Glyoxysomes are present in

The correct option is palisade cells of leaf.

Step-by-step Explanation:
1. Understanding Glyoxysomes: Glyoxysomes are specialized plant peroxisomes (microbodies) that contain the key enzymes of the glyoxylate cycle, such as isocitrate lyase and malate synthase. These enzymes allow the conversion of stored fats into carbohydrates (gluconeogenesis).
2. Occurrence in Plants: While glyoxysomes are most prominent in fat-storing tissues of germinating seeds, microbodies are dynamic organelles. In the green cells of leaves, particularly the palisade cells of the leaf mesophyll, microbodies function predominantly as peroxisomes involved in photorespiration.
3. Functional Transition: During specific physiological states, such as leaf senescence or light-induced developmental transitions, the microbodies within the palisade cells can exhibit glyoxysomal activity to assist in mobilizing lipids from cellular membranes. Therefore, glyoxysomal activity and the organelles themselves can be present in the palisade cells of the leaf.
