A sieve tube is a type of long, narrow cell found in the phloem of vascular plants. They are responsible for transporting sugars and other nutrients throughout the plant. Sieve tubes are connected end-to-end to form sieve tube elements that allow for the efficient movement of substances.
Seive tube of the phloem
Seive cells have a nucleus.Seive tube elements do not have a nucleus.
There are cells without mitochondria.Some are erithrocytes,seive tube elements etc
Some cells like seive tube elements lack.Other cells have a nucleus.
Most of eukariyotic cells have only one nucleus.But some cells have more than one nucleus. Eg:-Skeletal muscle cells.Some cells do not have a nucleus.Eg:-Erythrocytes,Seive tube elements
The Phloem.
Seive tube of the phloem
Seive cells have a nucleus.Seive tube elements do not have a nucleus.
They are prokariyotic cells.Also erithrocytes and seive tube elements do not have.
Prokariyotes lack a nucleus.Mamalian erythrocytes,seive tube elements also lack.
There are cells without mitochondria.Some are erithrocytes,seive tube elements etc
Perhaps Enormusly Networks Engage Sever
Some cells like seive tube elements lack.Other cells have a nucleus.
Of course they have. Mitocondria pesent in every living plant cell except seive tube elements
Typical eukariyotes have a nucleus.But red blood cells of mammals,seive tube elements lack a nucleus.
Yes,they are in both.They are almost in every eukariyotic cell accept RBC,phloem seive tube cells etc
