In roots, the ‘‘hidden half’’ of al

In roots, the ‘‘hidden half’’ of all land plants,
gravity is an important signal that determines the direction
of growth in the soil. Hence, positive gravitropism has been
studied in detail. However, since the 19th century, the
response of roots toward unilateral light has also been
analyzed. Based on studies on white mustard (Sinapis alba)
seedlings, botanists have concluded that all roots are negatively
phototropic.

Dalam akar, '' tersembunyi setengah '' semua tanah tanaman,gravitasi adalah sinyal penting yang menentukan arahpertumbuhan di dalam tanah. Maka, gravitropism positif telahmempelajari secara mendetail. Namun, sejak abad ke-19,respon dari akar ke arah cahaya sepihak juga telahdianalisis. Berdasarkan studi tentang sawi putih (Sinapis alba)bibit, botanis telah menyimpulkan bahwa semua akar yang negatifphototropic.
