Cells
Are eukaryotic cells smaller or larger than prokaryotic?
Larger
In eukaryotic cells, multiple liner chromosomes are generally in the form of
liner strands of chromatin
Function of Central Vacuole
maintaining turgor pressure for the cell and also stores some pigments and waste materials.
ribosomes
make proteins
Prokaryotic cells are characterized by having
no nucleus, DNA in unbound region called the nucleoid, no membrane bound organelles, and cytoplasm bound by the plasma membrane.
Where is the cell wall located in eukaryotic cells?
outside the cell membrane
What characteristics do prokaryotic cells and eukaryotic cells have in common?
plasma membrane, cytosol, chromosomes, and ribosomes.
plasma membrane
selective barrier that allows sufficient passage of oxygen, nutrients, and waste to service the volume of every cell
Describe a cell wall
slightly elastic cellulose
Are eukaryotic cells structurally more complex or structurally quite simple?
structurally more complex
chromosomes
carry genes
Prokaryotic cells cytoplasm is bounded by a
cell membrane
Plant cells contain
cell wall, central vacuole, and plastids
Leucoplasts
colorless plastids used for the storage of starch
Chloroplast
contain chlorophyll and carries out photosynthesis
Where do plastids occur in some plant cells?
cytoplasm
Central Vacuole
Fluid call cell sap
Domains of Prokaryotic Cells
Bacteria and Archaea
Bacterial cells generally have a cell wall composed of the
Carbohydrate Peptidoglycan
Most important Chromoplasts
Chloroplast
Eukaryotic cells are characterized by having
DNA in a nucleus that is bounded by a membranous nuclear envelope, Membrane bound organelles, Cytoplasm in the region between the plasma membrane and nucleus, and Eukaryotic cells are generally much larger than prokaryotic cells
3 examples of Membrane Bound Organelles in Eukaryotic Cells are
Mitochondria, Golgi apparatus, and endoplasmic reticulum.
Are there membrane bound organelles in prokaryotic cells?
No
Do prokaryotic cells have a nucleus?
No
What organelles are present in some plant cells?
Plastids
Two principle types of cell structures
Prokaryotic and Eukaryotic
Are prokaryotic cells larger or smaller than eukaryotic cells?
Smaller
Are prokaryotic cells structurally quite simple or structurally complex?
Structurally quite simple
cytosol
The main component of cytosol is water that assists chemical reactions within the cell.
Do eukaryotic cells have a cell wall?
Yes
Chromoplasts
are plastids which are colored due to the presence of pigments
In eukaryotic cells, in addition to the cell membrane
there are numerous internal membranes that compartmentalize the cell and form organelles.
