What is a thylakoid in biology?
Definition of thylakoid : any of the membranous disks of lamellae within plant chloroplasts that are composed of protein and lipid and are the sites of the photochemical reactions of photosynthesis.
What are thylakoids and what is their role?
Thylakoids are the internal membranes of chloroplasts and cyanobacteria, and provide the platform for the light reactions of photosynthesis.
What is called thylakoid?
A thylakoid is a sheet-like membrane-bound structure that is the site of the light-dependent photosynthesis reactions in chloroplasts and cyanobacteria. It is the site that contains the chlorophyll used to absorb light and use it for biochemical reactions. With the -oid ending, “thylakoid” means “pouch-like.”
What is a thylakoid quizlet?
thylakoid. a membrane system found within chloroplasts that contains the components for photosynthesis. granum.
How do thylakoids work?
Thylakoids are tiny compartments found inside of chloroplasts. Their role is to help absorb sunlight in order for photosynthesis to occur. They contain all of the chlorophyll that the plant has which, in turn, allows for the absorption of sunlight.
What does the stroma do?
Stroma: The fluid of the chloroplast surrounding the thylakoid membrane; involved in the synthesis of organic molecules from carbon dioxide and water. Thylakoid: A flattened membrane sac inside the chloroplast, used to convert light energy to chemical energy.
What are thylakoids quizlet?
What are thylakoids, and how are they arranged?
Thylakoids are interconnected disc-like sacs of the internal membrane system of the chloroplast. They are found suspended in the stroma. Thylakoids are arranged in a stack, which is called grana . The thylakoid membrane contains the photosynthetic pigment chlorophyll, which absorbs the sunlight during photosynthesis.
What does thylakoid contain?
A thylakoid is a membrane-bound compartment inside chloroplasts and cyanobacteria . They are the site of the light-dependent reactions of photosynthesis. Thylakoids consist of a thylakoid membrane surrounding a thylakoid lumen.
What do thylakoids sacs contain?
The interior contains flattened sacs of photosynthetic membranes (thylakoids) formed by the invagination and fusion of the inner membrane. Thylakoids are usually arranged in stacks (grana) and contain the photosynthetic pigment (chlorophyll).
