TRANSCRIPT
Prokaryotic vs. Eukaryotic
• no nucleus• no membrane enclosed
organelles• single chromosome• no streaming in the cytoplasm• cell division without mitosis• simple flagella• smaller ribosomes• simple cytoskeleton• no cellulose in cell walls• no histone proteins
• nucleus• membrane enclosed organelle• chromosomes in pairs• streaming in the cytoplasm• cell division by mitosis• complex flagella• larger ribosomes• complex cytoskeleton• cellulose in cell walls• DNA bound to histone proteins
Plasma Membrane
Plasma membrane1. Surrounds Cells2. Protected by cellulose and protein cell wall in plants
Endoplasmic reticulum (ER)
Endoplasmic reticulum (ER)1. Rough ER - Transport of proteins (roughness is the attached ribosomes)2. Smooth ER – Processing and transport of lipids
Lysosomes
Lysosomes 1. Contain enzymes that break down and help recycle large proteins in animal cells
Microtubules and
Microfilaments
Microtubules and Microfilaments 1. Structural components of the cell
(cytoskeleton) in eukaryotes
Vacuoles
Vacuoles 1. Large central vacuoles in plant cells
contain enzymes and pigments in plant cells
Chloroplasts
Chloroplasts 1. Photosynthetic organelles in plant cells,
containing the chlorophyll pigments
