37. Both animals and plant cells undergo cytokinesis after mitosis ends. How is the process and its outcome the same for both animals and plant cells? How is the process and its outcome different for animal and plant cells?
Due to the presence of a cell wall, cytokinesis in plant cells is significantly different from that in animal cells. Rather than forming a contractile ring, plant cells construct a cell plate in the middle of the cell. The Golgi apparatus releases vesicles containing cell wall materials. These vesicles fuse at the equatorial plane and form a cell plate. The cell plate begins as a fusion tube network, which then becomes a tubulo-vesicular network (TVN) as more components are added. The TVN develops into a tubular network, which then becomes a fenestrated sheet which adheres to the existing plasma membrane

In both animal and plant cells, cytokinesis is the process in which the cytoplasm divides and two daughter cells are formed after mitosis. This is the final stage of cell division and ensures that each daughter cell receives a copy of the genetic material.
The process and outcome of cytokinesis are similar in both animal and plant cells in that they both result in the formation of two daughter cells. However, there are significant differences in how this process occurs.
In animal cells, cytokinesis begins with the formation of a contractile ring made of actin and myosin proteins. This ring contracts and pinches the cytoplasm inwards, eventually forming a cleavage furrow that divides the cell into two. The furrow deepens until it reaches the midpoint of the cell, separating the cytoplasm and organelles into two daughter cells.
On the other hand, plant cells have a rigid cell wall that prevents the formation of a contractile ring. In plant cells, cytokinesis involves the construction of a cell plate. The Golgi apparatus releases vesicles containing cell wall materials, which fuse together at the equatorial plane of the cell. These fused vesicles form a cell plate that gradually expands outward until it reaches the cell walls, dividing the cytoplasm and organelles into two daughter cells.
The outcome of cytokinesis is also different in animal and plant cells due to their cell wall structure. In animal cells, the cell membrane is completely separated during cytokinesis, resulting in two separate daughter cells. In plant cells, however, the cell plate formed during cytokinesis eventually develops into a new cell wall that fuses with the existing cell walls, connecting the two daughter cells together.
In summary, both animal and plant cells undergo cytokinesis after mitosis, resulting in the formation of two daughter cells. However, the process and outcome of cytokinesis differ between animal and plant cells, primarily due to the presence of a cell wall in plant cells.
In both animal and plant cells, cytokinesis is the process that follows mitosis, where the cytoplasm of the cell divides to form two separate daughter cells. The outcome of cytokinesis is the completion of cell division, resulting in the formation of two genetically identical daughter cells.
However, the process of cytokinesis and its outcome differ between animal and plant cells due to the presence of a cell wall in plant cells.
In animal cells, cytokinesis begins with the formation of a contractile ring made up of actin and myosin filaments. These filaments contract, causing the plasma membrane to pinch inward, eventually forming a cleavage furrow. This furrow deepens until it reaches the center of the cell, dividing it into two separate cells.
In contrast, plant cells cannot form a contractile ring due to the rigid cell wall surrounding them. Instead, plant cells form a cell plate during cytokinesis. The Golgi apparatus releases vesicles containing cell wall materials into the middle of the cell. These vesicles fuse at the equatorial plane, forming a cell plate. Initially, the cell plate forms as a fusion tube network, which then becomes a tubulo-vesicular network. With the addition of more components, the tubulo-vesicular network develops into a tubular network and eventually transforms into a fenestrated sheet. This fenestrated sheet adheres to the existing plasma membrane, dividing the cell into two daughter cells. The cell wall then continues to develop and strengthen, completing the process of cytokinesis.
In summary, the outcome of cytokinesis is the same for both animal and plant cells - the formation of two daughter cells. However, the process of cytokinesis differs between the two cell types, with animal cells forming a contractile ring and undergoing furrow formation, while plant cells construct a cell plate through vesicle fusion and subsequent cell wall development.
