energy from nutrients into ATP, and then release waste products.
光合作用以二氧化碳和水为原材料并经历两步化学反应。
第一步，称光反应，水分子裂解 (被氧化)，释放氧气，并形成ATP和 NADPH（还原型烟酰胺腺嘌呤二核苷酸磷酸）。
此反应必须在存在光能的条件下进行。

Introduction
光合作用只发生在含有叶绿素的绿色植物细胞、藻类、某些原生生 物和细菌之中。
总体来说，这是一个将光能转化成化学能的过程，其能量以分子 键形式贮存。
从化学和能量学角度来看，它是细胞呼吸作用的逆反应。
但是细胞呼吸作用是高度放能，释放能量的过程，而光合作用需 要能量, 并且是高度吸能的过程。
在光合作用的光反应中，当捕光分子回到基态时，额外的激发能 被转移到其它分子中并且以化学能的形式贮存。
•All photosynthetic organisms contain various classes of
chlorophylls and one or more carotenoid pigments that also contribute to photosynthesis.
captured by biological molecules to do constructive work.
生物分子能捕获可见光谱中光子的能量。
The pigment chlorophyll in plant cells absorbs photons within a particular absorption spectrum—a statement of the amount of light absorbed by chlorophyll at different wavelengths.

1.1 What is Biology?
Biology is the study of life. Alongside physics and chemistry, biology is one of the largest and most important branches of science. At the highest level, biology is broken down based on the type of organism being studied: zoology, the study of animals; botany, of plants; and microbiology, of microorganisms. Each field has contributed to mankind or the Earth’s wellbeing in numerous ways. Most prominently: botany, to agriculture; zoology, to livestock and protection of ecologies; and microbiology, to the study of disease and ecosystems in general.

The genomic formula of the alien chromosomes in TE253 was 2 St + 8 J S + 2 J + 2 J-St.
The problem which haven't solved
We are presently developing chromosome addition and substitution(替换) lines to identify(确认) the chromosome location of the powdery mildew and stripe rust resistance(抗性) genes.
The problem need to be solve
In this study, we determined the genomic composition of a partial amphiploid TE253 by GISH probed with St genomic DNA from Ps. strigosa and evaluated its resistance to both powdery mildew and stripe rust as well. 我们通过基因组原位杂交探测从Ps. Strigosa到St基 因组确定了局部TE253基因的组成，并且还评估了 对白粉病和条锈病的抗性。
The method of the study
Cytogenetic Analyses(细胞遗传学分析）
其基本原理是用不同荧光物质分别标记病变细胞DNA 和正常细胞然后与正常中期细胞染色体杂交。 荧光原位杂交技术 用荧光物质标记特异性DNA探针，与中期细胞染色体 或间期细胞核杂交，鉴别和确定出生缺陷、肿瘤细胞 染色体异常，分辨率可达50~500kb。

1.Cytoplasm: The Dynamic, Mobile Factory 细胞质：动力工厂
Most of the properties we associate with life are properties of the cytoplasm. Much of the mass of a cell consists of this semifluid substance, which is bounded on the outside by the plasma membrane. Organelles are suspended within it, supported by the filamentous network of the cytoskeleton. Dissolved in the cytoplasmic fluid are nutrients, ions, soluble proteins, and other materials needed for cell functioning. 生命的大部分特征表现在细胞质的特征上。细胞质大部分由 半流体物质组成，并由细胞膜（原生质膜）包被。细胞器悬 浮在其中，并由丝状的细胞骨架支撑。细胞质中溶解了大量 的营养物质，离子，可溶蛋白以及维持细胞生理需求的其它 物质。
