3
Where do cells come from
Preexisting cells the process is called cell division
Unicellular
Organisms with one cell
multicellular
organisms with 2 or more cells
7 characteristics of life
Organization
Growth and development
reproduction
Response to stimuli
Maintaining internal conditions
Use of energy
All living things are made up of cells
What is homeostasis?
organisms to maintain balanced internally
What are the two types of cells?
Prokaryotic and Eukaryotic cells
Both contain genetic material
What are prokaryotic cells?
nyu
A lining doesn’t surround Genetic Material and don’t have organelles is also only found in unicellular
What are eukaryotic cells?
A lining does surround Genetic material are found in multicellular and do have organelles
What are the 3 domains organisms are classified into?
Bacteria
Prokaryotic
Eukaryotic
What is a cell membrane?
An organelle that regulates what goes in and out of the cell
what is a cytoplasm
Provides water and nutrients to the cell and is gel-like material that surrounds all organelles
what is a cell wall
To protect, support, and give structure to the organism
only found in plant cells
What are ribosomes?
create protein for food found on the rough ER
What is the endoplasmic reticulum?
Produce, process, and transport proteins and has two, rough and smooth
What are vacuoles?
Stores water and waste
What is the Golgi apparatus?
Processes proteins to be transported
and is located next to the nucleus
What is the mitochondria?
Powerhouse of the cell and create ATP for the cell for food
What are chloroplasts?
Converts sunlight into sugar, also known as photosynthesis
What is the nucleus?
Controls all cellular activity in the cell and stores DNA
Why is it important the surface area is larger than the volume?
When the volume is small things pass through faster which is good
