Treating the common cold during pregnancy. Many of my pregnant patients inquire as to what medication they can use when they experience symptoms of the common cold, such as cough, congestion, sneezing, and fever. I am hesitant to recommend over-the-counter cold remedies because I have heard conflicting information regarding the safety of these products.
Gametophytes. The gametophyte is the dominant phase in the life cycle of moss plants. This is the form of the plant most people are familiar with since it is often seen carpeting trees, rocks, and parts of the forest floor. Photosynthesis takes place in the gametophyte phase.
The moss life-cycle starts with a haploid spore that germinates to produce a protonema (pl. protonemata), which is either a mass of thread-like filaments or thalloid (flat and thallus-like).otanically, mosses are non-vascular plants in the land plant division Bryophyta. They are small (a few centimeters tall) herbaceous (non-woody) plants that absorb water and nutrients mainly through their leaves and harvest carbon dioxide and sunlight to create food by photosynthesis.
