Living things or organisms that are made up of one cell are called unicellular or single-celled organisms.

What are examples of the cell theory?

Cell theory says that cells are the smallest unit of life. In other words this means that you cannot break down a cell into smaller parts and still call it living. For example you can break down a whole organism such as a human into smaller components like organ systems organs and tissues.

Who modified cell theory?

Rudolf VirchowTherefore later in the year 1855 a scientist named Rudolf Virchow modified this cell theory and stated that new cells are formed from the pre-existing cells i.e. Omnis cellula-e cellula. Thereby he modified the cell theory and gave final shape to the cell theory.

What is not part of the cell theory?

it is accepted that cells contain DNA in chromosomes and RNA in the nucleus and cytoplasm but only in the modern cell theory. the classical cell theory does not include this. … though prokaryotes (e.g. bacteria) contain DNA they lack a nucleus.

Why do you think there are three basic structures common to all cell types?

Why do you think there are three basic structures common to all cell types? … The cell needs materials to enter and exit needs to have a liquid medium for the transport of materials and needs a place for the storage of DNA. How are the functions of prokaryotic cells controlled without a nucleus?
