For instance, it is possible that prokaryotic cells directly exchange DNA with other Root system prokaryotic cells, through physical contact, in a process known as: a) Transformation b) Transduction c) Mutation d) Conjugation e) Binary fission 6 - In some eukaryotic cells, some organelles are surrounded by more than two membranes. Together with the presence of a nucleoid, this is evidence in support of a) Evolution from the mitochondria b) Fusion of plastids c) Origin of plastids from Archaea d) Secondary endosymbiosis 7 - In land plants, life cycle with alternation of generations, consists of multicellular haploid forms that alternate with: a) unicellular haploid forms b) unicellular diploid forms c) multicellular haploid forms d) multicellular diploid forms e) None of the above.

Answer 1

Answer for question number 7 : The correct option is C ( multicellular haploid forms)

Explanation : A term primarily used to describe the life cycle of plants during which a multicellular diploid sporophyte alternates with multicellular haploid gametophyte. The sporophyte produces spores by meiosis which grows and germinates into a gametophyte at maturity gametophyte produces gametes by mitosis.

Example : life cycle of bryophytes is characterised by regular alternation of morphologically distinct phases
