Do eukaryotic cells have a flagellum?
Yes. The flagellum is a hair-like/thread-like structure that functions in locomotion. For example, the sperm cell is a eukaryotic flagella cell. The motile sperm cells move via flagellum. There are three types of flagella; archaeal, bacterial, eukaryotic.
In prokaryotic cells, both cilia and flagella are composed of microtubels?
Eukaryotic cells may have flagella or cilia. Flagella and cilia are organelles involved in locomotion and in eukaryotic cells consist of a distinct arrangement of sliding microtubules surrounded by a membrane. The microtubule arrangement is referred to as a 2X9+2 arrangement. Prokaryotic cell - Many prokaryotes have flagella, each composed of a single, rotating fibril and usually not surrounded by a membrane . There are no cilia. Short version: "False"
What is the difference between eukaryotic and prokaryotic flagella?
Difference between eukaryotes and prokaryotes :Eukaryotes have a well defined and membrane bound nucleus while prokaryotes have no well defined nucleus and no nuclear membrane.Membrane bound structures are absent in prokaryotes while eukaryotes have some membrane bound structures.Nucleolus is absent in prokaryotes while it is present in eukaryotes.Cell size is smaller in prokaryotes while it is comparatively big in eukaryotes.Cell division is usually asexual while it is sexual in eukaryotes.Mitochondria (power house of cell) is present in Eukaryotes while prokaryotes have no mitochondria. (They release energy in cytoplasm only)For locomotion Flagellum is present in some prokaryotes while cilium is present in some Eukaryotes.Endoplasmic reticulum, golgi body, lysosomes are present in Eukaryotes while it is absent in prokaryotes.Ribosomes in Eukaryotes have subunits : 60 S and 40 S which form 80S unit. Ribosomes in prokaryotes have subunits :50 S and 30S which form 70 S unit.Three layered envelope (Capsule /Slime layer, cell wall, membrane) is present in prokaryotes (Exception : Mycoplasma has no cell wall). Eukaryotes have either two layered (cell wall and membrane) ( in plants) or single layered ( only membrane) ( in animals) envelope.Due to absence of nuclear membrane in prokaryotes, genetic material keep flowing in cytoplasm. Eukaryotes, due to presence of nuclear membrane, have a fixed set of DNA and chromosomes.Pili or fimbrie is present in prokaryotes which are used in conjugation.Prokaryotes have nucleoid instead of nucleus which is in eukaryotesProkaryotic Cell :Eukaryotic cell :Thanks for reading it till the end!
Do animal cells have flagella?
They certainly do - the best example is a sperm cell. Flagella are long, hairlike structures which are located on the end of a cell and help the cell swim. Cillia are shorter structures and typically occur in bunches. Many internal membranes are lined with cillia. These help move material along the membrane.
False: in prokaryotic cells, both cilia & flagella r composed of microtubules.?
Eukaryotic.
