动物细胞会严重失水.
因为,细胞膜是一种半透膜,尿素可以自由出入,而细胞内的大分子不能渗到胞外,这样溶液中的尿素渗透势肯定要低于细胞内尿素的渗透势,水往渗透势低的地方流,所以细胞会失水,又因为一个细胞相对1升尿素溶液而言,相差太大,细胞等于被干燥了.
在一个动物细胞内如果植入1-L urea 浓度的溶液与细胞内的溶质总量相同,会发生什么?
完全不明白生物的人啊。
如果动物细胞放入1升的尿素培养液(浓度和该细胞的细胞质一样)里,会是什么情况呢?
问题翻译过来是 如果把动物细胞放入1升的尿素培养液(浓度和该细胞的细胞质一样)里,会发生什么?
细胞保持动态平衡,因为细胞膜内和外界不存在浓度差
在动物细胞中发生,如果它被放置在一个与细胞内的溶质的总浓度相同1-L的尿素溶液会怎样呢?
绝对正确望采纳
这题是要干嘛?
