What structure will you find in a prokaryotic cell?
The prokaryotes are a group of organisms that lack a membrane-bound nucleus. Their DNA consists of a single chromosome which is in direct contact with the cytoplasm.
What structures are used for direct Cell to Cell signalling?
Desmosomes are (inter-Cellular) bi-lipid layer conjoining structures that probably have a 'hollow center channel' that permits the transit of signal [signalling] molecules.
The part of the cell that is in most direct contact with the environment is the?
The cell membrane, which surrounds the cell and is responsible for which molecules are allowed to diffuse into or out of the cell and which molecules are impermeable to the membrane
How do structures within cell allow the cell to be specialized?
The structures allow the cell to perform specific functions.
Why can protozoans get by without a respiratory system?
They are in direct contact in their environment so they can diffuse nutrients right through their cell membrane very easily causing them not to need a respiratory system.
What structures are found in plants but not animals?
The structures found in plants and not in animals are cell wall, chloroplasts and plastids.
What structures are presents in an animals cell but not plant cell?
it is the organ cell.
What are two structures that plant cell have that animals cell do not?
A cell wall and chloroplasts.
What are two cell structures that are in plants but not animals?
Cell wall and chloroplast
What structures are found in an animals cell but not a plant cell?
Animal cells have centrioles.
What structures are found in animals cell but not in plants cell?
Animal cells have centrioles.
What structures are present in an animals cell but not in a plant cell?
i think the answer would be centriole
What cell structures to plant in animals not have in common?
Cell wall, centrioles and chloroplasts
What is the part of the cell that is in most direct contact with the enviorment?
The cell membrane.
What structures are found in animals but not in plant cells?
all structures, excluding chloroplasts and cell walls
What structures would normally be found in a plant cell but not in an animal cell?
Plants have a CELL WALL where animals do not.
What structures are found in animals cells but not plant cells?
all structures, excluding chloroplasts and cell walls
