Plant growth regulators: Auxins, gibberellins, cytokinins

Growth is the most fundamental characteristic of any living being. Like animals, plants also grow and change their size over time. Plant growth and development depend on multiple intrinsic (internal) and extrinsic (external) factors. External factors include humidity, temperature, light, and nutrients and internal factors include plant growth regulators. Types of Plant Growth There are […]

Seed dormancy may appear to be nothing more than a stumbling bar to the complete germination of an intact healthy seed under ideal conditions, but previous evaluations determined that it is one of the most poorly understood processes in seed biology. There has been a great number of published material and substantial progress in understanding

Sclerenchyma (from the Greek scleros, meaning “hard”) is made up of long, thin, and thick cells. Due to the deposition of lignin, these cells have extremely thick walls. Sclerenchyma cells that have reached maturity are unable to extend, and they are found in sections of the plant that have ceased to expand in length. At

Seed dormancy affects some wildflower species more than others, and many of them require unique techniques to break dormancy and stimulate germination. Moisture must be allowed to penetrate seeds in order for them to germinate. Scratching and shattering seed coatings, immersing seeds momentarily in hot water or severe acid, or exposing seeds to fire are

Introduction Bryophyta is derived from the Greek words ‘Bryon’ which means moss and ‘Phuton’ which means plants. Embryophytes such as mosses, hornworts, and liverworts belong to the Bryophyta family. These are tiny plants that thrive in shaded and moist environments. They are devoid of vascular tissues. Instead of flowers and seeds, they reproduce through spores.

Parts Of Plants Plants are among the most important living things on the planet. Both animals and humans benefit enormously from them. They generate oxygen, which is necessary for living beings to survive. Animals seek refuge in trees, which are also recognized for their therapeutic properties. Plant components play a variety of roles. They provide

Introduction Vegetative parts like root, stem and leaves along with other parts like flowers and their tiny buds are vital parts of plants, although these structures are very varied, tailored to different plant species’ demands and environments. These organs are equally crucial to the plants as much as plants are necessary for the survival of

The roots are modified organs found in vascular plants that transport water and nutrients to the plant body, allowing the plants to grow taller more quickly. The majority of the time, they are found below the soil surface, although some of the roots may be aerial and grow above it. What are Plant Roots? The

Hundreds of billions of years of evolution have resulted in the plants we see today. Plants now cover over 30% of the whole area and contribute to 50% of plant productivity (generation of biomass). Plants play a wide range of roles in the ecosystem. They provide food, nutrition, shelter, and soil integrity (by preventing erosion),

Root growth  Roots show both main and secondary development (in terms of length and depth) (in width or diameter). Plant development is controlled by actively dividing cells, called meristems, as you probably guessed. Secondary meristems, the dividing tissue visible in cross-sections, generate thicker roots, whereas primary (apical) meristems, the dividing tissue at the tips of
