specialised cell
red blood cell function and adaptation
function : carry oxygen around the body
adaptation: bi-concave shape to maximse surface area for diffusion of oxygen ; contain haemoglobin - a molecule that reversibly binds to oxygen
Root hair cell function and adaptation
Function: let plants absorb minerals from soil
Adaptation: Lots of mitochondria for energy for active transport ; Large surface area from long projections to increase the rate of absorption
Sperm cell function and adaptation
function: to fertialise egg cells
adaptation: Acrosome at its head to digest a pathway tp the egg ; contains nucleus in the head that'll fertialise the agg ; packed with mitochondria to provide energy for the cell to swim ; a tail to help travelling to the egg
ciliated epithelium function and adaptation
function : move substances in one direction
adaptation: have lots of mitpchondria for energy to move substances ; covered with cilia ( tiny hair )
palisade ( leaf) cell function and adaptation
function: help to absorb sunlight for photosynthesis
adaptation: contain chloroplast for photosynthesis ; collum shaped to arrange mitochondria closely together
