Diffusion
Nutrients enter cells through a process called active transport or passive diffusion. Active transport requires energy and specific carrier proteins to move nutrients across the cell membrane, while passive diffusion relies on the concentration gradient to allow nutrients to move freely into the cell. Once inside the cell, nutrients are transported to different parts of the cell through various pathways, such as vesicle transport or protein channels.
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.
After nutrients are digested in the small intestine, they are absorbed into the bloodstream through the walls of the small intestine. This process is facilitated by tiny blood vessels called capillaries and specialized cells that line the intestine, allowing the nutrients to be transported to different parts of the body for energy and growth.

Water enters a plant primarily through the roots via a process called osmosis. The roots absorb water from the soil along with essential nutrients, which is then transported through the plant's vascular system to the leaves for photosynthesis and other metabolic processes.
Absorption is the process that takes nutrients through the small intestine wall. These nutrients then enter the circulatory system, which carries the nutrients to all body cells.

Water enters the atmosphere from the surface of plants through a process called transpiration. Transpiration is the movement of water through a plant and its evaporation from the aerial parts, such as leaves and stems, into the atmosphere. This process helps plants regulate temperature, maintain cell turgidity, and transport nutrients.

The transport of nutrients from the gastrointestinal tract into the body is called absorption. This process occurs primarily in the small intestine, where digested nutrients pass through the intestinal walls and enter the bloodstream or lymphatic system for distribution to cells and tissues. Efficient absorption is crucial for providing the body with essential vitamins, minerals, carbohydrates, proteins, and fats necessary for overall health.
through protein passageways
Substances enter the roots of plants through a process called root uptake. Root uptake involves the movement of water and solutes by various mechanisms such as diffusion, osmosis, and actively transporting ions into root cells. This process allows plants to absorb essential nutrients and water from the soil solution.

Pinocytosis, often referred to as "cell drinking," is a process by which cells take in small droplets of extracellular fluid along with dissolved solutes. This mechanism allows the cell to absorb nutrients, ions, and other small molecules present in the fluid. Substances such as glucose, amino acids, and various nutrients can enter the cell through this process.
