TRANSPORT OF WATER AND MINERAL SALTS INTO THE LEAVES OF A FLOWERING PLANT
Water and mineral salts are transported into the leaves of a flowering plant through a process called transpiration. Transpiration is the loss of water vapor from the plant’s aerial parts, primarily through the stomata on the leaves. This process relies…
CELL COMPARTMENTALISATION AND PROTEIN TRANSPORT IN CELLS
Cell compartmentalisation refers to the organization of eukaryotic cells into distinct membrane-bound compartments called organelles. These organelles serve specific functions within the cell and are essential for maintaining cellular homeostasis. Proteins are transported between organelles through a complex network of…
EXPLORING SUBSTANCE TRANSPORT THROUGH CELL MEMBRANES
Diffusion through the Cell Membrane Diffusion is the process by which particles move from an area of higher concentration to an area of lower concentration until they are evenly distributed throughout a space. This process occurs in solids, liquids, and…
ACTIVE TRANSPORT OF SUBSTANCES THROUGH MEMBRANES
Introduction Active transport is a vital process that allows substances to move across cell membranes against their concentration gradient, requiring the expenditure of energy. This mechanism is crucial for maintaining homeostasis and ensuring the proper functioning of cells and organisms.…
UNDERSTANDING THE SCIENCE OF OXYGEN TRANSPORT
Introduction Oxygen transport refers to the process by which oxygen is transported from the lungs, where it is absorbed into the bloodstream, to the body’s tissues, where it is used for cellular respiration. This process involves several steps and components,…
TRANSPORT SYSTEM
The transport system carries food and oxygen to all tissues and removes waste materials of metabolism, convenes hormones from ductless glands to their target organs and the body temperatures are equalized. Needs for transportation In Amoeba and many simple…
WATER TRANSPORT
Water transport is the means of conveying goods and people from one place to another through the rivers, seas or oceans by ships, canoes etc. This facilitates international trade between different nations because goods and passengers can be easily transferred.…
TRANSPORT BY AIR
Transport by air is the system of moving goods and passengers through the air by aeroplanes, helicopters etc. Air transport is very fast and comfortable but it is expensive. Air transport has contributed greatly to commercial activities in international trade.…
TRANSPORT BY PIPELINE
Transport by pipeline is a system of transporting gasses and liquid products from one place to another through the use of pipelines. Pipelines are constructed or laid underground as means of carrying water, gases and petroleum products. In Nigeria, pipelines…
TRANSPORT BY LAND
Transport by land is the means of conveying goods and passengers from one place to another through land. This means of transportation is very good for trading within a country, i.e ., home trade. Land transport can be divided into…
