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.

gymnoseperms meaning "naked seeds" are a diverse group of seed plants and are paraphyletic. paraphyletic groups are those in which not all members are descendants of a single common ancestor. gymnoseperm seeds are not enclosed in an ovary; rather, they exposed in cones or modified leaves
 
        
             
        
        
        
Answer:
<u><em>Reproduction</em></u> of cells is one of the processes that help multicellular organisms maintain homeostasis.
Explanation:
In biology, homeostasis can be described as the capability of an organism to maintain its constant internal environment despite the changes in the external environment. 
External factors like pathogens in the environment tend to kill cells in our body like the skin cells and the immune cells. Through the process of cell division, our cells can reproduce and hence, maintain an equilibrium of the internal conditions. 
Reproduction of cells also causes growth. Hence, the process of reproduction of cells maintains homeostasis. 
 
        
             
        
        
        
Resistance stage of the general
adaptation syndrome (gas)
Resistance stage is the second
stage in which the body goes through series of changes while trying to resist
or adapt to the stressor. For the question given above, according to Hans Selye,
Katie is currently in the resistance stage of the general adaptation syndrome
(gas).
