Question
double membrane bound structure; contains DNA; a peroxisomes inner membrane folded to increase surface area; site of cellular respiration .smooth endoplasmic reticulum mitochondria - #1 membranous structure composed of network of tubules; involved in steroid hormone synthesis d. lysosomes membranous structure composed of network of evacuole flattened sacs; involved in protein processing: studded with ribosomes; continuous with nuclear.chloroplast envelope 8 rough endoplasmic reticulum membrane bound organelles containing many h. enzymes; break down cell waste into monomers for recycling golgi apparatus i. nucleus J. ribosomes # found in the cytoplasm; site of protein synthesis; contain subunits composed of protein and RNAExplanation / Answer
1-C mitochondria are the double membrane bound cell organelles containing DNA. They are the semiautonomous structures that are involved in aerobic respiration.
2- B smooth endoplasmic reticulum are the site of synthesis of lipids, vitamins and steroid hormones.
3-G rough endoplasmic reticulum contains ribosomes which are involved in the synthesis of proteins.
4- D lysosomes are the membrane bound organelles that contains many hydrolytic enzymes. These enzymes helps in intracellular digestion and cell autolysis (digestion of whole cell) during starvation.
5-J ribosomes are membrane less cell organelles that are composed of two subunits and are involved in protein synthesis. They are manufactured in nucleolus and consists of ribonucleoprotein.
