Unit 3 Vocabulary: Cells & Organelles - Biology 1

tiny, microscopic, living things that build all living things.

Bacteria, amoebas, living organisms consisting of only 1 cell

Larger organisms, with cell differentiation (different cells carry out different tasks).

Structures within a cell that carry out specific functions (purposes).

Simple cell, with an outer cell wall but no nucleus or organelles.

Complex cells, made of differentiated organelles and a nucleus

Eukaryotic organelle containing DNA & chromosomes

Surrounds all cells and selectively controls what enters and exits the cell.

Thick liquid filling the living cell, allowing the organelles to float

Almost living, but not, as they need a host (a cell to invade) in order to reproduce. They are organic, and have genes, yet are parasites.
