Centrioles are absent in prokaryotes because prokaryotes use binary fission instead of mitosis. Binary fission is when a prokaryote chromosome has a DNA molecule that first replicates then attaches all copies to different parts of the cell membrane. When the cell splits, the original and replicate chromosomes split apart and the they each have duplicate DNA.
What else can I help you with?
Name the cells in which endoplasmic reticulum is absent?
Red blood cells do not have endoplasmic reticulum.
Why does not cyclosis occur in prokaryotic cells?
Cyclosis, or cytoplasmic streaming, primarily occurs in eukaryotic cells due to their complex cytoskeletal structures that facilitate the movement of organelles and materials within the cell. Prokaryotic cells, on the other hand, lack a defined cytoskeleton and membrane-bound organelles, which limits their ability to organize and transport cellular components in the same dynamic way. Additionally, the relatively simple and smaller structure of prokaryotic cells does not necessitate the same level of internal movement as seen in eukaryotes.
Is the ribosome absent in a prokaryotic cell?
No, ribosomes are in prokaryote cells and doing the job of synthesizing proteins.
Do euckaryotic cells have that prokaryotic cell do not?
Eukaryotic cells have membrane-bound organelles, such as a nucleus, mitochondria, and endoplasmic reticulum, which are absent in prokaryotic cells. Additionally, eukaryotic cells typically have a more complex structure, including a cytoskeleton and larger size. They also often have multiple linear chromosomes, whereas prokaryotic cells generally contain a single circular chromosome.
How are eukarotic cells different from Prokaratic cells?
Eukaryotic cells are characterized by having a defined nucleus that houses their genetic material, while prokaryotic cells lack a true nucleus and have their DNA located in a nucleoid region. Additionally, eukaryotic cells contain membrane-bound organelles, such as mitochondria and the endoplasmic reticulum, which are absent in prokaryotic cells. Eukaryotic cells are generally larger and more complex, often forming multicellular organisms, whereas prokaryotic cells are typically unicellular and simpler in structure.
What types of cells fall into prokaryotic?
no membranes, DNA occurs as cyclosis, under-developed organelles
Name the cells in which endoplasmic reticulum is absent?
Red blood cells do not have endoplasmic reticulum.
Is the ribosome absent in a prokaryotic cell?
No, ribosomes are in prokaryote cells and doing the job of synthesizing proteins.
WHAT BEST DESCRIBES A DIFFERENCE BETWEEN PROKARYOTIC AND EUKARYOTIC CELLS?
Eukaryotic cells contain organelles that are enclosed in membranes
What are two features of eukaryotic cells that prokaryotic cells lack?
Eukaryotic cells have a membrane-bound nucleus that houses their DNA, a feature absent in prokaryotic cells. Additionally, eukaryotic cells contain membrane-bound organelles, such as mitochondria and lysosomes, which are not found in prokaryotic cells.
What is the most obvious difference between prokaryotic and eukaryotic?
The most obvious difference is the presence of a membrane-bound nucleus in eukaryotic cells, which is absent in prokaryotic cells. Eukaryotic cells also typically have membrane-bound organelles, while prokaryotic cells do not. Additionally, eukaryotic cells are generally larger and more complex than prokaryotic cells.
What is found in eukaryotic cells but not in prokaryotic cells A Mitochondria B Golgi apparatus C Nucleus D Cell membrane?
A Mitochondria and C Nucleus. Eukaryotic cells have membrane-bound organelles like mitochondria and a nucleus, which are absent in prokaryotic cells. The Golgi apparatus and cell membrane are found in both eukaryotic and prokaryotic cells.
What distinguishes eukaryotic cells from prokaryotic cells?
Eukaryotic cells have a defined nucleus containing their genetic material, while prokaryotic cells do not. Eukaryotic cells also contain membrane-bound organelles, like mitochondria and endoplasmic reticulum, which are absent in prokaryotic cells. Eukaryotic cells are generally larger and more complex than prokaryotic cells.
What are prokaryotic cells reproduced by?
Other prokaryotic cells
Is true of prokaryotic cells?
Prokaryotic cells do NOT have a nucleus.
What are the oldest cells on earth?
The first cells on earth were likely prokaryotic. This is because the prokaryotic cells are not complex like eukaryotic cells.
What is is the characteristic of prokaryotic cells?
Prokaryotic cells do not have a nuclear membrane.
