Stem Cells
Undifferentiated cells with the potential to develop into various cell types.
Cell theory
States that all organisms are made of one or more cells, and the cell is the basic unit of life.
Mitochondria
Double membrane-bound organelles responsible for aerobic respiration and energy production.
Chloroplast
Double membrane-bound organelles that conduct photosynthesis in plant cells.
Ribosomes
Cellular structures that synthesize proteins.
Lysosomes
Organelles that contain digestive enzymes to break down waste materials and cellular debris.
Cell compartmentalization
The division of cellular functions into distinct organelles to enhance efficiency and organization.
Cilia and Flagella
Hair-like structures that enable movement in some eukaryotic cells.
Centriole
A structure in animal cells that helps organize microtubules during cell division.
Vesicles
Small membrane-bound sacs that transport materials within the cell and to the cell membrane.
Prokaryotic cells
Cells that do not contain a nucleus or other membrane-bound organelles.
Eukaryotic cells
More complex cells that contain a nucleus and membrane-bound organelles.
