2.
What are two major differences between prokaryotes and eukaryotes? [2]
- PROKARYOTES HAVE NO MEMBRANE BOUND NUCLEUS OR OTHER MEMBRANE BOUND ORGANELLES AND
EUKARYOTES DO
- PROKARYOTES BELONG TO THE DOMAINS ARCHAEA AND BACTERIA WHILE ALL OTHER ORGANISMS BELONG
TO THE DOMAIN EUKARYOTA
- EUKARYOTES ARE LARGER CELLS THAN PROKARYOTES AND USUALLY MULTICELLULAR
- PROKARYOTES HAVE A SMALL CIRCULAR CHROMOSOME AND EUKARYOTES HAVE SEVERAL SEPARATE
CHROMOSOMES
3.a)
What are the two parts of a scientific name? [1]
- GENUS AND SPECIES
b)
What is an important advantage of a scientific name over a common name? [1]
- COMMON NAMES ARE NOT PRECISE AND SCIENTIFIC NAMES ARE VERY SPECIFIC
Version 2
4.
Name2 different ways bacteria reproduce and specify if the method is sexual or asexual. [2]
ASEXUAL - BINARY FISSION – ORGANISM COPIES CIRCULAR DNA AND DIVIDES IN HALF
SEXUAL – CONJUGATION – DNA TRANSFERRED BETWEEN BACTERIA BY A PILI CREATING BACTERIA WITH NEW
DNA COMBINATIONS
SPORES – NOT EXACTLY A FORM OF REPRODUCTION BUT A FORM OF PROTECTING AN ORGANISM FROM
DANGEROUS ENVIRONMENTAL CONDITIONS BUT COULD BE CONSIDERED ASEXUAL IF MENTIONED
5.a)
b)
Explain extracellular digestion. [1]
the organism excretes digestive enzymes to the exterior where the food is
the enzymes break down the food
the organism absorbs the food
Name a kingdom and an organism in that kingdom that obtains nutrients by extracellular digestion. [1]
Fungi – mushrooms
Animalia - Cnidaria
6.
Choose only one of the following comparisons. [4]
compare archaea and bacteria OR compare protists and fungi OR compare protists and animals
A comparison question must state similarities and differences. Compare the same features.
A) archaea and bacteria
Similarities
- they are both prokaryotes
- both are unicellular organisms
- they are both small cells although archaea are smaller than bacteria
- neither has a membrane bound nucleus or other membrane bound organelles
Differences
- archaea are usually anaerobic while bacteria can be either aerobic or anaerobic
- archaea only reproduce asexually while bacteria can reproduce both sexually and asexually
- bacteria have a wider range of nutrition while archaea are usually only heterotrophs
B) protists and fungi
Similarities
- the fungi-like protists are heterotrophs like fungi and eat dead material
- both are eukaryotes
- both reproduce with spores that can be sexually or asexually formed
Differences
- protists are usually unicellular while fungi are multicellular
- fungi usually get nutrition by extra-cellular digestion while protists can be hetertrophs or autotrophs
C) protists and animals
Similarities
- both are eukaryotes
- lack cell walls
- the animal like protists and animals are both heterotrophic
- animals are motile and so are most animal-like protists
Differences
- protists are usually unicellular and animals are multi-cellular
- some protists are autotrophs but not animals
- animals are motile but not all protists are motile
