Answer:
A. The fern transitioned from gametophyte generation to sporophyte generation.
Explanation:
Ferns undergo an ALTERNATION of GENERATIONS in their reproductive life cycle. That is, they alternate between an incospicuous gametophytic stage and a dominant sporophytic stage. The sporophyte produces haploid spores, which germinates into the gametophyte plant called PROTHALLUS.
The gametophyte produces gametes (male and female) which fuse together to form the diploid zygote, which eventually develops into the SPOROPHYTE plant via mitosis. In this question, the brown dots from the underside of a fern's leaves that Maria collected are the spores.
When she places them in a pot, the spores germinated into gametophyte stage, then formed sporophyte, which is the small leaves she noticed growing from the pot. From this, it can be observed that the fern is transitioning from GAMETOPHYTE generation to SPOROPHYTE generation.
The major result of the inflammatory response is to infection or injury. Tissue level , inflammation is characterized by redness , swelling and itching which result from local immune , vascular and inflammatory cell responses .
Pathogen such as viruses, bacteria or fungi can causes of inflammation. External injuries like scrapes or damage through foreign objects effects of chemicals or radiation.The first and the earliest symptom of inflammation is silent phase which based on reaction of resident cells of the damaged tissue.
There are three main stages of inflammation which can vary from intensity or duration. such as Acute- swelling stage, sub acute- regenerative stage , regenerative stage, chronic- scar tissue maturation and remodeling stage.
