Intercellular concentration, cytoplasmic matrix concentration, cytoplasmic fluid concentration

Cell sap is found in vacuoles, which are organelles that are unique to plant cells. Various organelles are suspended in the cytoplasm, and cytoplasmic matrix refers to the undifferentiated material in the cytoplasm except for the organelles (all organelles are differentiated from the cytoplasm).

For example, if you have seen a small balloon filled with water, the water inside is compared to the concentration of cell fluid, and the membrane of the balloon is the vacuolar membrane, and you put this balloon containing water in a bucket of water, and the water in the bucket is the cytoplasmic matrix. If you put a lot of these buckets in a pool with water, the water between the buckets is the intercellular concentration.

Of course, this is just for the convenience of visual understanding, in fact, these three substances "liquid" contain different things, and the concentration is not the same, in general, the concentration: intercellular fluid "cytoplasmic matrix" cell fluid, the three to form a certain concentration difference. This is to absorb water conveniently and maintain cell morphology.

There is no need to worry about bursting because plant cells have cell walls.

Hope it helps.

A intercellular concentration refers to the concentration of interstitial fluid between cells.

2. Cytoplasmic matrix concentration refers to the concentration of cytoplasmic matrix in the cytoplasm other than the organelles, excluding of course the concentration of cell fluid in the vacuole.

3. Cell fluid refers to the solution in all vacuoles of plants, so the concentration of cytoplasmic matrix and cell fluid are not the same.

The cell matrix is a component of the cell, and the content of the components is basically unchanged under normal circumstances, which is considered a quantification. Whereas cell fluid is a variable that exists specifically to make the cell osmotic pressure different.

If the cell is under abnormal conditions, the cell matrix changes the intracellular concentration, then it will also change the osmotic pressure (i.e., the ability to absorb water) of the whole cell, but the cell matrix usually remains unchanged, and its concentration and components are basically constant.

You know the intercellular space, so let's not talk about it.

Cytofluid generally refers to the cytoplasm in vacuoles.

Cytoplasmic matrix refers only to the cytoplasm in the cell membrane excluding the vacuoles.

The concentration of cytoplasm, cytoplasmic matrix, and external solution at the time of plasma wall separation is the concentration of the external fluid in which the cell is located and the concentration of the cell fluid (the liquid in the vacuole).

The conditions for the separation of high and medium plasmic walls are: first, there is a semi-permeable membrane, and second, there is a certain concentration difference between the solutions on both sides of the semi-permeable membrane.

The semi-permeable membrane here actually refers to the protoplasmic layer, that is, the cell membrane, the vacuolar membrane and the protoplasm between the two membranes; The concentration difference here refers to the difference between the concentration of the cell fluid and the concentration of the external solution.

Summary. Higher than.

+H+ concentration in the cell fluid + (fill in "above" or "below") +H+ concentration in the cytoplasmic matrix. + This difference is main.

Higher than. Please do you need the answer to that question?

A cell is separated in the plasma wall.

state, at which time the cell fluid concentration may be large and trapped at or equal to or less than the external solution concentration, a wrong;

Due to the cell wall.

It is a fully permeable and protoplasmic layer of fibrila.

It is selectively permeable, so there is an external solution between the cell wall and the protoplasmic layer, b is wrong;

c. Plasma wall separation refers to the separation of the protoplasmic layer from the cell wall, which is correct;

d. The elasticity of the cell wall is less than that of the protoplasm layer, resulting in the separation of the protoplasmic layer from the cell wall, and D is wrong

Therefore, it is chosen: C

The flow of water from the low concentration of the solution to the high concentration of the solution, the lack of water and wilting is a manifestation of cell water loss, so the concentration is that the intercellular space is greater than the cytoplasmic matrix is greater than the cell sap, so option C is correct

Therefore, c

Plasmo-wall separation compares the concentration of the cell's external fluid with the concentration of the cell fluid (the fluid in the vacuole).

The conditions for the separation of high and medium-to-high plasmic walls are: first, there is a semi-permeable membrane, and second, there is a certain concentration difference between the solutions on both sides of the lead-carrying semi-permeable membrane.

The semi-permeable membrane here actually refers to the protoplasmic layer, that is, the cell membrane, the vacuolar membrane and the protoplasm between the two membranes; The concentration difference here refers to the concentration difference between the concentration of the cell blogging fluid and the external solution.

1.When the concentration of the cell fluid (lower than the concentration of the external solution) is lower, the cell continues to lose water, causing the plasma-wall separation;

2.When the concentration of cell fluid is higher (than the concentration of the outside world), the cell continues to absorb water and the plasmo-wall separation gradually recovers.

Plasmo-wall separation. The comparison is between the concentration of the fluid outside the cavity in which the cell is located and the concentration of the cell fluid (the fluid in the vacuole).

The conditions for the separation of the high and medium-sized walls are: first, there is a semi-permeable membrane.

Second, there is a certain concentration difference between the solutions on both sides of the semi-permeable membrane.

The semi-permeable membrane here actually refers to the protoplasmic layer, which is the cell membrane.

vacuolar membrane and protoplasm between two membranes; The concentration difference here refers to the difference between the concentration of the cell fluid and the concentration of the external solution.

The concentration in the cytoplasmic matrix is less than the concentration of the liquid in the cell, and due to osmotic pressure, the large liquid (water) in the cell matrix is transferred from the inside of the cell to the outside of the cell, resulting in the separation of the cytoplasmic wall.
