BP 4th exam

Angiosperms (Flowering Plants)

The clade Angiospermae (previously Anthophyta or Magnoliophyta) which contains the flowering plants.

Peduncle 

The stalk of the flower.

 Concept: Receptacle Definition

 The swollen base of the flower where the peduncle produces a flower bud or cluster of buds, and where other parts of the flower grow in whorls.

Concept: Calyx Definition

The collective term for the sepals (the outermost whorl, often green and petal-like, which protects the rest of the flower when the bud is closed).

 Concept: Stamen Definition

 The male reproductive structure of the flower, consisting of the anther (produces pollen) and the filament (stalk supporting the anther).

Concept: Pistil/Carpel Definition

The female reproductive structure of the flower, consisting of the stigma (receives pollen), style (stalk connecting stigma to ovary), and ovary (contains ovules).

Concept: Monocotyledonae (Monocots) Definition

One of the two largest classes of Anthophyta, characterized by having one cotyledon in the seed.

Concept: Eudicotyledonae (Eudicots) DefinitionConcept: Eudicotyledonae (Eudicots) Definition

One of the two largest classes of Anthophyta, characterized by having two cotyledons in the seed.

Concept: Brassicaceae Definition:

The amaranth family, known for conspicuous, spike-like flower heads made up of small, unremarkable bisexual flowers.

Concept: Solanaceae Definition

The potato family, known for flowers with five fused petals and five prominent yellow anthers held together in a point at the center.

Question: The two largest classes of the phylum Anthophyta are the Monocotyledonae and the Gymnospermae.

False

Question: The sepals of a flower are collectively known as the corolla.

False

Question: The anther and filament together make up the stamen.

True

Question: Brassicaceae is heavily modified by artificial selection into vegetables such as broccoli, cabbage, and kale.

True

Question: The Solanaceae family is known for having fruits that are typically dry capsules or achenes.

False

Question: Beets and quinoa are notable members of the Brassicaceae family.
