from cell to cell through the intercellular spaces or walls of the cells and hence on the outer side of the plasma membrane. Majority of the water in roots is carried by the apoplastic pathway, except at the casparian strip.
What is the symplastic pathway?
In symplastic pathway, the movement of water is in between the cytoplasm and the vacuoles through the plasma membranes and plasmodesmata and beyond the cortex of plant cells. In this symplastic pathway, water moves from one cell to another cell by osmosis viz.

Which of the following is part of the Apoplast?
The apoplast pathway comprises of non living components of a plant body i.e., intercellular spaces and cell wall. The movement through apoplast is unregulated and fast. Symplast comprises of living components i.e., protoplasm, cell membrane and plasmodesmata.
What is Apoplastic movement of water?
Apoplast is the route the water moves through the cell walls and intercellular space of the root cortex. In the symplastic route, the water moves through the protoplasts of the root cortex. The apoplast route is the fully permeable route in which the water movement occurs in passive diffusion.
What is the role of Apoplasm?
Apoplast is the space outside the plasma membrane that allows free movement of material. This route plays a crucial role, and allows diffusion of a solvent across the tissue or organ.
What is apoplastic movement of water?
Is symplastic movement active?
In the active absorption, the water first enters the cell sap and passes from one cell to another. This type of movement where protoplasm is involved is called symplast. In passive absorption, water moves through the apoplast of the root.
What are the 4 types of tissue?
There are 4 basic types of tissue: connective tissue, epithelial tissue, muscle tissue, and nervous tissue. Connective tissue supports other tissues and binds them together (bone, blood, and lymph tissues). Epithelial tissue provides a covering (skin, the linings of the various passages inside the body).
Which tissue types are described as excitable?
Nervous and muscular tissue are both described as excitable tissue.
What is apoplastic and symplastic movement in plants?
What is the function of apoplast?
What is the apoplastic pathway?
What is Apoplast. The apoplast refers to the non-protoplasmic spaces of a plant. It includes the cell walls and the intracellular spaces. The apoplast of the root cortex is used for the movement of water to the xylem, which is absorbed by the root hair cells. This pathway is called the apoplastic pathway.
Apoplast is the space outside the plasma membrane that allows free movement of material. This route plays a crucial role, and allows diffusion of a solvent across the tissue or organ. The response to different environmental and biotic stimuli in apoplast can be an oxidative or respiratory burst (Fig. 1 ).
What is the difference between apoplastic and symplast?
Apoplast includes the non-living components of a plant such as cell walls and the intracellular spaces. Symplast includes the living components of a plant such as protoplasms. The water moves by the apoplastic pathway by passive diffusion.
What is the structure of apoplastic transport?
Structurally, the apoplast is formed by the continuum of cell walls of adjacent cells as well as the extracellular spaces, forming a tissue level compartment comparable to the symplast. The apoplastic route facilitates the transport of water and solutes across a tissue or organ. This process is known as apoplastic transport .
