What are Platelets? Platelets are small, colourless blood cells that play an important role in the human body. They are formed in the bone marrow and circulate in the blood. …
What will happen if Platelets were Absent in the Blood Read MoreA neatly labeled xylem diagram to understand xylem tissue. Xylem consists of vessel elements, tracheids, fibers and parenchyma cells each with unique functions in water and nutrient transport and structural support. Important features such as cytoplasm, the nucleus and bordered and simple pits are also shown in the diagram. Students can use this easy-to-draw diagram for their assignments and exams.
Xylem Diagram Read MoreXylem is a vital plant tissue responsible for the transport of water and nutrients from the roots to the leaves. It is made up of several components, including tracheids, vessel elements, fibers and parenchyma cells. Tracheids and vessel elements form long tubes that allow for efficient water transport, while fibers provide structural support. Parenchyma cells help with storage and metabolic functions.

Xylem and phloem are vital plant tissues with different tasks. Xylem transports water and nutrients upwards from the roots, while the phloem transports sugars from the leaves to other parts of the plant. Their composition, flow direction, location, transport mechanism, speed of movement, response to injury, fibres, distribution, movements and roles within plants provide fascinating insights.
15 Difference between Xylem and Phloem Read MorePhloem tissue is a type of vascular tissue in plants that transports sugars, amino acids, hormones and other organic compounds from the leaves to the rest of the plant. The tissue is made up of several different types of cells like sieve tube elements, companion cells, phloem parenchyma and phloem fibers. Phloem tissue plays a critical role in plant growth and development by facilitating the transport of hormones, defending against pathogens, transmitting signals and storing nutrients. There are two types of phloem tissue- primary phloem and secondary phloem.
Phloem – Definition, Structure, Function, Types and How does Phloem tissue work Read MoreThe Phloem is a plant tissue responsible for translocating organic nutrients and other substances from leaves to other parts of the plant. Longitudinal and Transverse Phloem Diagrams show the internal structure of the tissue, including Sieve tubes, Companion Cells, Phloem Fibers and Phloem Parenchyma cells.Netaly labelled easy to draw Phloem Diagram – Longitudinal and Transverse Section Diagram of Phloem Tissue explained with description of Labels

Xylem is a specialized tissue in vascular plants that transports water and minerals from roots to the rest of the plant. It is composed of tracheids, vessel elements, xylem parenchyma, xylem fibers and xylem rays. Water transport is driven by root pressure and transpiration pull. Xylem provides structural support, stores nutrients and transports signaling molecules. Its transport mechanism is a combination of physical and biological factors.

Blood pressure is a vital sign that reflects the pressure of blood against the walls of arteries. Systolic blood pressure is the pressure in the arteries when the heart contracts and pumps blood out into the body, while diastolic blood pressure is the pressure in the arteries when the heart is at rest between beats. This article will provide an in-depth look at the differences between systolic and diastolic blood pressure, and why they are important .

The human Heart has four chambers, and four valves ensure that blood flows in the correct direction. The valves are made up of thin flaps of tissue that open and close like doors. There are four main types of Heart valves – the Aortic Valve, Mitral Valve, Pulmonary Valve and Tricuspid Valve. Each valve plays a vital role in regulating blood flow in and out of the Heart. Any problems with the valves can lead to a variety of conditions that affect Heart function.
