Definitions
Cell Membrane
Diffusion & Osmosis
100
The basic structural and functional unit of life.
What is a cell?
100
Flagelum, cytoplasm, nucleous, chromosomes, vacuole, cell membrane.
What is an animal cell?
100
The theory that states that all living things consist of cells.
What is the cell theory?
100
A natural gatekeeper around a cell.
What is a cell membrane?
100
The movement of particles from an area of higher concentration to a lower concentration.
What is diffusion?
200
Plants obtain energy from sunlight. Animals eat plants, other animals or both to obtain energy.
What is living things require energy?
200
Cell membrane, cytoplasm, chromosomes, nucleous, cell wall, vacuole, chloroplast.
What is plant cells?
200
A microscope that uses beams of electrons instead of beams of light.
What is the electron microscope?
200
Made up of 2 layers of fat particles and many protiens are embedded.
What is the cell membrane made of?
200
The diffusion of water across a selectively permable membrane of an area of higher water concentration to a lower water concentration.
What is osmosis?
300
A broken bone heals over time.
What is living things repair themselves?
300
Hair-like projections that help propel the cell or move the substance surrounding the cell.
What is cilia?
300
The outward pressure that is exerted on a plant cell wall by the cell contents when water is taken in by osmosis.
What is tugor pressure?
300
A membrane that allows only certain substances to pass through it.
What is a selectively permable membrane?
300
Plays an important role in how living things obtain energy and get rid of waste.
What does diffusion do?
400
May appear to have some, but not all of the characteristics of living things.
What is a non-living thing?
400
A small structure found within a cell.
What is an organelle?
400
Site of photosynthesis; In a plant cell absorbs sunlight, carbon dioxide, and water to make food.
What is chloroplast?
400
The cell membrane blocks harmful substances from entering the cell and removes waste.
What does the cell membrane do?
400
Common solutes in cells.
What is sugars, salts, or proteins?
500
Started as one cell, but has divided into more.
What is all living things?
500
The watery substance in a cell in which the organelles are suspended.
What is cytoplasm?
500
A tail like structure that propel cells through their environment.
What is flagellum?
500
Allowing passage
What is permable?
500
Contains nutrients that can help plants grow.
What is a fertilizer?
