(IB Biology) 2.3 Eukaryotic Cells
Size of eukaryotic ribosomes
80s
Similarities of the prokaryotic and eukaryotic cells
Both have a cell membrane Both contain ribosomes Both have DNA and cytoplasm
What is the cell wall in plant cells made up of?
Cellulose
Function of the nucleolus
Contains DNA
Function of the rough ER
Contains ribosomes, which are important for protein synthesis
Function of the nucleus
Controls cell activities and mitosis
What is the cell membrane in animal cells made up of?
Glycoproteins secreted from the cells
Function of the lysosome
Hydrolysis Digestion Breakdown of molecules
Function of cellulose in plant cells
Maintains the cell's shape Prevents too much water uptake Serves as a barrier against pathogens
Difference of plant/animal cells: Shape
Plant: Have a fixed, regular shape Animal: Have an amoebic shape
Difference of plant/animal cells: Vacuole
Plant: Have a large vacuole Animal: Have small vacuole
Difference of plant/animal cells: Structure
Plant: Have cell wall Animal: Do not have cell wall
Difference of plant/animal cells: Chloroplast
Plant: Have chloroplast Animal: Do not have chloroplast
Difference of prokaryotic/eukaryotic cells: Ribosomes
Prokaryotes: 70s Eukaryotes: 80s
Difference of prokaryotic/eukaryotic cells: Reproduction
Prokaryotes: Binary fission Eukaryotes: Mitosis/Meioisis
Difference of prokaryotic/eukaryotic cells: DNA
Prokaryotes: DNA is naked, circular, found in nucleoid Eukaryotes: DNA is enclosed, linear, found in neuclus
Difference of prokaryotic/eukaryotic cells: Structure
Prokaryotes: No membrane-bound organelles Eukaryotes: Have membrane-bound organelles
Difference of prokaryotic/eukaryotic cells: Size
Prokaryotes: Small Eukaryotes: Large
Function of glycoproteins in animal cells
Provides support for the cells Separates the tissues from one another
Function of the golgi apparatus
Sorting, storing and modification of products
Smooth ER
Synthesis and transport of lipids
Function of the endoplasmic reticulum
Transport of materials between organelles
