Can you observe any chloroplast in the onion cell using microscope?

No, you cannot observe chloroplasts in onion cells because onion cells do not contain chloroplasts. Onions belong to a group of plants known as monocots, which typically lack chloroplasts in their cells. Chloroplasts are mostly found in the cells of green plants that undergo photosynthesis.


What parts of the onion cells?

Those that you can see under the microscope are the cell wall, nucleus, nucleolus, and cytoplasm.


Are onion cells are prokaryotic or eukaryotic?

Onion cells are eukaryotic, meaning they have a true nucleus that houses their genetic material. Prokaryotic cells, like those found in bacteria, lack a true nucleus and other membrane-bound organelles.


How many chromosome in a originalcell compare to those in new cells formed by mitosis?

46 chromosome


Why does an onion not have ribosomes?

Onions do have ribosomes, as ribosomes are cellular organelles present in all living cells, including plant cells like those found in onions. Ribosomes are essential for protein synthesis, a process that occurs in all cells to create the proteins necessary for the cell to function.


Are centrioles found in onion cells?

Yes, centrioles are typically found in animal cells, while plant cells (including those from onions) do not typically contain centrioles. Plant cells rely on other structures within the cytoskeleton for organizing cell division.

How do the life functions of cells and organ systems compare?

cells are specialized for a specific function, they work together to make tissues. Those tissues work together to form organs. Those organs work together to form organ systems


What is the difference between an onion cell and a cheek cell?

Cheek cells are only found in animals, whereas onion cells are found in platns, particularly onion cells. Cheek cells, being animal cells, do not contain a cell wall as onion cells do becasue cell walls are found only in plant cells for structure and rigidness. Onion cells, unlike most plant cells, do not have chlorplasts becasue it does not need sunlight for photosynthesis as other plants do. Being grown underground, it receives nutrients directly from the soil, so chloraplasts are not evident. This is also why onions are never green, since chloroplasts contain chlorpohyll, a pigment which gives plants its green color. Basically, cheek cells are found in animals, and onion cells are found in plants.


What is the function of the cell membrane in an onion cell?

The onion cell, like any other plant cell, performs various functions necessary for the survival and growth of the plant. Here are some key functions of an onion cell: Structural Support: Onion cells provide structural support to the plant. They have a cell wall made of cellulose, which helps maintain the shape and rigidity of the cell. Storage: Onion cells can store nutrients and reserve materials in the form of starch granules or other storage compounds, ensuring a steady supply of energy for the plant. Photosynthesis: Onion cells contain chloroplasts, specialized organelles that perform photosynthesis. Chloroplasts capture light energy and convert it into chemical energy, producing sugars and oxygen. Water and Nutrient Absorption: Onion cells, particularly those in the root system, absorb water and essential nutrients from the soil through their cell membranes. This process allows the plant to take up the necessary substances for growth and metabolism. Transport: Onion cells are involved in the transport of water, minerals, and organic compounds throughout the plant. Xylem vessels within the cell walls transport water and minerals from the roots to the other parts of the plant, while phloem cells distribute sugars and other organic molecules to various plant tissues. Reproduction: Onion cells play a role in plant reproduction. They contain the necessary genetic material (DNA) that contributes to the formation of new onion plants through cell division and growth.
