Introduction Seed dormancy is the intrinsic property of a seed that determines the environmental conditions for the seeds to germinate. Seed dormancy can be defined as a condition in which seeds are prevented from germinating under favourable conditions such as temperature, light, water, gases, seed, coats, etc. Seeds require an ample amount of time before […]

Introduction In terms of the higher plant’s survival as a species, the seed is a crucial step in its life cycle. It is the plant’s dispersion unit that may survive the time between seed maturation and seedling establishment as a seedling once it has germinated. The seed is well adapted to survive extended periods of

The seed coat is the hard or semi-hard coating that protects the seed from numerous insects and illnesses, according to botany. Seed coverings also keep extra water from reaching the seed, preventing it from germinating prematurely. Harder shells help protect the seed from mechanical stress and humidity variations. The seed coat also serves as a

Introduction The seed is the part of a plant that grows from the ovules after fertilisation. They’re contained within the fruit that grows from the fertilised ovary.  Sexual reproduction produces seeds, which contain a young embryo capable of growing into a new plant. Although the anatomy of seeds of different plants may differ in many

Meristematic tissues are generally known as meristems. The term ‘meristem’ was coined by Carl Wilhelm von Nägeli. They are undifferentiated plant tissues composed of immature cells that are not fully differentiated. Cells of the meristematic tissues can divide and remain young forever. Meristematic tissue acts as the building block of plants. It contains living cells

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.
