A chloroplast has 3 main components. They are the envelope, stroma and?
- A
Thylakoid
- B
F1 particles
- C
Granum
- D
Centrosome
Chloroplasts are split into 3 parts, the envelope, stroma and thylakoid. The thylakoid is the site of light-dependent photosynthesis reactions.
A chloroplast is split into 3 parts: the envelope, stroma and thylakoid. Thylakoid is the site of light dependent reactions of photosynthesis.
F1 particles are present in the inner mitochondrial space of the mitochondrion. It is attached on the infoldings called the cristae. F1 particles are also known as oxysomes or elementary particles or F1−F0 particles. They are responsible for ATP synthesis and oxidation.
A granum is a stack of thylakoid membranes within the chloroplast that contains chlorophyll and other pigments. These structures increase the surface area for light-dependent reactions of photosynthesis. Thylakoids within a granum are connected by stroma thylakoids, also called lamellae.
A centrosome is a cellular structure involved in the process of cell division. Before cell division, the centrosome duplicates and then, as division begins, the two centrosomes move to opposite ends of the cell.
