Detailed explanation-1: -Living things are highly organized following a hierarchy that includes atoms, molecules, organelles, cells, tissues, organs, and organ systems. Organisms, in turn, are grouped as populations, communities, ecosystems, and the biosphere.

Detailed explanation-2: -Organisms are individual living entities. For example, each tree in a forest is an organism.

Detailed explanation-3: -Plant organs group together to form the two main organ systems of plants: the root system and the shoot system. The root system is typically underground and includes the root and associated fibers that branch off the main root. This system functions to anchor the plant and absorb water and nutrients from the soil.

Detailed explanation-4: -Levels of organization for structure and function of a multicellular organism include cells, tissues, organs, and organ systems. 1.1f Many plants have roots, stems, leaves, and reproductive structures. These organized groups of tissues are responsible for a plant’s life activities.

Detailed explanation-5: -The most complex level of organization is the organismal level, where all eleven organ systems function in the human organism, the whole living person.
