GENERAL HISTOLOGY

Detailed explanation-1: -(A) The endomembrane system includes plasma membrane, ER, Golgi complex, Lysosomes and vacuoles. (B) ER helps in the transport of substances, synthesis of proteins, lipoproteins and glycogen. (C) Ribosomes are involved in protein synthesis. (D) Mitochondria help on oxidative phosphorylation and generation of ATP.

Detailed explanation-2: -Explanation: Statement 1 is correct. The rough endoplasmic reticulum (ER) contains ribosomes that are responsible for the manufacturing of proteins in the cells.

Detailed explanation-3: -Examples of organelles are the nucleus (a structure that contains the cell’s chromosomes and is where RNA is made), mitochondria (structures that make energy for the cell), and lysosomes (sac-like containers filled with enzymes that digest and help recycle molecules in the cell).

Detailed explanation-4: -Which statement best describes the organelles in a cell? Organelles must work together and their activities must be coordinated.

Detailed explanation-5: -Organelles are small structures within the cytoplasm that carry out functions necessary to maintain homeostasis in the cell. They are involved in many processes, for example energy production, building proteins and secretions, destroying toxins, and responding to external signals.
