G9 Biology Vocabulary Matchup - Cell structure and function - Biological molecules - Levels of organization - Energy and nutrient flows through ecosystems

Sep 28, 2026

G9 Biology Vocabulary Matchup summarizes core biology terms across multiple MYP Science units, focusing on cell structure, biological molecules, and levels of organization. It defines the cell theory and key organelles (nucleus, chromosomes, mitochondria, Golgi complex, ribosomes, smooth and rough ER), then contrasts plant and animal cell features. The resource extends to ecosystem organization (organisms, populations, communities, ecosystems, biomes) and outlines energy and nutrient flow concepts including open systems, transfer, transformation, and thermodynamics with trophic-level efficiency.

FAQs

What is the cell theory and how do cells relate to one another?

The cell theory states that the cell is the smallest unit of life, all living things are made of cells, and all cells come from pre-existing cells.

How do mitochondria support cellular life?

Mitochondria are organelles where cellular respiration takes place, providing energy to the cell.

What do open systems mean in ecosystem energy and matter flow?

Open systems are ecosystems that have inputs and outputs of energy and matter, with energy and matter moving through and cycling within the system.
