2 - Organisation of the Organism Flashcards
All living organisms are made up of
Cells
Common features of plant and animal cells
cell membranes, cytoplasm, nucleus with DNA
An electron microscope can magnify up to ____ times
500,000
An electron microscope makes these things visible
Ribosomes, mitochondria, chloroplasts, cell membranes, and more
Structures unique to plant cells
Cell wall, chloroplasts, large central vacuole
Animal cells are made up of
Nucleolus, Nucleus, Ribosomes, RER, SER, Golgi apparatus, Lysosomes, Mitochondria, Cell membrane, small impermanent vacuole, cytoplasm
Plant cells are made up of
Nucleolus, Nucleus, Ribosomes, RER, SER, Golgi apparatus, mitochondria, large permanent central vacuole, cytoplasm, chloroplasts, cellulose cell wall, cell membrane
Bacteria cells are made up of
Cell wall, cell membrane, cytoplasm, circular DNA (NO NUCLEUS), Plasmids, ribosomes, and the glycocalyx - they also have pilli, a sex pilus, and a flagellum
Levels of cell organisation
Organelle (like mitochondria), Cell, tissue, organ, organ system, organism
Tissue definition
Multiple cells which are similar in structure and carry out the same function
Types of tissue
Nervous tissue, muscular tissue, connective tissue (like blood and bone and cartilage), Epithelial tissue
Magnification formula
magnification = image size/actual size
