Describe the function of the cell wall. Where can the cell wall be found?
The cell wall protects and supports the PLANT cell.
100
What type of microscope focuses light through lenses to produce a magnified image?
Compound light microscope.
100
What is the name for a substance that cannot be broken down into similar elements?
An element.
100
DAILY DOUBLE!! Define selectively permeable.
Selectively permeable (Cell membrane)- a property of cell membranes that allows some substances to pass across it, while others cannot.
100
Describe the two fundamental differences between a plant and an animal cell.
Plant cells have cell walls and chloroplasts.
200
Which organelle is the control center of the cell?
Nucleus
200
What type of microscope focuses an electron beam to highly magnify and sharpen an image?
Electron microscope.
200
DAILY DOUBLE!!!! Why are enzymes important?
Enzymes speed up chemical reactions.
200
Which term prefers to the diffusion of water molecules through a selectively permeable membrane?
Osmosis.
200
What did Anton van Leeuwenhoek do when he saw living things through his microscope?
He observed one celled bacterium from lake water through his microscope and drew pictures of them. He saw the organisms move, which made him realize they were alive, and named them animalcules.
300
What are the small, grain-like organelles that produce proteins inside of cells?
Ribosomes
300
DAILY DOUBLE!!! Cells are the basic ________ of ___________________ and _________________ of living things.
Cells are the basic units of structure and function of living things.
300
What is the name for the large molecules that are formed when sugar molecules combine?
Starches.
300
When materials, such as food particles, are too large to cross the cell membrane the cell changes shape and engulfs the particle in a process called _____________________.
Endocytosis
300
Where are specialized cells only found?
In multi-celled organisms.
400
Describe the function of the Endoplasmic Reticulum.
The ER helps ribosomes produce proteins and helps with transport of proteins.
400
Which scientist was the first to see cells?
Robert Hooke
400
Describe the difference between an organic and an inorganic compound. Give an example of each that your cells need.
Organic compounds: contain carbon- lipids, nucleic acids, carbohydrates (starches), proteins. Inorganic compounds: do not contain carbon- water, salt
400
True or false: In passive transport, materials move from an area of higher concentration to an area of lower concentration through a cell membrane.
True- diffusion.
400
True or False: Cell theory states that cells are produced from non-living cells.
FALSE: Cells are produced from other cells.
500
Compare and contrast mitochondria and chloroplast (must have at least 1 similarity and 1 difference)
Mitochondria: Found in both types of cells, produces energy for the cells from food. Chloroplasts: Found only in plant cells, turn sunlight to sugar (food) for the plant, produces green color.
500
Describe the three components of Cell Theory.
1. All living things are composed of cells. 2. Cells are the basic units of structure and function in living things. 3. All cells are produced from other cells.
500
State the function of each of the following: DNA, enzyme, fat, sugar. Classify them into groups of organic compounds to which they belong.
DNA- nucleic acid, contains genetic material to run the cell. Enzyme- protein, speeds up chemical reactions. Fat- lipids, compose cell membranes and store energy. Sugar- carbohydrate/starch, energy rich, build organelles.
500
Define active transport. What molecules inside of the cell membrane help to make active transport happen?
Active transport- the movement of materials across a cell membrane using cellular energy. Transporter proteins in the cell membrane help this process happen.
500
Use the three points of cell theory to explain how humans and bacteria are similar.
1. All living things are composed of cells- both humans and bacterium are living organisms, so they are made of cells. 2. Cells are the basic units of structure and function in living things- both humans and bacteria are made of cells 3. All cells are produced from other cells- humans are created through reproduction of two cells, bacterium are created through the splitting of two cells
