A channel in the cell's plasma membrane.
it controls the movement in and out of the cell . examples : water, food, oxygen and wastes
Cytoplasm carries food and water to the cells.

The movement of large particles of solid food or whole cells into the cell is called phagocytosis. Phagocytosis occurs in three separate steps.
The valve that controls the movement of food between the stomach and small intestine is called the pyloric sphincter. It regulates the passage of partially digested food from the stomach into the small intestine for further digestion and absorption.
In sponges, food is transported primarily through the movement of water facilitated by specialized cells called choanocytes. These cells have flagella that create water currents, drawing in water and trapping tiny food particles like bacteria and plankton. The trapped food is then engulfed by the choanocytes through phagocytosis and can be passed on to other cells, such as archaeocytes, for digestion and distribution throughout the sponge's body. This simple yet effective system allows sponges to efficiently filter and process food from their aquatic environment.

COLUMNAR EPITHELIAL CELLS ARE FOUND IN THE ESOPHAGUS. THEY HELP IN THE PERISTALSIS MOVEMENT OF THE OESOPHAGUS TO MOVE THE FOOD THROUGH IT TO THE STOMACH.

Cells affect growth by supporting the system with food and water. The more food and water a cell takes in the more they grow.
In plant cells, food and water are stored in the central vacuole. Animal cells do not have a central vacuole, so food and water are stored in organelles like mitochondria and the cytoplasm.
i think there are relation between your food and your bloodtype. i think it controls your red blood cells and how your blood reacts to each food you are eating and how sweet.
