Question

The type of tissue present in the petioles of banana and canna is
A. Stellate parenchyma
B. Prosenchyma
C. Aerenchyma
D. Chlorenchyma

Answer 1

Hint:
> Stellate parenchyma cells are available in the petioles and midribs of Canna and banana leaves.
> These are aerenchymatous tissues that are composed of parenchyma cells and are found in aquatic plants.
> These cells help in air circulation in the aquatic plants because of the presence of enormous intercellular spaces.

Complete answer:
Bananas are among the biggest herbs on the planet and their lightweight petioles hold up tremendous leaves. The empty U-molded segment of the petiole and the longitudinal fortifying components in its external skin give it satisfactory unbending nature, while its ventral shape helps uphold the leaf without the requirement for thick horizontal veins. These highlights, be that as it may, likewise permit the petiole to reconfigure by turning endlessly from the breeze, while the leaf can overlay away. Furthermore, two arrangements of inner structures, longitudinal partitions and cross over stellate parenchyma plates, help forestall dorsoventral leveling, permitting the petiole to flex further away from the breeze without clasping.

Canna is a monocotyledon and an individual from the Cannaceae. In any event seven species and numerous cross breeds have been created on the grounds that the plant has huge showy blossoms. The petioles and leaves of Canna display a few hydrophytic qualities, including prominent airspaces that navigate the petiole and leaf cutting edge structure. Their slim walled parenchyma cells are without chloroplasts, and are accordingly colourless. It has aerenchymatous tissue.

The kind of tissue present in the petioles of banana and Canna, is C) aerenchyma.

Note:
> It is a kind of Permanent tissue.
> These are found in Aquatic plants and in additionally some land plants.
> These have enormous air depressions which are encased by the parenchyma cells.
> These cavities encourage the arrangement to be light as they store gases.
> They likewise make it light and buoyant.
