Answer 1

Explanation:

Tomatoes are triggered to turn red by a chemical called ethylene. Ethylene is odorless, tasteless and invisible to the naked eye. When the tomato reaches the proper green mature stage, it starts to produce ethylene.

Answer 2

Answer:

Correct option is

A

Chloroplasts are changed into chromoplasts

Chromoplast are coloured plastids containing pigments other than chlorophylls. Chromoplasts contain fat soluble carotenoid pigments and are yellow, orange or red in colour. They are formed either from leucoplast or chloroplasts. Change of colour from green to red during ripening of many fruits (tomatoes, chillies) is due to transformation of chloroplast to chromoplasts. Orange colour of carrot is due to the presence of chromoplasts. The latter also provides colour to many flowers and fruits.
