In which of these cases will a ripe banana appear black?
A ripe banana will appear black when it has overripened and started to decay or when it has been exposed to extreme temperatures.
What causes the banana to turn brown in the refrigerator?
A banana will turn brown whether or not it is in a refrigerator. However, a banana will turn brown faster in a cold space, such as refrigerator, than if left in a space that is at room temperature.
The skin of a banana turns brown or black faster in a refrigerator, but the banana meat itself does not ripen that much more. In fact, it is recommended that ripened bananas be frozen to preserve them even longer. The cold temperature of a refrigerator encourages an enzyme (polyphenyl oxidase), which is naturally found in the banana, to polymerise phenols in the banana skin into polyphenols. Polyphenols are similar to melanin, the pigment responsible for the color in our skin. This is what blackens the skin of the bananas. Despite the color, the cold temperature will keep bananas firmer than a banana that has been left at room temperature for the same amount of time. The enzymes that break the starch into sugar, which makes the banana soft and ripe, work better at room temperature.
Does a banana conduct electricity?
Yes, a banana can conduct electricity. The high water content and minerals in a banana make it a good conductor of electricity. However, it is not as efficient a conductor as metals like copper.
Can you squeeze a banana and get juice?
No, bananas do not contain juice like citrus fruits. When squeezed, a banana would release mushy pulp, not juice.
To winterize a banana plant, prepare it by cutting back any damaged leaves and stems, then mulch the base of the plant with a thick layer of straw or leaves to protect it from frost. You can also wrap the plant in burlap or cover it with a frost cloth to provide additional insulation during the colder months. Water the plant sparingly, as it will require less water during the winter when it is dormant.
This is a question related to botany, and a good one. You need to now a little about living things and the scientific classification of them, for lack of better terminology, their roots or family tree. All living things fall into different categories in order to better determine their origins. Keeping this in mind, the categories from top to bottom are,: Kingdom, Order, Family, Genus, Species. Bananas are related to Turmeric, Cardamom and Ginger (considered distant cousins, much like a human family). I'll give you a rough breakdown.
Kingdom Plantae - They are all plants
Order Zingiberales - Still all the same
Family Zingiberaceae - Hmmm...Turmeric, Cardamom and Ginger all have the same
The banana Family is Musaceae and then everything else branches out from there.
So they all started from the same beginning but ended up with different families. Try to think of the way royalty works hence the very beginning listed as Kingdom. Hope it helps!
What ripens faster refrigerated bananas or room temperature bananas?
A banana will ripen and eventually rot faster at room temperature.

How can a combination of ipil-ipil leaves and banana can produce floor wax?
The combination of ipil-ipil leaves and banana can be used to produce floor wax through a process where the leaves are boiled to create a liquid extract, which is then mixed with mashed banana and other ingredients like beeswax or coconut oil. This mixture is then heated and stirred until a smooth consistency is achieved, creating a natural and eco-friendly floor wax product.
What is a banana ripening chamber?
A banana ripening chamber is a specially designed room or container that controls temperature, humidity, and airflow to accelerate the ripening process of bananas. It helps ensure that bananas reach the desired ripeness level before they are distributed to consumers.
The bananas all belong to the genus Musa in the family Musaceae.
More fully:
Kingdom: Plantae
Division: Magnoliophyta
Class: Liliopsida
Order: Zingiberales
Family: Musaceae
Genus: Musa
What unit do you use to measure the weight of a banana?
Yes it is because 1 kilogram equals 1000 grams
What is the banana growth process?
Bananas grow on large herbaceous plants that are native to tropical regions. The plants require plenty of sunlight, warmth, and water to thrive. The fruit start as flowers and develop into clusters of bananas that grow downward from the plant. Once the bananas reach maturity, they are harvested for consumption.
What is the chemical used to ripen bananas?
Ethylene gas is commonly used to ripen bananas. It is a natural plant hormone that triggers the ripening process by stimulating the production of enzymes responsible for fruit softening and color changes. Ethylene can be applied in controlled concentrations to accelerate the ripening of fruits like bananas.
