21
Q

Tracheid

A

Thickened lignin-containing secondary cell wall
Pits in sides and ends of cell allow water to flow

22
Q

Vessel elements

A

Shorter and Wider than tracheid
gaps where both cell walls are missing

23
Q

Wood

A

made from Vessels and Tracheids

24
Q

Xylem collapse

A

Tensile force pushes conduit shut

25
Q

Cavitation

A

Air pulled in through pits causing conduit to fill with air

26
Q

Cavitation (cold temp)

A

Frozen water forms air bubbles that expand when thawed

27
Q

What does the Xylem rely on to pump water

A

Adhesive force or hydrogen bonds within water

28
Q

Adaptations for efficient plant reproduction

A

1) Sporopollenin
2) Gametes
3) Embryoe

29
Q

Sporopollenin

A

tough coat surrounding spores that resist drying

30
Q

Gametangia

A

Reproductive organs
protected gametes from drying and physical harm
in all land plants except angiosperm

31
Q

Antheridium

A

Sperm producing gametangia

32
Q

Archegonium

A

Egg producing gametangia

33
Q

Gametophyte

A

Haploid
gives rise to gametes
dominant in bryophytes

34
Q

Sporophyte

A

Diploid
Gives rise to spores unique to land plants

35
Q

Alternation of Generations (steps)

A

1) Sporophyte
2) Spores
3) Gametophyte
4) Fertilization
5) Diploid sporophyte

36
Q

Alternation of Generations: Sporophyte

A

makes haploid spores by meiosis

37
Q

Alternation of Generations: Spores

A

Germinate
develop into haploid gametes by mitosis

38
Q

Alternation of Generations: Gametophytes

A

Produce unicellular haploid gametes by mitosis

39
Q

Alternation of Generations: Fertilization

A

Two gametes unite from Diploid Zygote

40
Q

Alternation of Generations: Diploid Sporophyte

A

Developed from zygote division
Mitosis

41
Q

Zygote

A

Single cell - divide via mitosis + forms multicellular individual
Develop into sporophytes
Diploid
Result of fusion between two haploid cells (fermentation)

42
Q

Spores

A

Single cell - divide via mitosis + forms multicellular individual
Develop into gametophytes
Haploid
Result of meiosis inside sporangia

43
Q

Gametes

A

produced from mitosis inside gametangia

44
Q

Non vascular sporophyte

A

small and short lived
dependent on gametophyte for nutrition
Gametophyte-dominant life cycle

45
Q

Ferns and Vascular sporophyte

A

much larger and longer lived
Sporophyte-dominant life cycle

46
Q

Heterospory

A

production of two distinct spores by different strucutres
Microsporangia and Megasporangia
Gametophytes of seed plants are either male or female

47
Q

Microsporangia

A

produces microspores

48
Q

Microspores

A

Develop into male gametophytes and produce small gametes (sperm)

49
Q

Megasporangia

A

Produces megaspores

50
Q

Megaspores

A

develop into female gametophytes which produce large gametes (Eggs)

51
Q

Homosporous

A

Single type of spore produced
Spores develop into bisexual gametophyte (sperm + egg)
can self-fertilize and produce offspring
