適應(yīng)、影響和改變

一、生物與環(huán)境的關(guān)系

影響

環(huán)境

二、生態(tài)因素：環(huán)境中影響生物的生活和分布的因素稱(chēng)為生態(tài)因素。

非生物因素的影響

光照、溫度、水、空氣等

生物因素的影響

種內(nèi)關(guān)系

【指同種生物之間的關(guān)系】

種內(nèi)斗爭(zhēng)

指同種動(dòng)物之間為了爭(zhēng)奪食物、棲息場(chǎng)所和配偶等發(fā)爭(zhēng)奪。

如：兩只狗為爭(zhēng)奪食物而發(fā)生“狗咬狗的爭(zhēng)斗”“一山容不得二虎”等。

種內(nèi)互助

指同種生物之間的協(xié)助。如：成群的?？梢杂行У貙?duì)付

狼群的攻擊等。最典型的存在于營(yíng)群體生活的動(dòng)物，如：

蜜蜂和螞蟻等。

種間關(guān)系

【指不同種生物之間的關(guān)

系】

捕食

指一種生物以另一種生物為食的現(xiàn)象。

如：七星瓢蟲(chóng)捕食蚜蟲(chóng)，獅子捕殺斑馬，斑馬吃草等。

競(jìng)爭(zhēng)

指兩種不同生物之間為了爭(zhēng)奪食物，生活空間或環(huán)境中的其他條件而發(fā)生的爭(zhēng)奪。

如：在稻田中水稻與水稻；

水稻與雜草之間爭(zhēng)奪陽(yáng)光、養(yǎng)料、水分；牛和羊爭(zhēng)奪青草；青蛙和鳥(niǎo)爭(zhēng)奪昆蟲(chóng)等。

三、生態(tài)系統(tǒng)的組成概

念

在一定的地域內(nèi)，生物與環(huán)境所形成的統(tǒng)一整體，叫做生態(tài)系統(tǒng)。

生態(tài)系統(tǒng)的組成非生物部分

陽(yáng)光、空氣、水、生存空間等

生物部分

生產(chǎn)者

植物能進(jìn)行光合作用，制造有機(jī)物、儲(chǔ)存能量，為植物體本身和其他生物以及人類(lèi)的生活提供

了必須的物質(zhì)和能量，因此，綠色植物在生態(tài)系統(tǒng)中是屬于生產(chǎn)者。還有些化能合成細(xì)菌，如：硫細(xì)菌、硝化細(xì)菌和藍(lán)藻等，它們?cè)谏鷳B(tài)系統(tǒng)中也是屬于生產(chǎn)者。

消費(fèi)者

動(dòng)物細(xì)胞中不含葉綠體，不能自己制造有機(jī)物，必須直接或間接地以綠色植物為食，所以，動(dòng)物在生態(tài)系統(tǒng)中是屬于消費(fèi)者。

分解者

腐生的細(xì)菌和真菌能把動(dòng)、植物尸體等復(fù)雜的有機(jī)物分解成簡(jiǎn)單的無(wú)機(jī)物，供綠色植物再利用。還有極少數(shù)的腐生動(dòng)物，如：蚯蚓、屎殼郎和白蟻等在生態(tài)系統(tǒng)中也是屬于分解者；分解者的主要作用是“促進(jìn)生態(tài)系統(tǒng)的物質(zhì)循環(huán)”。

聯(lián)

系

生產(chǎn)者、消費(fèi)者和分解者之間是相互依存、密切聯(lián)系、缺一不可的。

四、食物鏈和食物網(wǎng)

1.食物鏈的定義：不同的生物之間由于吃與被吃的關(guān)系而形成的鏈狀結(jié)構(gòu)。

2.食物鏈的組成：始于生產(chǎn)者，終于消費(fèi)者。

3.食物鏈中物質(zhì)可從生產(chǎn)者流向最高級(jí)的。

4.食物鏈中能量從生產(chǎn)者流向最高級(jí)的消費(fèi)者，能量單向流動(dòng)不可循環(huán)。

5.在一個(gè)生態(tài)系統(tǒng)中，很多條食物鏈彼此交錯(cuò)連接，形成食物網(wǎng)。

五、生物圈是最大的生態(tài)系統(tǒng)

