I am a Hibiscus plant. I have __________ type of root system. My leaves have __________ venation. My flowers are __________merous. Therefore, I belong to the __________ Division and __________ subdivision.

Answer 1

Hint: Hibiscus is a renowned flowering plant that belongs to the family Malvaceae. It is also known as the mallow family. The Hibiscus is the largest genus of Malvaceae. It consists of economically important and ornamental plants.

Complete answer: The Hibiscus is a flowering plant. It is known to bear large-sized and bright coloured flowers.
a) Roots: Hibiscus is a dicot plant. Dicot plants have a branched tap root system. The taproot system is the system of roots that originate from the radicle directly. This root arising from the radicle directly is known as the primary root. Several secondary branches originate from the primary root, forming a branched network system. The secondary system is further branched into the tertiary roots.
b) Leaves: The leaves of Hibiscus are stipulated, which means that the stipule is present. The stipule is a small leaf-like structure developed near the base of the leaf. It provides extra protection to the early leaf. It has a reticulate and unicostate venation. Reticulation involves net-like and unicostate involves having a single mid-rib. The leaves have an alternate phyllotaxy, where a single leaf arises from each node.
c) Flowers: Hibiscus has pentamerous flowers as five petals are present in the floral whorl or the corolla. The flowers are hypogynous where the ovary is superior. They have twisted aestivation, where petals are situated in a manner that one margin is inside and the other is outside.
d) Division and subdivision: They have the Tracheophyta division because they have well developed vascular bundles present for the conduction of food and water. Their subdivision is Spermatophyta because they constitute plants that bear seeds. Thus, based on the above information the blanks can be filled as;
I am a Hibiscus plant. I have branched taproot type of the root system. My leaves have reticulate venations. My flowers are Pentamerous. Therefore, I belong to the Tracheophyta Division and Spermatophyta subdivision.

Note: Hibiscus is also known as rose mallow, Hardy Hibiscus, tropical Hibiscus and rose of Sharon. This genus consists of perennial and annual herbaceous plants. Some species are woody shrubs and small trees. These plants are cultivated for ornamental purposes normally.
