Question
Chapter 45.3, Problem 1HYEW
Summary Introduction
To determine:
When can a fruit be called a vegetable.
Introduction:
Fruits are basically the plant structures that possess seeds and are formed from an ovary. Generally, fruits mean fleshy structures containing seeds. These can be eaten in their raw state. The outer layer of the fruits is known as the pericarp. Pericarp contains three layers; epicarp, mesocarp, and endocarp.

Most of the approximately 900 species of gymnosperms are conebearing plants. On the surfaces of their cone scales are ovules, which later become seeds. These ovules are said to be naked because they are not completely enclosed by diploid tissue (as the ovules of angiosperms are). This characteristic gives the gymnosperms their name; gymnos is a Greek word meaning naked, and sperma means seed. Botanists now divide the gymnosperms into four groups: conifers, cycads, ginkgos, and gnetophytes.

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.

The plant material you obtain only consists of mature seeds - this can be challenging as mature seeds are often quite hard making it difficult to cut a longitudinal slice through the seeds from each genus. In addition to your drawings, you described (with great accuracy) what you saw as follows: A. The coyledons of the Ricinus embryo were just about visible, though often hard to distinguish, surrounded by the nutritive endosperm tissue. The seeds of Taxus were too mature to slice open but they were surrounded by the fleshy, red tissue that contains the poisonous substance taxol. B. The coyledons of the Ricinus embryo were just about visible, though often hard to distinguish, surrounded by the nutritive endosperm tissue. The seeds of Taxus were too mature to slice open but they were surrounded by the fleshy, red tissue that birds eat. C. The coyledons of the Ricinus embryo were just about…arrow_forward
