Test: Transportation in Animals & Plants - UPSC

Transport of water and minerals  is through two kinds of elements of xylem tissue called xylem vessels and tracheid that water and minerals move from roots of a plant to its leaves.

During transpiration, the excess of water absorbed by the roots of plants get evaporated through stomata.

Red blood cells (RBCs) are responsible for transport of oxygen to different parts of the body due to presence of haemoglobin in it.

The ureter is a tubular structure which starts from the kidney and ends in the the urinary bladder .It's work is to carry urine formed in the kidney to the bladder for another temporary storage

Human heart is divided into four chambers. Heart receives oxygenated blood into upper chamber called left atrium.

The xylem and the phloem make up the vascular tissue of a plant and transports water, sugars, and other important substances around a plant. One xylem and one phloem are known as a 'vascular bundle' and most plants have multiple vascular bundles running the length of their leaves, stems, and roots.

Human beings sweats to maintain body temperature. Evaporation of sweat on the body surface leads to cooling effect.

Heart rate increases during exercise and fever because our body doesn't get enough of oxygen that is required for proper functioning of the body.

Red blood cells (RBCs) are also called as erythrocytes.

Functional unit of kidney is nephron. Each kidney contains thousands of neuron that filter the blood to remove wastes.

The nephron is the microscopic structural and functional unit of the kidney. It is composed of a renal corpuscle and a renal tubule. At the end of the tubule, the remaining fluid—urine—exits: it is composed of water, metabolic waste, and toxins.
