Study Guide Plant Processes and Plants Test
Photosynthesis
 Photosynthesis is a process where plant cells use the energy from sunlight to make
food (glucose, C6H12O6) from carbon dioxide (CO2) and water (H2O).
 Photosynthesis takes place in chloroplasts.
o Chlorophyll is a green pigment, found in chloroplasts, that absorbs light energy for
photosynthesis.
o Chlorophyll gives plants their green color.
 An organism with chloroplasts is called a producer.
Photosynthesis can be summarized by the following equation:
yields
6 CO2 +
carbon dioxide
6 H2O + light energy
water
sunlight
C6H12O6 +
glucose
6 O2
oxygen
 Nearly all of the energy that fuels life comes from the sun.
Stomata: openings in the epidermis and cuticle of the leaf that allow carbon dioxide to enter
the leaf and water and oxygen to exit it.
Transpiration: the loss of water from plant leaves through openings called stomata.
Cellular Respiration
 Cellular respiration is the process of producing ATP (energy) in the cell from oxygen and
glucose; releases carbon dioxide and water.
 Cellular respiration takes place in a cell's mitochondria.
 The three products of cellular respiration are carbon dioxide, water and ATP.
The equation for cellular respiration is:
C6H12O6 +
glucose
6 O2
yields
6 CO2 +
oxygen
carbon dioxide
6 H2O + ATP
water
energy
How are cellular respiration and photosynthesis related?
 Photosynthesis and cellular respiration are dependent upon one another because
photosynthesis requires the carbon dioxide produced during cellular respiration, which
requires the oxygen and sugar produced during photosynthesis.
Tropism
Phototropism is a change in the growth of a plant in response to light.

Plant Vocabulary to Know:
Nonvascular plants- do not have tissues or “plumbing to deliver materials to the plant
Vascular plants- have tissues or “plumbing” that delivers materials throughout the plant
Xylem- transports water and minerals up vascular plants
Phloem- transports sugar molecules down vascular plants
Gymnosperms- non-flowering plants
Examples: conifers, pines
Angiosperms-flowering and fruiting plants
Examples: apple tree, dandelion
