1. Adaptation in a plant

I'm just chillin' with a cactus

Definition: Adaptations in plants are special features that allow the plant to live in certain environments and habitats. These adaptations eventually spread through populations in order to ensure the survival of the species.

What the specimen is: "Chin Cactus"
or Gymnocalycium mihanovichii

Where we found it: This little guy is a common house plant, and currently resides in Sarah's bedroom. His species is originally from South America.

How it relates to adaption in a plant: Cacti in general need to be able to withstand hot climates with little rainfall. They developed needles instead of leaves because these spines don't lose water as quickly as leaves do. The needles also protect the plant from predators looking to eat the cactus as a source of water or food. Cacti adapted with these traits over the years in order to ensure survival.
