Question 1

Angiosperm:

1. what’s the definition?
2. what’s an example?

1.a flowering plant, which forms seeds inside a protective chamber called an ovary.
2.

Question 2

Carpels:

1. what’s the definition?
2. what’s an example?

Answer 2

1. the ovule-producing reproductive organ of a flower, consisting of the stigma, style, and ovary.
2. a flower.

Question 3

Double fertilization:

1. what’s the definition?
2. what’s an example?

Answer 3

1.a mechanism of fertilization in angiosperms in which two sperm cells unite with two cells in the female gametophyte (embryo sac) to form the zygote and endosperm.
2.

Question 4

Endosperm:

1. what’s the definition?
2. what’s an example?

Answer 4

1.in angiosperms, a nutrient-rich tissue formed but the Union of a sperm with two polar nuclei during double fertilization. It provides nourishment to the developing embryo in angiosperm seeds.
2.

Question 5

Eudicot:

1. what’s the definition?
2. what’s an example?

Answer 5

1.member of a class that contains the vast majority of flowering plants that have to embryonic seed leaves or cotyledons. 
2.

Question 6

Filament:

1. what’s the definition?
2. what’s an example?

Answer 6

1.in an angiosperm, the stalk portion of the stamen, the pollen-producing reproductive organ of a flower.
2.

Question 7

Fruit:

1. what’s the definition?
2. what’s an example?

Answer 7

1.a mature ovary of a flower. The fruit protects dormant seeds and often aids in their dispersal.
2.

Question 8

Gametophyte:

1. what’s the definition?
2. what’s an example?

Answer 8

1. in organisms that have alternations of generations, the multicellular haploid form that produces haploid gametes by mitosis. The haploid gametes unite and develop into sporophytes.
2. plants and some algae

Question 9

1. what’s the definition?
2. what’s an example?

Answer 9

1.

2.

Answer 11

1.

2.

Question 12

Monocot:

1. what’s the definition?
2. what’s an example?

Answer 12

1.member of a clade consisting of flowering plants that have one embryonic seed leaf or cotyledon.
2.

Question 13

Sporophyte:

1. what’s the definition?
2. what’s an example?

Answer 13

1. in organisms that have alternations of generations, the multicellular diploid form that results from the union of gametes. The sporophyte produces haploid spores by meiosis that develop into gametophytes.
2. plants and some algae.
