Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When mosses and ferns reproduce, what do they produce in the first cycle?
A
spores
B
fronds
C
sperm
D
egg
Explanation: 

Detailed explanation-1: -Fungi, moss and fern all three reproduce by a common method of asexual reproduction which is called spore formation. Spore formation occurs in non-flowering plants. Spore are minute structures that are produced by the parent plant and are released into the air.

Detailed explanation-2: -Spores. Spores are small reproductive structures that are released from the sporangium.

Detailed explanation-3: -In higher plants like ferns and fern allies, the sporophyte stage is dominant. Gametophytes produce gametes (sperm and eggs) in a special structure called a gametangium (-ia), while sporophytes produce spores in a special structure called a sporangium (-ia).

Detailed explanation-4: -As the embryo grows and develops into a mature diploid plant the prothallus dies. This mature plant is called the sporophyte generation since it produces spores. The sporophyte plant is the one most commonly recognized as a fern. The sporophyte then produces new spores as described above.

Detailed explanation-5: -Plants such as ferns and mosses are called nonflowering plants and produce spores instead of seeds. There is also another group called the Fungi, that include mushrooms, and these also reproduce by spores.
