Photosynthesis

Flashcards about photosynthesis.

Photosynthesis

Green plants or producers that use light energy to make their own food.

Chlorophyll

Green plants contain this pigment to trap light energy.

Starch

The storage form of glucose in plants.

Autotrophs

Organisms that make their own food; plants.

Herbivores

Organisms that eat plants; primary consumers.

Carnivores

Organisms that eat other animals; secondary consumers.

Chemotrophs

Organisms that make their own food from chemicals.

Glucose

A form of chemical potential energy.

Large surface area

Flat shape provides this advantage for leaves.

Sunlight can penetrate

Thinness provides this advantage for leaves.

Epidermis

Transparent layer in leaves.

Vascular bundles

Transports products of photosynthesis in leaves.

Stomata

Allows for gaseous exchange in leaves.

Chlorenchyma

Photosynthetic cells in leaves.

Palisade Chlorenchyma

Densely packed cells for maximum sun exposure.

Spongy parenchyma

Loosely packed cells for increased gaseous exchange.

Petiol

Orients the leaf to maximize exposure.

Magnesium

Functional element of chlorophyll.

Reflected color

The color that is not absorbed by a pigment.

Photosynthesis

CO2 + H2O -> O2 + Sugars

Respiration

Sugars + O2 -> H2O + CO2

Thylakoid

Location of the light phase of photosynthesis.

Photolysis

Splitting of water during the light phase.

Stroma

Location of the dark phase of photosynthesis.

Calvin Cycle

Another name for the dark phase of photosynthesis.

Light dependent

The light phase is this; the dark phase is independent.

Chloroplast

Two membranes are in this organelle; inner membrane is thylakoid.

Granum

Stacked coins found inside the chloroplast.

Stroma

Space surrounding the granum inside the chloroplast.

Chlorophyll molecules

Embedded in the thylakoid membrane.

Respiration

6CO2 + 6H2O -> C6H12O6 + 6O2 + energy

Light intensity

Reactant in photosynthesis and is directly proportional to a max level.

25 degrees Celsius

Optimal temperature for photosynthesis.

CO2

Reactant in photosynthesis and is directly proportional to max level.
