Chapter 4 - Cell Structure Flashcards
Three tenets of Cell Theory.
- All living things are made of cells.
- The cell is the basic unit of life.
- Cells can only come from other cells.
Cell’s main ingredient
Plasma membrane
What does prokaryote mean?
Pro - before
Karyote - nucleus
TRUE or FALSE
Prokaryotic cells do not have membrane enclosed nucleus.
TRUE
Everything in the cell but NOT in the nucleus
Cytoplasm
Everything in the cell that is not in an organelle
Cytosol
Specialized compartments within a cell that perform distinct functions
Organelles
What are the smallest cells and they lack organelles?
Prokaryotic
What is a “eukaryote”
animal and plant
Which are larger cells … prokaryote or eukaryote?
Eukaryote
What part of cell contains nuclear DNA
Nucleus
Mitochondria’s main function
Extract energy from food and store it in ATP
Eurkaryotic cells - linear or circular?
Linear
Prokaryotic cells - linear or circular?
Circular
All Eukaryotic cells have
Mitochondria
Name of leading explanation for the evolution of mitochondria and chloroplasts.
Endosymbiant Hypothesis
What is a eukaryote?
Has a true nucleus.
What structures are found in eukaryotes?
CD MPR
CAMPER - no vowels
chloroplast, DNA,
mitochondria, photosynthesis, ribosomes
Which organelles are part of the endomembrane system?
ErGaL
(EAGLE)
Endoplasmic Reticulum
Golgi apparatus
lysosomes
What is purpose of endomembrane system?
To build proteins and lipids - to package them to get them where they need to go
What propels the cells through fluid?
Cilia/flagella
What is the cytoskeleton made up of?
Protein
The cytoskeleton regulates:
Cell shape
Cell movement
Organelle movement
Cell division
