B1.1.1 Plant And Animal Cells Flashcards
Where is the genetic material stored in a eukaryotic cell
The nucleus
Size of eukaryotic cell?
Relatively large, 1um-100um
Where is the genetic material stored in a prokaryotic cell?
Floating in the cytoplasm
Size of prokaryotic cell?
1-10um
What subcellular structures are found within eukaryotic cells
Nucleus
Cell membrane
Cytoplasm
Mitochondria
Function of the nucleus
Controls activities of the cell
Contains cells genetic material ARRANGED AS CHROMOSOMES
Determines cells appearance and function
Contains instructions to make new cells/organisms
Function of mitochondria
Site of respiration
Enzymes enable glucose and oxygen to react together (contains enzymes for respiration)
The reactions transfer vital energy to the organism
Function of cell membrane
Selective barrier that controls which substances pass in and out of the cell
Protects and supports the cell
Contains receptor molecules
Function of cytoplasm
Jellylike substance
Site of chemical reactions which keep the cell alive
Example of eukaryotic cell
Plant and animal
Example of prokaryotic cell
Bacterial
What extra subcellular structures do plant cells containing proteins
Cell wall (cellulose)
Chloroplast
Vacuole
Function of the chloroplast
Contain chlorophyll that transfers the energy from the sun to the plant as light -used in photosynthesis
Are only in the Green parts of a plant
Function of cell wall
Surrounds the cell
Made of a tough fibre called cellulose which makes the wall rigid and supports the cell
Function of the vacuole
Contains cell sap
-Helping to keep the cell rigid
-Supporting the plant
-Keeping it upright
