Plant Diversity II

Question 1

What is the two Vascular Seeded species

Answer 1

1. Gymnosperms

2. Angiosperms

Question 2

What is the Angiosperm closely related too?

Answer 2

Gymnosperm

Question 3

Are angiosperms and gymnosperms are Homospory or Heterospory?

Answer 3

They are Heterospory

Question 4

Are the Angiosperms and Gymnosperm, Sporophye dominant or Gametophyte dominant?

Answer 4

They are Sporophyte dominant

Question 5

During what ERA did the Gymnosperm diversify?

Answer 5

During the Mesozoic Era

Question 6

What is a factor that lead the Gymnosperms to success?

Answer 6

Pollen grains

Question 7

What do Pollen grains do?

Answer 7

THey are desiccation resistant, they consist of microgametophytes which caryy the male gametes of seed plants

Question 8

What is a pollen tube?

Answer 8

Its a tube that delivers sperm nucleus to the egg

Question 9

What happens in the pollen tube?

Answer 9

Embryonic sporophyte within the gametophyte tissues that are protected by previous sporophyte generation.

Question 10

Does the seed contain nutritive materials?

Answer 10

Yes

Question 11

In the alternation of generation of a Gymnosperm is the sporophyte large or the gametophyte?

Answer 11

The sporophyte is larger and longer lived. The gametophyte is tiny and depends on sporophyte for nutrition

Question 12

What is the only phylum under the Angiosperm?

Answer 12

Phylum Anthophyta

Question 13

WHat is a factor to the success of an angiosperm?

Answer 13

Pollinated by pollinators such as insects, birds and human.

Question 14

What advantage do plants pollinated by pollinators have?

Answer 14

It allows for distanced pollination, increasing genetic variation

Question 15

What is unique about the Angiosperm life cycle?

Answer 15

It contains double fertilization

Question 16

What dose the MALE part of a flower contain?

Answer 16

Fillament + Anther= Stamen

Question 17

What does the FEMALE part of a flower contain?

Answer 17

Ovary+ Style+ Stigma= Carpel/Pistil

Question 18

What is a Pedicel? (Angiosperm)

Answer 18

Stalk that supports the flower

Question 19

What is the Receptacle? (Angiosperm)

Answer 19

tip of the pedicel where the flower parts attatch

Question 20

What is the Sepal?

Answer 20

outer green, brown or colored that look like petals. They also protect the petals they are sometimes small and below the petals.

Question 21

What is a petal?

Answer 21

Colored, white, or even greenish whorl of bracts located just inside the sepals

Question 22

What is a Perianth?

Answer 22

It’s the Sepals+Petals together

Question 23

What does the Endosperm do?

Answer 23

It forms a nutritive tissue in the seed

Question 24

Where does the life cycle take place in an angiosperm?

Answer 24

It takes place in the Ovary of the Carpel of a flower

Question 25

How does the double fertilization occur?

Answer 25

Three sperm are produced, one fuses with one egg the other two fuse with the polar bodies which form the endosperm

Question 26

Angiosperms provide what percent of human calories?

Answer 26

80%

Question 27

What do Angiosperm provide?

Answer 27

Food- Potatoes, Mais, rice, wheat Beverages- coffee, tea Warm fire Aspirin- made from a tree

Question 28

What are some pollinators we discussed in class?

Answer 28

Bats, BIrds, bees, moths, wind

Question 29

Pollinators: Sepals and petals are reduced or not at all present; feathery or relatively large stigma; flower no odor, what's the pollinator?

Answer 29

WIND

Question 30

Sepals and/or petals Large, white or subdued (greenish or burgundy); distinct odor: Odor STRONG, HEAVY, SWEET (usually at night they give out the sweet scent)

Answer 30

MOTH

Question 31

Sepals and/or petals Large, white or subdued (greenish or burgundy); distinct odor: Odor STRONG, FERMENTING or FRUITLIKE; flower parts and pedicel STRONG (nucturnal flowers) what's the pollinator?

Answer 31
