‘Plant is a living thing. Plant needs ‘food’ to grow and stay healthy. This ‘food’ is call basic need.'
Keperluan asas bagi tumbuhan ialah air, udara (gas karbon dioksida) dan cahaya matahari.
‘Basic needs of plant are water, air (carbon dioxide gas) and sunlight.’
Tumbuhan mendapatkan air melalui akarnya dan mendapatkan udara dan cahaya matahari melalui bahagian daunnya.
'The plant gets the water via the roots, the plants get the air and the sunlight via it leaves.'
Apabila tumbuhan mendapat keperluan-keperluan asasnya yang mencukupi, maka tumbuhan itu boleh membesar dan hidup sihat, segar dan subur.
'When the plant gets the basic needs in the sufficient amount, so that the plant can grow and stay healthy.'
Video di bawah menunjukkan proses percambahan biji benih. Proses percambahan biji benih hanya memerlukan air dan udara (oksigen) sahaja. Dalam proses ini, bahagian akar akan tumbuh terlebih dahulu menuju ke sumber air (ransangan positf air) dan kemudian bahagian pucuk tumbuh menuju ke arah cahaya matahari (ransangan positif cahaya matahari).
'The following video shows about germination process of the seed. This process requires only water and air (oxigen gas). The roots appear initially and then followed by the shoots. The roots grow towards water source (stimulus - water positive) and the shoots grow towards sunlight source (stimulus - light positive).'
