The main function of vascular cambium cells is the production of new tissues and cells that are required during the growth and development of flowers. These cells actively divide through mitosis, generating new stem cells that differentiate into different cell types.

Flowers have two primary parts: the vegetative part, which includes the petals and the sepals, and the reproductive part, encompassing the stamen (male reproductive organ) and the pistil or carpal (female reproductive organ).
The primary function of a flower is reproduction, ensuring the survival of the species. Through the process of pollination and fertilization, flowers produce seeds. Each seed contains a new plant, waiting for the right conditions to grow.
Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma. This process can occur through self-pollination or cross-pollination: 1. Self-pollination: This occurs when the pollen from an anther deposits onto the stigma of the same flower or another flower on the same plant. Self-pollination is common ...

ISBN 978-1-284-07753-7.Jun 26, 2021 · The process of flower development involves the formation of very complex structures. Flowers generally arise from the inflorescence meristem, where cellular differentiation processes give rise to specialized structures involved in all the aspects of plant reproduction.

- Sepals: The sepals form the outermost whorl of a flower and are usually green in color. Collectively known as the calyx, sepals act as protective covers for the developing flower bud before it blossoms.
- Petals: The colorful and often fragrant petals lie just above the sepals and form the corolla of the flower. Their vibrant hues and enticing scents attract pollinators such as bees, butterflies, and birds.
- Stamens: Stamens are the male reproductive organs of a flower and comprise the androecium. Each stamen typically consists of two parts: Anther: The anther is a yellowish sac-like structure located at the top of the stamen.
- Pistil: The pistil is the female reproductive organ of the flower and forms the gynoecium. It is usually located at the center of the flower and comprises three parts
