Chap. 30 - PP Flashcards
Chapter 30 deals with what type of plants?
Seed plants
The biggest group of seedless vascular plants:
ferns
The spermatophytes, also known as phanerogams or phenogamae, comprise those plants that produce seeds. They are a subset of the embryophytes or land plants.

sporophytes
You find a gymnosperm and angiosperm with reduced gametophytes and dominant sporophytes. What category of plants is this?
Seed plant
With seedless vascular plants, which is dominant: gametophyte or sporophyte?
Sporophyte
You find a non-vascular plant that resembles a moss. Which is more likely to be dominant–sporophyte or gametophytes?
Gametophyte
You find a gymnosperm. What type of plant will this be? Will it be sporophyte or gametophyte dominant?
Sporophyte dominant
What is “naked” seed?
gymnosperm
You find a tree with microscopic female gametophytes inside an ovulate cone. What type of plant is this? What is dominant–gametophyte or sporophyte?
Seed plants. Sporophyte dominant.
Gymnosperm.
You find a microscopic female gametophytes inside the flower. What type of seed plant is this?
Angiosperm (covered seed)
a plant that has flowers and produces seeds enclosed within a carpel. A large group and include herbaceous plants, shrubs, grasses, and most trees.
angiosperm
a plant that has seeds unprotected by an ovary or fruit. Include the conifers, cycads, and ginkgo.
Gymnosperms
The Uniqueness of Seeds
a. Seed contains the ___ (derived from female gametophyte) and is for dispersal
b. ___ contains the _ gametophyte.
c. Gametophytes in _ _ are never free-living
a. embryo
b. pollen, male
c. seed plants
When are gametophytes never free-living?
When they are present in seed plants
What contains the male gametophyte in seed plants?
pollen
For exam, recognize the cotyledons of a plant embryo.
Embryo - leaves
MONOCOTS DICOTS
The two primary groups of flowering plants
Monocots, dicots
Name of flowering plant with an embryo with one cotyledon
Monocot (flower parts in multiples of three)
Name of flowering plant with an embryo with two cotyledon
Dicot (flower parts in multiples of 4-5)
