About Biology

Biology spans the smallest working parts of life and the largest patterns among them. On this grid you will find the machinery inside a cell: ribosomes assembling proteins, chloroplasts capturing light for photosynthesis, chromosomes carrying DNA, and mitosis dividing one cell into two identical copies. Other clues step outward to whole organisms and where they live, from single-celled amoebas and fungi to neurons, vertebrae, predators, and the habitats that shape which species survive there.

Reach for this sheet in a middle school or high school life science class when students need to review cell structure and ecology vocabulary before a unit test.
