What feature of living things do the terms unicellular and multicellular describe

a) how they are organized

Explanation:

a) how they are organized

b) how they reproduce

c) how they remain temperature

d) how they produce macromolecules

Organization of the body of living organisms depends on the number of cells they are made of.

Living organisms that are made up of single cell are simple and are generally referred to as unicellular. Example include Euglena, Clamydomonas etc.

Living organisms that are made up of more than one cells are referred to as multicellular. Multicellular organisms complexity varies depending on the number of cells with the most complex living organism (human) containing trillions of cells.

The correct option here is a.

The term unicellular and multicellular describe how living things are organized.

Explanation:

The number of cells in living things determine how the body organization will be.

Living things are made up of cells in which there are two types of living cells. We have the unicellular and multicellular cells.

The unicellular are made up of one cell (single cell) the unicellular organisms are simple cells which make their functions simple while the multicellular organisms are made up of two or more organisms and their functions are special unlike the unicellular which the functions are simple
