Inside Cells
Flashcards do conjunto (21)
- 1ChromoplastsOnly found in plant cells. Holds all colours apart from green (it is held by the chloroplasts)
- 2LeucoplastsWhite/clear in appearance. Holds starch
- 3ProkaryoteSmall with no defined nucleus. No membrane bound organelles. Linear chromosomes. e.g. bacteria cells
- 4EukaryoteBig with a clearly defined nucleus. Membrane bound organelles. e.g. animal cells
- 5NucleusThe control centre of the cell. Contains DNA and RNA. Contained in the nuclear envelope. Found in EUKARYOTES (prokaryotes have a nuclear region)
- 6RibosomesFound in Cytosol and nucleolus. Creates Proteins.
- 7NucleolusFound in Nucleus. Contains Ribosomes and RNA (the DNA of how to create proteins)
- 8Nuclear envelopeEnvelopes the nucleus
- 9Nuclear PoresSmall holes in the nuclear envelope that allow certain substances to pass in and out of the nucleus
- 10MitochondriaCreates the energy for the cell. Is the site of cellular respiration and created ATP (energy) from nutrients.
- 11ChloroplastsCreates the energy for the cell. Is the site of cellular respiration and created ATP (energy) from nutrients.
- 12CytosolFluid component of the cell that holds within it the organelles
- 13CytoplasmMade up of the contents of the cell (but the nucleus?)
- 14TonoplastEnvelopes the Vacuole
- 15VacuolePlants - Large and permanent. Helps support cell's structure.
Animals - Small and temporary. Contains Nutrients for the cell - 16Golgi ComplexFlat membranous sacs that are where proteins are synthesized and then packaged, into vesicles, to be secreted out of the cells.
- 17Plasma MembraneA phospholipid Bi-layer (hydrophilic heads and hydrophobic tails) that envelopes the cell. Has carbohydrates and proteins embedded in it to assist in the selective transfer of substances in and out of the cell
- 18Cell wallRigid cellulose structure that is outside the plasma membrane in Plant cells. Prevents cell expansion.
- 19Endoplasmic ReticulumA network of membranous channels that act as pathways - links cell membrane with other organells. RER (embedded with ribosomes) and the SER (no ribosomes)
- 20CentriolesA pair of protein filament structures involved in the separation of chromosomes during cell division
- 21LysosomesVesicles that contain powerful enzymes which break down foreign material and excess substances
