Which statement best describes what a thylakoid does during photosynthesis?
surrounds the grana and keeps them moist
enables the light-dependent reactions to occur
combines carbon dioxide and water to make sugar
the light-independent reactions to occur

The correct answer is enables the light-dependent reaction to occur.

Thylakoid enables the light-dependent reaction to occur during photosynthesis.

Thylakoid is termed as a membrane-bonded compartment which is found inside of cyanobacteria and chloroplast. They are much known for light-dependent reaction.

Thylakoid contains thylakoid membrane which is being surrounded by thylakoid lumen. Grana are stacks of disks which are formed from chloroplast thylakoids and connected by stroma thylakoids.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
