Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
True or false:The gametophyte generation makes eggs and sperm
A
TRUE
B
FALSE
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -However, mitotic division still follows meiosis in the sporophyte, resulting in a multicellular gametophyte, which produces eggs or sperm.

Detailed explanation-2: -The sexual phase, called the gametophyte generation, produces gametes, or sex cells, and the asexual phase, or sporophyte generation, produces spores asexually. In terms of chromosomes, the gametophyte is haploid (has a single set of chromosomes), and the sporophyte is diploid (has a double set).

Detailed explanation-3: –in vascular plants, the gametophyte is the dominant form of the plant: this is FALSE. In vascular plants, the sporophyte is the dominant form of the plant. Therefore, the answer is: in vascular plants, the gametophyte is the dominant form of the plant.

Detailed explanation-4: -The sporophyte produces spores by meiosis. The spores grow into gametophytes. The gametophytes produce gametes (eggs and sperm).
