10 Questions
What characterizes the rough endoplasmic reticulum (RER)?
Presence of membrane-bound ribosomes
Why are ribosomes not a stable part of the RER's structure?
They are constantly being bound and released from the membrane
What is the main function of the rough endoplasmic reticulum in cells?
Producing secreted proteins
What distinguishes the RER morphologically?
Flattened-like membrane sheets called cisternae
Which process involves separating very fine insoluble solids from a liquid?
Churning
In which process are grains separated from their stalks by beating them?
Threshing
Which method is used to manually separate stones from grains of rice?
Handpicking
What is the purpose of churning as described in the text?
Separate very fine insoluble solids from a liquid
In the context of winnowing, what happens to the lighter solids (husks) when separated from the heavier solids (grains)?
They are carried by wind and form a separate heap
How does handpicking help in distinguishing a stone from a grain of rice?
By singling out stones that are noticeably distinct from rice grains
