Onion root tip cells generally cycle through the cell cycle in about 24 hours. This means that all the stages of the cell cycle, including interphase, mitosis, and cytokinesis, occur within this time frame. This rapid cell cycle allows for continuous growth and development of the onion root tip.
the onion root tip cell speands 90% of its time in interohase. interphase is the longest part of the cycle. it includes the G1 phase, the S phase, and the G2 phase.

What differences are between the onion root tip and whitefish embryo in size of the cells?
The cells in the onion root tip are typically smaller and more uniform in size compared to the cells in a whitefish embryo. Additionally, the onion root tip cells are actively dividing, while the whitefish embryo cells are undergoing differentiation and organ development.
Does an onion root have prokaryotic cells?
No, an onion root does not have prokaryotic cells. It is a plant organism, and like all plants, it contains eukaryotic cells. Eukaryotic cells have a true nucleus and other membrane-bound organelles, unlike prokaryotic cells.
Where in the onion plants are the green cells located?
The green cells in an onion plant are located in the leaves. These cells contain chlorophyll, which is responsible for photosynthesis and gives the leaves their green color.
In the onion root tip do the daughter cells occupy the same column of cells as the parent cell?
In the onion root tip, daughter cells do not occupy the same column of cells as the parent cell. Instead, they move away from the parent cell as they undergo cell division and growth. This process allows for the root to elongate and continue its growth.
How do scientist examine the tip of an onion root?
Scientists can examine the tip of an onion root by preparing a thin section with a microtome and staining it to make the cells visible under a microscope. They can then observe the different cell types in the root tip, such as root cap cells, meristematic cells, and elongating cells. This allows them to study the process of cell division and growth in the root tissue.
What cells are in an onion tip but not the onion?
The cells in an onion tip but not the onion itself are usually actively dividing cells located at the growing tip of the onion root, known as the root cap cells. These cells help protect the delicate meristematic cells responsible for root growth and can often be found in the root zone of plants.
Why would you not find a chloroplast in a onion root cell?
Onion root cells are typically from the underground parts of the plant, where they do not engage in photosynthesis. Chloroplasts, which are responsible for photosynthesis, are found in cells that are exposed to light, such as leaf cells. Therefore, you would not typically find chloroplasts in onion root cells.
What differences are between the onion root tip and whitefish embryo in size of the cells?
The cells in the onion root tip are typically smaller and more uniform in size compared to the cells in a whitefish embryo. Additionally, the onion root tip cells are actively dividing, while the whitefish embryo cells are undergoing differentiation and organ development.
Does an onion root have prokaryotic cells?
No, an onion root does not have prokaryotic cells. It is a plant organism, and like all plants, it contains eukaryotic cells. Eukaryotic cells have a true nucleus and other membrane-bound organelles, unlike prokaryotic cells.
What is the function of these epidermis onion cells?
The root cell's job is to gather minerals and and take it up the roots to the onion.
Do daughter cells occupy same column of cells as parent cells in onion?
Yes, daughter cells resulting from cell division in an onion root occupy the same column of cells as the parent cells. This organization helps maintain the overall structure and function of the root tissue.
What can you infer about the relative length of time an onion root tip call spends in each cell division?
Based on the onion root tip cells' stages in the cell cycle and relative lengths of the phases, you can infer that the cells spend the most time in the interphase stage, especially in the G1 phase. This is where the cells grow and perform normal functions before entering mitosis for a brief period of time.
Where in the onion plants are the green cells located?
The green cells in an onion plant are located in the leaves. These cells contain chlorophyll, which is responsible for photosynthesis and gives the leaves their green color.

What is the shape of onion root tip cells?
Onion root tip cells are typically rectangular in shape with a distinct rectangular nucleus located towards one end. They often have a clear central vacuole surrounded by a layer of cytoplasm and a cell wall.
What plant part of a plant does a onion come from?
the root the root No the root is below the ground and the green onion is above the ground which is a young onion. it will eventually grow into a onion.
