A "stoma" is singular, whereas "stomata" is plural.
Each guard cell is surrounded by two guard cells which are specialized parenchyma cells.
Imagine that the guard cells are like two longish, curved balloons tied together at each end. (Each guard cell is like one of these balloons). If the balloons are both filled with air, they curve away from each other, creating a hole in the middle (a stoma). However, if the two balloons are not filled with air, they are pressed tightly together. (Guard cells are pressed tightly together by the surrounding parenchyma cells).
During the day, sunlight causes the chloroplasts within the guard cells to produce sugar. (Guard cells contain more chloroplasts than surrounding parenchyma cells). Sugar builds up within the guard cells. By osmosis, water is drawn into the guard cells from the surrounding parenchyma cells, causing the guard cells to swell and close the stomata. This prevents water loss from the leaf during the heat of the day.
At night, the sugar is used up, the water within the guard cells passes out of the guard cells, and the stomata open for transpiration and gas exchange: Carbon dioxide, oxygen and water vapour pass in and out of the leaves through the stomata. (Most stomata are found on the leaves of most plants, though cactus have them on their stems - because the leaves of cactus are the needles).
What else can I help you with?
The enzyme-rich solution found within the chloroplast is called the?
The enzyme-rich solution found within the chloroplast is called the stroma. It contains enzymes essential for the process of photosynthesis, allowing the chloroplast to carry out its function of capturing light energy and converting it into chemical energy.
Which part of a chloroplast does the Calvin.cycle occur in?
The stroma
In what part of chloroplast does glucose production occur?
It is the stroma. It is the chloroplast cytoplasm
What is the region outside the chloroplast?
The region outside the chloroplast is called the cytoplasm. It is a gel-like substance that fills the cell and contains various organelles, including the mitochondria, endoplasmic reticulum, and ribosomes. The cytoplasm plays a key role in supporting various cellular processes, such as protein synthesis and energy production.
In what part of a chloroplast does Calvin cycle occur?
It is the cytoplasm of chloroplast. It is called as stroma

The enzyme-rich solution found within the chloroplast is called the stroma. It contains enzymes essential for the process of photosynthesis, allowing the chloroplast to carry out its function of capturing light energy and converting it into chemical energy.
What are the spaces between the gran in chloroplasts called?
We call it stoma. the space between grana.
Which part of a chloroplast does the Calvin.cycle occur in?
The stroma
What is the region of the chloroplast in which the Calvin cylcle occurs in?
It takes place in the stroma. Stroma is like cytoplasm of chloroplast
In what part of chloroplast does glucose production occur?
It is the stroma. It is the chloroplast cytoplasm
What is the jelly inside chloroplast?
It is the cytoplasm of chloroplast.It is called stroma.
What is the region outside the chloroplast?
The region outside the chloroplast is called the cytoplasm. It is a gel-like substance that fills the cell and contains various organelles, including the mitochondria, endoplasmic reticulum, and ribosomes. The cytoplasm plays a key role in supporting various cellular processes, such as protein synthesis and energy production.
In what part of a chloroplast does Calvin cycle occur?
It is the cytoplasm of chloroplast. It is called as stroma
What are the Spaces between grana called?
The spaces between grana in a chloroplast are called stroma. Stroma is where the enzymes for the light-independent reactions of photosynthesis are located.
What are the spaces between the grana in chloroplast called?
They are called stroma.
What is the fluid portion of the chloroplast that is located outside the thylakoids called?
It is called the stroma. It is like the cytoplasm
Where is the stroma in the plant?
The stroma is located within the chloroplasts of plant cells. It surrounds the thylakoid membranes where the light-dependent reactions of photosynthesis occur, and is the site where the Calvin Cycle, the light-independent reactions, take place.
