How do plants get rid of their solid wastes?

Answer 1

Plants do not excrete waste materials from their cells at all. Instead, plant cells possess an organelle (a cell sized organ) called a Central Vacuole in which the plant cell deposits all waste products from chemical processes within the cell. The central vacuole is filled with waste products until either the cell or the plant dies, it does not "excrete" any sort of waste.

Alternately you can look at it this way: Sugar is one of the factors of plant waste. The plant stores that, and uses it for energy. Second is oxygen. Oxygen escapes by cells called guard cells. When the stomata (the space between the guard cells) gets full, the guard cells swell open and release extra water, and oxygen.

Answer 2

Plants typically release solid wastes through the shedding of leaves, flowers, and fruits. These parts of the plant contain waste products and are eventually dropped from the plant. Additionally, some plants store waste substances in specialized structures like resin ducts or bark that are later shed or removed.

Answer 3

Most plants do not have solid wastes. Only those plants that eat insects have solid wastes. The venus fly trap and sundew let the rotted bodies of insects fly away in the wind when they open up. In the pitcher plant, the rotted bodies decompose in the bottom of the water trap. Plants that do not eat insects do not have any solid wastes to get rid of. They get their nutrients from the soil with their roots, they also take in water, and take in carbon dioxide and give off oxygen. They do not have solid wastes.

Answer 4

I have been observing that the hominids in this vicinity tend to carry large containers of waste materials to the edge of the nearest street every Wednesday.
