Bio 11 - Moss & Fern Quiz

Front 1

Vascular

Back 1

Having Xylem (pipes for water) and Pholem (conducts products for photosynthesis).

Ex. trees, flowers, bushes.

Front 2

Osmosis

Back 2

The net movement of water across a selectively permeable membrane.

Front 3

Gametophyte

Back 3

- Haploid multicellular adult stage in the alternation of generations.
- Heart shaped 5-6mm (prothallus).
- produce male & female gametes (N).
- rarely see it (ex. moss - dominant).
- Archegonia & Antheridia on underside

Front 4

Fragmentation

Back 4

- Asexual reproduction

Front 5

Prothallus

Back 5

Heart shaped part of Gametophyte, 5-6mm

Front 6

Non-vascular

Back 6

no xylem (piperes for water) or pholem (nutrients)

Front 7

Thallus

Back 7

leaf-like, sunlight and water absorption (via osmosis because thin leaves)

Front 8

Haploid (N)

Back 8

contains half the chromosomes needed to make up a zygote, to become diploid (2N)

Front 9

Gemma cups

Back 9

fall off and grow new individuals: asexual form of reproduction

Front 10

Zygote

Back 10

initial cell formed when two gamete cells are joined (2N)

Front 11

Xylem

Back 11

the BIG tubes - transport water and minerals

Front 12

Rhizome

Back 12

stem-like, often grows underground

Front 13

Diploid

Back 13

A cell or an organism consisting of two sets of chromosomes: usually, one set from the mother and another set from the father.

Front 14

Pinna

Back 14

leaflets that form frond (fern leaf)

Front 15

Annulus

Back 15

- ring or group of thick-walled cells around the sporangia of many ferns that functions in spore release.
- dry up, pull back, and release spores

Front 16

Pholem

Back 16

transports sugars made in leaves to rest of plant (small tubes)

Front 17

Rhizoid

Back 17

root-like, anchor to ground

Front 18

Archegonia

Back 18

gametophyte that produces female gametes

Front 19

Stomata

Back 19

Ferns - Openings for gas exchange (pore things)

Front 20

Alternation of generation

Back 20

the life cycle of ferns and mosses.

Front 21

Cuticle

Back 21

waxy layer that helps conserve water that moss don't have

Front 22

Sporophyte

Back 22

- adult stage (2N) - generation dominant in ferns (fronds)
- form from fertilized gametes

Front 23

Antheridia

Back 23

gametophytes that produce male gametes

Front 24

Sori

Back 24

sporangia clusters that form on underside of frond
