Detailed explanation-1: -The growth in plants by the addition or adhesion of parts or particles is known as accretion. During accretion, materials deposit over the surface of an existing structure. Dead organisms do not grow, but some non-living entities can increase in sizes such as rocks, mountains, stones, and crystals.
Detailed explanation-2: -noun. ac·cre·tion ə-ˈkrē-shən. Synonyms of accretion. : the process of growth or enlargement by a gradual buildup: such as. : increase by external addition or accumulation (as by adhesion of external parts or particles)
Detailed explanation-3: -Intussusception and accretion are the two types of growth. When there is addition of material and formation of the cells inside the organism, the growth is known as intussusception. The increase in size due to deposition of material on the external surface is known as extrinsic growth or accretion.
Detailed explanation-4: -Accretion is the process where small particles of dust, gas, and ice collect and stick together gradually. Gravity attracts these particles together, and they continue to accumulate to form a larger mass.
