This is a vascular non-flowering plant that contains naked seeds that are not enclosed in chambers.

Gymnosperm

1

This is a vascular flowering plant that contains seeds that are enclosed in a chamber (fruit).

Angiosperm

2

This is an angiosperm structure that is specialized for sexual reproduction.

Flower

3

This is the base of the flower which serves as protection for the developing flower, is usually leaf-like and green in appearance.

Sepal

4

This structure is superior to the sepal, is generally colorful, has a sweet aroma and its function is to attract pollinators.

Petal

5

This is the female part of the flower with three main structures.

Carpel

6

This is the sticky structure center of the flower and is the part of the carpel that catches pollen released from the anther

Stigma

7

This is the slender neck that supports the stigma, it is a part of the carpel.

Style

8

This structure contains the ovules in the carpel.

Ovary

9

This is the male part of the flower with two main structures.

Stamen

10

This is the think stalk located in the stamen.

Filament

11

This is the terminal sack of the stamen.

Anther

12

The main function of the stamen is to produce ______ and ______.

Pollen grains and sperm

13

This type of flower contains all four organs; sepal, petal, stamen and carpel.

Complete flower

14

This type of flower does not contain all four organs.

Incomplete flower

15

This type of flower contain both the stamen and carpel.

Perfect flower

16

This type of flower only contain either the stamen or the carpel.

Imperfect flower

17

This type of flower contain floral organs that are roughly identical and occur at regular intervals around the center of the flower.

Radial symmetrical flower

18

This type of flower contains floral organs that do not occur at regular intervals around the center of the flower.

Bilateral symmetrical flower

19

This is another name for a single flower.

Solitary

20

These are groups of flowers packed tightly together.

Inflorescence

21

This color flower attracts birds.

Red

22

This color flower attracts bees.

Yellow

23

This color flower attracts moths.

White

24

This shape of flower provides a landing pad for butterflies.

27

A sporophyte is a _______ that produces spores.

Diploid

28

A gametophyte is a _______ that produces gametes.

Haploid

29

Multicellular tissue in which meiosis occurs and haploid spores develop.

Sporangium

30

This is a male gametophyte.

Pollen grain

31

Each stamen contains __ microsporangia.

4

32

This is the female gametophyte.

Embryo sac

33

This is the transfer of pollen from an anther to a stigma.

Pollination

34

Process in which water is absorbed and a pollen tube grows.

Germination

35

This is the union of two different sperm with different nuclei.

Double fertilization

36

This is the seed container that is derived from an ovary.

Fruit

37

This is the condition of extremely low metabolic resulting in the temporary suspension of growth and development.

Dormancy

38

This is the uptake of water due to low water potential of a dry seed.

Imbibition

39

Selective breeding for desired traits.

Traditional breed

40

Inserting target genes into an organism's genome.
