Substances leave the plant through processes such as transpiration, where water evaporates from the leaves, and translocation, where sugars and other nutrients are transported through the phloem tissue to other parts of the plant for growth and metabolism. Additionally, gases like oxygen and carbon dioxide can enter and exit the plant through tiny openings called stomata on the leaves.
Leaves
The cell membrane protects the cell and regulates what substances enter and leave the cell.
Two substances that leave the leaf through the stomata (the small openings on the leaf surface) are water vapor and oxygen. Water vapor exits the leaf during the process of transpiration, which helps regulate temperature and maintain moisture levels. Oxygen is a byproduct of photosynthesis and is released into the atmosphere as the plant converts carbon dioxide and sunlight into energy.
A plant cell has a cell membrane which controls the movement of substances in and out of the cell. :D
Plant growth substances, also known as plant hormones, regulate various aspects of plant growth and development. They work at very low concentrations throughout the plant. These substances include auxins, cytokinins, gibberellins, abscisic acid, and ethylene. They can influence processes such as cell elongation, cell division, seed germination, and fruit ripening.
Leaves
The cell organelle responsible for controlling which substances enter and leave a plant cell is the cell membrane, specifically the plasma membrane. The plasma membrane is a selectively permeable barrier composed of phospholipids and proteins that regulate the passage of molecules such as nutrients, water, and waste products. Through processes like diffusion, osmosis, and active transport, the plasma membrane maintains cellular homeostasis by allowing essential substances to enter the cell while preventing harmful substances from entering.
The cell membrane protects the cell and regulates what substances enter and leave the cell.
Inoculation of plant parts with growth-promoting substances.

a plant
IT depends on what cell. In the plant cell it is the cell wall and the cell membrane. But in the animal cell it is only the cell membrane.
So they basically just stop doing reactions and then pretty much leave it for 30 years and wait forhe radioactive substances to decay, or they bury it and leave it for like 50 years

I n a plant the substances in sugar are cellulose,sugars which is glucose.
