Cell Basics Flashcards
Adoms are
Elements
( ex carbon ,hydrogen ,nitrogen , phosphate,etc)
Organic molecules are
Carbohydrates,lipids,proteins , and nucleic acids
( Biomolecules)
Cell parts with specific functions ( ex cell membrane )
Organelles
1st level of life
Cells
Cells put together are called
Tissues
2 or more tissues working together are called
Organs
All the organs working together are called
Organ systems
Ex Humans and animals
Organism

Which cell has no nucleus ?
Prokaryotic cells
Simple cells - tend to be very small
Prokaryotic
1st cell on Earth
Prokaryotic
Kingdoms include Eubacteria and Archhae bacteria
Prokaryotic
Does not have nucleus but does have nucleic acid / genetic material
Prokaryotic
Most have cell wall
Prokaryotic
Does not have organelles
Prokaryotic
Contains : DNA, Cytoplasm,cell membrane, cell wall ( sometimes ), flagella ( sometimes ), ribosomes , and pili
Prokaryotic
Which cell has a nucleus?
Eukaryotic cells
Has all the kingdoms except 2
Eukaryotic
Found on earth 1.5 billion years ago
Eukaryotic
Has a nuleus and membrane bound organelles
Eukaryotic
Usually bigger than prokaryotic cells
Eukaryotic
What do eukaryotic and prokaryotic cells have in common ?
- Cytoplasm
- ribosomes
- cell membrane
- genetic material
What is different between eukaryotic and prokaryotic cells ?
- DNA enclosed in a nucleus
- membrane bound
What is the Theory of Endosymbiosis?
That large cells engulfed smaller bacteria cells . They lived together, them those cells became membrane bound organelles
What proof do scientist have that supports the Theory of Endosymbiosis?
Mitochondria and chloroplasts have their own DNA
