Bio 93 Mock Exam Review (Test Questions and 100% Correct Answers) A biologist ground up some plant leaf cells and then centrifuged the mixture to fractionate the organelles. Organelles in one of the heavier fractions could produce ATP in the light, while organelles in the lighter fraction could produce ATP in the dark. The heavier and lighter fractions are most likely to contain, respectively, A) mitochondria and chloroplasts. B) chloroplasts and peroxisomes. C) peroxisomes an...

• Cell: The basic structural and functional unit of every organism. • Types of Cells o Prokaryotic [Archaea & Bacteria] o Eukaryotic [Animals, Plants, Fungi] • All cells have o Plasma Membrane o Cytoplasm o Chromosomes [contain genes] – Made of Chromatin o Ribosomes [make proteins] – Made of RRNA & Protein • Prokaryotic Cells [Smaller] o No nucleus o DNA in nucleoid o No membrane bound organelles • Eukaryotic Cells [Larger] o DNA in a nucleus bounded by a double membr...

 Mitochondria and chloroplasts- produce cellular energy; cellular respiration and photosynthesis  Cellular membrane- protect, communicate, and passage of substances into and out of the cell • Bilayer of phospholipids with proteins, cholesterol, and glycoproteins o Cellular respiration  ATP is energy currency of cell  NADH is the reducing agent and is a vehicle of stored energy; precursor to produce greater amounts of ATP in final steps of respiration o Glycolysis- convers...

Obligate halophiles - High osmotic pressure aka lots of salt like the great salt lake Facultative halophiles - Type that causes acne can be in salty also known as osmolaric but not nessesary Neutrophiles - Most bacteria Protozoa and pathogens like neutral ph rang 6.5-7.5 Acidophiles - Really acidic as low as 0 pH Alkalineophiles - Grow best in basic range up to 11.5 ex cholera Thermophiles - Higher temperatures above 45C ex hot springs Hyperthermophiles - Hottest 80C and above Mesophiles...

Alternation of generations - Cycle has BOTH multicellular haploid & multicellular diploid forms Are the most visible life stages of the land plant groups sporophytes (2n) or gametophytes (n)? - All are sporophyte except nonvascular is gametophyte Changing-environment hypothesis - offspring that are genetic clones of their parents are unlikely to thrive if the environment changes Crossing over - homologous chromosomes exchange genetic information Diploid dominant life cycle - Similar to ani...

what is the function of the plasma membrane? - ️️1) separates cell from external environment 2) regulates transport of molecules Plasma membrane characteristics - ️️Marks boundary between outside and inside of a cell • Regulates passage in and out of a cell • Phospholipid bilayer with embedded proteins o Polar heads (hydrophilic) of phospholipids face into watery medium o Nonpolar tails (hydrophobic) face each other Hydrophobic vs. Hydrophilic - ️️The polar heads are hyd...
