In response to sudden, 5 to 10°C rises in temperature, plants produce a unique set of proteins referred to as heat shock proteins (HSPs). There are five classes of heat shock proteins found in plants such as;

HSP class	Examples (Arabidopsis / prokaryotic)	Cellular location
I) HSP100	a) AtTCP-1 / GroEL, GroES	i) Cytosol
II) HSP90	b) Various AtHSP22, AtHSP20, AtHSP18.2, AtHSP17.6 / IBPA/B	ii) mitochondria
III) HSP70	c) AtHSP101 / ClpB, ClpA/C	iii) chloroplasts
IV) HSP60	d) AtHSP70 / DnaK	iv) endoplasmic reticulum
V) smHSP	e) AtHSP90 / HtpG

Match the following HSPs   with their correct location and the examples of the HSPs;
