Sieve Elements

Science / Biology / Sieve Elements: Tubular, thin-walled cells that form a system of tubes extending from the roots to the leaves in the phloem of plants; lose their nuclei and organelles at maturity, but retain a functional plasma memb MORE

Schwann Cells

Science / Biology / Schwann Cells: Specialized glial cells that form the myelin sheath that coats many axons. Cells surrounding the axons of some neurons, thus forming the myelin sheath. MORE

Plasma Cells

Science / Biology / Plasma Cells: Cells produced from B cells that synthesize and release antibodies. MORE

Molecular Sieve

Science / Chemistry / Molecular Sieve: A material that contains many small cavities interconnected with pores of precisely uniform size. Zeolites are an example. Molecular sieves adsorb molecules that are small enough to pass through their MORE

Sieve Plates

Science / Biology / Sieve Plates: Pores in the end walls of sieve elements that connect the sieve elements together. The end walls of sieve tube cells that are perforated (sieves). MORE
