science(biology organelles structure and function)

• Mitochondrion Description: bean-shaped, double membrane and inner membrane highly folded. Function: creates energy for the cell
• What is the description of the mitochondrion?

  bean-shaped, double membrane, inner membrane highly folded
• Description of Nucleus Structure

  membrane bound(by nucleur membrane), contains nuclear pores(holes in membrane)
• The nucleus holds genetic material, directs and controls all processes carried out by the cell.
• nucleolus's structure is a small, dark spot located inside the nucleus, and made of proteins and RNA
• The nucleolus's function is producing ribosomes which are involved in making proteins
• Chloroplast's structure is green organelles located only in plant cells, double membrane, and contains chlorophyll
• Vacuole's structure is a large sac-like structure which is larger in plant cells than animal cells.
• The vacuole's function is water storage.
• Cytoplasm(cytosol)'s structure is semi fluid like substance located throughout the cell
• The cytoplasm(cytosol)'s function is holding organelles in place.
• The cell membrane's structure is made of a lipid(fats) bilayer which surrounds cytoplasm
• The cell membrane's function is semi-permeable (lets some substances in while not others) and protects the cell from foreign substances.
• The endoplasmic reticulum's structure is flattened, membrane-enclosed tubes, continuous with the outer membrane of the nucleus
• The endoplasmic reticulum's function is transporting materials and helping with photo synthesis
• Golgi bodies structure is a series of flattened, membrane-enclosed disks
• Golgi bodies function is packaging vesicles with things like digestive enzymes and cellular waste
• The Vesicles structure is fluid-enclosed sac surrounded by a membrane
• Vesicles have various functions depending on what they contain such as moving molecules, secreting substances, digesting materials, or regulating the pressure in the cell.
• Lysosome structure is a type of vesicle(packaged by Golgi Bodies) that contains digestive chemicals. It is in animal cells only!
• Lysosomes' function is killing foreign material in cells and can also kill the cell(programmed cell death = apoptosis.
• The ribosome's structure is small, composed of RNA, and found along endoplasmic reticulum
• The ribosome's function is putting proteins together (involved in protein synthesis)
• Cytoskeleton structure is proteins called microtubules and microfilaments and embedded in cytoplasm
• The cytoskeleton's function is mostly to support of cells and holding organelles in place
• Cell wall's structure is tough and is the outer layer in only plant cells
• Cell wall's function is protection and prevents over-expansion of plant cells
