Plant Physiology & Nutrition in Plants Questions with Solutions

7 questions5 easy2 medium

This topic covers how plants live and grow: photosynthesis, transpiration, respiration in plants, the transport of water and food through xylem and phloem, plant hormones, modes of nutrition in plants, and plant tissues. Questions usually ask what is needed for photosynthesis and what it produces, where it takes place (in the chloroplasts), which tissue carries water (xylem) and which carries food (phloem), and what each plant hormone does, such as auxins for growth and ethylene for fruit ripening. Insectivorous plants such as the pitcher plant are also commonly tested. Practise the plant physiology questions below, written in the style of the general awareness sections of exams such as SSC, banking, railways, CUET GAT, MAH CET and CLAT. Each question comes with a detailed explanation that adds related facts, so every question helps you revise more than one point.
