What is the Difference Between Phragmoplast and Cell Plate?
🆚 Go to Comparative Table 🆚The phragmoplast and cell plate are plant cell-specific structures involved in cell division and the formation of new cell walls. The main differences between them are:
- Structure and Composition: The phragmoplast is a complex arrangement of microtubules, microfilaments, Golgi-derived vesicles, and endoplasmic reticulum that gives rise to the cell plate during cytokinesis. The cell plate is a flattened, disk-shaped membrane-bound structure that serves as the precursor of the new cell wall.
- Function: The phragmoplast serves as a scaffold for cell plate assembly and subsequent formation of a new cell wall. The cell plate forms the cell wall that separates the two daughter cells.
- Formation: The phragmoplast is formed during the late stages of cytokinesis and only in Phragmoplastophyta, a clade that includes land plants and some algae. The cell plate is formed from the phragmoplast and is a common structure in terrestrial plants and some algae.
- Barrel-shaped vs. Flattened and Disk-shaped: The phragmoplast is barrel-shaped, while the cell plate is flattened and disk-shaped.
In summary, the phragmoplast is a complex arrangement of cellular components that serves as a scaffold for the formation of the cell plate, which is a membrane-bound structure that eventually develops into the cell wall separating the daughter cells.
Comparative Table: Phragmoplast vs Cell Plate
The phragmoplast and cell plate are both structures involved in plant cell division, specifically during cytokinesis. Here is a table comparing their differences:
Feature | Phragmoplast | Cell Plate |
---|---|---|
Definition | A complex microfilaments, Golgi-derived vesicles, and endoplasmic reticulum that gives rise to the cell plate. | A flattened membrane-bound structure that forms between two groups of daughter cells and serves as a precursor for the new cell wall. |
Shape | Barrel-shaped or cylindrical with two opposing arrays of actin filaments and microtubules. | Flattened and disk-shaped. |
Function | Serves as a scaffold for cell plate assembly and is crucial for proper targeting of Golgi and endosomal-derived vesicles. | Develops into the cell wall that separates two daughter cells. |
Formation | Arises from the fusion of small Golgi-derived vesicles that coalesce in the midzone of the phragmoplast. | Forms as a result of the fusion of Golgi and endosomal-derived vesicles. |
Location | Found only in phragmoplastophyta. | Common in terrestrial plants and some algae. |
In summary, the phragmoplast is a plant cell-specific structure that gives rise to the cell plate. The phragmoplast serves as a scaffold for cell plate assembly, while the cell plate works as a precursor for the new cell wall that separates the daughter cells during cytokinesis.
