Absorption in plant bodies occurs primarily through root hairs, which increase the surface area for water and nutrient uptake. Water and minerals are absorbed by root hairs through osmosis and active transport, and then transported throughout the plant via vascular tissues like xylem and phloem. Nutrient absorption is facilitated by mycorrhizal fungi, which form symbiotic relationships with plant roots.
Plant root is specialized for anchorage and absorption.
The four stages of processing food in the human body are ingestion (taking in food), digestion (breaking down food into nutrients), absorption (absorbing nutrients into the bloodstream), and elimination (removing waste).
Simple cuboidal epithelia are found in areas of the body where secretion and absorption processes occur, such as in the kidney tubules, thyroid gland, and small ducts of various glands. They are characterized by a single layer of cube-shaped cells with a centrally located nucleus, which facilitates their specialized functions of secretion and absorption.
Mineral absorption in plants occurs mainly in the roots, specifically in the root hair cells. These cells have specialized structures called root hairs that increase surface area for absorption. Minerals are absorbed through the roots and transported to other parts of the plant through the xylem and phloem tissues.
Secretion and absorption processes primarily occur in the digestive system. Secretion of digestive enzymes and acid takes place in the stomach, pancreas, and small intestine, while absorption of nutrients occurs mainly in the small intestine through its lining known as villi.
Most water absorption in the human body occurs in the small intestine.
Water absorption primarily occurs in the small intestine of the human body.
Water absorption into the bloodstream primarily occurs in the small intestine of the digestive system.

Absorption of CO2 occurs via photosynthesis; release of H2O is respiration: both occur in plant cells - the former only in light conditions and the latter continuously.
