Biolab: Kingdom Plantae - Spore-bearing plants

Question 1

Alternation of generations

Answer 1

A type of life cycle characteristic of plants and a few alga and fungi in which they spend half of their lives in multicellular [n] haploid phase (gametophyte), and part of their lives in a multicellular [2n] diploid phase (sporophyte).

Question 2

Gametophyte

Answer 2

Gametophytes form multicellular structures that produce male and female gametes.
-Gametophytes are produced from the mitotic division of spores
[Book] - The [n] haploid, gamete-producing stage in the life cycle of a plant.

Question 3

Sporophyte

Answer 3

The [2n] diploid generation of a plant or alga that has a double set of chromosomes.
-A sporophyte produces spores by meiosis. These spores develop into a gametophyte and both the spores and the gametophyte are [n] haploid.
[Book] - The [2n] diploid, spore-producing stage in the life cycle of a plant.

Question 4

Archegonium

Answer 4

The female reproductive structure that produces non-motile eggs.

Question 5

Antheridium

Answer 5

The male reproductive structure, which produces hundreds of small flagellated sperm that reach the archegonium by swimming.

Question 6

Spore

Answer 6

A reproductive cell that gives rise to individual offspring in plants, fungi, and certain algae and protozoa

Question 7

Vascular tissue

Answer 7

Vascular tissues are specialized for translocation of materials throughout the plant body (i.e., xylem and phloem)
-Ferns are true vascular plants, with xylem and phloem extending to all parts of the plant.

Question 8

Xylem

Answer 8

The vascular tissue that conducts water (and dissolved minerals and/or nutrients) in plants.

Question 9

Phloem

Answer 9

The vascular tissue that conducts dissolved sugar and other organic compounds in plants (i.e., the products of photosynthesis).

Question 10

Sorus

Answer 10

In ferns, a cluster of spore-producing sporangia

Question 11

Sporangium

Answer 11

A spore case, found in plants, certain protists, and fungi.
