A Botanist
A biologist is a scientist who specifically studies living organisms and their interactions with each other and their environment. A scientist is a broader term that encompasses a wide range of disciplines that involve systematic study of the natural world, including biology, chemistry, physics, and more.
Botany is the science that includes the study of plants and their life processes, structure, growth, reproduction, and interactions with the environment.
A microbiologist or medical scientist would study how bacteria are affected by antibiotics. They can investigate how bacteria develop resistance to antibiotics and explore new ways to combat antibiotic resistance.
A biologist or ecologist would typically observe organisms in the field or in a lab setting to study their behaviors, interactions, and characteristics. This helps to understand the organism's role in their ecosystem and how they are adapted to their environment.
The study of heredity and variation is called genetics. It focuses on how traits are passed down from one generation to the next, and how those traits can vary within a population. Genetics helps us understand why individuals in a species may differ from one another and how genetic information is transmitted.

A paleontologist would generally study paleontology.
The type of investigation would be fieldwork.
Botanists are people who study plants. Moss are plants, so Botanists study moss too.
A Dendrologist is the type of scientist who studies trees. Dendrology is the study of wooded plants that include trees, lianas, and shrubs. An arborist studies individual trees including tree surgery.
