An organism that is able to form nutritional organic substances from simple inorganic substances like CO2.
Most common type of plant, best at photosynthesis in cool, wet climates.
Plant that performs Photosynthesis in hot, dry climates by closing stomata during the day to preserve water, and collecting CO2 during the night. Light dependent reaction occurs in Mesophyll cell which is also where the CO2 is stored in a four carbon compound. Calvin Cycle occurs in Bundle Sheath during the night.
Not Unlike C4 plants except the whole reaction happens in the Bundle sheath
Aids in CAM and C4 plant's Photosynthesis. Near leaf's vain
Aids in C4 plant photosynthesis conducts light reactions and stores CO2. spongey layer in leaf
An organism that obtains organic food molecules by eating other organisms or substances derived from them; a consumer or decomposer in a food chain.
Start off with a molecule ribulose biphospate made of 5 carbon atoms
A molecule of carbon dioxide is added to this to make a 6 carbon atom
In a series of reactions, the 6 carbon molecule is broken in half to form two 3 carbon molecules called glyceraldehyde-3-phosphate(G3P)
One of the G3P molecule is used to make glucose and other carbohydrates while the other G3P molecule is used to regenerate the original ribulose biphosphate.
The cycle repeats again.
Light dependent cycle
H2O and Light Enters. Products= O2 NADPH
ATP IS THE PRODUCT
The distance between crests of adjacent waves, such as those of the electromagnetic spectrum.
The warming of earth due to the atmospheric accumulation of carbon dioxide, and certain other gases, which absorb infrared radiation and radiate some of it back toward Earth.
Increase in temperature and change in weather patterns all around the planet, due mostly to increasing atmospheric carbon dioxide levels from the burning fossil fuels. The increase in temperature, called global warming, is a major aspect of global climate change.
range of all possible frequencies of electromagnetic radiation.
Conversion of inorganic carbon to organic compounds by living organisms Rubisco. Takes place in a dark reaction.
Green pigment found in chloroplasts, allows plants to absorb energy from light. (Absorbs blue portion of electromagnetic spectrum best, followed by the red.)
The first in two stages in photosynthesis; the steps in which solar energy is absorbed and converted to the chemical energy of ATP and NADPH, releasing oxygen in the process.
Nicotinamide adenine dinucleotide phosphate, an electron acceptor that, as NADPH, temporarily stores energized electrons produced during the light reactions.
An organism that obtains energy from sunlight and carbon from carbon dioxide by photosynthesis.
A photon is an elementary particle, the quantum of light and all other forms of electromagnetic radiation. It is the force carrier for the electromagnetic force,
refers to the use of light energy from photosynthesis to ultimately provide the energy to convert ADP to ATP, thus replenishing the universal energy currency in living things.
In a plant cell, a metabolic pathway that consumes oxygen, releases carbon dioxide, and decreases photosynthetic output. Photorespiration generally occurs on hot, dry days when stomata close, oxygen accumulates in the leaf, and rubisco fixes oxygen rather than carbon dioxide. Photorespiration produces no sugar molecules or ATP.
The process by which plants, algae, and some protists and prokaryotes convert light energy to chemical energy that is stored in sugars made from carbon dioxide and water.
Microscopic pores surrounded by guard cells in the epidermis of a leaf. When stomata are open, carbon dioxide enters a leaf, and water and oxygen exit. A plant conserves water when its stomata are closed.
The dense fluid that surrounds the chloroplast and is involved in the synthesis of organic molecules from carbon dioxide and water. Sugars are made in the stroma by the enzymes of the Calvin cycle.
A flattened membranous sac inside a chloroplast. Thylakoid membranes contain chlorophyll and the molecular complexes of the light reactions of photosynthesis. A stack of thylakoids is called a granum.
