Thermistor has negative temperature coefficient.

Can anyone please explain what is the use of rheostat, potentiometer, photoconductive cell ?

Thermistor is a kind of resistor depends upon the coefficient it provides resistance.
1. PTC- if temperature is increased resistance also increases.
2. NTC- if temperature is increased resistance also decreases.

Note that the question is which one is designed to be sensitive to temperature. And it is thermistor. i.e. , it is designed with the motto to be temperature Sensitive.
However the others may have the sensitivity with temp in practical cases. But they not intendedly designed to be sensitive.

Thermal + resistor = thermistor.
Here thermal indicate that resistor is temperature coefficient.
When temperature increase resistance decrease.

If temperature increases, resistance value decreases hence it is negative temperature coefficient.

Rheostat and potentiometer are almost the same. They are variable resistors whose value can be changed by us and does not depend on external parameters.
Photo conductive cells depend light. Similar to LDRs.

Thermistor is a special type of resistor thermal + resistor it is use to measure temperature.
