Human Bio Chap 3
Cards in this deck (23)
- 1Human BioChapter 2 and 3
- 2Cell TheoryThe principle that all living organisms are made up of cells and materials produced by cells
- 3Cell MembraneThe outer boundary of the cell
- 4CytoplasmThe thick fluid that fills up a cell with structures are suspended in it
- 5OrganellesStructures suspended in the cytoplasm that carry out particular functions
- 6CytosolThe liquid part of cytoplasm - 75-90% water
- 7CytoskeletonInternal scaffolding of protein fibres within the cytoplasm
- 8InclusionsSubstances that aren't a part of the cell structure that are found in cytoplasm like haemoglobin is found in red blood cells and melanin in skin cells
- 9Golgi BodyFlattened, membranous bags stacked on top of each other.
- 10VesiclesPinched off from the edges of the Golgi body's membranes.
- 11MitochondriaThe powerhouse of cells, release energy for respiration
- 12NucleusControls and regulated the activities of the cell
- 13Nuclear MembraneA membrane that separates the nucleus of a cell from the cytoplasm
- 14Nuclear PoresGaps in the nuclear membrane
- 15NucleolusA structure within a cell's nucleus, composed mainly of RNA
- 16NucleoplasmThe DNA and nucleolus are suspended in jelly-like substance
- 17LysosomesBreaks down worn-out organelles and break down materials
- 18CentriolesInvolved in the reproduction of the cell
- 19Endoplasmic Reticulum (ER)Provides a surface for chemical reactions can occur. Channels between the paired membranes are used for storage or transport of materials
- 20Smooth vs RoughSmooth ER have no ribosomes
Rough ER have ribosomes attached - 21RibosomesVery small and spherical, most are attached to membranes. Amino acids are joined together at the ribosomes to make proteins
- 22Cilia and FlagellaCilia is like short hair and found in lots
Flagella is longer and not found a lot - 23—