1.生物上所有的圈的含義：

地球生物與其環(huán)境的總和就叫生物圈。

2.生物圈的范圍：

（1）大氣圈的底部

（2）水圈的大部

（3）巖石圈的表面

六、多種多樣的生態(tài)系統(tǒng)

類(lèi)型

名稱(chēng)

特點(diǎn)

作用

自然生態(tài)系統(tǒng)

草原生態(tài)系統(tǒng)

分布于干旱地區(qū)，降雨很少，缺乏大植

物，動(dòng)植物種類(lèi)比森林生態(tài)系統(tǒng)少

水土保持和防風(fēng)固沙

濕地生態(tài)系統(tǒng)

是多水和過(guò)濕條件下形成的生態(tài)系統(tǒng)。沼澤植物占優(yōu)勢(shì)，動(dòng)物種類(lèi)也很多

凈化水質(zhì)、蓄洪抗旱。有“地球之腎”之稱(chēng)

海洋生態(tài)系統(tǒng)

植物絕大部分是微小的浮游植物；動(dòng)物種類(lèi)繁多，大多能在水中游動(dòng)

能吸收大量的二氧化碳，海洋植物制造的氧氣占地球產(chǎn)生

氧氣總量的70%

森林生態(tài)系統(tǒng)

分布在較濕潤(rùn)地區(qū)，動(dòng)植物種類(lèi)繁多

涵養(yǎng)水源、保持水土、防風(fēng)固沙、調(diào)節(jié)氣候、凈化空氣等。有“綠色水庫(kù)”、“地球之

肺”之稱(chēng)

淡水生態(tài)系統(tǒng)

包括河流生態(tài)系統(tǒng)、湖泊生態(tài)系統(tǒng)、池塘生態(tài)系統(tǒng)等。由淡水水體和其中的生物組成為人類(lèi)提供飲水、灌溉及工業(yè)用水，還可以調(diào)節(jié)氣候

人工生態(tài)系統(tǒng)

農(nóng)田生態(tài)系統(tǒng)

以農(nóng)作物為主題，動(dòng)植物相對(duì)較少。農(nóng)作物抵抗旱澇或病蟲(chóng)害的能力較差，需要在栽培和管理中投入大量的人力物

力。

人工生態(tài)系統(tǒng)都比較脆弱，人的作用比較關(guān)鍵，容易退化

城市生態(tài)系統(tǒng)

人類(lèi)在這一生態(tài)系統(tǒng)中起著重要的支配作用。植物種類(lèi)和數(shù)量少，消費(fèi)者主要

是人類(lèi)。

七、能量流動(dòng)和物質(zhì)循環(huán)

（1）生態(tài)系統(tǒng)的能量流動(dòng)

生態(tài)系統(tǒng)中能量的最終來(lái)源是太陽(yáng)。能量流動(dòng)的特點(diǎn)是單向流動(dòng)，逐級(jí)遞減。

（2）生態(tài)系統(tǒng)的物質(zhì)循環(huán)

綠色植物的光合作用為動(dòng)物的生活提供了有機(jī)物和氧氣，而動(dòng)物的呼吸作用產(chǎn)生二氧化碳能提供植物進(jìn)行光合作用合成有機(jī)物，同時(shí)營(yíng)腐生生活的細(xì)菌和真菌能將動(dòng)物糞便，動(dòng)植物遺體中的有機(jī)物分解為無(wú)機(jī)物供植物重新利用。

