1 白色紫茉莉能进行光合作用吗?进行光合作用的基本条件需要有吸收、传递、转化光能的色素分子,而白色的紫茉莉质体不含色素,显然不能进行光合作用。如果不能进行光合作用,那么它是如何生存的呢?仔细阅读教材发现,白色枝条的叶子是白色的,但是枝条是存在于花斑色植株上的一种枝条,它的营养可以靠植物体统一调配供应,因此它是可以开花结果的。可是当接受花粉的枝条为白色时,所结种子(F_1)发育成的植株为白色,这种植株会因为缺乏营养而死亡。所以不存在白色植株,只存在白色枝条。
1 white Mirabilis can carry out photosynthesis? The basic conditions for photosynthesis need to have absorption, transmission, conversion of light energy pigment molecules, and white Mirabilis plastid without pigment, apparently can not carry out photosynthesis. If you can not carry out photosynthesis, then how does it survive? Carefully read the textbook found that the white branches of the leaves are white, but the branches are present in a plant on a piebald branch, its nutrition can rely on plant unity Provision of supplies, so it can bear fruit. However, when the pollen-bearing branches are white, the seed of the seed (F_1) is white, and the plant dies due to lack of nutrition. So there is no white plant, only white branches.
