Which best describes a difference between prokaryotic cells and eukaryotic cells?
Eukaryotic cells contain organelles that are enclosed in membranes
Are membranes a subcellular structure?
Yes, membranes are a subcellular structure found in cells. They are thin, flexible barriers made up of lipid bilayers that separate the internal environment of cells from the external environment. Membranes play crucial roles in regulating the passage of substances in and out of cells, compartmentalizing cell organelles, and facilitating cell communication.
Are cell membranes in prokaryotic and eukaryotic cells different in structure and function?
Yes, cell membranes in prokaryotic and eukaryotic cells have similar structures but differ in some aspects of their functions. Prokaryotic cell membranes lack membrane-bound organelles, while eukaryotic cell membranes contain them. Both types of cell membranes regulate the passage of substances in and out of the cell, but eukaryotic cell membranes are more complex due to the presence of organelles.
In what organelles does osmosis occur?
Osmosis primarily occurs in the cell's membrane (plasma membrane) and in the membrane-bound organelles such as the endoplasmic reticulum, Golgi apparatus, and vacuoles, where water molecules move across the membranes to maintain the cell's internal balance.
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.
Plasma membranes that have been isolated from red blood cell are not contaminted by internal cell membane?
Plasma membranes isolated from a red blood cell will not be contaminated with internal cell membrane (i.e. membrane from cell organelles - small structures found within cells) because red blood cells do not contain any organelles, so there will be no 'internal membrane' to contaminate.
Do prokaryote cells contain organelles?
They do but the organelles are not bound in membranes.
What cells have internal membranes and plasma membranes?
Eukaryotic cells.
What type of cell dose not have any membrane bound organelles?
Prokaryotic cells do not have membrane bound organelles.
Do Eukayote cells have membrane bound organelles?
Yes, the organelles in eukayote cells are wrapped in membranes.
Which best describes a difference between prokaryotic cells and eukaryotic cells?
Eukaryotic cells contain organelles that are enclosed in membranes
Characteristics of animal cells include what?
compartmentalized membranes ( organelles ) and a defined nucleus.
What cells has the greatest number of different cellular organelles made of membranes?
Plants
What kind of membranes do human cells have?
Human cells have a plasma membrane, which is a phospholipid bilayer that separates the cell's internal environment from the external environment. Additionally, human cells also have various organelles that are surrounded by membranes, such as the nucleus, mitochondria, endoplasmic reticulum, and Golgi apparatus.
Do eubacteria have mitochondria?
While eubacteria may lack the organized organelles found in eukaryotic cells, many eubacteria have specialized internal membranes. Cyanobacteria, for example, have membranes that contain chlorophyll and other chemicals required to carry out photosynthesis.
Do plants or animals have the greatest number of different cellular organelles made of membranes?
Animals have a greater number of different cellular organelles made of membranes compared to plants. This is because animal cells have specialized organelles such as lysosomes and centrioles, in addition to the organelles common to both plant and animal cells like mitochondria and endoplasmic reticulum.
Why animals included under eukaryotes.?
A eukaryote is any organism whose cells contain a nucleus and other organelles enclosed within membranes. Since animal cells contain a nucleus and other organelles enclosed within membranes, they're eukaryotes.
