Match the description with the appropriate term. Where more than one answer may be correct, choose the best answer (most specific answer, if appropriate, or most general correct answer if the description can refer to multiple terms):

A.

An egg

A gametophyte

A sporophyte

An archegonium

An antheridium

A gametangium

A sporangium

A spore

1. A diploid plant (a multicellular, diploid organism or individual)

2. A haploid plant (a multicellular, diploid organism or individual)

3. A plant that produces spores

4. A plant that produces gametes

5. An organ or structure on a gametophyte in which gametes are produced

6. An organ or structure on a gametophyte in which eggs are produced

7. An organ or structure on a gametophyte in which sperm are produced

8. A single cell that, if fertilized, becomes a zygote

9. The multicellular structure in which a zygote forms in land plants

10. The structure in land plants in which an embryo begins to grow

11. An organ or structure on a plant in which meiosis occurs

12. An organ or structure on a plant in which spores are produced

13. A single haploid plant cell that has sporopollenin in its wall

14. A single haploid cell that divides to form a gametophyte

Solution

Sporophyte (2n): Diploid, multicellular form of a plant. It forms haploid spores through meiosis.

Gametophyte (n): Haploid, multicellular form of a plant. It forms gametes through mitosis.

1. ANS: A sporophyte (It is in diploid, but its spores are haploid).

2. ANS: A gametophyte

3. ANS: A sporophyte

4. ANS: A gametophyte

5. ANS: A gametangium

6. ANS: An archegonium

7. ANS: antheridium

8. ANS: antheridium

9. ANS: gametophyte

10. ANS: Egg (After fertilization it divides and forms embryo).

11. ANS: A sporophyte (in spores it occur)

12. ANS: A sporangium (spores are produced when sporangium splits).

13. ANS: Spores (Spores are covered by a polymer called sporopollenin).

14. ANS: Spore (Through mitosis spores can produce gametes).
