5 Questions
What are the three main principles of the cell theory?
The three main principles of the cell theory are: 1) All living things are made of cells, 2) Cells are the basic structural and functional units of organisms, and 3) All cells come from pre-existing cells.
What are unicellular organisms and provide examples?
Unicellular organisms are organisms made up of only one cell. Examples of unicellular organisms include bacteria, protozoa, unicellular algae, and unicellular fungi or yeasts.
What are multicellular organisms and how do their cells coordinate?
Multicellular organisms are organisms made up of more than one cell, such as humans and dogs. The cells in a multicellular organism coordinate with each other in order to regulate the various functions of the body. They may perform different roles, such as nerve cells, skin cells, blood cells, and bone cells.
What are the main differences between prokaryotic and eukaryotic cells?
Prokaryotic cells are much smaller and simpler than eukaryotic cells. They lack membrane-bound organelles. Prokaryotes are divided into two groups: Archaea and Bacteria. Prokaryotic cells divide by binary fission. On the other hand, eukaryotic cells are more complex, containing membrane-bound organelles. They include cells of plants, animals, and fungi.
What are the four main structures found in prokaryotic cells?
The four main structures found in prokaryotic cells are: 1) Cell membrane, 2) Cytoplasm, 3) Ribosomes, and 4) Genetic material (DNA or RNA).
