Which organelles settle on the bottom of gravity-sensing cells?
A) vacuoles
B) nuclei
C) lysosomes
D) statoliths
E) chloroplasts
Statoliths
Small granules, often made of calcium carbonate, found within certain cells associated with the detection of gravitational orientation in plants and some invertebrate animals.
Gravity-sensing Cells
Specialized cells in organisms that detect and respond to gravity, guiding growth and movement direction.
Organelles
Specialized structures within a cell that perform distinct processes necessary for the cell's life.

Final Answer :
D
Explanation :
Statoliths are small organelles that settle on the bottom of gravity-sensing cells, helping the organism to detect changes in orientation and gravity. Vacuoles, nuclei, lysosomes, and chloroplasts do not play a direct role in gravity sensing.
