Chapter 3: Plant cells Flashcards
(14 cards)
Cell Theory is…
The idea that all life on earth is composed of small individual organisms called cells.
Prokaryotes are…
primitive/ simple cells not containing a nucleus or a number of other organelles
Eukaryotes are…
Cells that contain organelles and a membrane bound nucleus.
Plant cells differ from animal cells in that…
They contain chloroplasts, and vacuoles
Organelles are…
The functional parts of a cell
The Plasma Membrane is…
The phospholipid bilayer that contains the cell and facilitates osmosis
The Nucleus is…
The housing for DNA within a nuclear envelope, the cell “Control Center”
The endoplasmic reticulum is…
The folded pouches that play a role in protein synthesis
Golgi apparatus…
Another stack of membrane pouches that process proteins
Peroxisomes are…
found in all eukaryotic cells. Controlling oxidation reactions that are important for fat breakdowns, toxin breakdown and stress/aging signaling
Lysosomes are…
only found in animal cells. They are acidic on the inside and can be compared to the stomach for the cell. It breaks down the macronutrient polymers into monomers
Mitochondria are…
THE POWERHOUSE OF THE CELL: essential for cellular respiration and the conversion of oxygen into ATP energy compounds.
A plastid is:
a membrane-bound organelle found in the cells of plants, algae, and other eukaryotic organisms. Plastids are essentially individual organelles that formed symbiotic relationships with larger predator cells.
