Studied by 0 peopleEukaryotic cell
A type of cell with a nucleus and membrane-bound organelles.
Ultrastructure
The detailed structure of cellular components like ribosomes, cytoskeleton, mitochondria, etc.
Prokaryotic cell
A type of cell without a nucleus or membrane-bound organelles.
Endosymbiotic theory
Theory proposing that mitochondria and chloroplasts were once free-living prokaryotes engulfed by ancestral eukaryotic cells.
Cytoskeleton
A network of protein fibers (microtubules, microfilaments, intermediate fibers) that provides structural support and facilitates cell movement.
Mitochondrion
Organelle responsible for aerobic respiration and ATP production in both plant and animal cells.
Chloroplast
Organelle found in plant cells responsible for photosynthesis, containing chlorophyll and thylakoid membranes.
Organelle
Subcellular structure with specialized functions, such as the nucleus, Golgi apparatus, lysosomes, etc.
Protein production and trafficking
The process involving different organelles and molecules in synthesizing and transporting proteins within a cell.
Light Microscopy
Technique using visible light to produce magnified images of cellular components.
Transmission Electron Microscopy (TEM)
Technique using electrons to visualize the internal structure of cells at high resolution.
Scanning Electron Microscopy (SEM)
Technique using electrons to create detailed 3D images of cell surfaces.
Cellulose
A structural carbohydrate found in plants.
Chitin
A structural polysaccharide found in fungi.
Slime capsule
A layer around the cell, outside the cell wall.
Flagellum
A whip-like structure for cell movement, with a different structure in prokaryotes compared to eukaryotes.
9+2 arrangement of microtubules
A specific arrangement of microtubules in flagella.
Cell surface membrane
Present in prokaryotes.
Reproduction
Can occur through binary fission and can be asexual or sexual.
Cytoskeleton
Present in prokaryotes, providing structural support.
Pili
Present in some prokaryotes but absent in others.
