Plants are eukaryotic, autotrophic organism with differentiation
into stem, root and leaf. The branch of science that deals with the study of
plants is called botany.
Yeast (Saccharomyces
cerevisiae) is a fungus belongs to the phylum Ascomycota. Yeast is an unicellular eukaryotic,
heterotrophic organism without differentiated plant body. It is a widely
studied model organism for understanding the eukaryotic cell structure and
function.
Plant cell
|
Yeast cell
|
Generally
multicellular eukaryotic organism
|
Yeast
is unicellular eukaryotic organism
|
Cell wall is made up of cellulose
|
Cell wall is primarily made up of polysaccharides glucans and mannan and
small amount of chitin
|
Plant
cell possess chloroplast therefore carrying out photosynthesis (autotrophs)
|
Chloroplast
is absent in yeast cells therefore mostly living as saprophytes (feeding on
dead decayed matter) or as parasites (heterotrophs)
|
In
plant cells, phytosterols are associated with plasma membrane and membranes
of other organelles
|
In yeast
cells, ergosterol is the most common sterol associated with plasma membrane
and membranes of other organelles
|
In
plant cell, starch granules are present as stored food is starch
|
In yeast
cells, glycogen granules are present as stored food is glycogen
|
Individual
cells generally reproduce by mitosis as each cell is a part of multicellular
organism
|
Yeast
reproduce by binary fission or budding
