Endocytosis is specific for larger substances which cannot cross plasma membrane by any other mean.

Pinocytosis and phagocytosis are forms of endocytosis. So, in both cases plasma membrane is involved.

Cytoplasm is the gelatinous liquid that fills the inside of a cell. It is composed of water, salts, and various organic molecules. Some intracellular organelles, such the nucleus and mitochondria, are enclosed by membranes that separate them from the cytoplasm.

Other three are single membrane bounded organelles. Ribosomes are non-membranous organelles found both in eukaryotic and prokaryotic cells. 

The ribosomes are attached to mRNA through smaller ribosomal sub-unit.In both prokaryotic and eukaryotic cells, the smaller and larger ribosomal subunits are attached to form a mature functional particle. This attachment is controlled by the presence of Mg2+.

Ribosomes in cytoplasm are 80S.Ribosomes in mitochondria and chloroplast are 70S.

Mechanical support (Both RER and SER)Synthesis of proteins (RER)Detoxification of drugs (SER)Transmission of impulses (SER)

Vesicles from SER combine with convex face to become the part of Golgi apparatus, then after processing of proteins and lipids inside Golgi apparatus (glycosylation), products are packed and budded off from concave (maturing) face of Golgi apparatus to form Golgi vesicles.

Vesicles that arise from SER fuse to form cisternae for Golgi apparatus.

Lysosome is rich in hydrolases that use water for breakdown of molecules.

Tay-Sach’s disease is a rare disorder passed from parents to child. It is caused by the absence of an enzyme that helps in breaking down of fatty substances. These fatty substances, called gangliosides, build up to toxic levels in the child's brain and affect the function of the nerve cells.

Mature RBCs lack nucleus and most organelles. 

Peroxisomes are approximately 0.5µm in diameter. 

The glyoxylate cycle allows plants to grow on acetate because the cycle by-passes the decarboxylation steps of the citric acid cycle. In plants, these reactions take place in organelles called glyoxysomes.

The name peroxisome was applied because this organelle is specifically involved in the formation and decomposition of H2O2 in the cell.

Outer and inner membranes in chloroplast are smooth.Outer membrane is smooth while inner forms invaginations (cristae) in mitochondria.

Mitochondria have double membrane structure in which inner membrane forms infoldings called cristae in mitochondrial matrix. These inner membranes contain particles called oxysomes or elementary particles or F1 particles which contain ATPase (enzyme), so they are involved in ATP synthesis via chemiosmosis. 

Endosymbiotic hypothesis deals with how cells evolved in terms of their specialization in function, where primitive cells took up other cells in a symbiotic relation and then start inheriting them in longer run; as a result organelles like mitochondria and chloroplast are formed. 

Vacuole, Lysosomes and Peroxisomes are bounded by a single membrane whereas ribosomes are not bounded by any membrane.

In cellular organelles ribosomes are smallest while nucleus is largest in size. Ribosomes are composed of rRNA and protein and in turn protein is composed of amino acids.

Flagella are absent because most of the plant cells are non-motile, lysosomes are absent because most cells do not show phagocytosis and they have structure analogous to centrioles.

Protection from osmotic lysis is the function of cell wall.In neuron and muscle cell, cell membrane conducts nerve impulse.

Most abundant components of plasma membrane are proteins. The chemical composition of plasma membrane is:Proteins = 60-80%Lipids = 20-40%Carbohydrates = Small amount

Transcription in nucleus, Glycosylation in Golgi apparatus, while oxidative phosphorylation is the function of mitochondria. Fermentation occurs in cytoplasm.

Amino acyl-tRNA is involved in the formation of initiation factor with smaller ribosomal subunit.For the attachment of smaller ribosomal subunit with mRNA, there is a role of rRNA.For the attachment of ribosome with RER there is role of ribosomal protein.

S stands for Svedberg unit for sedimentation rate of ribosomes.

Cisternae are found in endoplasmic reticulum, Golgi apparatus, lysosome, peroxisomes and Glyoxisomes. All these are single membranous organelles.

ER is network of channels that extends between nucleus and plasma membrane.

Endoplasmic reticulum is channels which cannot change their place.

Golgi apparatus is involved in cell secretions. So, cells having secretory function abundantly have Golgi apparatus.

Lysosomes are important for phagocytes. In WBCs, neutrophils and macrophages act as phagocytes.

Peroxisomes are presents in eukaryotic cells while absent in prokaryotic cells.

Others are involved in oxidation.

These are abundant in lipid rich seeds where convert lipids in carbohydrates for energy supply to germination of seedlings.

Vacuole has ability to develop turgor pressure.

Plastids are found in plant cells only.Bacteria are prokaryotic cells.Chromatin is found in nucleus or nucleoid.

Thylakoids are found in chloroplast.

Blue green algae are prokaryotes which do not have membrane bounded organelles.RBCs do not contain organelles except for cytoskeleton.

Chloroplast transforms light energy into chemical energy while mitochondria from chemical energy stored in organic compounds to ATP.

DNA and nucleus are required for replication.

Eukaryotic nucleus has linear DNA. All others have circular, except viruses that may have circular or linear DNA.

Bacterial cells usually do not have cytoplasmic organelles except for ribosomes which are found in all type of cells.

As prokaryotic cells do not have membrane bounded nucleus so DNA is submerged in a cytoplasmic region called nucleoid.

Ribosomes are chemically made of rRNA and proteins in both type of cells. Plasma membrane of a bacterial cell lacks sterol while found in eukaryotic cells. Similarly bacterial flagella are made of flagellin protein while eukaryotic flagella of tubulin protein.

Prokaryotic membranes do not contain sterols while found in eukaryotic membranes.
