26.Which of the following shows importance of mineral ion found in middle lamella of plant cells? A. Associated with the formation of bipolar spindle during cell division B. Essential for splitting of water during Photosynthesis C. Required for absorption and utilisation of calcium D. Maintenance of ribosomal constituents
Option A. Associated with the formation of bipolar spindle during cell division The middle lamella act as a cementing layer between the primary walls of surrounding cells. It is the cell wall's outermost layer of a matured plant cell. Calcium and magnesium pectates are components of the middle lamella. The middle lamella is referred to as a layer that joins the primary cell walls of two plant cells together. The primary structure is constructed up of cellulose-containing layers that are laid down by splitting and growing cells.
