What are the fundamental building blocks of plants?

The fundamental building blocks of plants are cells. Cells are the smallest units of life that can carry out all the functions necessary for an organism. In plants, cells have specific structures that allow them to perform various roles, such as photosynthesis, nutrient transport, and support. They form the various tissues and organs that make up the plant.

While atoms are the basic units of matter that make up cells, they are not specific to plants and are therefore more general in nature. Tissues are composed of groups of cells working together to perform specific functions, but they are not the most basic unit. Similarly, organs are made up of multiple tissues and serve complex functions within the plant. Thus, cells are accurately identified as the fundamental building blocks necessary for the structure and function of plants.
