Tracheophyta

Transparent tracheophytes differ from bryophytes in that they have highly developed vascular systems that allow for the efficient transfer of water and nutrients throughout the plant’s whole body. Tracteophytes have become more entirely terrestrial as a result of their adaptation to vascularization, as opposed to bryophytes, which are still reliant on moist conditions for many […]

Tracheids and Vessels

Tracheids and vessels are the two water-conducting elements found in the xylem.  Tracheids are the major conductors in ferns and gymnosperms. Plants with vessels are known as angiosperms.  The tracheids are narrower than the vessels. Perforation plates can also be found near the ends of vessels’ cells.  As a result, the efficiency of water conduction

The Role of Transpiration Pull-in Plants

The Importance of Experimentation Plants relies heavily on the mechanism of transpiration. It generates a negative pressure gradient, which aids in the movement of water and minerals up through the plant out of its roots. Helps to keep the plant cool during hot weather — an evaporative cooling approach. Transpiration is the process through which

The Pressure-Flow or Mass Flow Hypothesis

Introduction The pressure-flow hypothesis often referred to as the mass flow hypothesis, is the best-supported explanation for sap transportation through the phloem. It was proposed by Ernst Münch, a German plant physiologist, in 1930. A diffusion gradient (osmotic gradient) is created when a high concentration of organic compounds, particularly sugar, inside phloem cells at a

The petiole

A leaf (plural leaves) is the major lateral appendage of a vascular plant stem that is normally carried above ground and adapted for photosynthesis. The leaves, stems, blossom, and fruit make up the shoot system. “Autumn foliage,” for example, is the collective name for leaves. Leaves are available in a wide range of forms, sizes,

Taproot

A ‘taproot’ is a plant’s main root, with vertical, thick, and long roots. Each root type has a unique set of functional roles and characteristics. In this article, we attempt to provide all relevant information about the taproot system. We see plants all around us but don’t know much about their roots. After reading this

Symplastic Pathway

It was Eduard Tangl who discovered the plasmodesmata in 1879, and it was Eduard Strasburger who developed the name “plasmodesmata” in 1901 to describe the symplastic transport. Hanstein was the first to use the term symplast, which was first used in 1880.Munch coined the terms apoplast and symplast, which are diametrically opposed to one another.

Symplast

Introduction Symplast is the protoplasts in plants interconnected by the plasmodesmata. The term “plasmodesmata” was introduced by Eduard Tangl, a professor of Botany and Pharmacognosy, when he discovered the cytoplasmic vascular strands connecting the plant cells. Plasmodesmata play a crucial role in the free movement of water and other low-molecular-weight solutes such as sugars, amino

Surface area of leaves

Leaves are a vital and critical component of plants. They operate as the plants’ food factory. Leaf surface area is directly related to the amount of photosynthetic light harvested, which has an effect on plant growth and yield. The plant is mostly reliant on its leaves to absorb CO2 and water, which are required for

Stomatal Transpiration

The term “transpiration” refers to the process of removing surplus water from the plant’s body. The most prevalent reason is water evaporation from the surface of the leaves. During transpiration, water molecules in plant tissues are removed from the aerial portions of the plants. Only a small amount of the water absorbed by plants is
