AQA GCSE Biology B1
What are cells? - ✔✔✔The building blocks of organisms
Define eukaryotic cell - ✔✔✔Cells that have a true nucleus
Define prokaryotic cell - ✔✔✔Cells that do not have a true nucleus
What is in an animal cell? - ✔✔✔Nucleus, cytoplasm, cell membrane, mitochondria, ribosomes
What is in a plant cell? - ✔✔✔Same as animal plus: vacuole, chloroplasts, chlorophyll, cell wall
What is in a yeast cell? - ✔✔✔Same as animal plus: temporary vacuole, cell wall
What is in a bacterial cell? - ✔✔✔Cytoplasm, cell membrane, cell wall, ribosomes, chromosomes,
plasmid, capsule, flagellum
Function of nucleus - ✔✔✔The control centre of the cell, contains DNA
Function of cytoplasm - ✔✔✔Where chemical reactions take place
Function of cell membrane - ✔✔✔Controls the flow of substances into and out of the cell
Function of mitochondria - ✔✔✔Releases energy into the cell in respiration
, Function of ribosomes - ✔✔✔Where protein synthesis takes place
Function of vacuole - ✔✔✔Keeps the cell turgid (filled with plant sap)
Function of chlorophyll - ✔✔✔Absorbed light energy in photosynthesis
Function of cell wall - ✔✔✔Provides structure for the cell, made of cellulose
Function of chromosomes - ✔✔✔Carries genetic information
Function of plasmid - ✔✔✔Carries genetic information
Function of capsule - ✔✔✔Protects against phagocytosis
Function of flagellum - ✔✔✔Helps the cell move
Adaptations of muscle cells - ✔✔✔Contain proteins that slide over each other making fibres contract
Contain mitochondria to transfer energy
Store glycogen used in cellular respiration
Adaptations of nerve cells - ✔✔✔Lots of dendrites to make connections to other nerve cells
The axon carries the nerve impulses from one place to another and are often very long
Synapses pass impulses to another cell or between a nerve and the muscle
Adaptation of root hair cells - ✔✔✔Increase surface area for water to move up the cell
