from Chapter 17 / Lesson 22 70K Photosynthesis has a relatively simple balanced chemical equation. Take a look at an introduction to photosynthesis and chemical reactions, then observe the specific photosynthesis chemical reactions and this balanced chemical equation. Related...
It can purify air, carries on the photosynthesis, carbon dioxide into oxygen, trees can save a lot of ground water, prevent soil erosion, solid earth, also can withstand the sand. How important the trees are! We can think of environmental protection as a force, and we can beautify the en...
Photosynthesis is a natural process that occurs in plants and algae. It is a reaction that allows life forms on Earth to thrive, and provides the energy necessary for survival.Answer and Explanation: Photosynthesis is the chemical reaction in which plants and algae make their own food by using...
Biomass energy refers to the energy form of solar energy stored in biomass in the form of chemical energy, which basically comes from the photosynthesis of green plants on earth and can be converted into conventional solid, liquid and gaseous fuels. Plants wither and bloom, spring breeze again,...
根据“Trees get less sunlight, so photosynthesis slows down. Over time, leaves stop making the green chemical."可知,在秋天树木受到的阳光较少,因此光合作用减慢。随着时间的推移,叶子停止制造绿 色化学物质。 故选D。 14.词句猜测题。根据“Once it gets cold enough and ice appears at night, the ...
The main ingredients required for photosynthesis are: - Carbon dioxide (CO2), which comes from the air. - Water (H2O), which is absorbed from the soil. - Light, which is obtained from the sun. 5. By-Product of Photosynthesis: One of the important by-products of photosynthesis is oxygen...
Plants, algae, and some types of bacteria use photosynthesis to create energy. A large percentage of the Earth’s oxygen comes from phytoplankton in the oceans, which contain chlorophyll and use photosynthesis to create energy. What is chlorophyll? Chlorophyll is a green pigment which absorbs energ...
5.【答案】When the roots and leaves of a tree are fully grown, the tree can then produce its own food and also provide oxygen into the atmosphere through a process called photosynthesis.【解析】本题主要是从文章中找信息。题目问的是树是怎么生存和生长的。结合全文,发现于第三大部分——How ...
In the broadest sense, photosynthesis and cellular respiration are very similar. Though they are used by different organisms, both processes are used to create energy molecules. However, the two processes are actually quite different when you look closely....
During photosynthesis,chlorophyll takes in sunlight. This gives the plant energy. The leaves use the energy to mix CO, with water. This helps food production.In autumn, days become shorter and shorter.There is less sunlight for the plants. When winter comes, there is less water in the air....
