Chapter 20 + 22 Test Review

  • Have a cuticle and stomata – help with retaining moisture

  • and the movement of O2 and CO2 in and out of the plant

  • Developed a vascular system to transport water and nutrients.

  • Have lignin in cells to help the plant grow upright.

  • Developed pollen grains and seeds – no water needed

  • for reproduction.

  • N – Gametophyte

  • 2N – Sporophyte

  • Haploid – Gametophyte

  • Diploid – Sporophyte

  • Fern frond – Sporophyte

  • Green moss – Gametophyte

  • Prothallus – Gametophyte

  • Antheridium - Gametophyte

4. A plant that has xylem and phloem to transport water

and nutrients throughout the plant.


5. Fronds have sori on their undersides

Sporangia in the sori form spores through meiosis

When the spores germinate, the protallus form

The archegonia produce egg cells

Water must be present so that the sperm can swim to

the archegonia.

Fertilization takes place in the archegonia

The embryo grows into a sporophyte.

The young sporophyte is dependent on the prothallus

For a little while until it can photosynthesize on its own.
