5.初二上期期中各科復(fù)習(xí)提綱
你好！我有生物和物理的，希望可以幫到你！ 八年級(jí)生物上冊(cè)期中考試復(fù)習(xí)提綱一、水中生活的動(dòng)物1、目前已知的動(dòng)物約150萬(wàn)種，按有無(wú)脊柱分為脊椎動(dòng)物和無(wú)脊椎動(dòng)物兩大類(lèi)。
按生活環(huán)境分為陸地生活動(dòng)物、水中生活動(dòng)物和空中生活動(dòng)物。2、水生動(dòng)物最常見(jiàn)的是魚(yú)，此外，還有 ①腔腸動(dòng)物，如?？⑸汉飨x(chóng)；②軟體動(dòng)物，如烏賊、章魚(yú)； ③甲殼動(dòng)物，如蝦、蟹；④海豚（哺乳動(dòng)物）、龜（爬行動(dòng)物）等其他水生動(dòng)物。
3、魚(yú)適應(yīng)水中生活最重要的兩個(gè)特點(diǎn)：①能靠游泳來(lái)獲取食物和防御敵害。 ②能在水中呼吸。
4、四大家魚(yú)是：青魚(yú)、鰱魚(yú)、草魚(yú)和鳙魚(yú)。5、魚(yú)是較低等的脊椎動(dòng)物。
6、魚(yú)的外形呈梭形，其作用是：減少游泳阻力，適于游泳。魚(yú)體分三大部分：頭部、軀干部和尾部。
8、魚(yú)在游泳時(shí)主要靠身體軀干部和尾鰭的左右擺動(dòng)擊動(dòng)水流產(chǎn)生前進(jìn)的動(dòng)力，其它魚(yú)鰭起輔助作用。魚(yú)在運(yùn)動(dòng)時(shí)，背鰭、胸鰭、和腹鰭都有維持平衡的作用，尾 鰭有決定魚(yú)運(yùn)動(dòng)方向的作用。
9、魚(yú)的感覺(jué)器官是側(cè)線（感覺(jué)水流、測(cè)定方向）。10、魚(yú)鰓為鮮紅色，因?yàn)閮?nèi)含豐富的毛細(xì)血管；鰓絲既多又細(xì)，其作用是大大增加了跟水的接觸面積，促進(jìn)血和外界進(jìn)行氣體交換。
12、水由魚(yú)口流入鰓，然后由鰓蓋后緣（鰓孔）流出。在水流經(jīng)鰓絲時(shí)，水中溶解的_氧氣_進(jìn)入鰓絲的毛細(xì)血管中，而二氧化碳由鰓絲排放到水中；所以經(jīng)鰓流出的水流與由口流入的水流相比，氧氣的含量減少，二氧化碳的含量增高。
13、魚(yú)類(lèi)的主要特征有：適于水中生活；體表被鱗片；用鰓呼吸；通過(guò)尾部的擺動(dòng)和魚(yú)鯽的協(xié)調(diào)作用游泳。14、海葵、海蜇、珊瑚蟲(chóng)等動(dòng)物的結(jié)構(gòu)簡(jiǎn)單，它們有口無(wú)肛門(mén)，食物從口進(jìn)入消化腔，消化后的食物殘?jiān)杂煽谂懦鲶w外。
這些動(dòng)物稱(chēng)為腔腸動(dòng)物。15、像河蚌、蛾螺等身體柔軟靠貝殼來(lái)保護(hù)身體的動(dòng)物稱(chēng)為軟體動(dòng)物。
烏賊、章魚(yú)貝殼退化，也是軟體動(dòng)物。16、蝦類(lèi)和蟹類(lèi)等體表長(zhǎng)有質(zhì)地堅(jiān)硬的甲，叫甲殼動(dòng)物。
17、水中的各種生物都是水域生態(tài)系統(tǒng)的重要組成部分。它們之間通過(guò)食物鏈和食物網(wǎng)，形成緊密而復(fù)雜的聯(lián)系，同時(shí)又都受水域環(huán)境的影響，其種類(lèi)的變化和數(shù)量的消長(zhǎng)都會(huì)影響到人類(lèi)的生活。
18、海馬是魚(yú)類(lèi)，鯨、海豚、海豹是哺乳動(dòng)物，龜、海龜是爬行動(dòng)物。二、陸地生活的動(dòng)物-------蚯蚓1、陸地環(huán)境特點(diǎn)與陸生動(dòng)物的適應(yīng)：①氣候干燥……有防止體內(nèi)水分散失的結(jié)構(gòu)，如爬行動(dòng)物有角質(zhì)的鱗或甲，昆蟲(chóng)有外骨骼. ②缺少水的浮力……具有支持軀體和運(yùn)動(dòng)的器官.，有多種運(yùn)動(dòng)方式. 如：爬行、行走、跳躍、奔跑、攀援等，以便覓食和避敵。
