FAQs on Collenchyma: Permanent Tissues Video Lecture - Biology Class 11 - NEET

1. What is the function of collenchyma in plants?
Ans. Collenchyma is a type of permanent tissue in plants that provides mechanical support to growing parts of the plant. It helps in maintaining the shape and structure of the plant, especially in areas where growth is still occurring.
2. How is collenchyma different from other types of plant tissues?
Ans. Collenchyma differs from other plant tissues, such as parenchyma and sclerenchyma, in terms of cell wall thickness and flexibility. Collenchyma cells have thickened cell walls, particularly at the corners, which provide extra strength and support to the plant.
3. Where is collenchyma tissue found in plants?
Ans. Collenchyma tissue is primarily found in the stem and petioles of plants. It is commonly found below the epidermis, providing support to young, growing parts of the plant.
4. What are the different types of collenchyma cells?
Ans. There are three types of collenchyma cells: angular, tangential, and lacunar. Angular collenchyma cells have thickened cell walls at the corners, tangential collenchyma cells have thickened cell walls along the tangential walls, and lacunar collenchyma cells have large intercellular spaces.
5. Can collenchyma tissue undergo cell division?
Ans. No, collenchyma tissue cannot undergo cell division as it is a permanent tissue. Once the cells of collenchyma tissue are formed, they do not divide further. However, they can elongate and expand to accommodate the growth of the plant.
