Summary Introduction
Introduction:
The leaves are the sugar source in plants and the sinks are the roots, young shoots and seeds. The sugar is delivered to these sinks through the phloem by a process called translocation.

cereal crops provide 60%
of the food energy taken in by
the world's human population.
Five cereal crops provide 60 percent of the food energy taken in by the world's human population. As shown in the image, these
cereals (grains) are rice, maize, wheat, millet, and sorghum. The portion of these crops consumed by humans is actually the seed
with its protective coverings from the fruit. These crops are
O bryophytes
O angiosperms
O fems
O gymnosperms
Phytochrome, plays an important role in flowering in many plants. It can also be used to determine when lettuce seeds germinate (shown in the figure below
What is phytochrome likely doing in the lettuce seeds?
Activating abscisic acid production
Activating inhibitors of germination
Inhibiting gibberellin synthesis
Turning on germination-related genes
