Cells have the power of active division. Having large nuclei. Meristems MCQ (Multiple Choice Questions and Answers) Q1. 3. Nuclei are large. 3. 1. Characteristics of meristematic tissues : The cells of meristematic tissues are similar in structure and have thin and elastic primary cell walls made up of cellulose. Some cells produced by meristematic tissue stop dividing and acquire certain changes to become permanent tissues of the plant. Apical cell theory was given by Hofmeister Hanstein Haberlandt Grew Answer: 1 Q2. A group of cells which are similar in origin; similar in structure and similar in function are called simple permanent tissue. 3. 2. The characteristic features of meristmatic tissue are as follows : o The cells are structurally alike and are always living as well as thin-walled. Answer: Characteristics of meristematic tissues: (any four) 1. Characteristics of meristematic tissues: The cells of the meristematic tissue are similar in structure and have thin cellulose cell walls. Meristematic tissues or Meristems : The meristems are situated at the apices (tips) of the actively growing regions of the plants such as shoot apex and root apex. Cells are very small and isodiametric. Some cells produced by meristematic tissue stop dividing and acquire certain changes to become permanent tissues of the plant. There are two types of apical meristem tissue: shoot apical meristem (SAM), which gives rise to organs like the leaves and flowers, and root apical meristem (RAM), which provides the meristematic cells for future root growth.SAM and RAM cells divide rapidly and are considered indeterminate, in that they do not possess any defined end status. These are made up of many different types of cells. 2) They divide rapidly hence, there is no stored food in these cells. Cytoplasm is abundant. Meristem is a group of plant cells that remain in a continuous state of division. Characteristics of meristematic tissues : The cells of meristematic tissues are similar in structure and have thin and elastic primary cell walls made up of cellulose. This change from meristematic to permanent tissue is called differentiation. A group of cells which are The characteristics of the transparent and white tissue induced from the surface of the cell layer differed slightly depending on the composition of the hormones (with the exceptions of T12, T14, T15, and T16). It is formed as a result of division and differentiation of meristematic tissue. CMCs were induced within 4 to 7 days of culturing in media … A meristematic tissue constitutes a group of actively dividing cells present in the growing region of plant, e.g., the tips of roots and stems. Consists of small, cubodial densely packed cells with thin cell walls & large nuclei, which keeps on dividing to form new cells. 5. please show this pic 1 See answer jatin2892 is waiting for your help. They are made up of immature cells. The word “Meristem” originated from “Meristos” (Greek = continuous division) and the term meristem was introduced by Nageli (1858). These tissues in a plant comprise small, densely packed cells that can keep dividing to form new cells. Cells are small in size. Main characteristics of Meristematic tissue. 4. The following are the characteristics of the meristematic cells. Characteristics of meristematic tissues.
