Goals:

-5: Use a model to illustrate how photosynthesis transforms light energy into stored chemical

energy.

-7: Use a model to illustrate that cellular respiration is a chemical process whereby the bonds of

food molecules and oxygen molecules are broken and bonds in new compounds are formed resulting

in a net transfer of energy.

-3: Construct and revise an explanation based on evidence for the cycling of matter and flow of

energy in aerobic and anaerobic conditions.

Vocab:

Aerobic respiration: A cellular process that requires oxygen to produce energy from organic

compounds.

Anaerobic respiration: A cellular process that does NOT require oxygen to produce energy

from organic compounds.

Electron transport chain: Uses high energy electrons to convert ADP to ATP.

Krebs (Citric Acid Cycle: Uses pyruvic acid from glycolysis to generate energy during the

process of aerobic respiration

Cellular respiration: Process that releases energy by breaking down glucose and other food

molecules in the presence of oxygen to produce ATP

Light dependent: The first stage of photosynthesis occurring in the thylakoid membranes that

captures energy from light and drives the production of ATP

Light independent (Calvin): A chemical reaction that convert carbon dioxide and other

compounds into glucose. These reactions occur in the stroma, the fluid-filled area of a

chloroplast outside of the thylakoid membranes

Glycolysis: First stage of cellular respiration that break downs glucose releasing energy and

pyruvic acid

Photosynthesis: Process by which plants use light energy to convert water and carbon

dioxide into oxygen and sugar

ATP: Energy molecule that all cells use to store and release energy

Chlorophyll: A pigment in the chloroplast of plants that captures light energy.

Stroma: Liquid outside the thylakoid membranes in chloroplast. Location of the Calvin Cycle

Thylakoid: Stacks of sac-like membranes in chloroplast. Location of light dependent reaction

Fermentation: Process by which cells release energy in the absence of oxygen. Two types:

Lactic acid and alcoholic

Roots: Underground organ in plants that absorbs water and minerals

Stems: Supporting structure that connects roots and leaves and carries water and nutrients

between them

Leaves: Portion of the plant that is responsible for photosynthesis

Flowers: Seed bearing structure of the plant

Dermal Tissue: Outer tissue of the plant, made of epidermal cells

Ground Tissue: Middle tissue, important for photosynthesis, storage and support

Name:__________________________________

Vascular Tissue: Plant tissue that conducts water and nutrients throughout the plant

Xylem: Vascular tissue that carries water upward from roots

Phloem: Vascular tissue that carries nutrients and carbohydrates from photosynthesis
