Biology AQA GCSE Topic 1 Flashcards
The funtion of Cell wall
Strengthens the cell and gives support (make out of cellulose
The funtion of vacuole
Support the cell and keeps it rigid.A permanent vacuole is a fluid-filled sac that stores water
The funtion of chloroplast
Contains chlorophyll for photosynthesis
The funtion of chlorophyll
Green pigment that adsorbs light energy
The funtion of nucleus
Contains genetic information and controls the cell
The funtion of cytoplasm
Where most chemical reactions occur, controlled by enzymes
The funtion of cell membrane
Controls movemnt of substances in and out of the cell
The funtion of mitochondria
Site of respiration,where energy is released
The funtion of ribosomes
Protein synthesis
Funtion of Root hair cell
Absordbing water and minerals
Adaption of Root hair cell
Lots of mitochondria to transfer minerals, increased surface area to absorb more water
Function of nerve cell
Carry electrical impulses around body
Adaption of nerve cell
Lots of dentrites to make connections to other cells
Function of sperm cells
To contain genetic information from male and to fertilise egg
Adaption of sperm cell
Long tail to move and middle section full of mitochondria to transfer enegry for tail.
