Chloroplast are absent in root hairs because root hairs do not produce food. These are meant for absorption of water and minerals from soil. Chloroplast is the store house of chlorophyll which is the green pigment essential in photosynthesis.Moreover root and root hair are underground structures away from light, hence they do not contain chloroplasts, as chlorophyll pigments present within the chloroplasts are functional only in presence of light.

So, the correct answer is 'chloroplast'
