Unicellular definition- A unicellular organism, also known as a single-celled organism, is an organism that consists of a single cell, unlike a multicellular organism that consists of multiple cells. In contrast, even the simplest multicellular organisms have cells that depend on each other to survive.
Multicellular definition- Multicellular organisms are organisms that consist of more than one cell, in contrast to unicellular organisms.
Prokaryote definition- A microscopic single-celled organism which has neither a distinct nucleus with a membrane nor other specialized organelles, including the bacteria and cyanobacteria. In a few organisms called prokaryotes, there is no defined nucleus and the DNA is found throughout the cell.
Eukaryote definition- A eukaryote is an organism whose cells contain a nucleus within a membrane. Eukaryotes vary from single-celled organisms to complex multicellular animals and plants. In fact, most living things are eukaryotes, made up of cells with distinct nuclei and chromosomes that contain their DNA.
Autotroph definition- An organism capable of synthesizing its own food from inorganic substances, using light or chemical energy. Green plants, algae, and certain bacteria are autotrophs.
Heterotroph definition- A heterotroph is an organism that cannot manufacture its own food by carbon fixation and therefore derives its intake of nutrition from other sources of organic carbon, mainly plant or animal matter. In the food chain, heterotrophs are secondary and tertiary consumers.

Answer:
Independent variable: Planting depths of seeds
Dependent variable: plant height
Explanation:
Independent variable in an experiment is the variable that the experimenter changes or manipulates in order to bring about a measurable response. In this experiment involving the planting of radish seeds at varying depths, the DEPTH AT WHICH THE SEEDS ARE PLANTED is the independent variable.
Dependent variable is the variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this experiment, the HEIGHT of the radish plants measured is the dependent variable.
