Textbook Question
Chapter 41, Problem 9A
Loss-of-function mutations in the suspensor gene in Arabidopsis lead to the development of two embryos in a seed. After analyzing the expression of this gene in early wild-type embryos, you find high levels of mRNA transcribed from the suspensor gene in the developing suspensor cells. What is the likely function of the suspensor protein?
a. Suspensor protein likely stimulates development of the embryonic tissue.
b. Suspensor protein likely stimulates development of the suspensor tissue.
c. Suspensor protein likely inhibits embryonic development in the suspensor.
d. Suspensor protein likely inhibits suspensor development in the embryo.

Apart from food, plants need other nutrients like water and minerals.
Nitrogen, a mineral, is an important part of all living cells. All organisms need nitrogen in order to grow and repair.
Although nitrogen exists in its elemental form in the atmosphere, it cannot be directly used by plants.
7 Where else can plants obtain their nitrogen from?
Plants make their own nitrogen.
B Plants get it from animals.
Plants get it from the soil.
D
Plants have special structures to break down
atmospheric nitrogen.
