Which tissue are responsible for secondary growth of plant in Class 9?
Vascular cambium and cork cambium, also called secondary meristem, are responsible for secondary growth in plants. They increase the thickness of the plant body.
Which tissue are responsible for the secondary growth in plants?
The process of secondary growth is controlled by the lateral meristems, and is similar in both stems and roots. Lateral meristems include the vascular cambium and, in woody plants, the cork cambium (cambium is another term for meristem).
What is responsible for secondary growth in stems?
Cambium is the layer of actively dividing cells between xylem and phloem tissues that is responsible for the secondary growth of stems and roots. The cambium produces new layers of phloem on the outside and of xylem on the inside, thus increasing the diameter of the stem.
Which meristem is responsible for secondary growth?
Lateral Meristems Responsible for Secondary Growth of the Monocotyledons: A Survey of the State of the Art - PMC.Apr 4, 2015
What type of meristem is responsible for secondary growth?
The lateral meristem tissues are responsible for the secondary growth of plants.
Which meristem is responsible for primary 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.
What is secondary growth responsible for?
Arising from lateral meristems, secondary growth increases the girth of the plant root or stem, rather than its length. As long as the lateral meristems continue to produce new cells, the stem or root will continue to grow in diameter.
Which meristem is responsible for the growth of secondary xylem in trees?
Apical meristems are at the tips of branches and are associated with primary growth, while two lateral meristems are located within the stem and are associated with secondary growth. The vascular cambium is the lateral meristem that increases vascular tissue in the plant (secondary phloem and xylem).Mar 28, 2022
What is primary and secondary growth Class 9?
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. It is caused by cell division in the lateral meristem.Jun 8, 2022
What is primary and secondary growth?
The increase in length of the shoot and the root is referred to as primary growth , and 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, and is caused by cell division in the lateral meristem.
What is secondary growth Short answer?
In botany, secondary growth is the growth that results from cell division in the cambia or lateral meristems and that causes the stems and roots to thicken, while primary growth is growth that occurs as a result of cell division at the tips of stems and roots, causing them to elongate, and gives rise to primary tissue.
