What do all cells in a multicellular organism have in common?
All multicellular organisms have organelles like nucleus, cell membrane, endoplasmic reticulum, mitochondria,vacuole, Golgi complex etc in common. All multicellular organisms have differentiated cells which carry out specific functions.
What do all of the organisms have in common multicellular eukaryote?
All multicellular organisms are eukaryotes. Both prokaryotic and eukaryotic cells have structures in common. All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. The plasma membrane, or cell membrane, is the phospholipid layer that surrounds the cell and protects it from the outside environment.
Do all cells in a multicellular organism have the same genome?
All of the cells within a complex multicellular organism such as a human being contain the same DNA; however, the body of such an organism is clearly composed of many different types of cells. The answer lies in the way each cell deploys its genome.
What are the similarities and differences between organisms in the three domains of life?
A difference between all three domains is what their cell walls contain. A cell wall in domain Archaea has peptidoglycan. The organisms that have a cell wall in domain Eukarya, will have a cell wall made up of polysaccharides. A cell wall in domain Bacteria contains neither peptidoglycan or polysaccharides [13b].
Which two domains are the most closely related?
Recent evidence indicates that Archaea and Eukarya are more closely related to each other than either is to Bacteria. According to the evidence, all three domains of life share a common ancestor that probably existed more than 3 billion years ago (bya). Two lines of descent emerged from this ancestor.
What are the major types of protists?
Protists are typically divided into three categories, including animal-like protists, plant-like protists, and fungus-like protists. Protists vary in how they move, which can range from cilia, flagella, and pseudopodia.
