Cell Bio Chap 6 - Photosynthesis

Based on the cycle of photosynthesis and cell respiration, the ultimate source of energy for all living things is _______

• the sun
• mitochondria
• ATP
• chloroplast

Heterotrophs are organisms that can

• create their own energy from the sun
• consume other organisms for energy
• create their own energy from inorganic molecules
• carry out photosynthesis

Autotrophs are organisms that can

• survive in dark spaces
• consume other organisms for energy
• produce food from inorganic molecules and sunlight
• survive without energy

process whereby plants capture energy and make complex molecules is

• cell respiration
• homeostasis
• translation
• photosynthesis

stacks of disk shapes that contain chlorophyll within the chloroplasts are

• thylakoids
• mitochondria
• stroma
• ribosomes

The light-dependent reaction takes place in the

• stroma
• thylakoids
• mitochondria
• cytoplasm

The organelle where photosynthesis occurs is the

• mitochondria
• ribosomes
• Golgi apparatus
• chloroplast

All carbon molecules used by organisms can be traced back to

• oxygen in the atmosphere
• carbon dioxide in the atmosphere
• water
• ATP

Chlorophyll is green because it reflects green wavelengths of light

• true
• false

The role of chlorophyll is to

• absorb light energy
• split water molecules
• create ATP
• absorb carbon dioxide
