What is the function of the thylakoids in a plant cell?

What is the function of the thylakoids in a plant cell?

Thylakoids are the internal membranes of chloroplasts and cyanobacteria, and provide the platform for the light reactions of photosynthesis.

What is the main function of thylakoids?

The principal functions of thylakoids are the trapping of light energy and the transduction of this energy into the chemical energy forms, ATP and NADPH. During this process, water is oxidized and oxygen is released.

What are thylakoids and what are their functions?

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 are Thylakoid discs?

Thylakoids are membrane-bound compartments inside chloroplasts and cyanobacteria. They are the site of the light-dependent reactions of photosynthesis. Chloroplast thylakoids frequently form stacks of disks referred to as grana (singular: granum).

What is the function of thylakoid in photosynthesis?

Photosynthesis occurs in the chloroplasts where the photosynthetic membranes, the so-called thylakoids are located. They are responsible for the light reaction whereby light is captured and its energy converted to chemical energy in the form of ATP and NADPH concomitant with the development of oxygen.

Why are thylakoids important for photosynthesis?

Thylakoids are the epicenter for photosynthetic light-reactions. They contain the chlorophyll for the plant, which is the light-collecting pigment.

What are thylakoids what function do they have in photosynthesis quizlet?

A flattened membrane sac inside the chloroplast, used to convert light energy to chemical energy. Thylakoids often exist in stacks called grana that are interconnected; their membranes contain molecular “machinery” used to convert light energy to chemical energy.

Where are thylakoid discs?

the chloroplast
Thylakoids are flat, disk-like formations found in the chloroplast. They look similar to stacked coins. They’re responsible for ATP synthesis, water photolysis and are a component of an electron transport chain. They can also be found within cyanobacteria as well as in plant and algae chloroplasts.

Why is the thylakoid membrane important?

The major difference between chloroplasts and mitochondria, in terms of both structure and function, is the thylakoid membrane. This membrane is of central importance in chloroplasts, where it fills the role of the inner mitochondrial membrane in electron transport and the chemiosmotic generation of ATP (Figure 10.14).

What are thylakoids and their function in photosynthesis quizlet?

Thylakoids. A flattened membrane sac inside the chloroplast, used to convert light energy to chemical energy. Photosynthesis. The conversion of light energy to chemical energy that is stored in glucose or other organic compounds; occurs in plants, algae, and certain prokaryotes.

What happens in the thylakoid of a plant cell quizlet?

in the thylakoid membranes of chloroplasts, a cluster of chlorophyll and other pigment molecules that harvest light energy for the light reactions of photosynthesis. a biochemical pathway of photosynthesis in which carbon dioxide is converted into glucose using ATP.

What function do thylakoids have in photosynthesis?

What is the function of thylakoid in chloroplasts?

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.

Where does the word thylakoid come from and what does it mean?

The word thylakoid is from the Green word thylakos, which means pouch or sac. With the -oid ending, “thylakoid” means “pouch-like.” Thylakoids may also be called lamellae, although this term may be used to refer to the portion of a thylakoid that connects grana.

Which is part of the thylakoid membrane synthesizes ATP?

Thylakoids synthesize ATP using an ATP synthase enzyme that is similar to mitochondrial ATPase. The enzyme is integrated into the thylakoid membrane. The CF1-portion of the synthase molecule extended into the stroma, where ATP supports the light-independent photosynthesis reactions.

How is the chloroplast like a mitochondrion?

The structure of the chloroplast. In plants, chloroplast-containing cells exist in the mesophyll. Chloroplasts are surrounded by a double membrane similar to the double membrane found within a mitochondrion. Within the chloroplast is a third membrane that forms stacked, disc-shaped structures called thylakoids.