③氣態(tài)氧供呼吸……具能在空氣中呼吸的、位于身體內(nèi)部的呼吸器官，如肺和氣管（蚯蚓例外，靠體壁呼吸） ④晝夜溫差大，環(huán)境變化快而復(fù)雜……有發(fā)達(dá)的感覺(jué)器官和神經(jīng)系統(tǒng)，對(duì)多變環(huán)境及時(shí)作出反應(yīng)。2、蚯蚓生活富含腐殖質(zhì)的濕潤(rùn)土壤中，通過(guò)肌肉和剛毛的配合使身體蠕動(dòng)，靠能分泌粘液、始終保持濕潤(rùn)的體壁呼吸。
可根據(jù)環(huán)帶著生在身體前端來(lái)判斷首尾（環(huán)帶也叫生殖帶）。3、蚯蚓身體分節(jié)的意義：可使蚯蚓的軀體運(yùn)動(dòng)靈活自如、轉(zhuǎn)向方便。
4、用手指觸摸蚯蚓體節(jié)近腹面處，有粗糙不平的感覺(jué)，用放大鏡觀察，看到腹面有許多小突起就是剛毛，剛毛的作用是協(xié)助運(yùn)動(dòng)（固著；支持）5、蚯蚓在潮濕土壤的深層穴居的原因：因?yàn)槟転轵球咎峁┻m宜的生存、生活的環(huán)境及繁衍的條件，一般包括適宜的溫度、濕度、氣態(tài)氧、食物和便于避敵的棲息場(chǎng)所等。6、在觀察蚯蚓的實(shí)驗(yàn)中為什么要經(jīng)常用浸水的濕棉球輕擦蚯蚓體表，使體表保持濕潤(rùn)：蚯蚓沒(méi)有呼吸系統(tǒng)，要靠能分泌粘液、始終保持濕潤(rùn)的體壁呼吸。
7、蚯蚓的生活環(huán)境：具有一定溫度和濕度、溫差變化不大、富含腐殖質(zhì)的土壤中穴居生活。生活習(xí)性和食性：一般晝伏夜出，以植物的枯葉、朽根和其他有機(jī)物為食。
8、大雨過(guò)后蚯蚓會(huì)紛紛爬到地面上來(lái)原因：大雨過(guò)后，過(guò)多的雨水會(huì)將土壤中的空氣排擠出去，于是穴居的蚯蚓被迫爬到地表上來(lái)呼吸。9、蚯蚓的呼吸過(guò)程：蚯蚓的體壁密布毛細(xì)血管，空氣中的氧氣先溶解在體表粘液里，然后進(jìn)入體壁的毛細(xì)血管中。
體內(nèi)的二氧化碳也經(jīng)體壁的毛細(xì)血管有體表排出。10、身體由許多相似的環(huán)狀體節(jié)構(gòu)成的動(dòng)物叫環(huán)節(jié)動(dòng)物，如蚯蚓、沙蠶、水蛭。
三、陸地生活的動(dòng)物-------兔1、哺乳動(dòng)物：具胎生、哺乳（后代成活率高），體表被毛，體溫恒定等特征.如兔、大熊貓2、恒溫動(dòng)物：可通過(guò)自身的調(diào)節(jié)而維持體溫的恒定，使體溫不隨外界的變化而變化的動(dòng)物，包括鳥(niǎo)類(lèi)和哺乳動(dòng)物.反之，體溫隨環(huán)境溫度變化而改變的動(dòng)物是變溫動(dòng)物，如蛇、昆蟲(chóng)等。恒溫意義：減少對(duì)外界環(huán)境依賴(lài)性，擴(kuò)大生活和分布范圍3、兔：體表被毛（保溫作用），用肺呼吸，心臟四腔，體循環(huán)和肺循環(huán)兩條途徑，體溫恒定，牙分門(mén)齒和臼齒，盲腸發(fā)達(dá)（在細(xì)菌作用下，有助于植物纖維質(zhì)的消化），大腦發(fā)達(dá)，四肢發(fā)達(dá)靈活。
4、跳躍是兔的主要運(yùn)動(dòng)形式（后退比前腿長(zhǎng)且肌肉發(fā)達(dá)）。5、兔的食性：植物（草）。
兔的身體分為：頭、軀干、絲織和尾四部分。6、兔的牙齒分化為門(mén)齒和臼齒。
門(mén)齒似鑿子適于切斷食物，臼齒咀嚼面寬闊適于磨碎食物。兔的盲。
