Cell Structure + Organisation (1.2)
Eukaryotic
Membrane-bound organelles
Evolved from prokaryotic cells
DNA in nuclear membrane
Organelles not found in prokaryotic
Multicellular organisms
Fungi
Animals
Plants
Organelles
Nucleus
Double membrane
Envelope
Pores
Chromatin
Nucleolus
Protein synthesis
Mitochondria
Golgi body
Ribosome
Endoplasmic reticulum
Rough
Smooth
Centrioles
Prokaryotic
3.8 billion years ago
Similar structure to bacteria
Prokaryotic = No DNA in nuclear membrane
Unicellular
Virus
Non-living
Cannot reproduce on their own
Cannot respirate
Nucleic Acid
DNA
RNA
Tissues
Epithelial tissue
Squamous
Very thin
Reduces diffusion distance
Lines alveoli
Cuboidal
Same height + width
Columnar
Taller than wide
Found in small intestines
reabsorbs useful substances
Basement membrane
Stratified epithelium
Made from layers of cells
Bottom layer in contact with basement membrane
Top layers are dead
Found in skin + Oesophagus
Ciliated epithelium
Connective tissue
Loose connective
Fibrous connective
Bone tissue
Adipose tissue
Cartilage
Blood
Muscle
Cardiac
Unvoluntary
Does not rest
Striated
Smooth
Voluntary
Non-striated pattern
Skeletal
Voluntary
Fibrous
Striated
A group of cells carrying out the same function
Cells of multicellular organisms are organised
Cells > tissues
Tissues > Organs
Organs > Systems
Secretion and internal digestion
Exocytosis
Secretion of substances
Adds a new membrane to vesicle from inside
Increases surface area of plasma membrane
Endocytosis
Taking in substances
Infolding of the plasma membrane
Phagocytic vesicles
Removes membrane from plasma membrane
Decreases surface are of plasma membrane
