What provides cells for secondary growth?

What provides cells for secondary growth?

Vascular cambium is lateral meristem that provides cells for secondary growth.

What is responsible for secondary growth in plants?

lateral meristem tissues
Plants’ secondary growth is controlled by the lateral meristem tissues. The activity of the lateral meristems, which are lacking in herbs and herbaceous plants, causes secondary growth of plants to increase stem thickness. The vascular cambium and cork are the two types of lateral tissues involved in secondary growth.

What cells are responsible for plant growth?

The key to plant growth is meristem, a type of plant tissue consisting of undifferentiated cells that can continue to divide and differentiate. Meristem allows plant stems and roots to grow longer (primary growth) and wider (secondary growth).

What meristem is responsible for secondary growth?

Lateral meristems
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 secondary tissues in plants?

Secondary tissues are produced in woody plants. This cylinder of meristematic tissue is the vascular cambium. The secondary xylem provides additional structural support and additional water conduction tissue in shrubs and trees. The secondary phloem replaces the primary phloem.

Which of the following tissues is secondary growth?

There are two types of lateral tissues involved in secondary growth, namely, vascular cambium and cork cambium.

What type of tissue is responsible for secondary growth?

cambium, plural Cambiums, orCambia, in plants, layer of actively dividing cells between xylem (wood) and phloem (bast) tissues that is responsible for the secondary growth of stems and roots (secondary growth occurs after the first season and results in increase in thickness).

How are secondary xylem and phloem formed?

Cell division by the cambium produces cells that become secondary xylem and phloem. As secondary phloem and xylem tissue accumulates, it both increases the girth of the stem and forms wood and bark. This increases the girth of the stem and additional vascular bundles differentiate within the secondary ground tissue.

Do Dicots undergo secondary growth?

Secondary growth occurs when dicot stems and roots grow wider. However, not all dicots that undergo secondary growth have woody stems—for example, tomato, carrot, and potato plants don’t have woody stems but they do undergo secondary growth. In general, monocots do not undergo secondary growth.

What produces secondary phloem?

The secondary phloem is a type of phloem that forms from the vascular cambium during the secondary growth. The vascular cambium is the meristematic tissue involved in this type of growth. Some of the cells produced by the vascular cambium may differentiate into secondary phloem (others as secondary xylem).

Which root tissue gives rise to secondary roots?

vascular cambium
In woody roots the vascular cambium (the lateral meristem that gives rise to secondary phloem and secondary xylem) originates in the pericycle as well as in the procambium; the procambium is the primary meristematic tissue between the primary phloem and…

Which plant tissue is responsible for longitudinal growth?

Answer: The key to plant growth is meristem, a type of plant tissue consisting of undifferentiated cells that can continue to divide and differentiate.
