Inclusion bodies are nuclear or cytoplasmic aggregates which are stainable substances, usually proteins.
They are not involved in ingestion of food particles.
Golgi bodies are site of formation of glycoproteins and glycolipids in eukaryotic cells.
Rudolf Carl Virchow in 1858, gave the concept of Omnis cellula-e cellula regarding cell division.
This means that all cells arise from pre-existing cells by cell-division.
The enzymes required for the ETS are present in the inner matrix only as the elementary particles are embedded in the inner membrane of the mitochondrial matrix.
Lysosomes are not formed by the endoplasmic reticulum.
Instead, they are formed from vesicles that bud off from the Golgi apparatus.
Phospholipid synthesis does not take place in rough endoplasmic reticulum (RER).
Smooth endoplasmic reticulum (SER) is involved in lipid synthesis.
Pili and fimbriae are bacterial appendages which are not involved in locomotion.
Pili are long tubular outgrowths helpful in conjugation.
Fimbriae are small bristle-like fibres involved in attaching bacteria to solid surfaces.
Large central vacuole is the characteristic of plant cell, not animal cell which may have many small scattered vacuoles.
Lysosomes are small vesicles bounded by a single membrane and contain hydrolytic enzymes.
About 50 enzymes have been recorded to occur in them including acid phosphatases, sulphatases, proteases, peptidases, nucleases, lipases and carbohydrases.
Double Membrane bound Organelles: Mitochondria, Chloroplasts, Endoplasmic Reticulum, Golgi Body, and Nucleus.
Single Membrane bound Organelles: Lysosomes, Peroxisomes, and Vacuoles.
