Adaptation 适应性改变
Any inherited structure, behavior, or internal process that enables an organism to respond to environmental factors and live to produce offspring is called an adaptation.
Evolution 进化
征子
The gradual change in a species through adaptations over time is evolution.
Growth 生长
路由器的线怎么插Growth results in an increa in the amount of living meterial and the formation of new structures.
Reproduction 繁殖
One of the most obvious of all the characteristics of life is reproduction, the production of offspring.
Species 物种
A species is a group of organisms that can interbreed and produce fertile offspring in nature.
Stimulus 刺激
Anything in an organism’s external or internal environment that caus the organism to react is a stimulus.
Dependent variable 因变量
The condition that any changes in it depend on changes made to the independent variable is called dependent variable.突如其来的反义词
Independent variable 自变量
The condition in an experiment that is tested is the independent variable.
Ecology 生态学
Ecology is the study of interactions that take place between organisms and their environment.
Ecosystem 生态系统
An ecosystem is made up of interacting populations in a biological community and the community’s abiotic factors.
考研辅导班收费Niche 小生境
A niche is all strategies and adaptations a species us in its environment.
Autotroph 自养生物
An organism that us light energy or energy stored in chamical compounds to make energy-rich compounds is a producer, or autotroph.
Heterotroph 异养生物
An organism that cannot make its own food and feeds on other organisms is called a heterotroph.
Food chain 食物链
A food chain is a simple model that species u to show how matter and energy move through an ecosystem. In a food chain, nutrients and energy move from autotrophs to heterotrophs and, eventually, to decompors.
Limiting factor 限制因素
A limiting factor is any biotic or abiotic factor that restricts the existence, numbers, reproduction, or distribution of an organisms.
Tolerance 耐受性
大学学业规划The ability of an organism to withstand fluctuations in biotic and abiotic environmental factors is known as tolerance.
Primary succesion 原生演替
The colonization if barren land by communities of organisms is called primary succesion. 原生演替（ primary succession ） 在完全没有植物的基础上，如海洋上隆起的新岛，火山的溶岩流，新形成的湖沼等地方因植物移居发生的演替
Carrying capacity 环境容量
The number of organisms of one species that an environment can support indefinitely is its carrying capacity.
小鸟叫的声音Exponential growth 指数增长
Exponential growth means that as a populetion get larger, it also grows at a faster rate.
Biodiversity 生物多样性
Biodiversity refers to the variety of species in a specific area.
Endangered species 濒危物种
A species is considered to be an endangered species when its numbers become so low that extinctions is possible.玉米粒饼的做法
Extinction 灭绝
Extinction is the disappearance of a species when the last of its members dies.电影放牛班的春天
Diffusion 扩散
Diffusion is the net movement of particles from an area of higher concentration to an area of lower concentration.
Organelle 细胞器
With the development of better mocroscopes, scientists obrved that all cells contain small, specialized structures called organelles, such as mitochondria, chloroplast and ribosme.
Nucleus 细胞核
The central membrane-bound organelle that manages or controls cellular functions is called the nucleus.
Plasma membrane 细胞质膜
Plasma membrane is the flexible boundary between the cell and its environment, to allow a steady supply of the nutrients to come into the cell no matter what the external conditions are.
Selective permeability 选择通透性
Selective permeability is a process in which a membrane allows some molecules to pass through while keeping others out.选择透过性专指细胞膜上膜蛋白的选择透过作用。如选择K+和N+进入细胞膜
Phospholipid 磷脂
A phospholipid has a glyceral backbone, two fatty acid chains, and a pgosphate group.含有一个或多个磷酸基的脂质。是构成细胞膜的主要脂分子
Transport protein 转运蛋白
Transport proteins move needed substances or waste materials through the plasma membrane.在叶绿体内膜上有很多运输蛋白选择性转运出入叶绿体的分子。叶绿体内膜上所有转运蛋白的运输作用都是靠浓度梯度驱动的,而不是主动运输。这不仅与细胞质膜的运输蛋白不同,也与线粒体内膜的运输系统不同,在线粒体内膜中也有主动运输的转运蛋白
Chloroplast 叶绿体
Chloroplasts are cell organelles that capture light energy and convert it to chemical energy.植物细胞中由双层膜围成，含有叶绿素能进行光合作用的细胞器。间质中悬浮有由膜囊构成的类囊体，内含叶绿体DNA。
Chlorophyll 叶绿素
Chlorophyll traps light energy and gives leaves and stems their green color.植物叶绿体内含有卟啉环的主要光合作用色素。可吸收光能用于光合作用
