What is stroma simple words?
1 : the supporting framework of an animal organ typically consisting of connective tissue. 2 : the spongy protoplasmic framework of some cells (as a red blood cell) Other Words from stroma. stromal \ -məl \ adjective.
What is the stroma function?
The main function of stroma cells is to help support organs and act as connective tissue for particular organs. The connective tissue here connects to the parenchyma cells of things such as blood vessels and nerves. The stroma cells will help to reduce stress over the organ.
How do you explain chloroplasts to children?
Chloroplasts are small organelles inside the cells of plants and algae. They absorb light to make sugar in a process called photosynthesis. The sugar can be stored in the form of starch. Chloroplasts contain the molecule chlorophyll, which absorbs sunlight for photosynthesis.
What happens in the stroma in photosynthesis?
The light-independent reactions of photosynthesis take place within the stroma. It contains enzymes that work with ATP and NADPH to “fix” carbon from carbon dioxide into molecules that can be used to build glucose. The chloroplast’s own genetic material (separate from that of the cell) is also stored in the stroma.
What is the importance of the stroma of the chloroplast?
The stroma is essential for this because not only does it contain the enzymes necessary for carbon fixation, it also manages the chloroplast response to cellular stresses and signaling between various organelles. It plays an important role in both the light-dependent and light-independent reactions of photosynthesis.
What is stroma tissue?
Stroma is the connective tissue just below the surface of an organ. It is a special type of tissue that helps hold the other parts of the organ together. Stroma is made up of cells that give the tissue its strength and shape.
Where is the stroma located in a chloroplast?
The green pigment chlorophyll is located within the thylakoid membrane, and the space between the thylakoid and the chloroplast membranes is called the stroma (Figure 3, Figure 4).
What is chloroplast made of for kids?
Chloroplasts contain the following ‘ingredients’: proteins, chlorophyll, carbohydrates, carotenoids, ribosomes, lipids, DNA, RNA, enzymes and co-enzymes. These are all essential for photosynthesis. 5. The outer membrane, inner membrane and the intermembrane space are collectively called the ‘chloroplast envelope’.
What is a stroma in biology?
stroma. / (ˈstrəʊmə) / noun plural -mata (-mətə) biology. the gel-like matrix of chloroplasts and certain cells. the fibrous connective tissue forming the matrix of the mammalian ovary and testis.
What does the stroma of the chloroplast contain quizlet?
-The stroma contains the enzymes and a suitable pH for the Calvin cycle to occur. -Contain lipid droplets which can be used in making the phospholipid bilayer of the inner and outer membrane of the chloroplast. -Photosynthetic pigments are arranged in photosystems to allow maximum absorption of light energy.
What does stroma mean in science?
noun, plural stro·ma·ta [stroh-muh-tuh]. Cell Biology. the supporting framework or matrix of a cell. Anatomy. the supporting framework, usually of connective tissue, of an organ, as distinguished from the parenchyma.
