UMaine BIO 200 Exam #1 Questions
and Answers
Eukaryotic vs. prokaryotic cells - ANSWER-eukaryotic cells have a membrane-
enclosed nucleus where prokaryotes don't but have free flowing organelles
Bacteria and archaea consist of - ANSWER-prokaryotic cells
Chemotrophs - ANSWER-obtain energy from chemical compounds
Soropollenin - ANSWER-produced by Charles which surrounds the zygote and
protects it from desiccation
Key traits that separate all land plants from Charles - ANSWER-alternation of
generations, walled spores produced in sporangia, and apical meristems
Seed-bearing plants are divided into two groups - ANSWER-gymnosperms and
angiosperms
Gymnosperms - ANSWER-have "naked" seeds/ not enclosed with sporophyte tissue
Angiosperms - ANSWER-enclosed seeds/ 90% of all known plant species
Reduced gametophytes and dominant sporophytes - ANSWER-ferns, seedless
vascular plants, and seed plants
Dominant gametophytes and reduced sporophytes - ANSWER-Moses and
nonvascular plants
Similarities between fungi and animals - ANSWER-both are without chlorophyl, not
self synthesizers, and have similar organelles
Fungi characteristics - ANSWER-heterotrophs(absorb nutrients), have several
different types of cells, cell wall containing chitin, and heterokaryon stage
Fungi are important to an ecosystem because - ANSWER-they are decomposers,
parasites, and mutualists
All nonvascular embryophytes are - ANSWER-bryophytes(do not have roots)
Tracheids - ANSWER-trait in land plants that allow them to grow in height
Sori - ANSWER-found on the underside of the fern leaves and contain sporangia
