Which lateral meristem is in part responsible for secondary growth?
vascular cambium
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.
Is lateral meristem a secondary growth?
In many vascular plants, secondary growth is the result of the activity of the two lateral meristems, the cork cambium and vascular cambium. Arising from lateral meristems, secondary growth increases the width of the plant root or stem, rather than its length.
What is the definition of lateral meristem?
Definition of lateral meristem : a meristem (as the cambium and cork cambium) that is arranged parallel to the sides of an organ and that is responsible for increase in diameter of the organ — compare apical meristem, intercalary meristem.
What are lateral meristem responsible for?
secondary growth
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.
Which meristem is responsible for the production of secondary tissue?
Thus, the correct answer is ‘Primary meristem. ‘
Which meristem tissue is responsible for secondary growth of 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 is a secondary meristem?
Definition of 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 of the following is responsible for production of secondary tissues a lateral meristem B cork cambium C Interfascicular meristem D All of the above?
Assertion: Fascicular vascular cambium, interfascicular cambium and cork-cambium are examples of lateral meristems. Reason: These are responsible for producing the secondary tissues.
What is lateral meristem and examples?
Lateral meristem is located along the sides of a part, as a stem or root. One of the two meristems in vascular plants (the cork cambium and the vascular (Fascicular) cambium) in which secondary growth occurs, resulting in increase in stem girth.
Is responsible for secondary growth?
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.
Which of the following is responsible for secondary growth?
So, the correct answer is ‘Vascular cambium’.
What is the difference between secondary meristem and lateral meristem?
There are two types of secondary meristems, these are also called the lateral meristems because they surround the established stem of a plant and cause it to grow laterally (i.e., larger in diameter). Vascular cambium, which produces secondary xylem and secondary phloem.
Which meristem is responsible for secondary growth of plant?
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.
What is the function of 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. Meristematic tissues may also be classified as either primary (derived directly from embryonic cells) or secondary (derived from permanent tissues).
What type of meristematic tissue is used in plants?
Plants use lateral meristem tissue to grow in diameter as part of secondary growth. There are two types of lateral meristematic tissue—the vascular cambium and the cork cambium.
What is the difference between apical and lateral meristem?
Growth at the apical meristem increases stem length and at the lateral meristem increases stem girth. Remember that all plant stem growth occurs at the meristems of the shoot system because this is where cell division occurs. There are two types of meristem in the plant stem: apical and lateral.
