Organelles Flashcards
Site of aerobic cellular respiration, producing ATP from glucose
Mitochondria
Site of photosynthesis; produce glucose using light energy, CO2 and H2O
Chloroplast
Membrane bound sacs, larger than vesicles, stores water and dissolved nutrients
Vacuole
Flattened sacs of membrane with attached ribosomes that synthesize proteins. The proteins are packaged into transport vesicles.
Rough endoplasmic reticulum
Flattened sacs of membrane without attached ribosomes. Synthesizes lipids and buds off to form transport vesicles.
Smooth endoplasmic reticulum
Contains most of the DNA that control the eukaryotic cell. Contains the nucleolus (where ribosomes are made) and chromatin (uncoiled chromosomes).
Nucleus
Consists of flattened membranous sacs; receives transport vesicles from the ER, modifies proteins made in the rER and produces secretory vesicles.
Golgi apparatus
Forms the boundary of the cell, acts as a selective barrier allowing certain materials to pass but not others
Plasma (cell) Membrane
Site of protein synthesis; suspended in the cytosol or attached to the rER.
Ribosomes
Small sac used to carry proteins from the Golgi to the cell membrane for secretion.
Secretory vesicle
Small sac used to carry proteins made on the rER to the Golgi.
Transport vesicle
Protective layer external to the cell membrane, consists of cellulose in plants and chitin in fungus. Protects the cell from bursting under turgor pressure.
Cell Wall
Sacs of digestive enzymes used to digest food and old, worn out cell parts.
Lysosome
Proteins found outside an animal cell that function in support and adhesion so that the cells can connect together to form a tissue
Extracellular matrix
Whip-like structures used for cell locomotion or to create a current next to the cell.
Cilia and Flagella
