Study Notes

Cell Structure and Function

  • All living things are composed of cells
  • The cell is the fundamental unit of life
  • Cells are produced from pre-existing cells

Cell Activities

  • Cells utilize energy
  • Cells store substances
  • Cells communicate with each other
  • Cells remove waste products
  • Cells transport materials
  • Cells reproduce

Cellular Respiration

  • Cellular respiration is a process that converts glucose into energy in the form of ATP
  • The output of this process is carbon dioxide, water, oxygen, and glucose

Animal Cell Structure

  • Cell Membrane: A semi-permeable barrier that controls what enters and exits the cell
  • Golgi Apparatus: Processes and packages proteins
  • Centrosome: Involved in cell division
  • Vacuole: Stores substances
  • Mitochondrion: Produces energy (ATP)
  • Nucleus: Contains DNA, controls cell activities
  • Smooth Endoplasmic Reticulum: Involved in lipid synthesis
  • Lysosome: Involved in waste breakdown
  • Cytoplasm: Gel-like substance where organelles are found
  • Rough Endoplasmic Reticulum: Involved in protein synthesis
  • Ribosome: Synthesize proteins
  • Nucleolus: Produces ribosomes
  • Nuclear Membrane: Double membrane surrounding the nucleus

Organelle Functions

  • Centrioles: Help in cell division
  • Cell Plasma Membrane: Regulates the transport of materials
  • Cytoplasm: Provides support for cell organelles
  • Golgi Apparatus: Modifies and packages proteins
  • Golgi Vesicles: Transport substances within the cell
  • Lysosomes: Break down waste
  • Mitochondria: Generate energy
  • Microtubules/Cytoskeleton: Maintain cell shape
  • Nucleolus: Produces ribosomes
  • Nucleus: Contains the genetic code
  • Pinocytotic Vesicle: Absorbs fluids
  • Ribosome: Synthesize proteins
  • Rough ER: Synthesize proteins
  • Smooth ER: Synthesize lipids

Plant Cell Structure

  • Cell Wall: Rigid outer layer providing support
  • Chloroplast: Site of photosynthesis
  • Cytoplasm: Gel-like substance
  • Endoplasmic Reticulum: Involved in various processes
  • Golgi Apparatus: Modifies and packages substances
  • Large Central Vacuole: Stores water and other substances
  • Mitochondria: Generate energy
  • Nucleus: Contains DNA
  • Nucleolus: Produces ribosomes
  • Ribosomes: Synthesize proteins
  • Vacuole: Storage of water and other substances

Plant vs. Animal Cells

  • Plant cells have a cell wall and a large central vacuole, while animal cells do not.
  • Plant cells have chloroplasts, while animal cells do not.
  • Other than the differences mentioned above plant and animal cells also have similar organelles.

Prokaryotic vs. Eukaryotic Cells

  • Prokaryotic cells are simpler, lacking a nucleus and membrane-bound organelles, while eukaryotic cells are more complex with a nucleus and other organelles
  • Both have cell membranes
  • Both have DNA or genetic material

Plant Cell Structure Description Continued

  • Amyloplast starch grain: Stores extra glucose
  • Cell membrane: Semi-permeable covering
  • Cell wall: Protects the cell, gives support
