Why do scientists believe that prokaryotes existed earlier than eukaryotes?
Prokaryotic cells are much simpler than eukaryote because they are one cell organisms. They probably were here first because they didn't need as much to survive.
What is untrue of eukaryotic cells They have A true nucleus with chromosomes B smaller ribosomes than in prokaryotic cells C mitochondria D organelles in the cytoplasm E membrane-bounded compartments?
Eukaryote cells have membrane-bound organelles. One thing that is not true of eukaryote cells is they contain ribosomes that are smaller than those of prokaryotic cells. Gas vacuoles are present
What is the difference between prokaryote and eukaryote?
In procaryotes there will be no true membrane bound nucleus (nucleolus) and Chromosomes are circular form. In Procaryotes contains 70s ribosomes. In Eucaryotes true membrane is present around nucleus, and contains more than one chromosome which are linear. In Eucaryotes ribosomes are 80s . In Eucaryotes Mitochondria, Golgi Apparatus, Chloroplasts, Endoplasmic Reticulam, Lysosomes are present . But those are absent in Procaryotes.
Which types of Cells contain ribosomes?
Ribosomes are responsible for one of the most fundamental processes required for cells to live. Without ribsomes, they couldn't translate the genetic code into proteins which can carry out reactions that do not occur spontaneously (i.e. without a little "encouraging push").Hence, all cells contain ribosomes. In fact, we only know two major categories of ribosomes - 80S and 70S ribosomes. 80S are larger and found in eukaryote cells (yeast, fungi, animals, plants), while 70S are smaller and found in prokaryotes (archaea, bacteria - but also mitochondria and plastids inside eukaryotes! This is a strong argument in favour of the "endosymbiont theory").
Are prokaryotic cells and eukaryotic cells similar?
No, they are not... an example would be this; a type of prokaryote is bacteria, a type of eukaryote is a wolf (animals are classified as a eukaryote) Obviously the wolf is bigger than the bacteria.
Is the ribosome a eukaryote or a prokaryote?
The ribosomes are in both eukaryote and prokaryote cells, but the subunits are different from domain to domain. That is one of the attack routes of epidemiology. To attack the prokaryote ribosomes with a substance that does not affect eukaryote ribosomes.
Is an arthropod a eukaryote or a prokaryote?
Since they have more than one cell, the cells in them are eukaryotes. Prokaryotes are bacteria and insects are have to have eukaryotic cells.
What cell do all eukaryote cells contain?
Living cells have cell membranes, genetic material & ribosomes in COMMON. 1. Eukaryotes have membrane bound organelles. 2. They are much larger to hold these organelles. 3. They have more than one chromosome 4. Often are multicellular 5. Have peroxisomes and lysomes 6. Have mitochondria 7. Larger ribosomes

Are cheethas eukaryotic?
All animals are eukaryotes. In fact, anything within the domain Eukaryota is a eukaryote. This includes animals, plants, fungi, and others. Biology classifies everything into two domains: one for eukaryotes and one for prokaryotes. Prokaryotes are almost exclusively unicellular, although it is believed there are some multicellular prokaryotes. Eukaryotes can be either unicellular or multicellular.Answer is Yes, obviously.

Eukaryote cells have membrane-bound organelles. One thing that is not true of eukaryote cells is they contain ribosomes that are smaller than those of prokaryotic cells. Gas vacuoles are present
Is a dragonfly eukaryote?
No. Bees are Eukaryotes, because they have more than one cell to make it an organism. Prokaryotes are single-celled organisms.
Is it true that both prokaryote and eukaryote organisms have more than one cell?
Eukaryotes can be single-celled or multicellular. To the best of my knowledge prokaryotes don't even form synergistic colonies.
How many units do ribosomes function as?
Two part units. There are two compartments.A larger one and a smaller one
Why is protein different in prokaryotes and eukaryotes?
In prokaryotes, DNA is stored in the cytoplasm. also prokaryotes have no nucleus In prokaryotes, transcription and translation happen at the same time.
What are ribosomes shaped like?
Ribosomes are made of two subunits; one larger and one smaller. It is made up of proteins and has a globular shape. This is so that mRNA can pass through during translation.
What are the basic differences between prokaryic and eukaryotic?
Prokaryotes do not have a nuclear membrane or nucleoli, Eukaryotes do. Prokaryote have no organells, Eukaryote do. Prokaryotes usually have a single circular chromosome lacking histones. Eukaryotes have multiple linear chromosomes with histones. Prokaryotes replicate by binary fission, Eukaryotes by mitosis and meiosis.
