Photosynthesis

chloroplasts

"absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant. They capture light energy from the sun to produce the free energy stored in ATP and NADPH through a process called photosynthesis.

grana

"one of the two membranes inside the organelle chloroplasts that forms stacks that contain a green pigment, called chlorophyll that absorbs light energy.

Photosynthesis

"the process by which plants, algae, and some bacteria use sunlight, carbon dioxide, and water to make food; Plants capture energy from sunlight during photosynthesis. This energy is used to make the sugar glucose (C6H12O6) from carbon dioxide (CO2) and water (H2O).

Kinds of Fermentation

One kind of fermentation happens in your muscles and produces lactic acid. The second type of fermentation occurs in some types of bacteria and in yeast

Pigments

Plant cell molecules that absorb light energy

photosynthesis chemical equation:

Six molecules of carbon dioxide and six molecules of water are needed to form one molecule of glucose and six molecules of oxygen.

Glucose

a carbohydrate that plants make, they convert the sun's energy into a form of energy that can be stored. The energy is then used by the plant's cells.

Cellular respiration

a chemical process that occurs in the cells; process by which cells use oxygen to produce energy from breaking down food and give off carbon dioxide and water; this method releases more energy than fermentation

Sunlight

made up of many different wavelengths of light. Chlorophyll absorbs many of these wavelengths. But it reflects more wavelengths of green light than wavelengths of other colors of light. So, most plants look green.

stoma

one of many openings in a leaf or a stem of a plant that enable gas exchange to occur during light the stoma is open for photosynthesis and at night they are closed.

Photosynthesis and Respiration

photosynthesis transforms energy from the sun into glucose. During photosynthesis, cells use CO2 to make glucose, and the cells release O2. During cellular respiration, cells use O2 to break down glucose and release energy and CO2. Each process makes the materials that are needed for the other process to occur elsewhere.

Fermentation

the breakdown of food without the use of oxygen produces less energy than cellular respiration

Chlorophyll

the main pigment used in photosynthesis, gives plants their green color. Chlorophyll is found in chloroplasts. Plants use the energy captured by chlorophyll to change carbon dioxide and water into food. The food is in the form of the simple sugar glucose.

transpiration

the process by which plants release water vapor into the air through stomata; also the release of water vapor into the air by other organisms stomata are open
