Question

Identify the difference between leucoplast and chromoplasts.
A) Leucoplasts-colourless plastids, chromoplasts-coloured plastids
B) Leucoplasts-coloured plastids, chromoplasts-colourless plastids
C) Leucoplasts-help in storage of food, chromoplasts-help in photosynthesis, pollination
D) Both A and C

Answer 1

Hint: The plants have different colours of fruits, flowers, and sometimes leaves, the colour is due to the presence of pigments that involve different functions of plants and pollination process.

Complete Answer:
To solve this question, we have to know about plastids.
- The plant cell has the same organelles as that in an animal cell but the plant consists of some additional organelles one of those is plastids.
- The plastids are double membrane organelles that involve in the photosynthetic process of the plants; the phenomenon of preparing and storing food.

Plastids have three different types; Chromoplast, chloroplast, and leucoplasts.
1) The Chromoplast is the colour plastid that is found in every flower and fruit, it is responsible for the different colour of flower and fruits. This is also helpful in the pollination process as due to the colour the nectar sucking birds attract towards the flower and carry out pollination.
2) The chloroplast is the green pigment found in the plants because of which we observe plants are green in colour that is considered as chlorophyll.
3) Leucoplasts are the colourless pigments found in the plants that involve the storage of protein, starch, and lipid inside the plant cell. Therefore, the difference between the Chromoplast and leucoplast is that Chromoplast has coloured plastids while leucoplasts are colourless plastids.

Hence the correct answer is ‘A’. Leucoplasts-colourless plastids, chromoplasts-coloured plastids.

Note: Chloroplast is the green pigment and it is involved in the photosynthetic process. It consists of a guard cell found in the leaves that traps the sunlight and absorbs the water involved in the process of making food. Students may get confused between the function of chloroplast and Chromoplast.
