Endoplasmic reticulum

...he ER consists of an extensive membrane network of tubes and cisternae (sac-like structures). The membrane encloses a space, the cisternal space (or internal lumen) from the cytosol . This space is acting as a gateway. Parts of the ER membrane are continuous with the outer membrane of the nuclear envel...

...tubes, it is not unusual for sap in adjacent sieve tubes to be flowing in opposite directions. Phloem tissue consists of sieve-tube members and companion cells . The sieve-tube elements are large, cylindrical cells, with large pores in the cell wall at either end. They are almost entirely dead, and...
