Thylakoids float in the liquid filling the chloroplast, called the stroma. The part of the Thylakoids between two Grana is called a Lamella. Most importantly, they are the sites of the light-dependent reactions, which occur in the first step of photosynthesis.
All of these answers are correct. [large chloroplasts with numerous starch grains, high concentrations of PEP carboxylase in mesophyll cells, higher optimum temperatures for photosynthesis than C3 plants, small chloroplasts with well-developed grana]