No, the banana turning black is not a chemical reaction in the traditional sense. It is a natural process called enzymatic browning, where enzymes in the banana react with oxygen in the air, causing the fruit to darken. The change in color is due to the breakdown of pigments in the banana, not a chemical reaction.
Do bananas grow where it is cold?
Not naturally, no.
However it is possible to grow bananas in a cold country, as long as the growing environment is warm.
In Iceland, for example, bananas are grown in a large greenhouse.
The greenhouse is fed heat from pipes passing through it, which have hot spring water from the nearby volcanoes flowing through them, to heat the greenhouses.
What is the scientific name of banana tree?
The scientific name of the banana tree is Musa Acuminata.
What is the simple protocol for banana tissue culture?
in tissue culture should maintain some steps mandatory example explanting,surface sterilization, inoculation , incubation and subculture so their is no any simple protocol for tissue culture especially in banana need to take care still more than others plants because endogenous microbial contamination's will be more in succors so its better to follow specific protocol that should give healty plantlets free from diseases instead of going simple one.
Three bananas a day, every day, is probably too much even for an adult.
Bananas are a good source of potassium but too much can upset the sodium and potassium balance in the blood, leading to irregular heart beat and potential cardiac arrest. The kidneys normally eliminate excess sodium or potassium to keep things in balance.
Banana.com says a 9-inch banana contains about 900 mg of potassium, or about 100 mg per inch. The University of Maryland Medical Center (http://www.umm.edu/altmed/articles/potassium-000320.htm) lists the recommended daily intakes of dietary potassium are:
What are the stages of the ripening process of a banana?
Stage 1 - Hard and Green
This is how bananas are when freshly picked.
Stage 2 - Green with trace of yellow
The maturing process has begun, however there is still some time before they are ready to eat.
Stage 3 - More yellow than green
The ripening has begun in earnest and the fruit is now increasing its natural sugar content, the flesh is changing from the chalky hardness of under ripe fruit.
Stage 4 - Yellow with Green hint
That familiar creamy texture is developing now, and as the natural sugar content rises; the fruit is getting ready for eating.
Stage 5 - All yellow with green tip on crown
Ready to eat! The fruit is sweet, creamy and on the firmer side. Even though it is yummy, it still does not have its complete full sweet flavor.
Stage 6 - All yellow
At the peak of freshness now, and delicious to eat. The fruit is also starting to soften as it ages and is heading towards its top sugar content.
Stage 7 - Yellow with brown "sugar spots"
The sugar content is now at its peak; the flesh is perfect and has softened for easy mashing and blending.
See Sources and related links for pictures of the different stages.
From what I know, most monkeys peel the banana from the opposite end that we do, which would be the thin bump at the bottom of the banana.
Are there banana trees in the rainforest?
Banana plants, which are often referred to as banana trees even though they are technically herbs, can be found in tropical rainforests. They thrive in the warm and moist environment of the rainforest, where they can reach impressive heights and produce their fruit.
Why does a banana's skin look like it is still green while the inside is ripening?
A green banana is not a ripe banana. It is still edible, but it is not fully ripe, and it will eventually turn yellow and get sweeter and softer. Having said that, if bananas are exposed to cold temperatures for several hours the ripening process will be irreversibly stopped. This might explain why you can get bananas at the supermarket that are slightly green but will not ripen an further once you get them home. In all likelihood, they were exposed to prolonged cold temperatures during shipment and/or storage.
There are seven stages of ripeness. See Related questionsfor the different stages and the appearance of each stage.
What are the parts of a banana called?
A banana is a berry that grows on a tree. We consume the fruit of the banana tree, and is considered a major food staple in many countries as the caloric equivalent of a potato. The leaves are used in making baskets and in cooking as vessels.
Store bananas at what temperature?
Bananas should be stored at room temperature, ideally around 68-72°F (20-22°C). Placing them in a fruit bowl or hanging them in a banana hanger can help keep them fresh by allowing air to circulate around them. Avoid storing bananas in the refrigerator as this can cause them to turn black faster.
Can banana trees grow in Ghana?
Ghana grows so many bananas, the country could become a banana republic. (by the way - bananas are not trees, they are a large herbaceous plant and the upright stem is called a psudostem)
