Cell membranes do not make nutrients (or energy) for the cells. This is the function of the mitochondria by the electron transport chain, tricarboxylic acid cycle, and beta oxidation. The cell membrane is responsible in holding the cytoplasmic components of the cells. The cell membrane is also involved in substance regulation by acting as a semi-permeable membrane for simple diffusion as well as the site where carrier proteins are embedded for facilitated diffusion (not ATP requiring) and active transport (ATP requiring). The cell membrane is also involved in cell to cell recognition because receptors are also embedded in the cell membrane.
Without frequent ground fires to clear out dead brush, a woodland becomes more susceptible to catastrophic wildfires and forest fires that can completely destroy the forest.
However, large forest fires are a natural phenomenon that occur less frequently than small ones.
Answer:
a. Gametophytes of bryophytes
d. Sporophytes of seedless vascular plants
Explanation:
Bryophytes are non-vascular plants. The plant body is haploid gametophyte which is its dominant phase and bears sex organs. The gametophyte may be leafy as in moss and may be with thalloid as in liverworts.
Pteridophytes are seedless, true vascular plants. The plant body is the diploid sporophyte. The sporophyte is differentiated into true leaves, stem and roots.
