The Cell Flashcards
The cytoplasm is
A jelly like substance that contains fibres cytosol and organelles
Cytosol is…
An intra cellular fluid and is where chemical reactions take place
Organelles are?
Specialised structures that have characteristic shapes and have specific functions
The cytoskeleton is
A network of protein filaments that provides support and forms centrosomes, cilia flagella and microvilli
Centrosomes are
2 centrioles that direct the movement of dna during division
Cilia is
Short hair like projections that move dust and dirt so we can swallow it
Flagella are
Longer hairs like a tail that move so the cell can move
Ribosomes are
Small structures that join amino acids together to make proteins
Endoplasmic riticulum
A network of membranes in the shape of flattened sacs or tubules
Rough ER
Connected to the nuclear envelopes and studded with ribosomes synthesis proteins
Smooth ER
Network of membrane tubules not containing ribosomes. Synthesyses lipids
The Golgi complex is
3-20 membrane sacs which modifies, sorts and packages proteins for transport
Lysosomes are
Vesicles pinched off the Golgi complex that contain digestive enzymes to digest unwanted organelles, other molecules like mitochondria, particles/cells the cell has ingested
Mitichondria is
Power house of cell, generated energy, more common in physiology cells.
The nucleus is
A spherical or oval structure that contains DNA
