Absorption
Absorption in biology refers to the process by which substances, such as nutrients and water, are taken up by cells and tissues in the body. This process typically occurs in the digestive system, where nutrients from food are absorbed into the bloodstream for use by the body's cells.
Cells whose main function is absorption would typically have a large surface area, such as microvilli or brush border, to increase their ability to absorb nutrients or substances. Additionally, these cells may have specific transport proteins and channels to facilitate the movement of molecules into the cell. They may also contain high concentrations of mitochondria to provide energy for the absorption process.
The process of absorption of water by cells is called osmosis. Osmosis is the movement of water across a selectively permeable membrane, such as the cell membrane, from an area of higher concentration to an area of lower concentration.
Photosynthesis takes place within the mesophyll cells of the leaf. This process involves the absorption of sunlight, carbon dioxide, and water to produce glucose and oxygen. Chloroplasts within the mesophyll cells contain chlorophyll, the pigment responsible for capturing sunlight and initiating the photosynthetic reactions.

Absorption
The end products of digestion enter the cells of a vertebrate through a process called absorption. This occurs mainly in the small intestine, where nutrients like glucose, amino acids, and fatty acids are absorbed through the intestinal lining into the bloodstream to be transported to cells throughout the body.

Process of dissolving and chemically converting food for absorption by cells in the body.

The process that permits absorption of glucose into cells is called facilitated diffusion. Glucose is transported across cell membranes with the help of glucose transport proteins, such as GLUT-1 and GLUT-4. These proteins allow glucose to move down its concentration gradient and into the cells where it can be used for energy production.
Adsorption is the process by which a gas dissolves into the surface of a solid, which will normally be metal. There are actually two types of absorption. Adsorption and Absorption ABsorption actually happens in the digestive process.
Yes, the absorption of oxygen into individual cells is part of respiration. Once oxygen is absorbed by cells, it is used in cellular respiration to generate energy in the form of ATP through a series of biochemical reactions. This process is essential for the survival and function of cells in the body.
Cells found in the roots of the plant assist in the uptake and absorption of water and nutrients from the soil. There are a number of different types of cells (tissues) involved in this process and not just a single cell type.
Absorption in nutrient uptake occurs in the small intestine, where nutrients are broken down into smaller molecules for absorption into the bloodstream. Villi and microvilli in the small intestine increase surface area for absorption. Nutrients are then transported to cells throughout the body for energy and growth.
