What is the difference between prokaryote and eukaryotes?
Prokaryotic cells are an organism with a cell that lacksinternal structures surrounded by membranes and usually single celled. Eukaryotic cellscontain internal bound structures and are usually multi cellular.
What is Golgi body?
Golgi bodies are stacked, flattened membranes which sort proteins and other cellular substances and package them into membrane-bound structures called vesicles.
Not found in prokaryotic cells?
A eukaryote is an organism whose cells contain complex structures enclosed within membranes. For prokaryotic cells it is the opposite.
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.
Do prokaryote cells contain organelles?
They do but the organelles are not bound in membranes.
Does the eukaryote membrane bound organelles?
the membranes of eukaryotes form organelles. E.g. endoplasmic reticulum is made of membranes.
which of the following body structures protects against disease by trapping pathogens?
The mucous membranes lining the nose, mouth, lungs, and urinary and digestive tracts provide another nonspecific barrier against potential pathogens. Mucous membranes consist of a layer of epithelial cells bound by tight junctions.
What is flattened membranes called?
Flattened membranes are typically referred to as "cisternae." Cisternae are a series of stacked, membrane-bound structures found within organelles such as the endoplasmic reticulum and the Golgi apparatus. They play crucial roles in processes like protein and lipid synthesis, processing, and transport within cells.
Are regions of cell membranes tightly bound together?
Yes, regions of cell membranes can be tightly bound together through structures like tight junctions. Tight junctions are specialized protein complexes that seal adjacent cells together, preventing the passage of molecules between them. This tight binding is crucial for maintaining tissue integrity and regulating the movement of substances across the cell membrane.
What are the names for membranes with hair-like structures on them?
cilia
Do Golgi bodies have membranes?
Yes, since it is composed of membrane-bound sacs.
Membrane bound structures that performs a specific job?
Membrane-bound structures within a cell are known as organelles, and they perform specific functions essential for the cell's survival and operation. Examples of organelles include the mitochondria, which generate energy through cellular respiration, and the endoplasmic reticulum, which is involved in protein and lipid synthesis. These structures are enclosed by lipid membranes, allowing them to maintain distinct environments necessary for their specialized tasks. Overall, organelles contribute to the overall functionality and efficiency of the cell.
