Plant Development III

Question 1

How do embryos develop in angiosperms?

Answer 1

Series of transeverse and longitudinal divisions
That establish

Axial and radial polarity

Question 2

What are used to study embryo development?

Answer 2

Mutants

Question 3

How are mutants useful for studying plant developments?

Answer 3

Mutants that produce seedlings lacking part of the plant body provide insight into genetic control over the embryonic development of plant organs

Question 4

How is polarity establish early in the angiosperm embryo zygote?

Answer 4

Asymmetric positioning of the vacuole and nucleus

Question 5

In angiosperms how is the polarity (w the nucleus and vacuole) transmitted to the multicellular embryo?

Answer 5

Asymmetric division

Question 6

What is the polarity maintes by at the 2 cell stage?

Answer 6

Auxin fluxes XX

Question 7

What type of development occurs in the embryo of angiosperms

Answer 7

Radial development

Question 8

Role of auxin in embryo development of angiosperms

Answer 8

• ## induces periclinal divisions that establish radial expansion of embryo
