Question

1) Which of the following is NOT true about protists?

a) protists are enormously important in global photosynthesis and biogeochemical cycles

b) Protists are a monophyletic group

c) protists include all eukaryotes except plants, animals and fungi

d) Some major clades of protists (e.g. diatoms) are much younger than plants or animals

2) The evolution of the cytoskeleton in eukaryotes allowed for wich new capabilities lacking in prokaryotes? (Multiple Answer)

a) Mitosis and meiosis

b) Phagocytosis

c) Amoeboid motion

d) Horizontal gene transfer through conjugation

3) Which of the following is/ are Haploid in the alternation of generations lifecycle in plants? (Multiple Answer)

a) Sporophyte

b) Gametes

c) Spores

d) Zygote

Answer 1

1.The answer is B because Protists make up a group that is paraphyletic, meaning that they do not make up all of the descendants of their most recent common ancestor.A true taxonomic group is considered monophyletic

2. prokaryotes are unable to perform phagocytosis, that means by which the endosymbiont entered its host is an enigma.

Although eukaryotes and prokaryotes both engage in cell division, they do so in different ways. In particular, eukaryotic cells divide using the processes of mitosis and meiosis

Horizontal gene transfer is known to occur between different species, such as between prokaryotes

So the correct answer is A and D

3.The zygote develops into the diploid sporophyte, which extends from the gametophyte and produces haploid spores through meiosis. But the haploid stage, in which a multicellular haploid gametophyte develops from a spore and produces haploid gametes and generates lifecycle plants

So the correct answer is B and C
