Which pathway is faster apoplast and symplast?
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 apoplast is faster than symplast?
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….

What is the symplastic pathway?
The symplastic pathway: It provides the movement of water from one cell to another cell by plasmodesmata. Symplast, is an inner side of the plasma membrane.
How is the apoplastic route of water flow different from a symplastic route?
In the apoplast pathway (apoplastic route), water moves through the spaces between the cells and in the cells walls themselves. In the symplast pathway (symplastic route), water passes from cytoplasm to cytoplasm through plasmodesmata (Figure 17.1.
What is meant by Apoplast pathway?
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.
Which of the following is Apoplast pathway?
| Apoplast pathway | |
|---|---|
| (i) | It consists of non-living parts of plant body, i.e., cell walls and intercellular spaces. |
| (ii) | There is little resistance in the movement of water. |
| (iii) | It is slightly slower. |
| (iv) | Metabolic state of root directly affects apoplast pathway. |
What is the symplast quizlet?
The symplast is the continuum of cytoplasm of bordering cells via plasmodesmata. The apoplast is the pathway that consists of extracellular spaces between cell walls.
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.
What is the function of apoplast?
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 meant by Apoplast pathway Why does it occur in cortex and not in endosperm?
Why does it occur in the cortex and not in Endodermis? In an apoplast pathway, water is transported from the root hair to xylem via the cell wall of the intervening cells. This pathway occurs in the cortex and stops once it reaches the endodermis as it has a band of impermeable matrices called the casparian strip.
What is the meaning of apoplast?
/ (ˈæpəˌplæst) / noun. botany the nonprotoplasmic component of a plant, including the cell walls and intercellular material.
Why does the casparian strip block the apoplast pathway?
The Casparian strip is impervious to water so can control the transportation of water and inorganic salts between the cortex and the vascular bundle, preventing water and inorganic salts from being transported to the stele through the apoplast, so that it must enter the cell membrane and move to the stele through the …
