What does STOMA mean in BIOLOGY
Stoma, short for stomata, is a term used in plant biology to refer to the small pores in the epidermis of leaves and stems. These tiny openings control the exchange of gases, such as carbon dioxide and oxygen, between the inside and outside of the plant. Stomata also regulate water loss from leaves and other aerial organs. They essentially play an essential role in photosynthesis because they provide the necessary levels of CO2 for this process.
STOMA meaning in Biology in Academic & Science
STOMA mostly used in an acronym Biology in Category Academic & Science that means Any of the minute pores in the epidermis of the leaf or stem of a plant, forming a slit of variable width that allows movement of gases in and out of the intercellular spaces.
Shorthand: STOMA,
Full Form: Any of the minute pores in the epidermis of the leaf or stem of a plant, forming a slit of variable width that allows movement of gases in and out of the intercellular spaces.

What is a Stoma?
A stoma is any of the minute pores in the epidermis of the leaf or stem of a plant, forming a slit of variable width that allows movement of gases in and out of the intercellular spaces.
How does a Stoma work?
A stoma is an opening between cells that allows gases to move through them and into and out of the intercellular spaces. The gas exchange enables plants to take in carbon dioxide during photosynthesis and release oxygen as a waste product.
How many Stoma are on a plant?
The number of stomata depends on the species, but it can range from several hundred to over one million per square centimeter.
What is the main purpose of Stoma?
The primary function of stomata is gas exchange between plants and their environment; absorption of carbon dioxide for photosynthesis, as well as transpiration.
Does temperature affect Stoma activity?
Yes, temperature plays an important role in regulating stomatal movement – when temperatures are higher, plants tend to open their stomata for CO2 uptake and water loss by transpiration. When temperatures drop, plants close their stomata to conserve water vapor.
Are there other factors that influence Stoma activity?
Yes, light intensity, air humidity and air pressure all have an impact on stomatal aperture. As light intensity increases, so does stomatal aperture; therefore allowing greater rates of gas exchange. Similarly, low relative air humidity causes opening due to increased water loss by transpiration. High relative air humidity has an inhibitory effect on opening due to decreased water loss. Finally, high atmospheric pressure restricts opening while low atmospheric pressure leads to increased opening due to increased diffusion coefficient.
Are all plants equipped with Stomas?
All vascular land plants possess some type of epidermal openings or stomata for gas exchange between the atmosphere and leaf interior - ranging from mosses with few isolated pits scattered across their leaves' surface, up to monocotyledons possessing numerous small circular or linear structures along both sides of each vein bundle..
Final Words:
In conclusion, stomata are vital parts of most vascular plants – responsible for regulating both water loss through evaporation from leaf surfaces, and uptake of essential carbon dioxide necessary for conversion into sugars during photosynthesis processes. They are essential to life on Earth as we know it – without them our planet would be drastically different! All botanists should know what stomata stand for: essential gas passageways that enable carbon dioxide absorption required by all plant matter on Earth.
