Study Guide Answer Key 1) a. nutrients enter/leave the cell b. digestive area c. control center and contains genetic material d. energy producing area; powerhouse; has ATP e. protein synthesis f. gives strength to plant g. where photosynthesis takes place h. jelly like substance containing organelles i stores proteins j. packages proteins 2) 6CO2 + 6H2O (+ light energy) C6H12O6 + 6O2 2a. oxygen and glucose 2b. photosynthesis 2c.green pigment; photosynthesis; stroma - fluid filled space, light reactions thylakoid - stack flattened membranes, dark reactions 2d. light dependent; light independent, dark, Calvin cycle 3) C6H12O6 + 6O2 6CO2 + 6H2O + energy 3a Oxygen and glucose; CO2 and water 3b glycolysis; plants and animals 3c mitochondria 3d fermentation 4)ATP 5) Oxygen and glucose are produced during photosynthesis; O2 and glucose are used during respiration. 6) Large particles ; active (requires energy); takes in large particles

7) does NOT use energy; diffusion, osmosis and facilitated diffusion 8) movement 9) *Hypertonic, high solute - If cell is placed in this soln. it will expel water (shrink) *Hypotonic, low solute - If cell is placed in this soln. it will absorb water (swell) *Isotonic, equal; a cell in an isotonic soln does not change 10) starches; monosaccharides 11) A) Carbohydrates, monosaccharides (sugars), source of energy B) Lipids, glycerol & fatty acids, long term energy storage C)Proteins, amino acids, growth and repair


D) Nucleic acids, nucleotide, contains genetic info 12) Has a nucleus and organelles; Ex: protist, animal and plant cells 13) Has a plasma membrane, cytoplasm, and DNA (Nucleic Acids). They lack a nucleus and nuclear envelope. Ex: bacteria. 14) chloroplasts and cells walls 15) growing; G1: growing S: DNA replication (copy) G2: Checks itself P - chromosomes replicate M – chromo. line up at the middle A - sister chromatids move away to poles T - 2 nuclei forms C - cytoplasm divides into 2 identical cells 16) 2 17) asexual; 2 18)

19) skin 20) gametes 21) prophase I 22) 4 23) 43 24) genetically different
