What is symplast in plants?

The symplast is all the cytoplasm of the plant, interconnected by plasmodesmata. The apoplast is all the cell walls and spaces that surround the symplast. The apoplast is comparable to a sponge that is full of water.

What is the apoplast of a plant?

Nowadays, the apoplast is defined as the intercellular space filled with gas and water, contained between cell membranes, the interfibrillar and intermicellar space of the cell walls, and the xylem extending to the rhizoplane and cuticle of the outer plant surface (Figure 1).

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 in biology?

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 symplast and apoplast?

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. The apoplast includes the non living spaces between the cells and the cell membranes.

What is apoplast route in biology?

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 apoplast in biology?

Inside a plant, the apoplast is the space outside the plasma membrane within which material can diffuse freely. It is interrupted by the Casparian strip in roots, by air spaces between plant cells and by the plant cuticle. This process is known as apoplastic transport.

What are the symplast and apoplast in the plants?

Symplast refers to the continuous arrangement of protoplasts of a plant, which are interconnected by plasmodesmata. Apoplast consists of non protoplasmic parts such as cell wall and intracellular space. Apoplast composed of nonliving parts of a plant. Symplast composed of living parts of a plant.

What is the difference between apoplast and symplast?

The apoplast includes everything outside the plasma membrane of living cells and consists of cell walls, extracellular spaces, xylem, phloem, and tracheids. The symplast, in contrast, consists of the entire cytosol of all living plant cells and the plasmodesmata – which are the cytoplasmic channels interconnecting the cells.

What is the apoplast path in plants?

The apoplast path includes the cell wall and intercellular spaces. Apoplast and symplast are two separate pathways in plants that initiate the passage of water along with ions from root hair via root cortex to xylem elements. These routes may exist either simultaneously or separately having different rates.

What does sysymplast mean?

Symplast: The symplast consists of protoplast. Apoplast: The apoplast is composed of nonliving parts of a plant. Symplast: The symplast is composed of living parts of a plant. Apoplast: The water movement occurs by passive diffusion. Symplast: The water movement occurs by osmosis.

What is the function of apoplast?

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.
