Zanzabum

Answer: b. they accept a hydrogen molecule

Explanation:

NAD +: Nicotinamide Adenine Dinucleotide- Coenzyme that assists biological reactions by absorbing hydrogen atoms removed from the substrate. Its reduced form NADH or NADH2 contains more energy, which can be used to generate ATP in later reactions. Other examples of coenzymes used in the energy metabolism: FAD (Flavin Adenine Dinucleotide) and its reduced form FADH2

Multicellular gametophytes are the product of spores from ____​
jolli1 [7]

Answer:

In bryophytes, the sporophyte is minute and dependent on the relatively prominent and nutritionally independent gametophyte for resources. The moss gametophyte looks like a miniature herb, with tiny leaf-like photosynthetic organs. The gametophyte generation begins as a dormant spore, which germinates under appropriate conditions to produce filamentous and branching protonemal tissues. These form multicellular bud-like structures, each of which develops into a leafy shoot. The mature gametophytes produce male and female sexual organs, the antheridia and archegonia, respectively. The gametophyte is often sexually distinct, and plants are either male or female.

Each antheridium has an outer layer that encloses and protects thousands of motile sperm, which swim through available external water layer to the egg. Fertilization at the base of the cylindrical archegonium produces a diploid zygote which develops into an unbranched sporophyte. The sporophyte consists of a thin stalk attached to the gametophyte, and a capsule that encloses the sporophytic meiotic cells.

In recent years, the mosses Physcomitrella patens and Funaria hygrometrica have emerged as attractive model systems for studying gene function in non-vascular plants because of the relative ease of molecular manipulation by homologous recombination. Mutants affecting gametophyte development have been isolated and their analysis should provide insights into the molecular basis of gametophyte development in mosses.
