Fig. 1.1 shows a transmission electron micrograph of part of a chloroplast. [Figure 1.1]

1. (a)Table 1.1 describes some functions that occur in different parts of a chloroplast. Complete Table 1.1 by identifying the letter on Fig. 1.1 that is a location matching the description. Each letter may be used once, more than once, or not at all. [Table 1.1][4]
2. (b)(i)Membranes of the type labelled C in Fig. 1.1 were made into a liquid extract. Chromatography was then used to separate and identify the coloured components (pigments) in this extract. The resulting chromatogram showed that these membranes contain a yellow pigment, an orange pigment, a green-brown pigment and two different green pigments. Describe how you would carry out chromatography to separate and identify the coloured pigments in the liquid extract of C.[4]
3. (b)(ii)Explain why membrane C has many different coloured pigments to function efficiently.[3]
