This organelle is the "control center" of the cell, storing genetic material (DNA) and directing cellular activities.
Nucleus
Found in plant cells, fungi, and bacteria, this rigid outer layer provides structural support and protection.
Cell Wall
Skeletal muscle cells require massive amounts of ATP energy to sustain contractions. Which organelle is found in unusually high abundance in muscle tissue?
Mitochondria
These small, non-membrane-bound structures are responsible for synthesizing proteins.
Ribosomes
Out of the Nucleus, Mitochondria, Ribosomes, and Endoplasmic Reticulum, this is the only structure found in BOTH prokaryotic and eukaryotic cells.
Ribosomes
A cell starts accumulating damaged organelles and cellular waste in its cytoplasm because it can no longer digest them. Which organelle is malfunctioning?
Lysosome
Known as the "powerhouse of the cell," this organelle performs cellular respiration to produce usable ATP energy from glucose.
Mitochondria
This organelle converts solar energy into chemical energy (glucose) during photosynthesis in plant cells.
Chloroplast
Finding a thriving single-celled microbe in a boiling hot spring supports Cell Theory because it proves life doesn't need a complex body to exist—just this basic unit of structure.
This membrane network is studded with ribosomes and helps fold and modify newly synthesized proteins.
(Rough) Endoplasmic Reticulum
If a plant cell is missing a central vacuole, it would be unable to perform this crucial survival function.
Storage of water and materials
Before 1850, people believed maggots magically appeared from rotten meat (spontaneous generation). State the key rule of Cell Theory that debunked this idea forever.
Cells come from cells
This organelle modifies, sorts, and packages proteins for secretion or transport to other organelles
Golgi Apparatus or Bodies
Name the two specific organelles that are found in plant cells, but are NOT found in animal cells.
Cell Wall and Chloroplast
Someone tells you, "Every cell on Earth has a nucleus." Point out the flaw in their claim by naming the major type of organisms that proves them wrong.
