係研究photosynthetic rate experimental set up 加sodium hydrogencarbonate solution 係 provide carbon dioxide for photosynthesis to occur 定係increase amount of carbon dioxide in water hence increase photosynthetic rate

我冇題目，所以我唔知你個情況係咪咁。
我假設carbon dioxide concentration係一個controlled variable in your experiment.
如果係咁嘅話，第一句寫法上好啲。 第二句可能會被人誤會你increase sodium hydrogencarbonate solution concentration，因此carbon dioxide amount increase。

係研究photosynthetic rate experimental set up 加sodium hydrogencarbonate solution 係 provide carbon dioxide for photosynthesis to occur 定係increase amount of carbon dioxide in water hence increase photosynthetic rate

邏輯d諗 你自己用字應有有唔同

兩個唔同情況

所以睇你實驗目的

Study effect of light intensity on photosynthetic rate of aquatic plant

Provide CO2

You are absolutely correct

你有野問咪係到問囉 我一樣答你

依啲過程洗唔洗背？
如果要考會點問？

每一步都關酶事

出得盡，想殺全港考生既，可以克雷伯c循環x酶既長答題

你可以準備下

要背
其實你可以查最新課程指引，好多問題你可以係入邊搵到官方答案

始終我地答呢類是否題，絕對無官方指引咁官方同正確

近年出得多唔多？

你可以自己睇睇
我幾肯定dse未出過克雷伯同卡爾文循環既長答題

因為呢種題目，可以完全符合hkeaa最理想出題要求
- 數據處理
- 實驗推論
即係你背都無用，教科書唔會教

Closure of stomata in hot dry and windy condition will lower the rate of transpiration and gas exchange in plant 岩唔岩

如果你覺得錯 可以分享點解你覺得錯

因為我諗緊如果有sunlight 但好大風好高温 咁佢會唔會做photosynthesis 如果做咁oxygen 點出去

因為我諗緊如果有sunlight 但好大風好高温 咁佢會唔會做photosynthesis 如果做咁oxygen 點出去

放心
一來,gas exchange can takes place not only in stomata but also lenticles and direct upper epidermis of leaf since waxy layer is not 100% impermeable to O2

二來，植物有一個機制叫photo-respiration 去解決high [O2] in body既情況

如果想拎個2 卷一卷二大約要啱幾多

因為我諗緊如果有sunlight 但好大風好高温 咁佢會唔會做photosynthesis 如果做咁oxygen 點出去

同埋理想係photosynthesis

但做photosynthesis 前都有相應條件，你大量失水dehydrate, 咁基本metabolism 都做唔到, not to say an extra photosynthesis

再者，你諗個問題與會否closure of stomata <> transpiration 無關

Closure of stomata 唔係depends on photosynthesis

如果想拎個2 卷一卷二大約要啱幾多

今年中六先第一年修 有咩topic一定要讀左先

唔洗
拎2唔洗溫書都會有，所以你可以準備oral

再者，你諗個問題與會否closure of stomata <> transpiration 無關

Closure of stomata 唔係depends on photosynthesis

Closure of stomata 唔係depends on light intensity wind and temperature 咩
Under high temperature and strong wind transpiration rate increases leading to excess loss of water so guard cell becomes flaccid to close stomata
Low light intensity will close stomata to reduce water loss
