1.植物都係生物,所以會呼吸 (生物必需既7個條件...你應該知卦)
(all the plants are living thing,so they can breathe...)
2....據我所知...植物只會係進行光合作用既時候會吸二氧化碳...
(i just know that , all the plants take in carbon dioxide when they make food by themself)
3.我諗你應該知植物要係陽光下進行光合作用...而進行光合作用既時候會吸二氧化碳...
(when plants make food be themself,they should have sunlight and carbon dioxide...so they take in carbon dioxide under sunlight...)
我5知你要中定英...所以2樣都有write...

你答案(１)果度打錯字 係respire 唔係redpire
(１)基本上任何植物係任何時候都係進行呼吸
(２)植物只係會吸取 carbon dioxide 唔會放 carbon dioxide
(３)因為係陽光下 植物會進行光合作用 所以係吸取 carbon dioxide
2007-12-08 17:10:27 補充：
但係晚上果陣都係好似會放carbon dioxide 不過係好少量 唔好意思 因為我都係讀緊中３ 我都唔係好清楚
