Cell Organelles, Prokaryotes and Eukaryotes, etc. Flashcards
Nucleus
Controls cell activity
Cytoplasm/Cytosol
Jelly like material inside. Most organelles floats within it. Holds organelles in place.
Cell Membrane
Allows materials to enter and exit the cell.
Cell wall
Provides tensile strength and protection against mechanical and osmotic stress.
Chloroplast
Converts light energy into relatively stable chemical energy via the photosynthetic process. Found only in plant cells. Endosymbiotic idea
Large Central Vacuole
Stores water and manages turgor pressure in a plant cell. Helps sequester waste products
Ribosomes
Creates protein in the cell.
Mitochondrion
Powerhouse of the cell. Embosymbiotic idea
Golgi Apparatus/Bodies
Where the proteins received from ER are further processed (checked, modified, packaged)
Lysosome
Breaks down food and waste. Found in both plant and animal cells.
Nucleolus
Makes ribosomes. Found in both plant and animal cells.
Centrioles
Helps cell divide
Rough ER
Stores ribosomes, and quality control of proteins.
Smooth ER
Makes lipids, breaks down toxins.
Vesicles
membrane bound container used to carry substances throughout the cell
peroxisome
Protects cells from toxins
Cilium
for movement and gathering food
Flagella
tail used for movement
Cytoskeleton
Supports and shapes cell
What two organelles have the endosymbiotic hypothesis?
Chloroplast and mitochondrian.
What is a eukaryotic cell?
The more complex cell of the two.
What is a prokaryotic cell?
The simpler cell of the two.
In what type of cell is the nucleus present?
Eukaryotic
Which of the two domains have membrane bound organelles?
Eukaryotic
