Land plants experience life cycle called the

Answer 2

Alternation of generations

Question 3

The Alternation of generates life cycle consists of

Answer 3

Two multicellular stages: Gametophyte + Sporophyte stage

Question 4

What happens in the Gametophyte stage?

Answer 4

Plant cells are haploid and gametes are produced

Question 5

What happens in the Sporophyte stage?

Answer 5

Plant cells are diploid, with a diploid zygote forming. Spores are also produced via meiosis

Question 6

Zygote develops from the

Answer 6

Tissues of the female parent

Question 7

What is Gametangia?

Answer 7

Production of gametes in multicellular organs

Question 8

What is the female gametangia called?

Answer 8

Archegonia

Question 9

The Archegonia produces

Answer 9

A single egg

Question 10

What is the male gametangia called?

Answer 10

Antheridia

Question 11

The Antheridia produces

Answer 11

Many sperm

Question 12

Bryophytes consist of

Answer 12

Mosses, liverworts + hornworts

Question 13

Bryophytes are dominated by which part of the life cycle?

Answer 13

Gametophytes

Question 14

Are Bryophytes vascular or avascular?

Answer 14

Avascular, lacking both xylem and phloem

Question 15

Bryophytes are in need of water so the

Answer 15

Sperm can swim to the egg for fertilization

Question 16

Bryophytes are the smallest + simplest

Answer 16

Sporophytes

Question 17

Ferns + Other Seedless Vascular Plants consist of

Answer 17

Club mosses + horsetails

Question 18

Like Bryophytes, Ferns are also in need of

Answer 18

Water for sperm to swim to egg

Question 19

What is the dominant stage for Ferns?

Answer 19

Sporophyte

Question 20

For Ferns, meiosis produces haploid spores which then grow into

Answer 20

Gametophytes

Question 21

What are Seeds?

Answer 21

Multicellular plant embryos packaged with a food supply in a protective coat

Question 22

Seeds have reduced gametophytes, so they depend entirely on

Answer 22

Sporophyte for food and protection

Question 23

Seeds + pollen grains display Heterospory, which is when

Answer 23

Megaspores produce female gametes and microspores produce male gametes

Question 24

An ovule is made of

Answer 24

Megasporangium, megaspore + protective tissue

Question 25

What is the Pollen?

Answer 25

Male gametophyte with two sperm nuclei

Question 26

Pollens have a

Answer 26

Waterproof coat

Question 27

Gymnosperms are

Answer 27

Naked seeds not enclosed in ovaries

Question 28

Gymnosperms are conifers consisting of

Answer 28

Pines, spruces, firs + redwoods

Question 29

Angiosperms are

Answer 29

Flowering plants

Question 30

The Flower of angiosperms consists of

Answer 30

Sepals, petals, stamens + carpels

Question 31

What is the Stamen?

Answer 31

Male reproductive structures

Question 32

What is the function of the Stamen?

Answer 32

Produce microspores in the anthers that develop into pollen grains

Question 33

What are the Carpels?

Answer 33

Female reproductive structures

Question 34

What is the function of the Carpel?

Answer 34

Produce megaspores and female gametophytes with eggs

Question 35

The fruit is the

Answer 35

Mature ovary of the plant

Question 36

The fruit is formed due to the

Answer 36

Thickening of the Ovary

Question 37

What is the function of the fruit?

Answer 37

Allows for seed dispersion of angiosperms

Question 38

Angiosperms can be divided into

Answer 38

• Monocots

- Eudicots

Question 39

What are monocots?

Answer 39

Angiosperms with:

• One cotyledon in the seed
• parallel leaf venation
• Flowering parts in multiples of threes

Question 40

What are examples of monocots?

Answer 40

Orchids, flowers, lilies

Question 41

What are eudicots?

Answer 41

Angiosperms with:

• Two cotyledons in the seed
• Net leaf venation
• Flowering parts in multiples of 4 or 5

Question 42

What are examples of eudicots?

Answer 42

Roses, peas, beans, oaks
