Question

Write a note on the detailed structure of the Chloroplast.

Answer 1

The chloroplast which is a widely occurring plastid of green plants may be filamentous, saucer-shaped, spheroid, ovoid, discoid or club – shaped. It is vesicular, having a colourless centre.

It’s size varies from 2 to 3µ in thick­ness and 5 to 10µ long (Hall et al., 1974). In higher plants there are usually 20 to 40 per cell.

However, in many algae there may be only one or a few chloroplasts, and these may be star-shaped or a spiral ribbon or may have other exotic forms.
