What do you mean meristematic region?

What do you mean meristematic region?

a) The meristematic tissue is an area of active plant growth. Undifferentiated cells divide and form new, specialized cells. Meristematic tissue may be the cambium layer, leaf or flower buds, shoot tips, or root tips. Tissues produced by cell divisions of the vascular cambium are secondary tissues.

What is the structure and function of meristematic tissue?

Meristematic tissues contain living cells with varied shapes. The cells of the meristematic tissue divide actively to form specialized structures such as buds of leaves and flowers, tips of roots and shoots, etc. These cells help to increase the length and girth of the plant.

What is the function of apical meristematic tissue?

apical meristem, region of cells capable of division and growth in the root and shoot tips in plants. Apical meristems give rise to the primary plant body and are responsible for the extension of the roots and shoots.

What is the function of meristematic tissue for Class 7?

Meristematic tissue: Meristematic tissues are responsible for plant growth. They are present at the tips of roots,stem and branches. The cells present in these tissues constantly divide to produce new cells.

What is the function of intercalary meristematic tissue?

The meristematic tissues that are present at the base of internodes of stem and petioles of leaves are known as Intercalary meristem. The function of these tissues is to promote the growth of the plants by elongating the nodes and internodes present at the leaves and stems.

What are the locations and functions of meristems?

Meristems are of three types depending on their location. 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.

What is the function of the meristematic tissue and where is it located quizlet?

The meristematic tissue located at or near the tip of a stem or root that produces primary plant tissues and is responsible for increases in length (i.e., not secondary growth). Lateral meristematic tissue that produces the tough, protective periderm in seed plants. You just studied 21 terms!

What is the function of meristems where are they located quizlet?

Meristems are plant tissues in which cells divide to reproduce, grow, and develop new tissue. The most common meristems are apical (terminal) and lateral. All active meristems receive priority for the food materials and minerals available within the plant.

What does meristematic zone mean?

A meristematic zone forms a short distance outside the xylem, from which secondary tissue is developed both internally and externally; that to the inside contains both xylem and phloem elements.

What is the purpose of the meristematic zone?

Meristem Zones The apical meristem, also known as the “growing tip,” is an undifferentiated meristematic tissue found in the buds and growing tips of roots in plants. Its main function is to trigger the growth of new cells in young seedlings at the tips of roots and shoots and forming buds.

What are meristematic zone in roots?

The meristematic zone of a root is also known as its growing point. It is about 1mm in length. It is located partially within and partially behind the root cap in the sub-apical region. The cells in this zone show prominent nucleus and dense cytoplasm.
