process in the _____________ (organelle) which can be found in a ______ of any plant.
during photosynthesis, ________ energy is converted into ________ energy using the
________ transported on the electron carrier called ________.

1. cells trap energy from sunlight with the green pigment __________ found in the

individual discs called __________ within the chloroplast.

1. guard cells control the________ in the leaf which allows for ____ ______

to enter the plant cell. __________ is absorbed from the roots to help the process. these
reactants are used to form the energy - rich molecule __________.

1. __________ is released out of the stomata as a waste product.

aerobic cellular respiration: adp, atp, electron transport chain, energy, glucose, krebs/citric acid, mitochondria,
nadh, phosphate group, pyruvate, waste, water
in order to actually use energy stored in glucose, eukaryotic cells perform cell respiration in the cytoplasm
and the _______________ (organelle).

1. cells break down ________ in glycolysis to make two ________.
2. then, that pyruvate is turned into acetyl coa to start the __________ cycle. during this step,

carbon dioxide is released as ________. electron carriers like fadh2 and ________ collect
electrons to use in the ________ ______ ________.

1. as a result, atp is made as a source of ________ for work. ________ is a byproduct of etc.
2. when cells need energy to do work, a bond in ________ is broken and becomes ________. atp

loses a ________ ________ during this process.
anaerobic cellular respiration: atp, aerobic, alcohol, anaerobic, fermentation, lactic acid, oxygen

1. there are 2 kinds of cellular respiration: _____________ (requiring ________) and

_____________ (not requiring oxygen). aerobic respiration produces more ______ than
anaerobic respiration.

1. __________ is an example of anaerobic respiration. the 2 main types of fermentation

are: ______ ____ & ________.

Explanation:

Photosynthesis occurs in chloroplasts (found in leaf cells). Light energy is converted to chemical energy. Chlorophyll in thylakoids traps light. Stomata regulate gas exchange (CO₂ in, O₂ out). Water is absorbed. Reactants (CO₂ and H₂O) make glucose. Aerobic respiration in mitochondria breaks glucose to pyruvate (glycolysis), then Kreb's cycle (CO₂ as waste). NADH carries electrons to electron transport chain. ATP is energy source. When ATP breaks, it becomes ADP (loses phosphate group). Cellular respiration: aerobic (needs O₂) makes more ATP than anaerobic. Fermentation (anaerobic) examples: lactic acid and alcohol fermentation.

Answer:

Photosynthesis: chloroplast, leaf, light, chemical, NADPH; 1. chlorophyll, thylakoids; 2. stomata, carbon dioxide, water, glucose; 3. oxygen. Aerobic Cellular Respiration: mitochondria; 1. glucose, pyruvate; 2. Kreb’s/Citric acid, waste, NADH, electron transport chain; 3. energy, water; 4. ATP, ADP, phosphate group. Anaerobic Cellular Respiration: 5. aerobic, oxygen, anaerobic, ATP; 6. Fermentation, lactic acid, alcohol.
