Cells презентация

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

Prokaryotic vs. Eukaryotic
Examples:
Bacteria
Examples:
Plant cells
Animal cells
Fungi
Protists

Plasma Membrane
Plasma membrane
1. Surrounds Cells
2. Protected by cellulose and protein cell wall in
plants

Cytoplasm
Cytoplasm
1. Fluid (Cytosol) and organelles that make up
the inside of the cell

Nucleus
Nucleus
1. Membranous nuclear envelope
2. Chromosomes of DNA and protein (Histones)

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

Ribosomes
Ribosomes
1. Attached to Rough ER
2. Site of protein synthesis

Golgi Apparatus
Golgi Apparatus (Golgi body, Golgi complex)
1. Assembly and editing of proteins

Lysosomes
Lysosomes
1. Contain enzymes that break down and help
recycle large proteins in animal cells

Mitochondria
Mitochondria
1. Powerhouse ‑ site of ATP synthesis

Flagella and Cilia
Flagella and Cilia
1. Cell surface projections for movement

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
