November 12, 2015• Activity Title: Cell Structure and Function.• Challenge: How does the structure of a
cell contribute to its function?• Concepts/Vocabulary:
–Nucleus–Cell membrane–Mitochondrion
–Chloroplast–Vacuole–Cell wall
Cell Structure and Function:• Two main types of overall cell
structures:Eukaryotic Prokaryotic
• Larger, more complex• High level of internal
organization:– Contain many membrane
bound organelles• Have a nucleus• Ex: Plants, Animal, Fungi
• Very small, simple• Low level or internal
organization– Few to no membrane
bound organelles• No nucleus• Ex: Bacteria
Cell Structure and Function:Eukaryotic
Prokaryotic
Cell Structure and Function:• Organelles: –“Little Organ”–Structures within cells that carry out a
specific function. – Things inside cells that do a certain
job for the cell.
Cell Structure and Function:• Cell Membrane:–Function: Separates the inside of the
cell from other cells and/or the environment. Controls the movement of substances in and out of the cell. –Analogy: Cell membrane is the traffic
cop of the cell.
Cell Structure and Function:
Cell Structure and Function:• Nucleus:–Very obvious when looking at eukaryotic
cells.–Function: Controls cell activities.–Analogy: Nucleus is the “brain” of the cell.–Plural: Nuclei
Cell Structure and Function:
Cell Structure and Function:• Mitochondrion–Function: Breaks down nutrients to
release energy (cellular respiration)–Analogy: Power plant of the cell (gives
the cell energy)–Plural: Mitochondria
Cell Structure and Function:
Cell Structure and Function:• Chloroplast:–Function: Site of photosynthesis–Photosynthesis is where plants
combine carbon dioxide and water and create food and oxygen:
Cell Structure and Function:
Cell Structure and Function:
Cell Structure and Function:• Vacuole:–Large fluid filled space within a cell
that is surrounded by a membrane.–Function: Storage facility for cell and
helps maintain cell shape.
Cell Structure and Function:
Cell Structure and Function:• Cell Wall:–Surrounds the membrane of some
types of cells.–Not as flexible as cell membrane. –Function: Structural support and
protection.
Cell Structure and Function:
Cell Structure and Function:1. What are some common structures of a cell?2. What type of organism does not contain a nucleus?3. What do mitochondrion use to produce energy for a
cell?4. What do chloroplasts use to produce nutrients for
plant cells?5. Why is the nucleus an important part of most cells?6. Plant cells have chloroplast to carry out
photosynthesis. Do plant cells have mitochondria as well? Why or why not?
