Cells

• What are cells considered to be in living organisms?

  Building blocks of living things
• How do cells relate to tissues and organs?

  Cells of the same type form tissues
• What is the role of systems in organisms?

  Systems are made up of organs
• What is the plasma membrane's function?

  Protects the cell and regulates entry
• How does the cytoplasm function within a cell?

  It is the site of chemical reactions
• What is the nucleus often compared to in a city analogy?

  Town hall
• What is the purpose of nuclear pores?

  Allow substances to enter and exit
• What is the nucleolus's primary function?

  Ribosome production
• How are ribosomes described in the context of protein synthesis?

  They are like little factories
• What type of ribosomes are found in eukaryotic cells?

  80S ribosomes
• What is the function of rough endoplasmic reticulum?

  Protein synthesis and processing
• What is the role of smooth endoplasmic reticulum?

  Lipid synthesis
• What do vesicles do in a cell?

  Transport substances around the cell
• How does the Golgi apparatus function?

  Modifies and packages proteins for transport
• What are lysosomes often referred to as?

  Rubbish collectors
• What do lysosomes contain to perform their function?

  Digestive enzymes
• What is the role of centrioles in a cell?

  Involved in cell division
• What is the primary function of mitochondria?

  Respiration and ATP production
• What is ATP's full name?

  Adenosine triphosphate
• How do ribosomes in mitochondria differ from those in the rest of the cell?

  Mitochondrial ribosomes are 70S
• What does the matrix in mitochondria contain?

  Jelly-like substance for reactions
• What are the main organelles in an animal cell and their functions?

  • Plasma membrane: Protects and regulates entry
  • Cytoplasm: Site of chemical reactions
  • Nucleus: Control center of the cell
  • Nucleolus: Produces ribosomes
  • Ribosomes: Synthesize proteins
  • Rough endoplasmic reticulum: Protein synthesis
  • Smooth endoplasmic reticulum: Lipid synthesis
  • Vesicles: Transport substances
  • Golgi apparatus: Modifies and packages proteins
  • Lysosomes: Digestive enzymes for waste
  • Centrioles: Involved in cell division
  • Mitochondria: Respiration and ATP production
• What should you be able to identify from electron micrographs?

  Cell organelles
• Describe the relationship between cells, tissues, organs, and systems.

  • Cells are the basic units of life
  • Similar cells form tissues
  • Different tissues combine to form organs
  • Organs work together in systems
  • Systems make up the entire organism
