The central vacuole of some plant cells can occupy 50-90% of the cell volume.

Chloroplasts are involved in trapping light energy for photosynthesis. Leucoplast are colourless plastids that stores, material such as starch, oil and protein granules. Chromplasts are the coloured plastids that imparts colours to the plant.

Chloroplasts are pigment containing plastids. They are important for photosynthesis in plants. They contain various yellow or orange pigments in addition to chlorophyll.

When the light passes through the solution, then scattering of light by colloidal particles is observed and path of light beam becomes visible. This phenomenon is known as Tyndall effect

Starch solution is a colloidal solution; hence, it will show Tyndall effect.
