Question 1

Sporophyte

Answer 1

In the life cycle of plants with alternating generations. The asexual and usually diploid phase, producing spores from which the gametophyte arises. It is the dominant form in vascular plants. Ex the frond of a ferns.

Question 2

Bryophyte

Answer 2

Informal group consisting of three divisions if non vascular land plants, the liverworts, hornworts and mosses. Can survive in dryer conditions.

Question 3

Lychophytes

Answer 3

Tracheophyte subgroup of the kingdom plantae. One of the oldest lineages of extant vascular plants and contains extinct plants like baragwanthia that have been dated from the Silurian.

Question 4

Gametophytes

Answer 4

In the life cycle of plants with alternating generations. The gamete producing and usually haploid phase, producing the zygote from which the sporophyte arises. The dominant form in bryophytes

Question 5

Intermediate growth

Answer 5

Growth that is not terminated

Question 6

Determinate growth

Answer 6

Growth that stops once a genetically predetermined structure has completely formed.

Question 12

Ferns

Answer 12

Member of a group of vascular plants that reproduce via spores and have neither seeds nor flowers they differ from mosses by being vascular example having certain tissue that conducts water and nutrients and having branch to stems

Question 18

Apoplastic route

Answer 18

The space outside the plasma membrane within which material can freely defuse it is interrupted by the Kasparian strip and roots by air spaces between plant cells and by the plant cuticle
