Cell plate is a structure found in certain types of cells in both plants and animals. It is formed during cytokinesis, which is the process by which a single cell divides into two daughter cells. The cell plate is made from a stack of new cell wall material which is secreted by the Golgi, and it is a key structure in the formation of the cell walls between the two daughter cells.
In plant cells, the cell plate grows during the process of cytokinesis and eventually gives rise to the cell walls, while in animals the cell walls are usually formed before the cell plate is formed during cytokinesis.

Are cell plates in animal cells?
Yes, cell plates are found in animal cells. Cell plates are structures found in the cell membrane of both plant and animal cells and are composed of proteins and lipids. In plant cells, cell plates are needed to form the cell walls.
In animal cells, these structures are involved in different processes, such as division and communicating with other cells. Cell plates are also important for maintaining the shape and integrity of the cell and for providing a protective barrier against the outside environment.
Do animal cells lack a cell plate?
No, animal cells do not lack a cell plate. A cell plate is a structure that forms when a cell divides. It is composed of proteins and lipids and is what divides the cytoplasm of a cell into two new cells.
In plant cells, the cell plate is formed first, and it divides the cell in two. In animal cells, however, the cytokinesis is much different. But rather a contractile ring that divides the cytoplasm. This process allows for more flexibility in the way animal cells divide compared to plant cells.
Additionally, the cell plate formed in plant cells is necessary for the formation of a cell wall. Because animal cells lack cell walls, there is no need for a cell plate to form.
Where does cell plate come from?
Cell plate is a membranous structure which is formed when two daughter cells divide from one parent cell during the process of cell division. During the process of cell division, the parent cell’s nucleus duplicates, producing two daughter nuclei, and the cytoplasm is separated into two equal parts.
The cell wall then contracts between these two daughter cells to form a cell plate, which serves as the separating line between the two new daughter cells. The cell plate is formed from a combination of the existing cell wall and newly-formed cytoplasm.
It is composed of microtubules, actin filaments and cell wall components, and helps ensure that the two daughter cells are separated from each other and stable after their division.
Which of the following is not found in an animal cell *?
A nucleus* is the only structure found in an animal cell that is not found in a plant cell. The nucleus is a membrane-bound organelle that contains the cell’s genetic material, including chromosomes, which allows the cell and organism to function.
The other structures found in both animal and plant cells are the endoplasmic reticulum, golgi apparatus, lysosomes, mitochondria, cytoplasm, vacuoles, and cell membrane.
Do animal cells have cell plates and no centrioles in cell division?
Yes, animal cells do have cell plates during cell division, but they do not have centrioles. Cell plates are components of the cell that form during the process of mitosis, when a cell divides. They are made up of proteins and lipids that are responsible for separating the chromosomes and keeping the cell in two during the process of cell division.
The purpose of cell plates is to create two new cells with identical genetic material and also to form the cell membrane of each daughter cell. Centrioles, on the other hand, are only found in the cells of certain organisms, such as Protozoa, and not in the cells of animals.
These organelles are responsible for assisting in the separation of the chromosomes during the process of cell division. Thus, animal cells do have cell plates during cell division, but lack centrioles.
What type of cell builds a cell plate?
A cell plate is formed by the assembly of microtubules and actin filaments in the cytoplasm of the cell. These microtubules and actin filaments are organized in a complex network of filaments and form a structural unit called the cytoskeleton.
The cytoskeleton allows for different parts of the cell to be organized and stabilized in a three dimensional arrangement. The cell plate is generally formed in the middle of the cell between the two daughter cells during the process of cell division.
The cell plate helps to organize the separation of the two new cells and gives them a distinct shape. During the assembly of the cell plate, the microtubules and actin filaments become tightly bundled by the protein myosin and form the contractile ring, which becomes known as the cleavage furrow.
This furrow helps to pinch the cell in half and separate the two daughter cells. The cell plate will eventually give rise to the new cell wall, which separates the daughter cells during the process of cytokinesis.
How is the cell plate formed quizlet?
The cell plate is a structure that is formed during cytokinesis, the process of cell division in eukaryotes. During the process, the cell membrane develops invaginations that eventually fuse together and form a complete structure between two daughter cells.
During the process of cell plate formation, microfilaments are involved and form a bridge that eventually divides the nucleus into two.
The cell plate is also formed by the deposition of vesicles containing components of the cell membrane such as lipids and proteins. These vesicles are generated by the Golgi apparatus and are secreted into the cytoplasm.
During the process, the lipids and proteins of the membrane move to the plasma membrane and form bridges between the two daughter cells. Eventually, the bridges fuse together and form a complete cell plate.
Once the cell plate is formed, it acts as a barrier to prevent further mixing of macromolecules between the two cells. The cell plate also plays a role in the separation of the cytoplasm in two distinct daughter cells.
The cell plate then breaks down as the cells further separate into two distinct entities.
