Cell Organelle Structure Functions
Directions
- Go to http://tiny.cc/8b2bb
- Click on “plant cell”
- Scroll over each part of the plant cell and record in the column “What Does it do?”
- Put a check mark for each organelle found in a plant cell.
- Click on “animal cell”
- Scroll over each part of the animal cell and look for differences between the plant and animal cell.
- Record in the column “What does it do?”
- Put a check mark for each organelle found in an animal cell.
Organelle / What does it do? / Draw the organelle / In
Plant Cell? / In
Animal Cell?
1 / Cytoplasm / Material that surrounds other organelles, provides support and nutrients to the cell / X / X
2 / Centrioles
(Cytoskeleton) / Helps with cell division / X
3 / Chromosomes / Packages of DNA which contain information that is passed from parent to offspring / X / X
4 / Cell Membrane / The structure that forms a boundary between the cytoplasm in the cell and the outside of the cell / x / x
5 / Mitochondrion / Uses oxygen to process food molecules to make energy in the form of ATP. / x / X
6 / Nucleus / The structure that contains all the information a cell needs to function. (DNA) The information is sent to the ribosomes. / x / X
Organelle / What does it do? / Draw the organelle / In
Plant Cell? / In
Animal Cell?
7 / Endoplasmic
Reticulum / Processes materials it gets from ribosomes and uses them to modify proteins and makes parts of the cell membrane. / x / X
8 / Golgi Apparatus / Takes materials from the ER and finishes processing them. / x / x
9 / Lysosome / Holds chemicals which break down materials taken into the cell. Breaks down old cell parts. / x
10 / Central Vacuole / Stores water for support and other materials. Other vacuoles can transport materials into or out of a cell. / X / Contains
many small vacuoles.
11 / Chloroplast / Energy from sunlight is used to make high energy sugars. / X
12 / Cell Wall / The structure that forms the tough outer covering just outside the cell membrane. It supports and protects the cell. / X
13 / Vesicle / A structure that breaks off from the ER and transports materials made in the ER to the Golgi Apparatus. / X / x
14 / Ribosome / Structures on the ER and in the cytoplasm that use information from the nucleus (DNA) to make proteins. / x / x
Follow Up Questions:
- What is an organelle (in your own words)? A structure that has a specific function within a cell
- What organelles are found ONLY in PLANT cells? Cell Wall Chloroplast and Central Vacuole
- What organelles are found ONLY in ANIMAL cells? Centrioles and Lysosomes
- What organelles are found in BOTH plant and animal cells? Cell membrane. Mitochondrion, nucleus, endoplasmic reticulum, golgi apparatus, vesicle, ribosome
IN CLASS FOLLOW UP QUESTION (WE WILL DISCUSS THIS AS A CLASS!):
- Which organelle contains the directions for making proteins? Nucleus (contains DNA)
- Which organelle receives the directions for making proteins? Ribosome
- Once the protein is put together, which organelle modifies the protein by adding carboyhydrates and lipids? Endoplasmic reticulum (rough, not smooth)
- Which organelle packages proteins so they can begin working in the body? Golgi apparatus
- List the organelles required to make a protein (in the correct order):
Nucleus à Ribosomeà Endoplasmic reticulum à Golgi Apparatus
