Meiosis in SVPs creates:
diploid spores that turn into gametophytes
The generation that produces gametes in SVPs is:
n, gametophytes
Which generation shows the haploid and diploid number of chromosomes?
Gametophyte shows haploid, sporophyte shows diploid
The generation that produces spores is:
Diploid
Which generation is dominant is mosses?
The gametophyte/diploid stage
A moss zygote develops within the ____ and is dependent on the ____ generation:
Archegonia, haploid
What is the dominant generation in ferns?
Diploid
The heart-shaped gametophyte is ferns is the:
Prothallium
What protects the growing root?
The root cap
What area of the root is undergoing mitosis?
The Zone of Cell Division (the apical meristem)
What types of growth results in the elongation and diameter of a plant?
Elongation-apical meristems, diameter-lateral meristems
The ____ produces the xylem and phloem during secondary growth
Vascular cambium
The _____ produces the cork cells found in the outer bark
Cork cambium
The conifer tree is the ____ generation
Sporophyte
What generation is dominant in angiosperms?
Sporophyte
In what structure does double fertilization occur?
The pistil
What is double fertilization?
Two sperm are released into the pistil, one fertilizes the egg, the other fuses with 2 polar nuclei to make triploid endosperm (lunch)
What do ovaries and ovules turn into after fertilization?
Ovaries turn into fruit and ovules turn into seeds
Female parts of a flower:
The ovary contains the ovule, the ovary is connected by a style to the stigma which receives pollen, the stigma and style together are known as the pistil
Male parts of a flower:
The stamen consists of the stalk-like filament and the anther at the tip, where pollen is produced
What are the three parts of a seed?
The embryo (baby), seed coat (box), endosperm (lunch)
What term is used to describe the embryonic leaves?
Cotyledons
The radicle in a seed embryo will develop into____
Roots
The upper portion of the embryo is the ____ which will turn into the first true leaves and the shoot apical meristem
Plumule
