Is the apoplast pathway faster?

Apoplast pathway is faster while symplast pathway is slightly slower. Metabolic state of root does not affect apoplast pathway while metabolic state of root directly affects symplast pathway.

Why is symplast pathway slow?

In the symplast, the water movement is slower. The metabolic rate of the cells in the root cortex does not affect the water movement. The metabolic rate of the cells in the root cortex highly affects the water movement. It shows less resistance to the water movement.

Which of the following is incorrect about the apoplastic pathway?

apoplast does not provide any barrier to water movement and water movement is through mass flow. mass flow of water occurs due to the adhesive and cohesive properties of water.

What is meant by Apoplast pathway Why does it occur in cortex and not in Endodermis?

Why does it occur in cortex and not in endodermis? The apoplast pathway involves the movement of water through the adjacent cell walls of the epidermis and cortex with out entering the cytoplasm. Thus, due to presence of caparian strips water does not move by apoplast in endodermis.

Which pathway is faster apoplast and symplast?

What is apoplastic pathway in plants?

The apoplastic pathway is one of the two main pathways for water transport in plants, the other being symplastic pathway. In apoplastic transport, water and minerals flow in an upward direction via the apoplast to the xylem in the root. Some of the ions that enter through the roots do not make it to the xylem.

Which of the following is true of Apoplastic pathway?

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.

Which is correct wrt Apoplastic pathway?

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. Thus, the correct answer is option B.

What is difference between apoplast and symplast?

The main difference between apoplast and symplast is that apoplast is a fully permeable route in which the water movement occurs by passive diffusion whereas symplast is a selectively permeable route in which the water movement occurs by osmosis.

What is apoplast and symplast pathway?

The symplast is the pathway in which the water molecules moves through the plasmodesmata region in the cells. The symplast is the living region present between two cells which connects one cell with the other. The apoplast pathway is the path in which the water is moving between the intercellular spaces.

What is apoplastic pathway Class 11?

apoplast pathway. symplast pathway. The apoplast is the system of adjacent cell walls that is continuous throughout the plant, except at the casparian strips of the endodermis in the roots. The apoplastic movement of water occurs through the intercellular spaces and the walls of the cells.

What is Apoplastic fluid?

The apoplast is a distinct extracellular compartment in plant tissues that lies outside the plasma membrane and includes the cell wall. The fluid obtained by this method is commonly known as apoplast washing fluid (AWF).

What is the apoplastic pathway for water transport?

The apoplastic pathway is one of the two main pathways for water transport in plants, the other being symplastic pathway. In apoplastic transport, water and minerals flow in an upward direction via the apoplast to the xylem in the root. The concentration of solutes transported in aboveground organs is established through a combination

What is the difference between apoplastic and symplastic movement?

(A) The apoplastic movement of water occurs exclusively through the cell wall without crossing any membranes. (B) Solutes present in a cell (or in any solution) increase the free energy of water or water potential. (C) The symplastic movement occurs from cell to cell through the plasmodesmata.

How does acidification of the apoplast increase plant growth rate?

In nitrate poor soils, acidification of the apoplast increases cell wall extensibility and root growth rate. This is believed to be caused by a decrease in nitrate uptake (due to deficit in the soil medium) and supplanted with an increase in chloride uptake. H+ATPase increases the efflux of H+, thus acidifying the apoplast.

What is the difference between active transport and passive transport?

Secondary active transport involves the use of an electrochemical gradient. Active transport uses cellular energy, unlike passive transport, which does not use cellular energy. Active transport is a good example of a process for which cells require energy. Why are cells so small? Cells are so small that you need a microscope to examine them. Why?
