Chapter 40, Problem 3CQ
Summary Introduction
To describe: The reason behind the diversity in colors and shapes of the flowers.
Introduction: In plants, the process of sexual reproduction takes place by means of a sexual structure called flower. In flowers, the male and female reproductive structures are present which produce male and female gametes, respectively. Later, these gametes fertilize together and form zygote.

In both cases the plants live in desert environments. They have a succulent stem that stores water, no leaves (reduces water loss), stems that can perform photosynthesis, and spines that protect the plant from being eaten. The spines are formed from different parts of the plant in the two families. The two plant families are not closely related.

The work of plant taxonomists of the 20th century who identified /established the different families of flowering plants based mainly on morphological and anatomical details is still valued and being used today, despite the general acceptance of the Angiosperm Phylogeny Group (APG) as a classification system for the flowering plants.
