Chloroplasts Flashcards
what needs to be present for photosynthesis to occur
Forphotosynthesisto occur,chlorophyllmust be present. All Plants containorganellescalledplastids.Plastidscan containchlorophyll, these Plastids are calledchloroplastsand it is here that the magic ofphotosynthesisoccurs.
what is the structure of a chloroplast
Chloroplastsare surrounded by adouble membrane.Theouter membraneissemipermeablewhile theinner membraneis studded withtransportproteinsto facilitate themovementof substances into and out of the organelle.
Within the organelle, we findstacksofdisc-shapedcompartments calledthylakoids. These are formed bymembranescalledlamellaand arestackedto formgrana(singular:granum). It is within thethylakoidsthat we find chlorophyll pigments calledquantasomes. Stroma, which is theliquidpart ofchlorophyll,surrounds the thylakoids.
