(2) Green garlic grows in the open air with green leaves; Garlic seedlings grow in shade, the leaves are yellow, the garlic buried in the soil is white, and the exposed part is green. Therefore, it is speculated that this change should be related to light, so it is assumed that the formation of chlorophyll should be related to light.
(3)(4) According to the characteristics of the control experiment, the experimental scheme can be designed as follows: part of garlic is soaked in two porcelain plates filled with water, and the garlic in the two plates is the same in quantity and similar in size; Then put disk A in a bright place and disk B in a dark place; Observe the growth of two pots of garlic seedlings every day. The results showed that the leaves of one pot of garlic seedlings with light were green, and the leaves of another pot of garlic seedlings without light were yellow. The conclusion is that the formation of chlorophyll is related to light.
So the answer is:
(1) Is the formation of chlorophyll related to light?
(2) The formation of chlorophyll is related to light;
(3) Soak part of garlic in two porcelain plates A and B filled with water, with the same quantity and similar size; Then put disk A in a bright place and disk B in a dark place; Observing the growth of two pots of garlic seedlings every day, the results show that the leaves of one pot of garlic seedlings with light are green, and the leaves of one pot of garlic seedlings without light are yellow.
(4) The formation of chlorophyll is related to light.
