No, bacteria do not have tissues like multicellular organisms. They are unicellular organisms made up of a single cell.
The process that leads a single undifferentiated egg cell to develop into a complex organism is not fully understood. This process of differentiation is an area of active research. It is known that the key lies in methods of gene expression.
Mitosis occurs in organisms to ensure growth, repair, and asexual reproduction. It allows for the production of two identical daughter cells from a single parent cell, helping in the maintenance and regeneration of tissues and organisms.
All complex organisms begin as a single cell. As they divide into 2, 4, 8, 16 cells , they begin to become certain tissues. Further divisions produce organs, organ systems and then the entire organism. The study of embryology will help you to understand this process.

No. Tissues are multiple cell structures.
No. Tissues are aggregations of multiple cells, which do not occur in single-celled organisms.
No, bacteria do not have tissues like multicellular organisms. They are unicellular organisms made up of a single cell.
Tissues are made of cells that are all the same type and one cell can't be a tissue.
The name of the process where an organism develops from a single cell into many different types of cells is called "cell differentiation." This process involves cells becoming specialized to perform specific functions in the body, leading to the formation of different tissues and organs.

Developmental biology is the field that studies the processes by which a single fertilized egg (zygote) goes through cell division, differentiation, and morphogenesis to give rise to an adult organism with billions of cells. This process involves intricate regulatory mechanisms such as cell signaling, gene expression, and cell-to-cell interactions that control the growth and specialization of cells into different tissues and organs.
Yes, cells are single components in the manner that when they are collectivelly brought together they form the tissues, when the tissues are brought together they form the organs. We must however remember that, although cells are single components of tissues and thus organs, they too contain there own components, the organelles. The organelles of cells act as the systems and "organs" of an individual cell. In the absence of cellular organelles, a cell would not survive.

It depends how severe the damage is.
Mitosis occurs in organisms to ensure growth, repair, and asexual reproduction. It allows for the production of two identical daughter cells from a single parent cell, helping in the maintenance and regeneration of tissues and organisms.
