They arent alive
The cell theory states that all living organisms are composed of one or more cells, and that the cell is the basic unit of life. Viruses, while they exhibit some characteristics of living cells, such as the ability to replicate and evolve, are not composed of cells and cannot carry out metabolic processes independently. Therefore, they do not meet the fundamental criteria of the cell theory, which is why they are not classified as living organisms.

The type of cells that viruses live in are host cells. Viruses need host cells in order to reproduce or multiply.
Yes, an organelle is a cellular component that is included as part of a cell. Organelles have different functions and are responsible for carrying out specific tasks within the cell. Examples of organelles include the nucleus, mitochondria, and chloroplasts.
The cell theory became an accepted part of biology in the 19th century. Rudolf Virchow, Matthias Schleiden, and Theodor Schwann are credited with contributing to the development and acceptance of the cell theory during this time period.
Viruses are not considered part of the cell theory because they are acellular entities that require a host cell to replicate.
Latent Viruses: some viruses can be latent. That means that after the virus enters a cell, its hereditary material can become part of the cell's hereditary material.

None. Viruses are acellular. Many biologists do not consider viruses to be living things in part because they are acellular. Look at any phylogeny (tree of life). Viruses are not on them.

Lysosomes
This is something all viruses do in effect when they attack a cell and make the cell start producing new viruses as a part of their reproductive process. See the related question below about the Lytic Cycle which describes the steps in that process.

No. The RNA/DNA is in-cased in the "capsid". This is not the same thing as a cell wall.Edit: a cell wall - as the name implies - is a part of a cell. Viruses are not cells. Cells are living, viruses are not. Cells are also much larger in size - a virus to a cell could be roughly compared to a man standing next to the Empire State Building.
That statement is part of cell theory, which is summarized as follows:Living organisms are composed of one or more cells.Cells are the most basic unit of life.Cells come from other living cells which preceded them.
