BIO 1500 EXAM 4 STUDY GUIDE 2026/2027 | EXAM REVIEW &
PRACTICE QUESTIONS
Photosynthesis - Correct answer✅✅ the process that converts solar energy into chemical energy
Autotrophs - Correct answer✅✅ sustain themselves without eating anything derived from other
organisms
Photoautotrophs - Correct answer✅✅ Almost all plants. Using the energy of sunlight to make organic
molecules
Heterotrophs - Correct answer✅✅ obtain their organic material from other organisms. The
'consumers' of the biosphere. Almost all depend on photoautorophs for food and O2
General photosynthesis equation - Correct answer✅✅ 6CO2 + 6H20 + light energy = 6CH126O2
photosynthetic cells - Correct answer✅✅ include enzymes and other molecules grouped together in a
membrane. Allows for chemical reactions of photosynthesis to proceed efficiently
Chloroplast are found mainly - Correct answer✅✅ in cells of the mesophyll, the interior of the leaf
Each mesophyll cell - Correct answer✅✅ contains 30-40 chloroplasts
Wavelength - Correct answer✅✅ distance between crests of waves
photons - Correct answer✅✅ light behaves as though it consists of discrete particles
pigments - Correct answer✅✅ substances that absorb visible light
