Download What are all living things composed of?

List some common foods that are high
in protein, lipids, carbohydrates, and
nucleic acids.
Agenda for Monday Nov 7th
1. Cell theory
2. Organelle Posters
Cell Theory
Robert Hooke
• Made simple microscope
• Looked at cork
– observed small box like
structures
– Called them cellulae (small
rooms) = cells
Cell Theory
Anton van Leewenhoek
• Created a microscope
• Saw living things in milk, pond water, etc
Matthias Schlieden
• Looked at plants and concluded they were
composed of cells
Theodore Schwann
• Animals composed of cells
Rudolph Virchow
• All cells come from existing cells
Cell Theory
1. All living things are composed of one or more
cells
2. Cells are the basic unit of structure and
organization of all living organisms
3. Cells arise only from previously existing cells
1. Cells pass on copies of their genetic material to their
daughter cells
List the 3 parts to the cell theory.

Agenda for Wednesday Nov 9th
1. Go over organelles

Prokaryotic vs. Eukaryotic
** Organelles – specialized structures in cells that carryout specific
functions
Prokaryotic Cells
• Prokaryotes
• Small and simple
• Circular DNA
• No nucleus or membrane
bound organelles
• Usually unicellular
– Bacteria
Eukaryotic Cells
• Eukaryotes
• Higher level organisms
and function
• Most organisms (plants,
animals) are made up of
eukaryotic cells
• Nucleus –organelle that
contains DNA (linear)
– Other membrane bound
organelles
Plant Cell
Animal Cell
Organelles in the Cell
• Plasma membrane
– Controls what enters and leaves cell
– Both prokaryotic and eukaryotic cells
• Cytoplasm - Liquid within the cell
• Cell Wall – plants and fungi
– support and protect the cell
– Plants’ = cellulose
Fungi = chitin
Organelles
• Nucleus - contains DNA
– DNA – instructions needed to
produce proteins
• Chromatin
• Nucleolus – within nucleus
– Ribosomal RNA (rRNA)
• Nucleoplasma – liquid within
nucleus
Endoplasmic Reticulum
• Single, continuous membrane
• Pipes, tubes and tunnels in cell
– Superhighway of the cell
• 2 kinds: Rough ER + Smooth ER
– Rough ER - Studded, or covered, with ribosomes
• Ribosomes – site of protein synthesis
Golgi Apparatus
• Store, package, sort and modify proteins
– The UPS of the cell
Vesicles and Vacuoles
Vacuoles
• Store material
• Not usually found in animal cells
Lysosomes &Peroxisomes
• Contain digestive enzymes
• Breakdown cell's food and wastes
Mitochondria
• Produces energy for the cell
– Cell's "power house“
– Converts sugars into energy
(ATP)
• Composed of 2 membranes
Chloroplasts
• Found only in green plant cells and algae
• Site of photosynthesis
– Use the sun’s energy and convert to chemical energy
• Contain pigment chlorophyll
Cilia/Flagella
• Cilia – all over cell, smaller,
aid in movement of cell
• Flagella – longer projections,
aid in movement of cell
Other cell parts
Cytoskeleton
• Framework inside cell
• Support and movement
• Composed of microfilaments, intermediate
filaments, microtubules
Centrioles
• Aid in cell division
• Found only in animal cells
Plant vs. Animal Cell
Plant Cells
• Cell Wall
– And cell membrane
• Chloroplasts
• Large vacuoles
Animal Cells
• No Cell wall
– Cell membrane only
• No Chloroplast
• Small or absent vacuoles
All other organelles are the same in each cell
