Objectives ______________ the function of the cell nucleus ___________ the functions of the major cell organelles Describe Describe
Eukaryotic Cells Eukaryotic cells have _________ main structures: Cell Membrane Cytoplasm Nucleus 3
Cell Membrane _____________________ - the outer boundary double layer of phospholipids with proteins embedded. It is called a_______________ maintains homeostasis because it is selectively permeable. Cell Membrane Lipid bilayer
Cytoplasm ________________– gel surrounding the organelles Cytoplasm
The Nucleus Nucleus Control center DNA The nucleus is the ____________________ of the cell. The nucleus contains nearly all the cell's __________ Control center DNA
Ribosomes One of the most important jobs carried out in the cell is making ______________. Proteins are assembled on ____________________. proteins ribosomes
Endoplasmic Reticulum The ____________________ is the transportation center for proteins inside the cell. E.R.
2 ____ types of ER—rough and smooth. ______________ ER has ribosomes on its surface. Smooth ER _______________ have ribosomes on its surface. rough Does not
The Golgi Apparatus shipped modifies, sorts, and packages proteins proteins are then _____________ to their final destinations inside or outside the cell. shipped
Lysosomes lysosomes Clean up _____________________ filled with enzymes. The _________________ crew or the stomach of the cell. Lysosomes also break down organelles that have outlived their usefulness. Clean up
Mitochondria Mitochondria convert All eukaryotic cells contain ___________________. Mitochondria ___________________ the chemical energy stored in food into energy the cell can use. Mitochondria are the powerhouse of the cell. Mitochondria convert
Eukaryotic Cell Structures Animal Cell Smooth endoplasmic reticulum Nucleolus Nucleus Ribosome (free) Nuclear envelope Cell membrane Rough endoplasmic reticulum Ribosome (attached) Centrioles Golgi apparatus Mitochondrion
Plant cells have _____things animal cells do not: 3 Vacuoles: Chloroplasts Cell Walls
Vacuoles __________________ store materials such as water, salts, proteins, and carbohydrates. In many plant cells there is a single, large central vacuole filled with liquid. Vacuoles
Chloroplasts Chloroplasts Plants and some other organisms contain chloroplasts _________________________ capture energy from sunlight and convert it into chemical energy in a process called photosynthesis. Chloroplasts
Cell Wall Cell Wall _________________ is extra support for plant cells. Its outside the cell membrane. Provides protection and rigidity for the plant cell.
