gather and process information from secondary sources, including electron micrographs to:
- draw and label the structure of a chloroplast
- compare the size, shape and distribution of chloroplasts in a named alga, terrestrial angiosperm and aquatic angiosperm
- Gather information from a range of resources such as the Internet or journals with diagrams, electron micrographs or other representations of chloroplasts. Use the Internet to find an electron micrograph and search for other information for the chloroplasts of an alga, a flowering plant on land and in water. Draw and label a chloroplast showing
- the thylakoid membrane and lumen or space
- the grana
- the stroma
- the inner and outer chloroplast membrane
- lamellae joining different grana throughout the stroma
- the thylakoid membrane where the photosynthetic units are found. (Photosynthetic unit = antenna complex + reaction centre)
- Process the information by assessing the relative importance of the information gathered. To do this draw a table as a comparison between the size, shape and distribution of chloroplasts in named examples of alga, terrestrial angiosperm and aquatic angiosperm. One is modelled below.
As a starting point try the sites below.
Chloroplasts and Photosynthesis
National Center for Biotechnology Information. Scroll down and enlarge photographs of chloroplasts.
Chloroplasts
University of NSW. Scroll down until you see the diagram of a chloroplast. There are links to electron micrographs.
