Organelles
What produces proteins needed by the cell?
Ribosomes
Nucleus
Directs cell's activities
Where is the Nucleolus?
Inside the Nucleus
What is an Element?
An element is any substance that can't be broken down further into anything simpler.
What type of transport uses energy
Active
Passive transport uses no energy
What does a Lysosome do?
Break down food particles and worn-out cell parts in an ANIMAL cell
Vacuole
Storage
Where is cytoplasm?
Filling most of the cell (Thick clear gel-like substance)
What is a compound?
Compounds are formed when two or more elements combine.
Carbon dioxide is a compound made of carbon and oxygen (CO2 one Carbon and 2 Oxygen)
What are the three parts of Cell Theory?
All living things are made of cells
Cells are the basic units of all living things
All cells are made from cells
What PLANT organelle makes food from sunlight?
Chloroplast
Mitochondria
Converts food into energy used by the cell
Where is a cell wall?
On the outside of a PLANT cell
Sugars and Starches are compounds called
Carbohydrates
What is the process called when a cell membrane changes shape and engulfs (surrounds) a particle?
Endocytosis
Exocytosis is the opposite. This is when a particle leaves a cell.
What is the function of a cell wall in a PLANT cell?
Act as reinforcement for the cell membrane and gives the cell shape
Golgi Apparatus
Packages and distributes materials from the ER
What two items do PLANT cells have that ANIMAL cells do not?
Cell wall and Chloroplast
What are lipids?
Fats and oils
What are the 3 powers of the objective lenses?
4x, 10x and 40x
Remember that the eye piece is 10x and won't change
looking through the eye piece and a power 40 lens gives you magnification of 400x (10x40=400)
What organelle is very large in a PLANT cell, but much much smaller in an ANIMAL cell?
Vacuole
Endoplasmic Reticulum (ER)
Helps make proteins and other substances
What item does an ANIMAL cell have that a PLANT cell doesn't?
Lysosomes
What group of proteins speed up chemical reactions?
Enzymes
The process by which molecules move from higher concentration to an area of lower concentration.
Diffusion
