What organelles do you see under microscope?
Note: The nucleus, cytoplasm, cell membrane, chloroplasts and cell wall are organelles which can be seen under a light microscope.
What organelle do you think would be the easiest to see inside an onion cell?
The easiest cellular structure to see is the cytoskeleton by proxy of the cytoplasm. The cytoplasm forms the largest portion of the cell, it can be easily identified as the space between all the other organelles, and it is universally present in all cells.
What type of cell is onion cell?
The onion cell is a plant cell that can be obtained by peeling off an onion. Onion cells exhibit a brick-like shape under the microscope. It has a cell wall, cell membrane, cytoplasm, nucleus, and a large vacuole. At the periphery of the cytoplasm, the nucleus is present.
Do onion epithelial cells have ribosomes?
To answer your question, onion cells (you usually use epithelial cells for this experiment) are ‘normal’ cells with all of the ‘normal’ organelles: nucleus, cytoplasm, cell wall and membrane, mitochondria, ribosomes, rough and smooth endoplasmic reticulum, centrioles, Golgi body and vacuoles.
How are onion cells formed under microscope?
Onion Cells Under a Microscope Requirements, Preparation and Observation. The bulb of an onion is formed from modified leaves. While photosynthesis takes place in the leaves of an onion containing chloroplast, the little glucose that is produced from this process is converted in to starch (starch granules) and stored in the bulb.
What organelles are found in onion cells?
In your case, this would just be the nucleus, the cell membrane and the cell wall. To answer your question, onion cells (you usually use epithelial cells for this experiment) are ‘normal’ cells with all of the ‘normal’ organelles: nucleus, cytoplasm, cell wall and membrane, mitochondria, ribosomes, rough and smooth endoplasmic reticulum,…
Why is iodine used to stain onion cells?
Iodine – to stain the cells so it can be seen under the microscope. Not all cells can be stained with iodine, but onion cells take it up nicely so that there is contrast under the microscope. Onion – Peeled to one layer. If it’s any thicker, you won’t be able to see through it under the microscope.
What can you learn about cell tissues from an onion peel?
Studying cell tissues from an onion peel is a great exercise in using light microscopes and learning about plant cells, since onion cells are highly visible under a microscope, especially when stained correctly. Onions are multicellular plant organisms, which basically means that they are made up of many cells that are uniform in size and shape.
