26.【解答】(1)B .词意推断题.根据 Chlorophyll helps photosynthesis. It gives plants their green color. Chlorophyll_于光合 .赋予植物绿色.故选B. (2)A.细节理解题.根据 Trees rest during this time and live on the food they store during the summer. 树木在这段时间休息, 并以在夏季储存的食物为...
由第三段第一句 A chemical called "chlorophyll" helps photosynthesis 以及第二句 It gives plants their green colour 可知,这种叫做chlorophyll的化学物质在光合作用中发挥作用,并且使植物呈现绿色。因此,这种化学物质为“叶绿素”。故正确答案为B。2. 细节题。由第四段第二句Trees rest during this time and ...
Plans use this sugar as food for energy and for growing.The way plants tum water and carbon dioxide into sugar is called photosynthesis (光合作用). A chemical called chlorophyll (叶绿素)helps photosynthesis. Chlorophyll gives plants their green color. As summer ends and autumn comes, days get ...
A chemical called chlorophyll helps make photosynthesis happen. Chlorophyll is green. It gives plants their green colour. As summer ends and autumn comes, the days get shorter and shorter. This is how the trees “know” to begin getting ready for winter. During winter, there is not enough ...
A chemical called chlorophyll (叶绿素) helps photosynthesis. Chlorophyll is what gives plants their green color. As summer ends and autumn comes, the days get shorter and shorter. This is how trees “know” to begin getting ready for winter. ...
To understand how photosynthesis and respiration are related to each other, we can break down the processes step by step:Step 1: Define Photosynthesis Photosynthesis is the process by which green plants, algae, and some bacteri
Plants make their own food using a process calledphotosynthesis. During photosynthesis, the chlorophyll-containing green parts of the plant trap light energy and use it to perform a series of chemical reactions. The process involves carbon dioxide, and so plants also need plenty of air. We usuall...
Applying too much molasses by not diluting it enough or applying it too frequently can cause sugar to build up on the leaves and in the soil. Sugar attracts pests to your garden. Additionally, a layer of sugar on the leaves can inhibit photosynthesis. ...
As we all know, plants are the primary producers in thefood chain. The leaves contain chlorophyll, which helps inphotosynthesis(making food). However, a seed that has not yet grown leaves manages to survive with the starch stored inside the cotyledons of the seed. Once the seed bursts, the...
There are two substages in the light-dependent process of photosynthesis. Firstly, photosystem II oxidizes H2O to oxygen using the energy from sunlight captured by chlorophyll. This process, also known as photolysis of water or splitting of the H20 molecule, produces excited electrons. Simultaneously...
