What are the main features of meristematic cells?
The cells are isodiametric with thin cellulosic cell walls with no secondary cell wall.
What are the main features of meristematic cells Why do these cells need to have a high mitotic rate?
Meristematic cells have very thin cell walls small vacuoles a well-centralized nucleus and they are constantly undergoing mitosis. Meristematic cells need a high mitotic rate because they are responsible for the plant growth.
What is the function of meristem cells in plants?
Meristems at the tips of roots provide a constant supply of new cells allowing roots to grow longer. Meristems at the tips of shoots allow a plant to keep growing taller and spread wider. Meristems between the xylem and phloem increase the width of a plant. These result in the annual growth rings in trees.

What are the characteristics of meristematic tissue class 9?
What are meristematic tissues Class 9?
Meristematic tissue. It is responsible for growth of plant. Meristematic tissue has the ability to divide and redivide to provide growth to plants. Generally, growth of plants occurs from specific region like root and shoot, nodes, girth of stem, leaf base etc. Therefore, meristematic tissue is present in these regions …
What are the two special features of the meristematic tissues?
Meristematic tissue has a number of defining features, including small cells, thin cell walls, large cell nuclei, absent or small vacuoles, and no intercellular spaces.
Which of the following is not a feature of meristematic cells?
the correct option is ‘Absence of reserve food’.
How many given features are related to meristematic tissue?
The four main characteristics Of Meristematic Tissue are: These tissues have the quality of self-renewal. These tissues comprise very small and few vacuoles. Meristematic tissue possess a single, large and prominent nucleus.
Which of the following feature is exhibited by the cells in the region of meristematic activity?
So, the correct answer is ‘Thin wall, dense protoplasm, no intercellular spaces, isodiametric and nucleate’.
Which is not a feature of meristematic cell?
Which of the following examples have all the features belong to meristematic cells?
Explanation: Meristematic cells are actively dividing cells responsible for primary and secondary growth in plants, e.g. apical meristem, intercalary meristem and lateral meristem. These cells are compactly arranged isodiametric cells with thin cellulosic cell walls. They do not have intercellular spaces.
Which of the following features are found in cells of meristematic tissues in plants?
The correct answer is Cell active with dense cytoplasm, thin cellulose walls, and prominent nuclei. Plant Meristematic tissues are active cells or groups of active cells that have the ability to divide.
Which of the following feature is absent in cells of meristematic tissue?