自然界中的物質(zhì)是循環(huán)利用的，物質(zhì)被重復(fù)利用的同時(shí)提高了能量利用率

八、生態(tài)系統(tǒng)的自動(dòng)調(diào)節(jié)能力

（1）生態(tài)系統(tǒng)中，各種生物數(shù)量和所占比例是相對(duì)穩(wěn)定的，說(shuō)明生態(tài)系統(tǒng)具有一定的自動(dòng)調(diào)節(jié)能力。

（2）生態(tài)系統(tǒng)調(diào)節(jié)能力的大小主要取決于它自身的結(jié)構(gòu)特點(diǎn)。生態(tài)系統(tǒng)中生物種類(lèi)越多，營(yíng)養(yǎng)結(jié)構(gòu)越復(fù)雜，自動(dòng)調(diào)節(jié)能力就越強(qiáng)，生態(tài)平衡就不易被打破；反之，自動(dòng)調(diào)節(jié)能力就越弱，生態(tài)平衡就越容易被破壞。

第二單元

生物體的結(jié)構(gòu)層次

第一章

細(xì)胞是生命活動(dòng)的基本單位

第一節(jié)

練習(xí)使用顯微鏡

一、認(rèn)識(shí)顯微鏡

二、練習(xí)使用顯微鏡

1、取鏡和安放

右手握鏡臂，左手托鏡座。實(shí)驗(yàn)臺(tái)略偏左，安裝目鏡物鏡。

2、對(duì)光

①轉(zhuǎn)動(dòng)轉(zhuǎn)換器，低倍物鏡對(duì)準(zhǔn)通光孔。

②轉(zhuǎn)動(dòng)遮光器，較大光圈對(duì)準(zhǔn)通光孔。

③轉(zhuǎn)動(dòng)反光鏡，反射光線經(jīng)過(guò):通光孔—>物鏡—>鏡筒—>目鏡

對(duì)光完成的標(biāo)志：看到明亮的圓形視野。

▲核心要點(diǎn)：視野光線強(qiáng)弱需調(diào)節(jié)遮光器和反光鏡：

①當(dāng)視野光線太亮?xí)r，用小光圈和平面鏡；

②當(dāng)視野光線太暗時(shí)，用大光圈和凹面鏡。

3、觀察

①把玻片標(biāo)本放在載物臺(tái)上，用壓片夾壓住，同時(shí)正對(duì)通光孔的中心。

②順時(shí)針?lè)较蜣D(zhuǎn)動(dòng)粗準(zhǔn)焦螺旋，使鏡筒緩慢下降，直到物鏡接近玻片標(biāo)本為止。（此時(shí)，眼睛一定要從側(cè)面看著物鏡。目的：防止物鏡碰到玻片標(biāo)本。）

③左眼注視目鏡，右眼睜開(kāi)。同時(shí)逆時(shí)針?lè)较蜣D(zhuǎn)動(dòng)粗準(zhǔn)焦螺旋，使鏡筒緩緩上升直到看清物像為止。再略微轉(zhuǎn)動(dòng)細(xì)準(zhǔn)焦螺旋，使看到的物像更加清晰。

▲核心要點(diǎn)

：（1）從目鏡內(nèi)看到的物像是倒像。

（2）顯微鏡的放大倍數(shù)是目鏡與物鏡放大倍數(shù)的乘積。

（3）如果將標(biāo)本往左移動(dòng)，物像向右移動(dòng)。

（4）換成寫(xiě)有“上”字的玻片標(biāo)本，觀察到的現(xiàn)象是左右相反，上下顛倒（旋轉(zhuǎn)180度）。

（5）使用顯微鏡觀察物像時(shí)，如果物像不在視野中央，要是其移至視野中央，偏什么方向就往什么方向移動(dòng)標(biāo)本。概括:偏哪往哪移。例如：物像偏左上方，標(biāo)本就往左上方移動(dòng)。

