AQA GCSE Biology B1 Study Guide
Exam And Correct Answers .
What are cells? - Answer The building blocks of organisms
Define eukaryotic cell - Answer Cells that have a true nucleus
Define prokaryotic cell - Answer Cells that do not have a true nucleus
What is in an animal cell? - Answer Nucleus, cytoplasm, cell membrane, mitochondria, ribosomes
What is in a plant cell? - Answer Same as animal plus: vacuole, chloroplasts, chlorophyll, cell wall
What is in a yeast cell? - Answer Same as animal plus: temporary vacuole, cell wall
What is in a bacterial cell? - Answer Cytoplasm, cell membrane, cell wall, ribosomes, chromosomes,
plasmid, capsule, flagellum
Function of nucleus - Answer The control centre of the cell, contains DNA
Function of cytoplasm - Answer Where chemical reactions take place
Function of cell membrane - Answer Controls the flow of substances into and out of the cell
Function of mitochondria - Answer Releases energy into the cell in respiration
Function of ribosomes - Answer Where protein synthesis takes place
Function of vacuole - Answer Keeps the cell turgid (filled with plant sap)
, Function of chlorophyll - Answer Absorbed light energy in photosynthesis
Function of cell wall - Answer Provides structure for the cell, made of cellulose
Function of chromosomes - Answer Carries genetic information
Function of plasmid - Answer Carries genetic information
Function of capsule - Answer Protects against phagocytosis
Function of flagellum - Answer Helps the cell move
Adaptations of muscle cells - Answer 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 - Answer 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 - Answer Increase surface area for water to move up the cell
Have mitochondria that transfer energy needed for transport of mineral ions into the cell
Have a large permanent vacuole that speeds up the movement of water by osmosis
Adaptations of sperm cells - Answer Long tail to whip to propel the sperm forward
Middle section has lots of mitochondria which transfer energy to the tail
Large nucleus for the DNA that needs to be passed on
