cells Flashcards
difference between prokaryotic and eukaryotic cells
prokaryotic cells don’t have membrane bound organelles e.g. mitochondria, chloroplasts, nucleus
four examples of eukaryotic organisms Kingdom and specific example
animal - rhino,mosquito,shark,human
plants - daffodil, wheat, daisy
fungi - yeast, mucor
protoctists - amoeba, chlorella, plasmodium
what Kingdom of organisms are always unicellular
protoctists, bacteria
difference in cell wall composition between bacteria, fungi, plants and viruses
bacteria - murien
fungi - chitin
plants - cellulose
viruses - NO CELL WALL
carbohydrate storage of plants, animals, bacteria, fungi
plants - starch or sucrose
animals - glycogen
bacteria - glycogen
fungi - glycogen
2 disease caused by viruses
aids caused by hiv
flu caused by the influenza virus
ebola caused by the ebola virus
non pathogenic bacterium and its use
lactobacillus used in yoghurt making
saprotrophic nutrition
digestive enzymes released from thread like hyphae (extra cellular excretion)
products of digestion are reabsorbed
how does TMV effect plants
causes discolouration of leaves by preventing the formation of chlorophyll
effect of TMV on plants
causes discolouration of leaves by preventing formation of chlorophyll
how does bacteria reproduce
binary fission (asexual reproduction)
how do viruses reproduce
rely on a host cell to self replicate
they inject their RNA/DNA into the host cells and becomes integrated in the host genome
which is the only kingdom to have nervous coordination
animals
which bacterium causes pneumonia
a spherical bacterium, pneumococcus
cell wall
strengthens cell, fully permeable
