EVERYDAY SCIENCE

Detailed explanation-1: -Leaf shape is inherently quantitative, likely representing the complex interplay of many different genes and gene regulatory networks.

Detailed explanation-2: -Qualitative data can be a record of differences in qualities, such as color change of a solution or the vitality of a plant over time. These kinds of data may be recorded in a table. Or qualitative data can be pictorial, such as a cell seen through a microscope or the petal structure of a flower.

Detailed explanation-3: -Growth is an irreversible increase in plant size accompanied by a quantitative change in biomass (weight). Development is more subtle and implies an additional qualitative change in plant form or function such as a phase change from vegetative to reproductive growth.

Detailed explanation-4: -Quantitative features such as variability, noise, robustness, delays or feedback loops are included to account for the inner dynamics of plants and their interactions with the environment.
