Branch of Biology that studies cell and their parts
Robert Hooke
1665= discovered cells in cork and named them after the rooms in a monestary; blocks linked together like legos
Anton Van Leeuwenhoek
1st to describe living, moving cells; swimming in water, tooth plaque; 1st to see blood cells
1800's French Biologist; tried to repeat Hooke's experiment but discovered major difference= his cells had live material inside; named it Protoplasm
2 German Scientists
Schleiden= botanist
Schwann= Zoologist
looked at every creature they could in a microscope; always found cells as building blocks
3rd Scientist mid 1800's= pathologist- studies disease; very interested in tumor development; watched tumors in microscopes; conclusion= always started with a single cell that copied into a pile and spread
What 3 scientists helped write the Cell Theory?
Schleiden, Schwann, Virchow
What is the Cell Theory?
2 principles:
1)all living things are made of cells as building blocks
2)all cells come from parent cells by normal reproduction
What are the six characteristics of life?
Hint: Hungry Corey Eats Oranges Growing Rapidly
building blocks (different shapes and sizes)
How are plant cells arranged?
very neat and organized; tiny parts that do particular jobs
What are the basic things in a plant cell? (5)
organelles, cytoplasm, cell membrane, cell wall, nucleus
What are the 2 types of cells?
Plant=cell wall, little movement; autotroph
Animal= only membrane, lots of movement; heterotroph
getting and using food
various activities that rebalance a creature; drinking then peeing
add stuff; cell parts control raw materials and can construct parts
make new identical cell; division or sex
Cell Wall (J&S)
job: to support and protect plant cells
structure: pick correct materials (cellulose), add hardener
What is a membrane made of?
2 layers of protein globs, 1 layer of lipids (fat)
What is the job of a membrane?
to control what goes in and out of the cell (selectively permiable)
What types of cells have a membrane?
ALL cells have membranes
What do the tiny pores only let in?
tiny molecules= H2O, O, sometimes carbon monoxide sneaks in :(
What do cells use as a general building material?
cell membrane
What does the Nucleus do?
it controls the entire cell's activities and holds all of the DNA / info and shares it throughout the cell
What does DNA stand for?
Deoxyribo Nucleic Acid
What do the Nucleolus do?
copy sections of DNA/ found in the Nucleus
What does the Endoplasmic Reticulum do?
acts as a transportation device from the pores of the Nucleus to the pores of the Membrane
What types of vacuoles are in Plant cells?
water vacuoles
What types of vacuoles are in Animal cells?
Food vacuoles and contractile vacuoles
What do autotrophs make and heterotrophs use
what are the organelles in plants that make and store the food?
what is the more specific name for the food chloroplasts make?
glucose sugar
What does the work that the organelles get credit for?
enzymes :)
Where do the enzymes :) "work"?
in the Grana
more Grana=...?
more enzymes
What is the process of turing light energy into glucose called?
What types of cells have Mitochondria?
All cells
What are the work stations called where the Mitochondria enzymes work?
what is storing the loose energy temporarily called?
When does cytoplasmic streaming occur?
when the cell gets light (like sun light)
What types of cells are Plastids in?
Plant cells
What are the 3 different types of membrane bags that hold various colors?
chromoplasts (bright=red,yellow, orange), chloroplasts (green), leucoplasts (white)
What do Ribosomes do?
they follow the recipe sent from the Nucleus and make the protein
What do Golgi Bodies do?
store and later deliver proteins (warehouse)
What are lysosomes?
self destructive enzymes that destroy old body parts or the whole cell (tadpoles)
Describe a tadpoles leg development
has a tail then the lysosomes "self destruct" and eat the tail away then reuse the membrane material to make legs
