2

Shared trait #2 between plants:
Also shared trait #2 between charophyceans and algae:

They are eukaryotic

3

Shared trait #3 between plants:
Also shared trait #3 between charophyceans and algae:

They are photosynthetic

4

Shared trait #4 between plants:
Also shared trait #4 between charophyceans and algae:

They have cell walls made of cellulose

5

Shared trait #1 between plants and charophyceans:

Rose shaped complexes

6

The rose-shaped complexes shared between plants and charophyceans are for __________ __________.

Cellulose synthesis

7

Shared trait #2 between plants and charophyceans:

Peroxisome enzymes

8

Shared trait #3 between plants and charophyceans:

Formation of phragomoplast

9

Female structure containing megasporangium, megaspore, and integument.

Ovules

10

Megaspores divide via __________.

Meiosis

11

Male structure containing microspore; transferred via wind or animals. Dispersal is water independent.

Pollen

12

A pollen grain contains _____ sperm each.

2

13

Seed plants evolved how long ago?

350MYA

14

Seed plants evolved in the __________ period.

Carboniferous

15

The two groups of seed plants are:

Gymnosperms and Angiosperms

16

Naked seeds.

Gymnosperms

17

Contained seeds.

Angiosperms

18

In __________, the ovule is not surrounded by ovary or fruit.

Gymnosperms

19

The 4 phyla of gymnosperms are:

Ginkophyta, Gnetophyta, Cycadophyta, and Coniferophyta

20

There is only one species in this phylum of gymnosperms.

Ginkophyta

21

Used in traditional medicine for circulatory disorders, memory enhancement, and dementia.

Ginkophyta

22

Most closely related to the angiosperm (according to classical views).

Gnetophyta

23

The only gymnosperm to exhibit "double fertilization". Not true double fertilization, because the second fertilization degenerates and does not form endosperm.

Gnetophyta

24

The gymnosperms known are cycads.

Cycadophyta

25

Gymnosperms dominant in the Mesozoic era.

Cycadophyta

26

Have crowns of stiff compound leaves with a short trunk.

Cycadophyta

27

Often mistaken as "palms", which are angiosperms.

Cycadophyta

28

Cycadophyta are __________.

Dioecious

29

Examples of this gymnosperm are pine and fir trees (most are evergreen).

Coniferophyta

30

This is the most species rich gymnosperm.

Coniferophyta

31

In __________, the ovule is surrounded by ovary or fruit.

Angiosperms

32

Flowers are made up of:

The stamen, the carpel, and the petal & sepal.

33

In flowers, the male pollen producing structure.

The stamen

34

The stamen is made up of two parts:

A filament and the anther

35

The __________ produces pollen.

Anther

36

In flowers, the female ovule producing structure.

The carpel

37

The carpel is made up of 3 parts:

The stigma, the style, and the ovary

38

Where pollen is deposited.

Stigma

39

Contains ovules.

Ovary

40

Attract pollinators.

Petals

41

During fertilization, pollen lands on the stigma, creating what?

A pollen tube along the style

42

Both sperms contained in each grain of pollen fertilize separate nuclei. This is called:

Double fertilization

43

One of the sperms fertilizes the __________, the other sperm fertilizes the __________ __________.

Egg, polar nuclei

44

When one sperm fertilizes an egg, that becomes the:

Embryo

45

When the other sperm fertilizes the polar nuclei, this becomes:

The endosperm

46

The __________ can be used for food.

Endosperm

47

Once an ovule is fertilized, the ovary matures into __________.

Fruit

48

Both dry and fleshy fruits are designed for dispersal by __________, __________, and __________.

Wind, water, animals