（6）

顯微鏡視野中出現(xiàn)了一個(gè)污點(diǎn)。你有什么辦法判斷這個(gè)污點(diǎn)是在物鏡上還是在目鏡上？還是在玻片標(biāo)本上？

邊觀察邊移動(dòng)玻片，如果污點(diǎn)也跟著移動(dòng)，則污點(diǎn)在玻片上；

邊觀察邊轉(zhuǎn)動(dòng)目鏡，如果污點(diǎn)也跟著轉(zhuǎn)動(dòng)，則污點(diǎn)在目鏡上；

如果以上都試了，污點(diǎn)未跟著轉(zhuǎn)動(dòng)，則污點(diǎn)在物鏡上。

4、整理收鏡

用紗布擦拭顯微鏡，用擦鏡紙擦拭目鏡和物鏡。

第二章

細(xì)胞怎樣構(gòu)成生物體

第一節(jié)

細(xì)胞通過(guò)分裂產(chǎn)生新細(xì)胞

一、細(xì)胞的生長(zhǎng)

1、生物體由小長(zhǎng)大，是與細(xì)胞的生長(zhǎng)、分裂和分化分不開(kāi)的。

2、構(gòu)成生物體的細(xì)胞要不斷從周?chē)h(huán)境中吸取營(yíng)養(yǎng)物質(zhì)，并且轉(zhuǎn)變成組成自身的物質(zhì)，體積會(huì)由小變大，這就是細(xì)胞的生長(zhǎng)。細(xì)胞生長(zhǎng)的結(jié)果：細(xì)胞體積增大。

二、細(xì)胞的分裂

動(dòng)物細(xì)胞分裂過(guò)程

分裂時(shí)，細(xì)胞核先由一個(gè)分成兩個(gè)，隨后，細(xì)胞質(zhì)分成兩份，每份各含有一個(gè)細(xì)胞核。

細(xì)胞膜從細(xì)胞的中部向內(nèi)凹陷，縊裂為兩個(gè)細(xì)胞

植物細(xì)胞分裂過(guò)程

在原細(xì)胞的中央形成新的細(xì)胞膜和新的細(xì)胞壁

3、細(xì)胞分裂的結(jié)果：細(xì)胞數(shù)目增多。

4、在細(xì)胞分裂過(guò)程中，染色體的變化最為明顯。

（1）染色體是細(xì)胞核中被堿性染料染成深色的物質(zhì)。

（2）染色體是由DNA和蛋白質(zhì)兩種物質(zhì)組成的。

（3）DNA是遺傳物質(zhì)，因此可以說(shuō)染色體就是遺傳物質(zhì)的載體

5、細(xì)胞分裂過(guò)程中，細(xì)胞核中染色體的變化

（1）染色體的復(fù)制加倍。

（2）染色體平均分配到兩個(gè)新細(xì)胞里。

（3）兩個(gè)新細(xì)胞的染色體形態(tài)和數(shù)目相同。新細(xì)胞與原細(xì)胞的染色體形態(tài)和數(shù)目相同。新細(xì)胞和原細(xì)胞所含遺傳物質(zhì)是一樣的。

第二節(jié)

動(dòng)物體的結(jié)構(gòu)層次

一、細(xì)胞分化形成不同的組織——（細(xì)胞分化的結(jié)果：形成不同的組織）

1、動(dòng)物和人體的發(fā)育都是從一個(gè)細(xì)胞開(kāi)始的，這個(gè)細(xì)胞就是受精卵。受精卵通過(guò)細(xì)胞分裂產(chǎn)生新細(xì)胞。

2、在個(gè)體發(fā)育過(guò)程中，一個(gè)或一種細(xì)胞通過(guò)分裂產(chǎn)生的后代，在形態(tài)、結(jié)構(gòu)和生理功能上發(fā)生差異性的變化，這個(gè)過(guò)程叫做細(xì)胞分化。

3、每個(gè)細(xì)胞群都是由形態(tài)相似，結(jié)構(gòu)、功能相同的細(xì)胞聯(lián)合在一起形成的，這樣的細(xì)胞群叫做組織。

4、人體有四種基本組織——上皮組織、肌肉組織、結(jié)締組織、神經(jīng)組織
