Cell :the unit of life Flashcards
what are the largest and second largest cell organelles.
Chloroplast is the largest and mitochondria is the second largest.
Why nucleus is not added in the cell organelles.
Because nucleus is the controlling centre of the cell.
Where
did the metabolic activites occur in cell.
Cytoplasm is the place where 75% metabolic activities occur.
Example of prokaryotes.
Bacteria, blue green algae(cyanobacteria) and mycoplasma/PPLO(pleural pneumonia like organism).
What does it mean by “well organised nucleus is absent”.
it means genetic material(DNA) is not enclosed by cell nuclear membrane.
Cells having membrane bounded nuclei are called.
Eukaryotic cells.
Prokaryotes have cell wall surrounding the cell membrane except in.
Mycoplasma/ PPLO(pleuro pneumonia like organism)
Bacterias having small circular(DNA) outside the genomic DNA are called.
Plasmids (not plastids)
Foldings of nuclear membrane are called.
Measosome
plant cell are much larger than animal cell because.
for adjustment of sap vacuole and plastids/chloroplast.
cytology is the study of.
study of structure and function of cell.
function of microvilli.
in intestinal cell for absorption of liquid food.
membrane of nucleus is also known as.
karyotheca
the most abundant organic substance is
protein
what is the smallest cell organelle in both plants and animals.
ribosome
most common shape in bacteria.
baccillus(rod like)
flagilla may/ may not present.
define glycocalyx, what are the two forms in which glycocalyx exist.
glycocalyx (glyco-sugar, calyx-layer)
the two forms are-
*thick and tuff called capsule
these forms are dangerous, smooth in touch and without surface structures.
*if it is loose sheet then it is called slime layer.
write four features of cell wall.
cell wall gives structure prevent the cell from bursting.
