What is the difference between apoplast and symplast pathways?

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 symplast pathway Class 11?

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. The pathway is slower when compared to the apoplastic pathway.

What is the difference between plasmodesmata and symplast?

Plasmodesmata connect neighbouring cells throughout a plant to establish the symplast. Plasmodesmata establish an interconnected cytoplasm called the symplast, through which metabolites, proteins, and RNAs are exchanged between cells, tissues, and organs.

What is the symplast pathway?

When water passes across from one living cell to another living cell through plasmodesmata, then it is called the symplast pathway. It is also called the trans-membrane pathway.

Which is faster apoplast and symplast?

The apoplastic pathway is fast. The symplastic pathway is slower than the apoplastic pathway. No effect on water movement. Metabolic states interfere with the flow of water in the symplastic pathway.

What is meant by apoplast pathway?

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 true for symplast and 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 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.

What is apoplast route?

The 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.

Why is symplast slower than apoplast?

(1) Because it involves cytoplasmic streaming always. (2) Molecule has to enter through the cell membrane. (3) Because it is down the gradient.

What is true for both symplast and apoplast?

An equal rate of transport.

Is apoplastic or symplastic faster?

Difference between Apoplast and Symplast Consists of non-living parts. Consists of living parts. The apoplastic pathway is fast. The symplastic pathway is slower than the apoplastic pathway.
