Cactus:

1. Cactus is a succulent belonging to the family Cactaceae.
2. It has modified leaves into spines to reduce water loss via transpiration (loss of water through stomatal pores due to evaporation).
3. Cactus is a gymnosperm (seed-bearing vascular (presence of xylem and phloem for transport of water and food) organism.
4. It is an autotrophic organism, hence can produce food via photosynthesis using photosynthetic pigments such as chlorophyll to harness sunlight.
