I believe in both groups , the sperm swim from antheridia to aronia. Both are tied to water by swimming sperm that require water to reach eggs. Neither of them has pollen, seeds, flowers, or fruits. Seedless vascular plants, however, have xylem and phloem, which bryophytes lack. For seedless vascular plants Cells in diploid sporophyte such as fern from undergo meiosis, releasing haploid spores that germinate and develop into gametophytes. Bryophytes reproduce sexually by forming sperm and egg cells within separate haploid male and female gametophytes.
Answer:
Organelles
Explanation:
Living cells of organisms contain structures within them that perform specific functions for the cell. These structures are called ORGANELLES. Organelles are organ-like structures that are specific about their function in a cell.
Both the cells of prokaryotes and eukaryotes possess organelles, however, the organelles in eukaryotes are bounded by a membrane e.g mitochondrion, chloroplast etc. while those of prokaryotic cells are not bounded by a membrane.
The organelles inside a cell can be seen with the aid of an electron microscope. Examples of organelles are chloroplast (functions in photosynthesis), mitochondria (functions in production and storage of cellular energy), ribosome (functions in protein synthesis) etc.
I believe it is gel electrophoresis.
Gel electrophoresis is a techniwue used to separate DNA fragments or other macromolecules such as RNA and proteins based on their size and charge. It can also determine the actual size of a piece of DNA by examining it next to a standard "yardstick" made up of DNA fragments of known sizes.
For each of the examples, simple diffusion, carrier, and channel mediated, each type involves the flow down a concentration gradient. This means that the molecules flow from an area of high concentration to an area of low concentration. In turn, this allows for a passive process, meaning no ATP is needed! I hope this explains your question.
