Long protein extensions from cells used for movement

32
Q

Cilia

A

Microscopic protein structures to help an organism move.

33

A

Sexually produced reproductive body

34
Q

Conjugation Tube

A

Tube that allows gametes to move through and fuse with the other gamete

35
Q

Filament

A

Thread-like structure (Spirogyra has a filamentous shape)

36
Q

Colonial

A

Living as a colony. Volvox is an example of COLONIAL algae.

37
Q

Unicellular

A

Single-celled

38
Q

Syngamy/Fertilization

A

Process of the union of two gametes for the generation of a zygote

39
Q

Heterogamete

A

Gametes produced are different???? [BEST DEFINITION STILL UNCLEAR; WILL ASK TEACHER]

40
Q

Homogamete/Isogamete

A

Gametes produced are the same???? [BEST DEFINITION STILL UNCLEAR; WILL ASK TEACHER]

41

a maternal organ covering the moss sporophyte

44
Q

Seta/Stalk

A

Stalk supporting the capsule of a moss

45
Q

Protonema

a branched threadlike structure that grows from a (moss?) spore and eventually becomes the moss plant.

46
Q

Germination

A

To grow (seed or spore)

47
Q

Sori/Sorus

A

Tiny dots on the backside of a fern frond. Used for asexual reproduction.

Arc or a ring of specialized cells on the sporangium

53
Q

Stalk

A

Main stem of a (vascular) plant/gametophyte (?)

54
Q

Microgametophyte

A

Is what becomes of a microspore (pollen).

55
Q

Megagametophyte

A

Is what becomes of a megaspore (egg sack)

56
Q

Ovule

A

flower ovary/ovarian structure in angiosperms in which several ova (eggs) will develop

57
Q

Megaspore

A

The female gamete which develops into a megagametophyte. (this is the embryo sac in seed plants which contains the egg)
