What else can I help you with?
A true nucleus is absent in bacteria and?
Instead, bacteria have a nucleoid region where the genetic material is located. This nucleoid is not surrounded by a membrane like a true nucleus found in eukaryotic cells.
Do bacterial cells have a nucleus?
bacteria do not contain a nucleus. they have their genetic material in contact with the cellular component. there is no nuclear membrane to enclose their nuclear material into a nucleus.they are devoid of compartmentalization i.e they do not have membrane bound oraganelles and as nucleus is a membrane bound organelle so it is absent. though their genetic material is still present but in contact with cytoplasm
What are the genetic differences between bacteria cells and human body cells?
One key genetic difference is the presence of a nucleus in human cells, which bacteria lack. Human cells have linear chromosomes enclosed within the nucleus, while bacteria have a single circular chromosome located in the cytoplasm. Additionally, bacteria may have plasmids, small circular DNA molecules that are often absent in human cells.
What is present and absent in plant and animal cell?
A cell wall, chloroplast and large vacuole are present in plant cell. Whereas, Golgi body and grana are present in animal cell. A cell wall is absent in animal cells and Golgi Bodies are absent in plant cells.
Do bacteria have a membrane-bound nucleus?
No, bacteria do not have a membrane-bound nucleus.
IS th cell nucleus present or absent in Monera?
It is absent.
A true nucleus is absent in bacteria and?
Instead, bacteria have a nucleoid region where the genetic material is located. This nucleoid is not surrounded by a membrane like a true nucleus found in eukaryotic cells.
What are the similarities and difference between prokaryotic and eukaryote?
Prokaryotes are most primitive organisms. All bacteria belong to thiscategory. Eukaryotes are well developed organisms. All animals and Plants including Fungi, Amoeba, Malarial parasite etc belongs to this class. Prokaryotes have single chromosome in there nucleus but eukaryotes have have multiple chromosomes in there nucleus. Prokaryotes do not have His-tone protein present in there Chromosomes. While it is present in Eukaryotes. Nucleolus is absent in bacteria but present in eukaryotes. Nuclearmembrane is absent or poorly developed in Prokaryotes and well developed in Eukaryotes. Cellorganellesare absent or poorly developed in Prokaryotes and well developed in Eukaryotes. Mitochondria are absent in Prokaryotes and present in Eukaryotes. 70S Ribosomes are present in Prokaryotes and 80S and Ribosomes are present in Eukaryotes. Bacteria have cell wall made up of Peptidoglycan (usually.) but plant cell wall is made of cellulose and animal cell do not have it. (pressure inside the gram positive bacteria are 30 times more than atmospheric pressure and that in gram negative bacteria is 5 times more. Itprobablyindicates that gram positive bacteria has originated in deep sea and gram negative in upper part of sea, where pressure is low.
What is a cell features that is absent in a bacterial cell?
Bacteria cells are prokaryotic, meaning they have no nucleus or organelles. They have 1 strand of DNA. Human, animal and plant cells are eukaryotic.
Do bacterial cells have a nucleus?
bacteria do not contain a nucleus. they have their genetic material in contact with the cellular component. there is no nuclear membrane to enclose their nuclear material into a nucleus.they are devoid of compartmentalization i.e they do not have membrane bound oraganelles and as nucleus is a membrane bound organelle so it is absent. though their genetic material is still present but in contact with cytoplasm
What has nucleus?
Nucleus is in eukariyotes.It is absent in prokariyotes.
Are fungi cell nulceus present or absent?
Fungi have a cell nucleus. Like all eukaryotic organisms, fungi have cells with a distinct membrane-bound nucleus that contains their genetic material. The nucleus is responsible for regulating the cell's activities and storing the DNA.
What two cell structures do protists have that bacteria does not?
Protists have membrane-bound organelles, such as a nucleus and mitochondria, which are not present in bacteria. Additionally, many protists possess a complex cytoskeleton that aids in maintaining cell shape and facilitating movement, a feature that is generally absent in bacterial cells. These structures contribute to the greater complexity and diversity of protists compared to bacteria.
Which organelles are present only in plant cells?
Chloroplasts are present only in plant cells.
Is rose having pistil present or absent?
In rose pistil are present or absent
Are absent and present homophone antonyms or synonyms?
No, absent and present are not homophones. Absent and present are antonyms, as absent means not being in a particular place or missing, while present means being in a particular place or existing now.
Is the fungi kingdom present or absent?
Absent
