Chloroplasts and Photosynthesis
For a labelled diagram of a chloroplast together with study notes see the main page about chloroplast structure.
The very simple information in the 3 video clips on this page has been added just for fun . Students using these pages to help with homework or revise for exams might enjoy the following light relief - at least play the 3rd video "The Photosynthesis Song".
The first video-clip is a quick (1 min, 20 sec) reminder of the main parts of a chloroplast - including the outer membrane, inner membrane, stroma, thylakoids and grana:
The following is cute but very simple - probably too simple for exam courses, but it only takes a minute ...
Ok, so that explains that chloroplasts are important for photosynthesis, but what is photosynthesis ?
Here to explain, to remind you, or just to make you smile is ...
The Photosynthesis Song
Remember : Chloroplasts are the organelles that are the sites of photosynthesis in eukaryotic cells.
A chloroplast is an organelle (found inside plant cells but not animal cells); a chloroplast is not a cell.
For more about cells: the structure of a plant cell, the structure of an animal cell & comparison of plant, animal and bacterial cells.
