Onions and Garlic
Garlic and onions are both from the same bulb genus Allium. Garlic can be traced back some 7,000 years to the ancient Egyptians. Both are used in a variety of food dishes and such as lasagne, bolonagise and French Onion Soup. The onion is found in three different colours; Yellow, red and white, whilst garlic is a white creamy colour. Both are said to have health benefits to humans. Garlic having antibacterial, antiviral, and antifungal properties whilst onions are thought to help with the common cold to heart disease, diabetes, osteoporosis, and other diseases.

Why the onions are important in the holes?
Onions are important in holes when planting certain crops because they act as natural pest repellents. Onions contain sulfur compounds that deter pests like aphids, carrot flies, and cabbage worms. By planting onions in the same holes as other crops, you can help protect them from potential insect damage, reducing the need for chemical pesticides. Additionally, onions can also help improve soil health by adding organic matter and nutrients as they decompose.
What is The pH of a pickled onion?
Well, honey, the pH of a pickled onion typically falls around 3.2 to 3.8, making it quite acidic. So if you're looking to add a tangy kick to your dish, these bad boys will do the trick. Just be sure to brush your teeth afterward unless you want to scare off your date with that acidic breath!
In Tagalog, scallion is called "sibuyas na mura." Now you can impress your friends with your newfound knowledge of green onions in Filipino. Just don't go around saying "sibuyas na mura" too loudly, or people might think you're talking about cheap onions!
What is the Tagalog word for leek?
The Tagalog word for leek is "sibuyas na mura." Leeks are a type of vegetable that belong to the Allium family, which also includes onions and garlic. They have a mild onion-like flavor and are commonly used in soups, stews, and other dishes in Filipino cuisine.
Where are the nucleoli of an onion cell found?
The nucleoli of an onion cell are found within the nucleus. The nucleus is a membrane-bound organelle that houses the cell's genetic material, including the nucleoli where ribosomal RNA synthesis takes place.
Why does onion DNA get extracted?
Onion DNA is extracted for various purposes such as genetic research, molecular biology experiments, and forensic analysis. By isolating and studying onion DNA, scientists can better understand the genetic makeup of onions and use this information to improve onion crops, develop new varieties, and study genetic traits.
The outermost layer of cells in an onion, the epidermis, forms a protective barrier against environmental stresses. The arrangement of cells in multiple layers allows for strength and flexibility, providing support to the parts underneath. Additionally, specialized cells called sclerenchyma cells provide extra structural support to the onion.
How do you propagate an onion?
Onion can be propagated either by seed, or from "sets" - tiny pearl-like onions produced on the stalk that comes up from a growing onion. Propagation from sets is much quicker. Full-sized yellow onions from seed to harvest are 110-120 days, a long-season crop.
Can a onion light a light bulb?
No i don't think so. I tried to cook an onion with the wires attached to the light bulb and it didn't power up but it would if you're using the stronger liquid rather than oils. Onion can only produce very little amount of energy.
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.
How is an onion cell specialised?
An onion cell is specialized for storage of nutrients. It has a large central vacuole that stores water and other molecules, while the cell wall provides structure and support. The outermost layer of the onion cell is specialized for protection against pathogens and physical damage.
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.
Which chemical makes an onion pungent?
The chemical that makes onions pungent is called syn-propanethial-S-oxide. When an onion is cut or crushed, enzymes react with sulfur compounds in the onion to produce this compound, which then stimulates our eyes to tear up and gives onions their characteristic smell and taste.
What does the onion bulb do for the onion?
The bulb stores all the energy needed to live through the cold of the winter. Think of it like storing fat for the winter. When it's ready to grow again the next season it uses that energy to regrow and set seed.
1. The cells of an onion skin are generally rectangular in shape and range in size from 0.25 to 0.4 millimeters in length (250-400 micrometers). A millimeter is abbreviated by mm and a micrometer by the Greek letter mu (12th letter of Greek alphabet) followed by an m:
millimeter
about 1/25th of an inch
micrometer
1/25,000th of an inch
Left: Microscopic view of an onion skin showing several rectangular cells, each with a small, spherical nucleus (red arrow). The slide was stained with a drop of yellowish-brown gram's iodine. Right: Highly magnified view of a cell from the meristematic root tip of an onion showing enlarged nucleus containing 16 chromosomes. The cell is in prophase of mitosis, with distinct chromosomes (chromosome doublets) and a disintegrating nuclear membrane.
Onion is a term used for many plants in the genus Allium. They are known by the common name "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 onion" but, used without qualifiers, it usually refers to Allium cepa.
Is cytoplasm visible in onion cells?
it is like a rectangular shape .nuclear nuclear can be seen under microscope
Why is there no chloroplast in the onion bulb?
Chloroplast is found in parts of plants exposed to sunlight, where it is used in photosynthesis. Onion bulbs are not normally exposed to sunlight, so there is no need for chloroplasts in the bulb.
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 is the effect of saltwater on onion cells?
If the concentration of salt is higher OUTSIDE the cell, then water will move from the cell to the outside (osmosis) to equilibrate the concentration gradient that you have created!
Water will leave the cell, and the cell will shrink (due to the decrease in volume).
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.
Why does an onion not have a cytoplasm?
All cells have cytoplasm, so yes, onion cells do have cytoplasm.
