<h2>
Answer:</h2>
There are three types of meristems on the basis of position, i.e
- Apical meristem.
- Lateral meristem.
- Intercalary meristem.
<h2>
Explanation:</h2>
A meristem is the tissue present in most plants containing undifferentiated cells, found in zones of the plant where growth can take place. Generally differentiated cells(the cells other than meristems) do not divide and produce of a different type of cells.
Meristems are classified on the basis of their location in the plant:
- Apical meristem - these are the meristems located at root and shoot tips of the plant.
- Lateral meristem - these are the meristems located in the vascular and cork cambia in plants.
- Intercalary meristems - these are the meristems located at internodes, or stem regions between the places at which leaves attach, and leaf bases.
Result: There are 3 types of meristems.
The embedded proteins <u>allow specific substances to flow into the cell</u>.The phospholipid bilayer forms a stable barrier between two aqueous compartment.They embedded proteins carry the selective transportation of molecules and ensure their is cell to cell recognition.
The answer to this question would be labile.
A permanent cell is the one that will not divide after fully developed. This includes the heart and brain cells. That is why when these organs damaged there will be a permanent loss of function.
Stable cell only divides in some occasion. The example would be liver cells or kidney cells.
Answer:
A. to conserve soil nutrients
Explanation:
Crop rotation helps to maintain soil structure and nutrient levels. If you don't rotate crops, the soil in that field will inevitably begin to lose the nutrients plants need to grow.
