Plant sap
Plant sap is the fluid transported in xylem cells or phloem sieve tube elements of a plant. These fluids can be derived from two different sources, intracellular and extracellular sap.
Intracellular sap[edit | edit source]
Intracellular sap is the water inside the vacuole, which is enclosed by the tonoplast (vacuole membrane). This sap contains a variety of organic and inorganic molecules including sugars, organic acids, amino acids, and salts.
Extracellular sap[edit | edit source]
Extracellular sap, also known as latex, is a sticky milky fluid found in some plants, such as poppy, dandelion, rubber tree, aloe, and banana. It contains a variety of compounds, including alkaloids, glycosides, proteins, and polysaccharides.
Functions[edit | edit source]
Plant sap serves several functions in the plant. It is involved in nutrient transport, waste removal, and water balance. It also plays a role in plant defense against herbivores and pathogens.
