What else can I help you with?
Are both chloroplasts and mitochondria bounded by two membranes?
Yes. The outer membrane is similar to modern eukaryotic membranes, such as the plasma membranes of animals and plants. The inner membrane is similar to modern prokaryotic membranes, found in bacteria. This difference has been taken as one piece of evidence to support the theory of the endosymbiotic origin of these two organelles, i.e. the idea that each of these organelles formed originally from the engulfing of a prokaryotic cell by a eukaryotic one.
What Bacteria do not have?
Bacteria do not have a nucleus or membrane-bound organelles such as mitochondria or chloroplasts. They also do not have a true cell wall made of cellulose like plant cells.
Are onion cells prokaryotic or eukaryotic?
Onion cells are eukaryotic. Eukaryotic cells have a true nucleus enclosed by a membrane, as well as other membrane-bound organelles like mitochondria and chloroplasts. This distinguishes them from prokaryotic cells, which lack these membrane-bound structures.
What is a prokaryote where is the genetic material found in prokaryote?
A prokaryote is a unicellular organism that lacks a true nucleus and membrane-bound organelles. In prokaryotes, the genetic material (DNA) is found in a region of the cell called the nucleoid, which is not enclosed by a nuclear membrane.
Eukaryote s lack a nucleus and other membrane organelles?
No, eukaryotes do have a true nucleus and organelles. What you're describing is a prokaryote.
Are both chloroplasts and mitochondria bounded by two membranes?
Yes. The outer membrane is similar to modern eukaryotic membranes, such as the plasma membranes of animals and plants. The inner membrane is similar to modern prokaryotic membranes, found in bacteria. This difference has been taken as one piece of evidence to support the theory of the endosymbiotic origin of these two organelles, i.e. the idea that each of these organelles formed originally from the engulfing of a prokaryotic cell by a eukaryotic one.
What type of cell is a eukaryotic cell?
A eukaryotic cell is a type of cell that has a true nucleus enclosed by a membrane, along with other membrane-bound organelles such as mitochondria and Golgi apparatus. These cells are typically larger and more complex than prokaryotic cells.
What Bacteria do not have?
Bacteria do not have a nucleus or membrane-bound organelles such as mitochondria or chloroplasts. They also do not have a true cell wall made of cellulose like plant cells.
Is the following sentence true or false Both chloroplasts and mitochondria are enclosed by two envelope membranes?
True. Both chloroplasts and mitochondria have a double-membrane envelope that surrounds their organelle structures.
What characteristics do all eukaryotic cells have in common?
All eukaryotic cells have a true nucleus bound by a nuclear membrane, membrane-bound organelles such as mitochondria and endoplasmic reticulum, and a cytoskeleton for structural support and cell movement. They also typically have linear chromosomes made of DNA.
Describe a cell in the domain eukarya?
A cell in the domain Eukarya is characterized by having a true nucleus enclosed by a nuclear membrane. It also typically contains membrane-bound organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus. Eukaryotic cells have a more complex structure compared to prokaryotic cells, which lack a true nucleus and membrane-bound organelles.
Are fungi cells eukaryotic or prokaryotic and why?
Fungi cells are eukaryotic because they have true nuclei with a nuclear membrane, as well as other membrane-bound organelles like mitochondria and Golgi apparatus. Prokaryotic cells, such as bacteria, lack these features and have a simpler cellular structure.
What don't bacteria have?
Nucleus
Are onion cells prokaryotic or eukaryotic?
Onion cells are eukaryotic. Eukaryotic cells have a true nucleus enclosed by a membrane, as well as other membrane-bound organelles like mitochondria and chloroplasts. This distinguishes them from prokaryotic cells, which lack these membrane-bound structures.
What do eurkaryotic cells have that prokaryotic cells do not?
Eukaryotic cells have a true nucleus containing their DNA, membrane-bound organelles such as mitochondria and endoplasmic reticulum, and are generally larger and more complex than prokaryotic cells. Prokaryotic cells lack a nucleus and membrane-bound organelles, and their DNA is typically found in a region called the nucleoid.
Eukaryotes usually contains?
Eukaryotes usually contain a true nucleus bound by a nuclear membrane, membrane-bound organelles such as mitochondria and endoplasmic reticulum, and linear chromosomes composed of DNA associated with histone proteins. They can be single-celled organisms like protists or multicellular organisms like plants, animals, and fungi.
What is is the difference between prokaryotic and eukaryotic cells?
eukaryotic cells have a true nucleus and membrane-bound internal organelles. basically this means that eukaryotic cells organelles do not float around but have a specific spot in the cell. the organelles in a eukaryotic cell are each surrounded by a membrane isolating the organelle from the rest of the organelles. prokaryotic cells lack a true nucleus and do not have membrane-bound internal organelles. basically this means that prokaryotic cells have SOME organelles but the organelles that they do have float around. Most prokaryotes are single-celled organisms such as bacteria.
