cyclosis
Very LowTechnical / Scientific
Definition
Meaning
The circular streaming movement of cytoplasm within a plant or animal cell.
In biological contexts, it refers to the internal, rotational flow of the living contents of a cell, particularly observed in large plant cells like those of algae. It can also refer more generally to a circular motion within a fluid system.
Linguistics
Semantic Notes
The term is almost exclusively used in biology, specifically cell biology and botany. It denotes a specific, observable cellular process and is not used metaphorically in standard language.

Examples
By Part of Speech
verb
British English
- The cytoplasm was seen to cyclose around the vacuole.
- The process is known as cyclosing.
American English
- The cytoplasm was observed to cyclose rapidly.
- Cyclosing facilitates nutrient distribution.
adverb
British English
- The particles moved cyclotically.
- The stream flowed cyclotically around the nucleus.
American English
- The cytoplasm circulated cyclotically.
- Chloroplasts were transported cyclotically.
adjective
British English
- The cyclotic movement was clearly visible.
- A cyclotic pattern was established.
American English
- The cyclotic flow was measured.
- Cyclotic activity increases with temperature.
Examples
By CEFR Level
- Under the microscope, we could see the green chloroplasts moving in a process called cyclosis.
- Cyclosis helps to distribute materials inside a plant cell.
- The rate of cytoplasmic cyclosis in *Elodea* can be influenced by light intensity and temperature.
- Researchers studied the mechanism driving cyclosis, focusing on the role of actin filaments and myosin motors.
Learning
Memory Aids
Mnemonic
Imagine a CYCLOne inside a cell, causing the CYCLOplasm to spin in CYCLOSIS.
Conceptual Metaphor
CELL IS A FACTORY (cyclosis is the conveyor belt moving materials).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with "циклоз" (which is a direct transliteration) or "цикл" (cycle). The concept is specifically "цитоплазматическое движение/ток".
Common Mistakes
- Spelling as 'cyclosos' or 'ciclosis'.
- Using it to refer to any circular motion outside a biological cell.
- Incorrect pluralisation ('cyclosises'); correct plural is 'cycloses'.

FAQ
Frequently Asked Questions
Its primary function is to circulate nutrients, organelles, and other materials efficiently within the cell, aiding in distribution and metabolic processes.
It is predominantly observed in large plant cells, algae, and some protozoa. While cytoplasmic streaming occurs in some animal cells (e.g., amoebae), the term 'cyclosis' is most strongly associated with plant cell biology.
Cyclosis is driven by the cytoskeleton, specifically motor proteins (like myosin) moving along tracks of actin filaments, pulling the cytoplasm along.
Yes, in suitable specimens like leaf cells from the aquatic plant Elodea, cyclosis is clearly visible at medium to high magnification under a light microscope.
