movement
ameoba constantly changes shape when it encounters an obstacle
how does the amoeba move?
by extending out its pseudopodium
how does a paramecium move?
by using rhythmic cilia beats
how do amoeba and paramecium respond to stimuli
they respond to stimuli such as chemicals, touch or brightness by moving away from the stimuli
respiration of amoeba and paramecium
exchange of oxygen and carbon dioxide gasses occurs throughout the plasma membrane by simple diffusion on the surface of the cell
how do the amoeba and cytoplasm grow
it grows by synthesising new cytoplasms
how does the amoeba move towards food ?
it does so by extending out its pseudopodium to trap food particles by phagocytosis
how does the paramecium eat?
the presences of cilium beat helps transfer food particles to the oral groove
undigested food of paramecium
Discharge through the anus
undigested food of Amoeba
is will be discharged as it moves
how are waste removed?
by diffusion
what will happen when the vocuole expands to its maximum size
contraction will occur and water will be excreted from time to time
what process is it when water is excreted from time to time?
osmoregulation
what will happen when conditions are suitable and there is plenty food
it will reproduce through asexual reproduction that is binary fission through mitosis
what will happen when conditions are not suitable for amoeba
it will form spores that will only germinate when the environment improves
