BIOLOGY 210 - UNIT 2 EXAM REVIEW
QUESTIONS WITH VERIFIED ANSWERS
2 sources of organic molecules - correct answer- -autotrophs
-heterotrophs
3 algal groups most similar to land plants: - correct answer- -
Zygenematophycease (conjugating algae)
-Coleochaetales (coleochaetales)
-Charophyceae (Stoneworts)
3 sources of energy for ATP production - correct answer- -
light (photo-)
-organic molecules, (chemoorgano-)
-inorganic molecules (chemolitho-)
3 Steps of information processing in plants - correct answer-
-Sensory cells receive external signal and convert it to a mobile
intracellular signal
-Intracellular signal travels from cell-cell to other areas of the
plant
,-Target cells receive signal and change activity to produce
specific response
3 ways infectious diseases are spread - correct answer- 1.
person-person
2. insect or animal bites
3. ingestion or exposure to contaminated food,water,or
surrounding environment
4 Modes of Diversification of Bacteria and Archaea - correct
answer- -genetic variation through gene transfer
-morphological diversity
-metabolic diversity
-ecological diversity
Adaptations for living and reproducing on land in land plants: -
correct answer- -Cuticle and sporopollenin (waxy coatings)
-Vascular tissue (structure and water transport)
All land plants undergo alternation of generations, in which
individuals have, - correct answer- A multicellular haploid
phase called the gametophyte
, A multicellular diploid phase known as the sporophyte
All organism must: - correct answer- -acquire chemical
energy (to make ATP)
-obtain carbon compounds (building blocks for cellular
components)
Alveolata - correct answer- Cells have sac-like structures
called alveoli that form a continuous layer just under the plasma
membrane. Thought to provide support
Amoeboza - correct answer- Cells lack cell walls. When
portions extend outward to move the cell, they form large lobes
Angiosperms abundant - correct answer- 145 mya
Diversification of flowering plants
Antiobiotics - correct answer- -molecules that kill or stop
bacterial growth
-naturally produced by some bacteria and fungi
-discovered in '28 by Fleming
