Xylem and phloem are vascular tissues that perform vital functions in plants. Xylem transports water and minerals from the roots to the rest of the plant, providing hydration and structural support. Phloem transports organic nutrients, such as sugars and amino acids, produced during photosynthesis to different parts of the plant, supporting growth, metabolism, and energy production. Together, xylem and phloem facilitate nutrient and water distribution, essential for plant growth and survival.
Simple permanent tissues consist of a single type of cell with similar structure and function, such as parenchyma, collenchyma, and sclerenchyma.

Simple permanent tissues consist of a single type of cell with similar structure and function, such as parenchyma, collenchyma, and sclerenchyma. They perform basic functions like storage, support, and photosynthesis. Complex tissues, however, comprise multiple types of cells working together, such as xylem and phloem. These tissues conduct specialized functions like water transport, nutrient distribution, and mechanical support, making them structurally and functionally distinct from simple permanent tissues.

The primary function of cork cells in the outer protective tissue of a plant, known as the cork cambium or phellogen, is to provide a protective barrier against physical damage, pathogens, and water loss. Cork cells are impregnated with suberin, a hydrophobic substance that makes them impermeable to water and gases, enhancing their protective qualities. Additionally, cork cells contribute to the structural integrity and longevity of the plant’s stem and roots.

Oxygen is absorbed during breathing in the lungs, specifically in the alveoli, small air sacs where gas exchange occurs. Inhaled oxygen diffuses across the thin alveolar membrane into adjacent capillaries, binding to hemoglobin in red blood cells. Hemoglobin then carries oxygen through the bloodstream to body tissues and cells, where it is released to support cellular respiration and energy production.
