Thylakoid - Wikipedia
Thylakoids are membrane-bound compartments 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. Chloroplast thylakoids frequently form stacks of disks referred to as grana (singular: granum).
Thylakoid Definition and Function - ThoughtCo
2019年10月3日 · 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.
10.2: The structure of the chloroplast - Biology LibreTexts
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.

2024年10月30日 · A third, internal membrane, extensively folded and characterized by the presence of closed disks (or thylakoids), is known as the thylakoid membrane. In most higher plants, the thylakoids are arranged in tight stacks called grana (singular granum).
10.4: The Light-Dependent Reactions - Biology LibreTexts
In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water. The light-dependent reactions release oxygen as a byproduct as water is broken apart.
What is the function of Thylakoid? - BYJU'S
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.

…presence of closed disks (or thylakoids), is known as the thylakoid membrane. In most higher plants, the thylakoids are arranged in tight stacks called grana (singular granum). Grana are connected by stromal lamellae, extensions that run from one granum, through the stroma, into a neighbouring granum .
