Front 1

Sporophyte

Back 1

The diploid (2n) multicellular stage in the life cycle of plant or alga

Front 2

Sporangium

Back 2

The enclosure in which spores are formed

Front 3

Spore

Back 3

Unit of asexual survival (think of a diploid seed)

Front 4

Gametophyte

Back 4

The portion of a plant’s life in which it only has one pair of chromosomes

Front 5

Gametangia

Back 5

The organ of a protist in which gametes are produced

Front 6

Archegonium

Back 6

Organ containg the female reproductive organs (female version of antheridium)

Front 7

Antheridium

Back 7

Organ containing the male reproductive organs (male version of archegonium)

Front 8

Strobilus

Back 8

Structure present on many land species consisting of sporangia bearing structures densely aggregated along a stem

Front 9

Ovule

Back 9

In seed plants, the Ovule is the structure that produces female reproductive cells

Front 10

Pollen

Back 10

The male gamete (plant version of sperm)

Front 11

Seed

Back 11

An embryonic plant (the ripened ovule)

Front 12

Flower

Back 12

Found in angiosperms And is a mechanic for joining the sperm with the eggs

Front 13

Wood

Back 13

Secondary growth of an angiosperm or gymnosperms

Front 14

Pollination

Back 14

The process by which pollen is transferred to the female organs of a plant

Front 15

Pollen tube

Back 15

Part of the male gametophyte, acts as a conduit to transport male gamete cells from the pollen to the ovules

Front 16

Meiosis

Back 16

Production of gametes

Front 17

Zygote

Back 17

The result of two gametes (male and female) joining together

Front 18

Embryo

Back 18

A section in the seed or on the inside of the archegonium which will detach from it’s parent and become a new individual

Front 19

Rhizome

Back 19

A modified stem of a plant which is often found underground, sending out roots and shoots from its nodes

Front 20

Frond

Back 20

A fern’s large divided leaf

Front 21

Tracheid

Back 21

Elongated cells in the xylem that serve as transport for water and mineral salts

Heterospory

Back 23

The production of spores of two different sizes and sexes by sporophytes of land plants

Front 24

Ovary

Back 24

An ovum producing reproductive organs in the female part of the organism

Front 25

Stigma

Back 25

The receptive tip of a carpel (the end of the anthers)

Front 26

Anther

Back 26

found in the stamen, which is the male reproductive organ of a plant

Front 27

Fruit

Back 27

The fruit is the seed bearing structure in angiosperms (don’t have to look like actual fruit)

Front 28

When a female gametophyte joins with two male gametes

Front 29

Endosperm

Back 29

A tissue produced on the inside of the seeds in flowering plants

Front 30

Vessel element

Back 30

On of the cell types found in xylem. Typically found in angio sperms and are absent from most gymnosperms. There are the main feature of distinguishing hardwood (angiosperms) and siftwood (conifers)

Front 31

Sieve tubes

Back 31

Specialised type of elongated cell in the phloem tissue of flowering plants. The ends connect in order to create a sieve tube
