Air membantu biji benih memulakan perubahan untuk bercambah. Biji benih yang tidak mendapat air kekal kering dan tidak mula tumbuh.
Langkah 1
Biji benih memerlukan air
Air membantu biji benih memulakan perubahan untuk bercambah. Biji benih yang tidak mendapat air kekal kering dan tidak mula tumbuh.
Biji benih memerlukan air = 种子需要水 水帮助种子开始变化，种子吸水后会变软、胀大，然后发芽。没有水的种子一直干干的，不会开始生长。 例子：把绿豆泡在水里一个晚上，第二天绿豆变大了，再过一两天就冒出小芽。 注意：放在干罐子里的绿豆可以放很久都不发芽，因为缺水。
Biji benih memerlukan air = seeds need water Water helps a seed start changing. The seed soaks it up, softens, swells and then germinates. A seed without water stays dry and does not begin to grow. Example: Soak mung beans overnight; the next day they are bigger, and a tiny shoot appears a day or two later. Watch out: Dry beans kept in a jar can stay ungrown for months because they lack water.
Langkah 2
Biji benih memerlukan udara
Udara juga diperlukan semasa percambahan. Biji benih yang tenggelam sepenuhnya tanpa ruang udara mungkin tidak bercambah dengan baik.
biji benih + ruang udara → percambahan berlaku
Biji benih memerlukan udara = 种子需要空气 种子发芽时也需要空气。如果种子完全泡在水里、一点空气也没有，它可能长不好，甚至不发芽。 例子：一杯绿豆完全浸在满满的水里，另一盘绿豆放在湿棉花上，盘子里的发芽较好。 注意：水不是越多越好，太多水会把空气赶走。
Biji benih memerlukan udara = seeds need air Seeds also need air while germinating. A seed that is fully sunk in water with no air space may grow poorly or not sprout at all. Example: Beans fully covered in a cup of water sprout worse than beans on damp cotton in an open dish. Watch out: More water is not always better, because too much water pushes out the air.
Langkah 3
Suhu mesti sesuai
Biji benih memerlukan suhu yang sesuai, tidak terlalu panas atau terlalu sejuk. Air, udara dan suhu yang sesuai perlu hadir bersama supaya percambahan dapat berlaku.
air + udara + suhu sesuai → biji benih bercambah
Suhu mesti sesuai = 温度要合适 种子需要合适的温度，不能太热也不能太冷。水、空气和合适的温度三样要同时具备，种子才能发芽，少一样都不行。 例子：放进冰箱的湿绿豆不发芽，放在室温桌上的湿绿豆却发芽了。 注意：有水有空气还不够，温度不对也会失败。
Suhu mesti sesuai = the temperature must be suitable Seeds need a suitable temperature, not too hot and not too cold. Water, air and the right temperature must all be present together for germination; missing one is enough to stop it. Example: Damp beans in the fridge do not sprout, but damp beans on a kitchen table at room temperature do. Watch out: Water and air are not enough if the temperature is wrong.

Apakah tiga keperluan asas biji benih untuk bercambah?
Tiga keperluan asas = 三个基本需要 这题问种子发芽的三个基本需要。回想三个步骤，每一步讲一样。检查选项时，三样都要是发芽真正需要的，有一样不对就不选。 例子：做蛋糕需要面粉、蛋和糖，三样都要对，少一样或换成别的就做不成。 注意：有的选项看起来很“科学”，但和种子发芽没有关系。
Tiga keperluan asas = three basic needs This question asks for the three basic needs of a germinating seed. Recall what each of the three lesson steps covered, one need per step. All three items in a choice must be real needs; if even one is wrong, reject that choice. Example: A cake needs flour, eggs and sugar; swap one for something else and it fails. Watch out: Some choices sound scientific but have nothing to do with germination.

Biji benih diletakkan pada kapas kering. Apakah yang kurang?
Kapas kering = dry cotton Seeds are placed on dry cotton, and the question asks what is missing. The clue is the word kering, meaning dry. Go through the three basic needs one by one, find which one dry cotton lacks, then look for it among the choices. Example: A towel dried in the sun feels crisp because no moisture is left. Watch out: What a big plant needs is not exactly what a sprouting seed needs, so focus on germination.
