Photosynthesis Every living thing needs _______________________. All _________________ need energy to carry out their functions, such as making proteins and transporting substances into and out of the cell. The process by which a cell ____________________ energy in sunlight and uses it to make food is called _____________________. During ______________________, plants and some other organisms use energy from the __________ to convert carbon dioxide and water into oxygen and sugars, including __________________. You can think of photosynthesis as taking place in two stages: ___________________ the sun’s energy and producing ________________________. In plants, this energy-capturing process occurs in the ________________________ and green parts of the plants. In most plants, leaf cells contain more __________________________ than do cells in other parts of the plant. The main pigment in chloroplast is ____________________. Chlorophyll and other pigments function in a manner similar to that of the solar “cells” in a solarpowered ______________________________. The chlorophyll captures the ___________________ in light and use it to power the second stage in photosynthesis. In the second stage of photosynthesis, the cell uses the captured _________________ to produce ___________________. The cell needs two raw materials for this stage, ______________________ and ____________________. In plants, the _________________ absorbs the water from the soil. Then the water moves up the stem to the ___________________. Carbon _________________________ is one of the gases in the air. It enters the leaves through openings on the underside of the leaf called ______________________. Once in the leaves, the ____________________ and _________________________ dioxide move into the _________________________. Inside the chloroplast, the water and carbon dioxide undergo a complex series of chemical reactions. The plant is an ________________________ because it makes its own food. An caterpillar or anything that can not make its own _______________________ is called a ____________________________. Nearly all living things obtain energy either ___________________________ or _____________________ from the energy of sunlight captured during photosynthesis.
