Lateral meristems are known as secondary meristems because they are responsible for secondary growth, or increase in stem girth and thickness. Meristems form anew from other cells in injured tissues and are responsible for wound healing. What are lateral meristems in plants?
tissue formation Secondary, or lateral, meristems, which are found in all woody plants and in some herbaceous ones, consist of the vascular cambium and the cork cambium. They produce secondary tissues from a ring of vascular cambium in stems and roots.

What are the two lateral meristems?

Lateral meristems include the vascular cambium and, in woody plants, the cork cambium (cambium is another term for meristem). 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 is the function of apical meristem?

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 lateral meristem also called?

Lateral meristem is present in between xylem and phloem (xylem and phloem together known as vascular bundle) therefore, lateral meristem is also called cambium.

Frequently Asked Questions(FAQ)

What do you mean by secondary meristem?

: a meristem that develops from cells that have differentiated and functioned as part of a mature tissue system and then become meristematic again — compare primary meristem.

Where is lateral meristem function?

Lateral Meristems – 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. The vascular cambium and the cork cambium are good examples of a lateral meristematic tissue.

Which is an example of secondary meristem?

A secondary meristem is a type of meristematic tissue that is responsible for the secondary growth in plants, i.e. growth in girth or thickness. … An example of a secondary meristem is the lateral meristem (e.g. cork cambium and accessory cambia).

What is primary lateral meristem?

The lateral meristem is a type of meristem that occurs at the lateral areas of the plant. Thus, it is responsible for the secondary growth of plant, i.e. the increase in girth. … The cork cambium, which gives rise to the periderm, is an example of a lateral meristem.

What is the example of apical meristem?

What are the type of lateral meristematic tissue?

There are two types of lateral meristematic tissue—the vascular cambium and the cork cambium.

Which is not a lateral meristem?

Thus the correct answer is Option (A) – Intercalary meristem. Note:- Once the tissue differentiates, it is no more capable of dividing.

What is primary meristem and secondary meristem?

Secondary meristems. It involved in the primary growth and thus it gives rise to the primary tissues of the plant. It involved in the secondary growth and thus it gives rise to the secondary tissues of the plant. It is responsible for a growth in length. It responsible for growth in term of thickness.

What is intercalary Meristematic?

: a meristem developing between regions of mature or permanent tissue (as at the base of the grass leaf) — compare apical meristem, lateral meristem.

What is the function of lateral?

The lateral line functions to detect vibrations and water movement and allows fish to orientate themselves in a water current (rheotaxis), gain information about their spatial environment, and also plays a vital role in schooling (see also HEARING AND LATERAL LINE | Lateral Line Structure).

How does intercalary meristem differ from lateral meristem?

The key difference between apical intercalary and lateral meristem is that the apical meristem situates at the tips of the roots and the shoots while the intercalary meristem situates at the internodes and lateral meristem locates at the lateral side of the stem and the roots.

What happens when you cut off the apical meristem?

If the apical meristem is cut off, the hormone stops flowing. This can trigger nodes along the stem or branch to grow new stems and branches to add height or length. Pruning can trigger certain hormones to send a message to meristems to grow new plant material.

What does Procambium produce?

The procambium produces vascular tissues. The primary xylem, fascicular cambium, and primary phloem arise from the procambium. The ground meristem produces the pith and cortex, which are ground tissues.

What is lateral tissue class 9?

2)lateral:Found beneath the bark(called cambium) and in vascular bundles of dicot root and stems. cambium is the region which is responsible for growth in thickness. It causes the stem or root to increase in diameter and girth(Secondary growth)

How are lateral roots formed?

Lateral roots are produced when cells in the pericycle, the layer of cells surrounding the central vascular cylinder, begin to divide, form additional cell layers that push through the outer cell layers of the primary root, and ultimately organize a second root meristem.

What is difference between primary and secondary growth?

The key difference between primary and secondary growth is that primary growth increases the length of roots and shoots as a result of cell division in the primary meristem while secondary growth increases the thickness or the girth of the plant as a result of cell division in the secondary meristem.

What is the function of lateral meristem Class 9?

Lateral meristem is responsible for increase in circumference i.e. girth of the stem or root of the plant.

What is lateral meristem according to class 9th?

Lateral Meristem It is located in the stems and roots on the lateral side. It increases the thickness of the plant. Vascular cambium and cork cambium are the two lateral meristems. These divide preclinically or radially and give rise to secondary permanent tissues.
