Plants excrete waste substances into the soil, store waste in vacuoles, and utilize dead cells and tissue loss, such as shedding leaves, to manage waste effectively.
What strategies do plants employ for excretion, and how do they utilize dead cells and tissue loss for waste management?

Plants employ several strategies for excretion. They excrete excess salts through glandular trichomes or accumulate them in older leaves, which are later shed. Plants also store waste products in vacuoles or deposit them in bark or wood. Dead cells and tissue loss contribute to waste management. The shedding of leaves, bark, or older tissues allows plants to dispose of metabolic by-products, minerals, and other waste. This process, known as abscission, helps maintain the health of the plant by eliminating older or damaged structures and promoting nutrient recycling.
