It's often used in biology to describe plants that have fleshy, water-storing tissues to survive in arid environments.
Therefore, "succulenta" is not a stand-alone word in English, but rather a part of the word succulent, which describes a plant that has these water-storing tissues.
Here's how it works:
* Succulenta (Latin): Juicy, succulent
* Succulent (English): A plant with fleshy, water-storing tissues.
So, if you hear someone say "succulenta," they are probably referring to a succulent plant.
