Mnemonic Explanation: "Ticket Collection Advances - Said CM" mnemonic, you can easily recall some of the important functions of the plant hormone cytokinin. Cytokinins are crucial regulators of plant growth, development, and responses to various environmental cues, contributing to the overall health and vitality of plants.

Stages of Plant Growth

Mnemonics: Plant: Growth & Development | Biology Class 11 - NEET

  • Germination: Germination is the first stage of plant growth. It starts when a seed absorbs water and swells, leading to the emergence of the embryo from the seed coat. The embryo then undergoes rapid cell division and elongation, forming the primary root (radicle) and shoot (plumule). The radicle develops into the primary root, and the plumule grows into the primary shoot.
  • Seedling Stage: The seedling stage follows germination. At this stage, the plant continues to develop its primary root and shoot system. The roots grow and branch out to anchor the plant and absorb water and nutrients from the soil. The shoot system develops leaves, stems, and eventually, branches. The plant focuses on establishing a strong root system and building its energy reserves through photosynthesis.
  • Vegetative Growth: During the vegetative growth stage, the plant grows and produces new leaves, stems, and branches. The primary objective of this stage is to enhance the photosynthetic capacity of the plant and build up its biomass. Vegetative growth is essential for plant development and occurs before flowering and fruiting.
  • Reproductive Stage: The reproductive stage is marked by the formation of flowers and the production of seeds or fruits. In this stage, the plant allocates its resources towards reproductive structures and processes. Flowers contain the reproductive organs (stamens and pistils) that are essential for pollination and fertilization. After successful pollination and fertilization, the plant produces seeds or fruits that contain the developing embryos.
  • Senescence: Senescence is the final stage of plant growth, characterized by the aging and deterioration of plant tissues. As the plant reaches the end of its life cycle or growing season, various factors trigger the breakdown of chlorophyll and other components, leading to leaf yellowing and eventual death. During senescence, nutrients are reabsorbed from older tissues and transferred to newer parts of the plant, such as seeds or fruits, to support reproduction and seed development.
  • Seed Formation and Dispersal: After successful pollination and fertilization, the seeds mature within the fruits. Once the seeds are fully developed, the fruits may undergo changes to facilitate seed dispersal. Different mechanisms, such as wind, water, animals, or self-dispersal, help seeds to move away from the parent plant and establish new individuals elsewhere, thus completing the plant life cycle.
