Explanation:
Plasmodesmata are the plasma membrane lined pores present in the cells of the plants. Inside these pores runs a closed tubelike structure which is an extension of the endoplasmic reticulum.
The plasmodesmata allows cell to cell communication which involves symplast mode of transport that is through its cytoplasm.
The small water soluble molecules like amino acid and sugars can easily pass through these plasmodesmata via diffusion. The large molecules can be transported through these plamodesmata through selective diffusion.
Thus, Option-D is the correct answer.
Flowers of plants that are pollinated by animals such as birds or insects are usually colorful. Colours sometimes helped by coloured guiding marks attract animals. Also, flowers are often shaped to provide a landing platform for animals, especially insects or have scent to attract them. Flowers adapted to birds’ pollination are often long-shaped with lots of nectar.
When it comes to wind-pollinated (or water) plants, it is important for them to produce a huge amounts of pollen, to have small petals or no petals at all (like grass). Also, the stigmas of receiving flowers have to be sticky.
