Does a onion cell have a Cell membrane?
Yes, an onion cell has a cell membrane. The cell membrane is a thin, flexible barrier that surrounds the cell and controls what enters and exits the cell. It is essential for maintaining the cell's integrity and regulating its internal environment.
What are the parts of the onion cell you identified?
Onion is a term used for many plants in the genus Allium. They are known by the common name "onion" but, used without qualifiers, it usually refers to Allium cepa.[1] Allium cepa is also known as the "garden onion" or "bulb" onion. Above ground, the onion shows only a single vertical shoot; the bulb grows underground, and is used for energy storage, leading to the possibility of confusion with a tuber, which it is not.[2] It is a close relative to garlic.Allium cepa is known only in cultivation,[3] but related wild species occur in Central Asia. The most closely related species include Allium vavilovii (Popov & Vved.) and Allium asarense (R.M. Fritsch & Matin) from Iran.[4] However, Zohary and Hopf warn that "there are doubts whether the A. vavilovii collections tested represent genuine wild material or only feral derivatives of the crop."[5]
How do you prepare onion cells slides?
add ethanol onto the thin cell layer on the slide and watch under a microscope. the cell membrane moves away from the cell wall as the cell is becoming plasmolized and the red dye of the onion cell spreads as there is no longer a membrane to contain it
How much does one onion weigh in ounces?

Why are the onion root tip and the whitefish blastula useful tissue for the study of cell division?
Root tips of allium cepa (otherwise known as the onion) are popularly used for cytological studies all over the world for the following reasons: 1) Roots are easy to grow from the base of the bulb kept over a water container. 2) Good quality, unsoiled root tips are easy to obtain. 3) Root tips have very rapid rate of mitosis. 4) The cells are very responsive to staining techniques. 5) The chromosomes are large and fewer in number. (Only 16 in a cell have the diploid condition. 8 is the haploid number.) 6) Fixing, staining, and ultimately making the slides permanent is easy in this material.

How much dried onion equals 1 cup chopped?

Why the purple and white pikmins don't have onions?
They come from candypop buds. (the flower things) There is no known onion for them. Maybe it will be found in pikmin 3, but currently they don't have an onion because it hasn't been found yet. If you're wondering why the designers made it that way, then I have no idea. By the way, pikmin is already plural.
Is the chloroplast in onion cells larger than the nuclei?
No, the nuclei in onion cells are generally larger than the chloroplasts. Nuclei are the control center of the cell and contain genetic material, while chloroplasts are responsible for photosynthesis.
