Cell Membrane Structure Function Flexible boundary that surrounds the cell Bi-layer of proteins & phospholipids Selectively permeable: Regulates what enters & leaves the cell “border” Back to Animal Cell Back to Plant Cell

Smooth Endoplasmic Reticulum (S.E.R.) Structure Function Vesicles NOT covered with ribosomes synthesis of lipids and protein. transports large molecules around the cell Back to Animal Cell Back to Plant Cell

Lysosome Spherical body in the cytoplasm found in animal cells Function Structure Spherical body in the cytoplasm found in animal cells Storage of digestive enzymes (for digesting food or worn out cell parts) “recycling truck” Back to Animal Cell Back to Plant Cell

Cytoplasm Structure Function Made up of the cytosol (jelly/liquid within the cell) and all of the organelles Site of glycolysis (breaking down glucose molecules) Back to Animal Cell Back to Plant Cell

Chromatin “Unwound” chromosomes (DNA) Structure Function “Unwound” chromosomes (DNA) Instructions (genetic code) for producing all of the body’s proteins Back to Animal Cell Back to Plant Cell

Cytoskeleton A network of microtubules and microfilaments Structure Function A network of microtubules and microfilaments Support and aid in transport within the cell Back to Animal Cell Back to Plant Cell

CELLS Unit 2 Chapter 7

Principles of Cell Theory Unit of life All living things are made of cells All cells come from cells (no spontaneous generation)

Cells unicellular Multicellular

cells Many types Different functions

Cell Size <iframe width="560" height="315" src="//www.youtube.com/embed/t4Tst9DZFPI" frameborder="0" allowfullscreen></iframe>

All Cells Have: Membrane around cytoplasm Cytoplasm – thick fluid with organelles DNA

Organelles Cellular “organs” made of macromolecules

Cell Types Prokaryotic: bacteria Eukaryotic: plants, animals

Prokaryotic Cells NO nucleus Organelles have no membranes First cell type on Earth Smaller than eukaryotic cells bacteria

Eukaryotic Cells HAS a nucleus Possess many organelles with membranes Plants, Animals, fungi, protozoans Protozoan

Eukaryotic vs. prokaryotic cells

Eukaryotic cells Plant vs animal cells ribosomes

Cell Coloring Instructions: Use the following color coding according to the functions of the cell organelles: RED - Energy (Animal: Mitochondria; Plants: Mitochondria and Chloroplasts) YELLOW - Protein Preparation (Animal/Plant: Golgi, Rough-ER, Smooth-ER, Ribosomes, Nucleolous, Nuclear Membrane). BLUE - Genetic Information (Animal/Plant: Nucleus, Chromatin) GREEN - Waste (Animal: Change the Vacuole's name into Lysozome; Plant: Vacuole). BROWN - Physical Support (Animal: Draw Cytoskeleton elements, such as rods and branches; Plants: Cell Wall). Cytoplasm, Cell Membrane - are involved in nearly ALL of these processes. Leave uncolored (or add a very light background color).
