Which one of the following type of plastids helps in pollination and seed dispersal?
- A
Amyloplast
- B
Chloroplast
- C
Chromoplast
- D
Leucoplast
Chromoplasts give color to the plant and thus is responsible for its pollination.
Amyloplasts are specialized plastids in plant cells that store starch, a carbohydrate reserve. They are not involved in processes like protein degradation, lipid metabolism, or lysosomal functions. Therefore, their role is limited to carbohydrate storage and they are not relevant in contexts unrelated to starch accumulation.
Chloroplasts are plant cell organelles that capture light energy and convert it into chemical energy through photosynthesis. They contain chlorophyll and other pigments essential for this process. Chloroplasts are not involved in functions like carbohydrate storage or lysosomal activity, so their role is specific to energy production via photosynthesis.
This statement is correct. Chromoplasts are plastids that contain pigments like carotenoids, which give flowers, fruits, and other plant parts their distinctive colors. These bright colors help attract pollinators such as bees, birds, and insects. By aiding in pollination, chromoplasts indirectly support the plant’s reproductive process.
Leucoplasts are non-pigmented plastids in plant cells that store essential compounds, including starch, oils, and proteins. They do not contribute to photosynthesis or pigmentation. Their main role is nutrient storage and biosynthesis of certain molecules, rather than attracting pollinators or producing pigments.
