Cells And Tissue Flashcards
Structural units of all living things
Cell
Discovered and name the “Cell”
Robert hooke
Cell is the smallest living unit that cannot be seen through naked eye
Cell theory
Cell three main region
Nucleus
Cytoplasm
Plasma membrane
Carry out all chemical needed to sustain life
Cells and tissue
Control center of the cell that contains DNA
Nucleus
Three regions of nucleus
Nuclear membrane
Nucleolus
Chromatin
Barriers of the nucleus
Nuclear membrane
Site of ribosome production and partial assembly
Nucleolus
Composed of unwound DNA and protein used for making protein
Chromatin
Barriers for cell contents
Plasma membrane
2 types of semi permeable, double phospholipid layer
Hydrophobic
Hydrophilic
Water loving
Hydrophilic
Water fearing
Hydrophobic
Others material in plasma membrane
Protein
Cholesterol
Glycoprotein
Plasma membrane specialization
Microvilli
Membrane junction
Fingerlike projection that increase surface area for absorption
Microvilli
Impermeable, feak proof sheets
Tight junction
Anchoring that prevent cell from being separated
Desmosomes
Allow communication between cells to connexons that span the two cell membrane
Gap junction
