Title: Aim:%20What%20are%20the%20functions%20of%20cell%20organelles?


1
Aim What are the functions of cell organelles?
  • Ribosomes are responsible for assembling the
    proteins of the cell.

2
  • Ribosomes can be attached to the Endoplasmic
    Reticulum
  • Called rough ER

3
Endoplasmic Reticulum
  • The endoplasmic reticulum is an extensive network
    of membranes composed of both regions with
    ribosomes and regions without ribosomes.

4
Golgi Apparatus
  • responsible for manufacturing, warehousing and
    shipping certain cellular products, particularly
    those from the endoplasmic reticulum (ER).
  • A Golgi complex is composed of flat sacs that are
    stacked.

5
Lysosome
  • Lysosomes are membranous sacs of enzymes. These
    enzymes are typically hydrolytic and can digest
    cellular macromolecules (macro-).

8
ATP the energy bar
9
Centrioles function in cell division
  • Centrioles are cylindrical structures that are
    composed of groupings of microtubules arranged in
    a 9 3 pattern.

10
Plant cell differences
  • Cell wall
  • Large vacuoles
  • chloroplasts

The electron micrograph shows cells from a
sunflower leaf
11
Chloroplasts in the plant cell
  • A typical plant cell (e.g., in the palisade layer
    of a leaf) might contain as many as 50
    chloroplasts.

12
  • The overall chemical reaction involved in
    photosynthesis is 6CO2 6H2O ( light energy) ?
    C6H12O6 6O2
  • Summary
  • What is the relationship between respiration and
    photosynthesis?
