在講述細(xì)胞分化的意義時(shí)，也可以用實(shí)例來(lái)解決，工廠(chǎng)的生產(chǎn)車(chē)間里不同的工人干著不同的工作，一件產(chǎn)品的產(chǎn)出需要這些工人才能創(chuàng)造出來(lái)，一個(gè)生物體就像一個(gè)車(chē)間一樣，不同的細(xì)胞各司其職，相互合作。工人的分工是主管調(diào)解出來(lái)的，而不同細(xì)胞的出現(xiàn)就是細(xì)胞分化的結(jié)果，所以說(shuō)，細(xì)胞的分化是生物體發(fā)育的基礎(chǔ)。在講到細(xì)胞全能性的時(shí)候，要多給學(xué)生舉些關(guān)于細(xì)胞全能性的例子，如植物組織培養(yǎng)、克隆技術(shù)等等，讓學(xué)生從實(shí)際的例子中真正的悟出細(xì)胞全能性的含義。此外，還要重視教材中的疑問(wèn)，適當(dāng)對(duì)題目進(jìn)行引申,使它的作用更加突出，有利于學(xué)生對(duì)知識(shí)的串聯(lián)、積累、加工，從而達(dá)到舉一反三的效果。怎樣來(lái)解釋細(xì)胞的全能性呢？這主要以講授法來(lái)解釋了，細(xì)胞全能性的體現(xiàn)需要在組織或器官離體后才能體現(xiàn)出來(lái)，每個(gè)細(xì)胞都包含著生物體的全套遺傳基因，通過(guò)基因選擇性的表達(dá)，使離體的組織或器官通過(guò)分裂和分化逐漸發(fā)育成完整的植株。

尊敬的學(xué)校領(lǐng)導(dǎo)、老師，親愛(ài)的同學(xué)們：大家早上好！今天我講話(huà)的題目是“發(fā)展藝術(shù)教育提高審美情趣”。近期不少教育界、學(xué)術(shù)界的有識(shí)之士呼吁，國(guó)民藝術(shù)教育應(yīng)該成為人們關(guān)注的一個(gè)社會(huì)問(wèn)題。這里所說(shuō)的藝術(shù)教育，不同于培養(yǎng)專(zhuān)門(mén)藝術(shù)人才的專(zhuān)業(yè)教育，而是指提高同學(xué)們的文化修養(yǎng)、鑒賞能力、審美情趣。藝術(shù)素質(zhì)教育的目的集中在人格的培養(yǎng)上。注重培養(yǎng)智力為知的素質(zhì)，氣質(zhì)為情的素質(zhì)，性格為意的素質(zhì)，能力為技的素質(zhì)是我們追求的目標(biāo)。藝術(shù)教育是滲透性教育即在語(yǔ)文、 數(shù)學(xué)、英語(yǔ)等學(xué)科教學(xué)中滲透藝術(shù)教育。它對(duì)于陶冶人們的思想情操，提高人的審美情趣，使人樹(shù)立崇高的審美理想，具有其它教育所不可替代的作用。拿藝術(shù)教育中的美術(shù)教育來(lái)說(shuō)，它是通過(guò)各種教學(xué)實(shí)踐活動(dòng)，使同學(xué)們?cè)谥苯痈惺苤辛私?、認(rèn)識(shí)美，在感知中理解鑒賞美，在感悟中體現(xiàn)和創(chuàng)造美，從而達(dá)到較深刻的審美意識(shí)。魯迅先生曾指出：“美術(shù)可以輔翼道德，美術(shù)之目的，雖與道德不盡符，然其力足以淵邃人之性情，崇高人之好尚，亦可輔道德以為治?！庇纱丝梢?jiàn)，美術(shù)能陶冶人的情操，凈化人的心靈，豐富人的感情，讓人們心身健康地發(fā)展，培養(yǎng)人的高尚品德和審美意識(shí)，使人樹(shù)立正確的人生觀(guān)……

四、說(shuō)教學(xué)程序（一）.溫故知新、導(dǎo)入新課復(fù)習(xí)提問(wèn):基因突變導(dǎo)致生物變異的原因是什么?回答:基因突變是基因結(jié)構(gòu)發(fā)生改變，從而使遺傳信息改變，使蛋白質(zhì)結(jié)構(gòu)改變、生物性狀改變，即生物發(fā)生了變異。那么，基因是什么?它和染色體又有何關(guān)系?回答:基因是有遺傳效應(yīng)的DNA片斷，染色體是DNA的載體，基因在染色體上呈線(xiàn)形排列。引出新知:對(duì)于一個(gè)生物體來(lái)說(shuō)，正常情況下，其染色體的結(jié)構(gòu)和數(shù)量都是穩(wěn)定的。但在自然條件或人為因素的影響下，染色體的結(jié)構(gòu)和數(shù)量均會(huì)發(fā)生改變，從而導(dǎo)致生物性狀的改變，這就屬于染色體變異。（二）.把握重點(diǎn)、突破難點(diǎn)重點(diǎn)的把握：1、染色體結(jié)構(gòu)的變異播放影片:貓叫綜合征幼兒。讓學(xué)生觀(guān)察: 患兒哭聲輕、音調(diào)高，很像貓叫。教師補(bǔ)充: 患兒的征狀---兩眼較低、耳位低下，存在著嚴(yán)重的智力障礙。闡述病因---染色體片段缺失
