1 What is the plant body of the gametophyte generation in mosses known as?

A A true stem
B A thallus
C A rhizome
D A sporophyte

2 Do mosses have true roots, stems, and leaves?

A Yes

7 Due to their non-vascular nature, how do mosses absorb water?

A Only from the soil
B Directly from the soil and the air
C Only from the air
D Through specialized root hairs

8 What are spores in the moss life cycle?

A Sexual reproductive structures
B Asexual reproductive structures
C Structures for water absorption
D Structures for photosynthesis

9 Spores are formed by which generation of the moss life cycle?

A Gametophyte generation
B Sporophyte generation
C Both generations equally
D Neither generation

10 In what structure are spores formed within the sporophyte generation?

A A sporangium called the capsule
B A sporangium called the archegonium

A Air currents
B Wind
C Water
D Insects

12 What is the term for the structure that anchors the gametophyte to the substrate?

A Seta
B Foot
C Rhizoid
D Capsule

13 The 'foot' is part of which generation in the moss life cycle?

B It has no stems
C It lacks specialized conducting tissues like xylem and phloem
D It cannot reproduce

17 The sporophyte generation is responsible for producing which structures?

A Thallus
B Rhizoids
C Spores
D Sperm

18 What term describes the 'leaf-like structure' found on some moss gametophytes?

A True leaf
B Scale
C Appendage
D None of the above

19 Fertilisation in mosses requires the sperm to reach the ovum. This process is an example of dependency on what for reproduction?
