The correct option is
D Pollination and seed dispersal
The correct option is D
Explanation of the correct option :
- Pollination is a process where pollen grains are transferred from anther to stigma of a flower.
- It can occur within the same plant (self pollination) or between different plants (cross pollination).
- In cross pollination, pollinating agents like bees, butterflies etc. are required.
- The pollinating agents carry the pollen grains from one flower to another, thus facilitating pollination.
- When seeds are produced by a plant, animals ingest them.
- These seeds will be removed from their bodies through the faeces at a distance from the parent plant and develop into new plants, thus getting dispersed.
Explanation of the incorrect option:
Option A:
- Asexual propagation of plants occurs from the plant parts either naturally or artificially.
Option B:
- Translocation of organic nutrients occur within the plants by the phloem tissues.
Option C:
- Control of plant growth is taken care by plant hormones and external factors like sunlight, water availability etc.
Final answer: Animals help in pollination and seed dispersal.
