Correct option is C
The correct answer is (c) phragmoplast.
· The phragmoplast is a plant cell structure that forms during late cytokinesis.
· It serves as a scaffold for cell plate assembly and subsequent formation of a new cell wall separating the two daughter cells.
· Cytokinesis in Plant Cells: During the final stages of mitosis and meiosis in plant cells, the phragmoplast forms between the two daughter nuclei.
· Role: Microtubules and actin filaments in the phragmoplast guide the vesicles containing cell wall materials to the center of the cell, where these vesicles fuse to form the cell plate.
· The cell plate eventually develops into the new cell wall.
Facts to remember:
·
Peristome refers to the structure around the mouth of a capsule in mosses and certain fungi, composed of tooth-like projections that aid in the release of spores.
· The
periplasm is the gel-like substance found between the inner cytoplasmic membrane and the outer membrane in gram-negative bacteria.
· A
protoplast is the living part of a plant or bacterial cell that includes the plasma membrane, cytoplasm, and all the organelles, but without the cell wall.
