Onion cells do not contain chloroplasts, as they are non-photosynthetic and do not perform photosynthesis. Instead, they primarily serve as storage and structural support. Chloroplasts are typically found in green plant tissues that are exposed to sunlight, which is not the case for the underground bulbs of onions.
What else can I help you with?
Which of the 2 cells cheek or onion cells have a regular arrangement and structure?
Between the 2 cells that are cheek and onion cells, the one that has a regular arrangement and structure are onion cells. Cheek cells have an irregular shape.
What structure is found in elodea and not in potato and union cells?
The structure found in Elodea cells but not in potato and onion cells is the chloroplast. Chloroplasts are responsible for photosynthesis, which is the process of converting light energy into chemical energy to produce glucose. In Elodea, chloroplasts are abundant due to its aquatic environment, whereas in potato and onion cells, chloroplasts are less prevalent.
Where are onion cells found?
All organisms are made of cells. An onion is and organism, hence all parts of an onion are made of cells.
How does the structure of an onion skin cell differ from other plant cells?
The structure of an onion skin cell differs from other plant cells in that it lacks chloroplasts, which are responsible for photosynthesis. Onion skin cells also have a unique rectangular shape and a thin cell wall compared to other plant cells.
What is the structure and function of onion cells in plant biology?
The structure of onion cells consists of a cell wall, cell membrane, cytoplasm, and a large central vacuole. The function of onion cells is to store nutrients, provide structural support, and regulate water balance within the plant.
Where can you find onion epidermal cells and what is their significance in plant biology?
Onion epidermal cells can be found in the thin, transparent layer on the surface of an onion bulb. These cells are significant in plant biology because they are commonly used in science experiments to study cell structure, division, and function. They are also used to observe processes such as osmosis and plasmolysis.
Where can you find onion epidermal cells?
Onion epidermal cells can be found on the outer layer of an onion bulb, specifically in the thin, transparent skin that covers the onion. This layer serves as a protective barrier for the bulb and is often used in biology labs for microscopic studies due to its easy accessibility and clear cell structure. To observe these cells, you can peel off a small section of the onion's skin and place it on a microscope slide.
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.
What structure you seen in hydrilla leaf cell but in onion cell?
The structures that are found in the hydrilla which are not found in the onion cell are chloroplasts, specifically the stomata and chlorophyll. Onions lack these structures because they grow underground.
Why onion is used to see the structure of a plant cell?
because it has plant cells
What is one organelle found in onion cells that is not found in eubacteria cell?
Lexor
What structure can be seen in Elodea leaf but not present in epidermal cells of onion cells?
Chloroplasts can be seen in Elodea leaf cells but not in the epidermal cells of onion cells. Chloroplasts are responsible for photosynthesis in plant cells, containing chlorophyll that captures sunlight for energy production. Onion epidermal cells do not contain chloroplasts as they do not perform photosynthesis.
