Senescence is the period between maturity and death; as it relates to tissue culture this is the phase when confluence has been reached (assuming anchorage-dependant cells) and when the media contents contain waste and/or factors to an extent which causes the cells to begin to die-off en masse. The point of tissue culture, typically, is to avoid the senescence phase by regularly changing the media (to dispose of waste products which have toxicity effects), and by subculturing while in log-phase (before the chemical signalling that can cause senescence begins).

Define the step of endocytosis?
the process by which a cell uses energy to surround a particle and enclose the particle in a vesicle to bring the particle into the cell is called endocytosis: the cell comes into contact with particle the cell membrane begins to wrap around the particle then the particle is bought into the cell

What is the scientific definition of tissues?
The scientific definition of tissue culture originally meant the growth and maintenance of tissue pieces. Now it is more commonly referring to the technique of the cell culture.
What is the scientific definition of tissue culture?

What is tissue culture treated cell culture plate?
A tissue culture treated cell culture plate is a specialized plastic plate that has been treated to promote the adherence and growth of cells, particularly for use in cell culture experiments. The treatment usually involves coating the surface with materials such as collagen or gelatin to enhance cell attachment and growth, providing a more suitable environment for cell culture. This type of plate is commonly used in research laboratories for growing cells in vitro.
