Which cambium is responsible for secondary growth?
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 of the following is responsible for secondary growth?
Vascular cambium and cork cambium, also called secondary meristem, are responsible for secondary growth in plants. They increase the thickness of the plant body.
What is responsible for secondary growth?
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.
What is a secondary growth cambium?
The Vascular Cambium and Secondary Growth. The vascular cambium and cork cambium are secondary meristems that are formed in stems and roots after the tissues of the primary plant body have differentiated. The vascular cambium is responsible for increasing the diameter of stems and roots and for forming woody tissue.
What is secondary growth in simple words?
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.
What is secondary growth of plant?
The secondary growth of plants increase in stem thickness and it is due to the activity of the lateral meristems, which are absent in herbs or herbaceous plants. There are two types of lateral tissues involved in secondary growth, namely, vascular cambium and cork cambium.
What is the purpose of secondary growth and its function?
Secondary growth is the outward growth of the plant, making it thicker and wider. Secondary growth is important to woody plants because they grow much taller than other plants and need more support in their stems and roots. Lateral meristems are the dividing cells in secondary growth, and produce secondary tissues.Sep 13, 2021
Which cambium is responsible for secondary growth is present in this stem?
So, the correct answer is 'Vascular cambium'.
What is secondary growth in stem?
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.
In what part of a stem does secondary growth occur?
Secondary growth occurs at the lateral meristems. The cells at the meristems undergo cellular division, where each cell multiplies into two daughter cells and add to the cellular material collectively called tissue. Secondary growth in plants produces secondary phloem and xylem.Mar 28, 2022
