Endocytosis
Leaves
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.
In plants, substances like water, nutrients, and plant hormones are transported throughout the plant via the xylem and phloem. The xylem carries water and minerals upward from the roots, while the phloem transports sugars and other organic compounds throughout the plant.

Endocytosis
Exocytosis is the process by which large substances are moved out of the cell. This involves the fusion of vesicles containing the substances with the cell membrane, releasing the substances outside the cell.
a plant.
The substance moved into the water through osmosis. The concentration of the substances inside the dialysis bag was higher than in the water and membrane was permeable to the substances. As such, they moved from a high to a low concentration along a concentration gradient.
I n a plant the substances in sugar are cellulose,sugars which is glucose.
By dispersal of fruits and seeds of that plant
