2.the cell theory was proposed by schlieden and schwann
3. non membrane cell organelles found in both prokaryotes and eukaryotes are ribosomes
4.smallest cell mycoplasma is 0.3 micro metre in length
5.animal cells is different from plant cells in having centrosomes
6. gas vacuoles are found in blue green algae and green and purple bacteria
7.endomembrane systems contain Golgi apparatus lysosomes vacuoles and endoplasmic reticulum
8.Golgi apparatus is composed of flattened sac called cisterns
9.lysosomes distributed in cytoplasm
10.lysosomes works in acidic medium
11. enzymes of lysosomes are synthesized by RER made by Golgi apparatus
12.stain used to observe mitochondria is Janus green
13. cytoplasmic ribosomes is 80s and organelles lysosomes is 70s
14. thylakoids are present in chloroplast
15.ribosomes 70s in prokaryotes discovered by George pakade ,made up of RNA and protein
16. double membrane system consist mitochondria chloroplast and nucleus
17.structure present inside the nucleus responsible for ribosomal unit formation is nucleolus
18. chromatin found in nucleus was discovered by Fleming
19. chromatin is essentially composed of DNA and histone
20.mitochondria is divided by fission ,Matrix possesses single circular DNA
21.microbodies are membrane bound minute vesicles found in plant and animals
22.animals cannot carry out gluconeogenesis as they do not poses glycoxylate enzyme
23.diagrammatic representation of karyotype of a species is called idiogram
24.membraneless RBCs are found in ribosome ,basal body ,centriole,nucleolus ,inclusion body etc.
25.microfilament provide support to plasma membrane involved in cyclosis helps in pseudo body formation
26.mitochondrial Matrix contain single circular DNA molecules and ribosomes outer membrane is permeable to monomers of Carbohydrates fats and proteins enzyme of electron transport are embedded in inner membrane
27. the shorter and longer arm of submetacentric chromosome are referred as P arm and q arm respectively
28.do not contain DNA -. lysosomes and vacuoles
29.nucleolus site for active ribosomal RNA synthesis
30.deplotene bivalents : lampbrush chromosome
31.allosomes : sex chromosomes
32.l-shaped chromosomes : submetacentric chromosome
33. salivary glands of insects : polytene chromosomes
34. function of Golgi body is cell wall formation ,secretion, formation of plasma membrane
35.middle lamella is present outside the primary wall
36.chief components of bacterial cell wall is amino acids and polysaccharides
37. the internal layer joining the primary wall of the two adjacent cell is called as middle lamella
38.the fluid part of cell known as cell SAP is non living components of vacuole of cell
39.a protoplast is a single wall less cell
40.endoplasmic reticulum Golgi apparatus nuclear membrane is absent in prokaryotes
41.centre of phosphorylation is called oxysome
42. fundamental characteristic of cell membrane is Ion regulation
43. the cell wall of plant cell are triple layered
44.plasma membrane's outer and inner layers are electron dense while middle layer is electron transparent
45.oxidative enzymes takes place mostly in mitochondria
46. Protein synthesis in a animal cell occurs in cytoplasm and mitochondria
47.transfer vesicles from RER fuse with cis region of Golgi complex
48. the main structure of centriole has nine triplets
49. cell wall in higher plants consists of cellulose and pectin
50.secretary and membrane proteins are processed in Golgi complex
51.cell wall are not present in mycoplasma ,gamate and amoeba
52.centrosome makes cytoskeleton
