What is the hypothesis of onion cell?
The hypothesis of observing onion cells under a microscope could be that the onion cells will have a distinct rectangular shape and contain a visible nucleus.
What are 2 organelles not visible in onion cell?
Two organelles not visible in an onion cell are the centrioles and lysosomes. Centrioles are involved in cell division and are not present in plant cells like onion cells. Lysosomes are membrane-bound organelles that contain digestive enzymes and are more commonly found in animal cells.
What parts of the cell were clearly visible in the onion root cells focused under hpo?
In onion root cells focused under high power magnification (hpo), the visible parts of the cell would include the nucleus, cell membrane, cytoplasm, and possibly cell walls. Depending on the specific staining technique or preparation method used, other organelles such as mitochondria, endoplasmic reticulum, and vacuoles may also be visible.
What parts of the onion cells are not found in the blood cells?
An onion cell has a cell wall and a large central vacuole, both of which are not present in mammalian blood cells. Additionally, onion cells have chloroplasts for photosynthesis, while blood cells do not contain chloroplasts.
What parts of a plant cell were clearly visible in the onion root cells focused under HPO?
Under high power objective (HPO) microscopy, several parts of the onion root cells are clearly visible, including the cell wall, which provides structure; the large central vacuole, which stores nutrients and waste; and the nucleus, often seen as a darker circular structure within the cell. Additionally, the cytoplasm can be observed, which contains various organelles. The overall rectangular shape of the cells is also evident due to the rigidity of the cell walls.
Describe how the onion and cheek cell were different in observed parts what parts did they have in common?
The Onion cell and cheek cell both had cytoplasm, nucleuses, and cell membranes under 400x Magnification
What is the hypothesis of onion cell?
The hypothesis of observing onion cells under a microscope could be that the onion cells will have a distinct rectangular shape and contain a visible nucleus.
What cell parts did you find in the onion cell but not in the cheek cells?
The onion cells are much more rectangle shaped, than the cheek cells and the nucleus in the onion cell is much more bigger and better seen in the microscope.
Why can you see the parts of a onion under a microsope?
You can see the parts of an onion under a microscope because onion cells are relatively large and have distinct cell structures, such as the cell wall, nucleus, and cytoplasm. The onion's transparent cell walls allow light to pass through, making it easier to observe the details. Additionally, when stained, the cells become more visible, highlighting various components under the microscope. This combination of size, transparency, and staining makes onion cells ideal for microscopic examination.
Why is iodine used when observing onion cells?
AnswerIodine was used to stain onion epidermal cells so you could see the cells more clearly and examine them. Naturally, the cell parts are difficult to see because they are clear.You put iodine on onion cells in order to make parts of the cell which were translucent, more visible. This is because iodine stains starch present in the onion cell.
What parts of the onion cells can identify?
nucleus, cytoplasm and cell membrane, and cell wall
What are 2 organelles not visible in onion cell?
Two organelles not visible in an onion cell are the centrioles and lysosomes. Centrioles are involved in cell division and are not present in plant cells like onion cells. Lysosomes are membrane-bound organelles that contain digestive enzymes and are more commonly found in animal cells.
Describe how the onion and cheek cell were similar in observed parts what parts did they have common?
Describe how the onion and cheek cell were similar in observed parts what parts did they have common? Well they are similar because they both have a nucleus and cytoplasm. They are different because in an onion cell there is a cell wall, doesnt have chlorplast, and it is a plant. For a cheek cell it has a cell membrane, doesnt have a cell wall, and is an animal.
What parts of the cell were clearly visible in the onion root cells focused under hpo?
In onion root cells focused under high power magnification (hpo), the visible parts of the cell would include the nucleus, cell membrane, cytoplasm, and possibly cell walls. Depending on the specific staining technique or preparation method used, other organelles such as mitochondria, endoplasmic reticulum, and vacuoles may also be visible.

An onion cell has a cell wall and a large central vacuole, both of which are not present in mammalian blood cells. Additionally, onion cells have chloroplasts for photosynthesis, while blood cells do not contain chloroplasts.
What does effect iodine have on the onion cells?
Iodine is often used to stain onion cells to make the cell structures more visible under a microscope. The iodine solution will stain specific cell components such as the cell walls and starch grains, allowing for easier observation and analysis of the cells.
What parts of the plant cell were clearly visible in the onion root cells under HPO?
Under high power objective (HPO) microscopy, the onion root cells typically display several clearly visible parts, including the cell wall, which provides structure and protection, and the large central vacuole that appears as a prominent clear space. The nucleus can also be observed, often stained and located near the cell wall. Additionally, the cytoplasm may be visible, containing various organelles, although details may vary based on the staining technique used.
