write a short note on meristematic tissue with their location and function in plants along with their diagram
Answers
Answer:
Meristematic tissues are simple living tissues having thin wall compactly arranged cells. These cells are capable of division and formation of new cells.
There are three kinds of meristematic tissues:
* Apical Meristem [present at the tips of roots and stems]
* Interclary Meristem [present at the base of leaf and internode]
* Lateral Meristem [present at lateral side of tree]
Functions of meristematic tissue
Thin cell wall.
Intercellular spaces are present.
Dense cytoplasm and prominent nucleus.
Large number of cell organalles are present.
Vacuoles are generally absent.
Actively dividing cells are present in growing region of plants that is root and shoot tip.
Meristems are specialised regions of plant growth. The meristems mark the regions where active cell division and rapid division of cells take place. Meristems are of three types depending on their location.
Apical meristem:
It is present at the root apex and the shoot apex. The shoot apical meristem is present at the tip of the shoots and its active division results in the elongation of the stem and formation of new leaves. The root apical meristem helps in root elongation.
Intercalary meristem:
The intercalary meristems are located at the internodes or the base of the leaves. The intercalary meristems help in increasing the length of the internode. This is usually seen in monocotyledonous plants.
Lateral meristem:
The lateral meristems are present on the lateral side of the stem and root of a plant. These meristems help in increasing the thickness of the plants.
