The nucleus contains the genetic material of the cell, deoxyribonucleic acid, or DNA, which is…. Mitochondria and chloroplasts have the ability to provide cellular energy and they contain their own DNA that encodes some of the own proteins. Organelles that perform photosynthesis in photosynthetic cells of plants and algae are called chloroplasts.
Chloroplasts have three major compartments; the first compartment is the space that is in between the two membranes that surrounds the chloroplast. The next compartment is a thick fluid within the chloroplast called the storma. Then finally suspended in the fluid is a network of membrane-enclosed disks and tubes.
The double membrane that protects the nucleus is similar to the thin single membrane made up of proteins and lipids. The membrane controls the passing of substances entering…. The mitochondria, which is a bilayer structure that generates adenine triphosphate ATP , a form of energy SparkNotes: Intracellular Components. Peroxisome is also included in the intracellular organelles. This is a single-membrane structure that is found in all eukaryotic cells and functions to break down fatty….
Secondary lysosomes digest extracellular material of which is engulfed into the cell by a process called endocytosis. A phagocytic vesicle is pinched off from the cell plasma membrane and encloses the material to be digested. This vesicle fuses with the lysosome to form a phagolysosome complex. The acidic environment denatures macromolecules to increase their surface area for hydrolases to act.
Once broken down, the soluble, useful material such as sugars, amino acids and nucleotides are used by the cell as nutrients; they enter the cytosol through the lysosomal membrane by either facilitated diffusion or active transport. Rough endoplasmic has a surface dotted with proteins and the smooth endoplasmic is made up of tubules which increases surface area.
They insure there is more surface area for cell reactions. Also involved in making nuclear membranes during the division of cells. Carbohydrates and proteins are transported to different organelles including lysosomes and plasma membrane. Golgi body- they are only found in eukaryotic cells.
