What is the Difference Between Primary and Secondary Meristem

The main difference between primary and secondary meristem is that primary meristem is derived from the promeristem whereas secondary meristem is derived from permanent tissues. Furthermore, primary meristem is involved in the primary growth while secondary meristem is involved in secondary growth.

What are primary and secondary meristem?

Meristems contribute to both primary (taller/longer) and secondary (wider) growth. Primary growth is controlled by root apical meristems or shoot apical meristems, while secondary growth is controlled by the two lateral meristems, called the vascular cambium and the cork cambium.

What is difference between primary and secondary growth?

The increase in length of the shoot and the root is referred to as primary growth. It is the result of cell division in the shoot apical meristem. Secondary growth is characterized by an increase in thickness or girth of the plant.

What are primary meristems?

A primary meristem is a type of meristematic tissue that is responsible for the primary growth. Primary growth is a growth in length. ... An example of a primary meristem is the apical meristem. Apical meristems are meristematic tissues located in the apices of plant, e.g. root apex and shoot apex.

What is 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.

Which is an example of secondary meristem?

Secondary Meristem: Secondary meristems are the meristematic tissue arises from the permanent tissues. Secondary meristems are usually lateral meristems and are responsible for the increase in thickness of the plant. Example: vascular cambium and cork cambium (phellogen).

What are primary and secondary roots?

What are the primary and secondary roots? Primary roots are the early roots in young plants that consist of taproots, basal roots, and lateral roots. Secondary roots are the side branches of the primary roots.

Can primary and secondary growth occur at the same time?

Yes primary and secondary growth occurs in same plant but not simultaneously. Primary growth occurs when the plants are young means the growth of roots and stems in length with the help of apical Meristem is primary growth.

What is the difference between primary and secondary phloem?

Primary phloem is produced from the apical meristem, which is a primary meristematic tissue, whereas secondary phloem is produced by vascular cambium, which is a secondary or lateral meristem.

Which meristem is responsible for secondary growth?

Apical meristems give rise to the primary plant body and are responsible for the extension of the roots and shoots. Lateral meristems are known as secondary meristems because they are responsible for secondary growth, or increase in stem girth and thickness.

Where are primary meristems found?

Primary meristems are found in the tips of the main and lateral shoots and roots, and hence they are called apical meristems. The apical meristems of the branches arise from the first shoot apical meristem, whereas the apical meristems of the secondary roots develop from the root endodermis.

What are the two types of meristems?

There are two types of apical meristem tissue: shoot apical meristem (SAM), which gives rise to organs like the leaves and flowers, and root apical meristem (RAM), which provides the meristematic cells for future root growth.

Which is not a primary meristem?

Ground tissue is a type of permanent tissue that performs the function of storing carbohydrates produced by the plant. It lies between the dermal tissue and vascular tissue and is also derived from the apical meristem. But it is not a primary meristem.
