Questions and Answers

Match the following organelles with their functions:

Mitochondria = Breaks down food to make energy Endoplasmic Reticulum = The internal delivery system of the cell, it makes lipids and packages the proteins to be released from the cell Chloroplast = Organelles found in plant cells, photosynthesis happens here Golgi bodies (complex) = Processes and transports proteins and materials from the endoplasmic reticulum into and out of the cell by forming a bubble/ vesicle

Match the following cell components with their descriptions:

Cell Wall = Surrounds plant cell, enables the plant to stand straight Ribosomes = Proteins are made here, every cell needs proteins to live Nucleus = Controls the cell's activities and contains DNA Lysosomes = Mostly found in animal cells, digest food particles, gets rid of wastes and protects the cell from foreign invaders

Match the following cell structures with their functions:

Cell membrane = Allows certain materials to pass into the cell and out Vacuole = Large sacs in plant cells store water in plants and in animal cells they are smaller Rough endoplasmic reticulum = The part of the cell covered in ribosomes found near the nucleus, it delivers proteins throughout the cell ATP = A substance which stores the energy released by mitochondria

Study Notes

Organelles and Their Functions

  • Mitochondria: Powerhouse of the cell; generates ATP through cellular respiration.
  • Ribosomes: Sites of protein synthesis, can be free-floating or attached to the endoplasmic reticulum.
  • Lysosomes: Contain digestive enzymes to break down waste materials and cellular debris.
  • Endoplasmic Reticulum (ER): Involved in protein and lipid synthesis; rough ER has ribosomes, smooth ER does not.

Cell Components and Their Descriptions

  • Cell Membrane: Semi-permeable barrier that regulates the entry and exit of substances.
  • Cytoplasm: Gel-like fluid that fills the cell; site for many metabolic processes.
  • Nucleus: Control center of the cell; contains genetic material (DNA) and regulates cellular activities.
  • Cytoskeleton: Network of protein filaments that provides structural support and aids in cell movement.

Cell Structures and Functions

  • Cell Wall: Rigid outer layer found in plant cells; provides structure and protection.
  • Chloroplasts: Organelles responsible for photosynthesis, converting sunlight into energy in plant cells.
  • Golgi Apparatus: Processes and packages proteins and lipids for secretion or use within the cell.

Primary Functions of Cell Components

  • Plasma Membrane: Maintains homeostasis by controlling the passage of ions and molecules in and out of the cell.
  • Nucleolus: Produces ribosomal RNA (rRNA) and assembles ribosomes from proteins and rRNA.
  • Peroxisomes: Contain enzymes for breaking down fatty acids and detoxifying harmful substances.

Additional Cell Structures

  • Centrioles: Involved in cell division; help organize the spindle fibers.
  • Vacuoles: Storage organelles primarily for water, nutrients, and waste products; larger in plant cells.
  • Vesicles: Small membrane-bound sacs that transport materials within the cell.

Summary of Functions

  • Organelle interactions maintain cellular health and function.
  • An understanding of organelles aids in comprehending cellular processes and systems.
