Cells Flashcards
Eukaryotic cells:
- Animal and plant cells
* complex
Prokaryotic cells:
- bacteria cells
* smaller and simpler
Nucleus
Plant and Animal Cells
- contains genetic material
* controls activities of the cell
Cytoplasm
Plant, Animal and Bacterial Cells
- where the chemical reactions take place
* contains enzymes that control reactions
Cell membrane
Plant, Animal and Bacterial Cells
- holds the cell together
* controls what goes in and out
Mitochondria
Plant and Animal Cells
- reactions for respiration take place
* respiration transfers energy for the cell so it can work
Ribosomes
Plant, Animal and Bacterial Cells
• involves in translation of genetic material in the synthesis of proteins
Cell wall
Animal, Plant and Bacterial Cells
- made of cellulose
* supports the cell and strengthens it
Vacuole
Plant Cells
- contains cell sap
* maintains internal pressure to support the cell
Chloroplasts
Plant Cells
- where photosynthesis occurs
- makes food for the plants
- contains chlorophyll
Chromosomal DNA
Bacterial Cells
- controls the cell’s activities and replication
* floats free in the cytoplasm
Plasmid DNA
Bacterial Cells
- small loops of extra DNA
* contains genes for drug resistance and can be passed between bacteria
Flagellum
Bacterial Cells
- long hair like structure
- rotates to make bacterium move
- moves bacteria away from harmful substances (e.g. toxins) and towards beneficial things (e.g. nutrients and oxygen)
