Neighboring cardiac muscle cells in the walls of heart chambers have specialized cell-cell contacts that electrically and mechanically link the cells together, permitting the immediate passage of muscle impulses. What are these cell-cell contacts called?What is the body system that? a. ...
How does the functional relationship between the main organelles in a eukaryotic cell enable the cell to function? What are the functions of lysosomes in plant cells? Is the nucleolus a plant cell or a animal cell? Are ribosomes in the nucleus ? Which of the following is a fact supporting...
Some of the major cell organelles: 1.VacuolesVacuoles are substantially defined as repository bubbles of irregular shapes which are establish in cells. 2. Cell membraneThe cell membrane is also named a tube membrane or cytoplasmic membrane. 3. CentriolesThe centrosome organelle is made up of two...

They are also involved in energy storage, as well as relaying signals within cells and from the bloodstream to a cell's interior (Figure 2). Some cells also feature orderly arrangements of molecules called organelles. Similar to the rooms in a house, these structures are partitioned off from...
Organelles are elements inside a cell that possess a double plasma membrane like the one surrounding the cell as a whole. The more notoriousmembrane-bound organellesinclude: •Nucleus:This contains the cell's DNA. The nucleus is often excluded from discussions of "organelles" because of its sta...
Ribosomes are organelles responsible for protein synthesis, a process that every cell must undertake to ensure the survival of the organism, whatever its overall size, shape and function. Each ribosome consists of a large subunit and a small subunit, both of which include ribosomal RNA (rRNA) ...
What happens to cell organelles during mitosis? Organelles: The organelles within a cell are known as the ''little organs'' that help with maintenance and thriving aspects of the cell. The organelles are very important when it comes to the cells making energy, getting rid of wastes, and stor...
However, cells, cellular organelles, and even molecules like DNA and protein are much larger than single atoms.Biologists use the scanning electron microscope to study the detailed architecture of cell surfaces. It uses an electron beam to scan the surface of a cell or group of cells that have...
Organelles are small subcellular structures located in the cytoplasm of eukaryotic and prokaryotic cells, and in more complex eukaryotic cells, organelles are often enclosed by their own membrane. Each organelle performs a specialised function for that cell, much like an organ does for the body. ...
