Flowering Plants (Angiosperms)

Flashcards about Flowering Plants (Angiosperms)

What is Anthophyta?

Flowering plants are classified in this phylum.

How do flowering plants differ from gymnosperms?

The main difference is that the ovules are enclosed within an ovary, which later becomes a fruit.

What is the purpose of the fruit in flowering plants?

To protect the developing seeds and aid in their dispersal

Name some major food crops that are flowering plants.

Rice, wheat, corn, and barley.

Name some examples of monocots.

Grasses, orchids, irises, onions, lilies, and palms.

Name some examples of eudicots.

Oaks, roses, mustards, cacti, blueberries, and sunflowers.

What are the distinguishing features of monocots?

Flower parts usually occur in threes, leaves have parallel venation, and seeds have a single cotyledon.

What are the distinguishing features of eudicots?

Flower parts usually occur in fours or fives, leaves have netted venation, and seeds have two cotyledons.

What are the main parts of a flower involved in sexual reproduction?

Sepals, petals, stamens, and pistil.

Where does pollen form in the stamen?

The anther.

What are the parts of the pistil?

Stigma, style, and ovary.

What is the micropyle?

A small opening in the integument that permits passage of the pollen tube into the ovule.

What develops into a seed coat?

The integuments.

What are the purposes of a fruit?

To protect the developing seeds and aid in the dispersal of seeds

What is the scientific name of the magnolia family?

Magnoliaceae

What is the scientific name of the walnut family?

What is the scientific name of the pea family?

Fabaceae or Leguminosae

What is the scientific name of the sunflower family?

Asteraceae or Compositae

What is the scientific name of the grass family?

Poaceae or Gramineae

What is apomixis?

The production of seeds without the sexual process.

What is double fertilization?

A process in the flowering plant life cycle in which there are two fertilizations; one fertilization results in the formation of a zygote, whereas the second results in the formation of endosperm.
