Concept explainers
To describe:
The parts of the plant and the flower.
Introduction:
The plants are the living things, which are able to produce the food by using sunlight, water and carbon dioxide. They synthesize their food in the process known as photosynthesis.

Explanation of Solution
The plant can be broadly divided into two main body, the root system and the shoot system. The root system is the part of the plant present inside the ground and the shoot system is the part of the plant present above the ground. The root has one main body, which is known as the tap root. This body gives rise to the branch roots, which are smaller and widespread in the soil.
The shoot system mainly consists of stem, branches and the leaves. The stem is a long solid pipe like structure that give rise to the branches. The point where a branch emerges from the stem is called node. The space between two nodes is known as the internode. The branches further divided into the flat green surface known as leaf or leaf blade. The flowering plants have a bright color structure called flowers. The flower is the site of sexual reproduction in plants. The fruit is the food storage site of the plants, which are mostly consumed by the heterotrophs.
The stem is a solid structure made of three substances. The outer lining of the stem is known as the epidermal layer. The stem has a bundle of vascular tissues, that is xylem and the phloem and the remaining space is occupied by the ground substance.
A labeled diagram of the plant is given below:
The flower is the site of sexual reproduction in the plants. A typical flower has both male and female reproductive part, but some species may have a single sexual part. The structure of a flower consists of sepal, petal, carpel and stigma. The carpel is the female reproductive part and consists of stigma, style and ovary. The stigma receives the male pollen and style is the tube through which the pollen pass to the ovary. The ovary contains female gametes and ovule. The ovule forms the seed or the embryo. The male part is stamen, which consists of anther and filament. The anther contains the male gamete that is the pollen grain.
A labeled diagram of a flower is given below:
The plant body consists of root and shoot system and the flower consists of sepals, petals, carpel and stamen.

- Case Study—Ella Ella has a family history of diabetes. She wants to follow a healthful eating pattern that can lower her risk for developing this condition. Her dietitian recommends a goal of 450 to 600 kcal per meal and advises Ella to follow the Acceptable Macronutrient Distribution Range (AMDR) for carbohydrates and the Dietary Guidelines for Americans 2015-2020, which recommend limiting added sugar. She also recommends that Ella choose whole grains rather than processed grains. Ella decides to pack a lunch to take to work every day. This morning she’s making a sandwich for her lunch.
