Eukaryotic Micro Exam 1 Flashcards
General
what is the theory that eukaryotes appeared 2 billion years ago?
symbiosis
organelles
what are the organelles in a eukaryotic cell?
EPR, GA, M, C
- endoplasmic rectilium (Smooth and Rough)
- golgi apparatus
- mitochondria
- chloroplasts
organelles
what are the locomotor organelles in a eukaryotic cell?
F ans C
- flagella
- Cilia
organelles
what composes the cytoskeleton in the eukaryotic cell?
form a network throughout the cytoplasm
- microtubules
- microfilaments
organelles
what are lysosomes?
lys-
vesicles containing enzymes that originate from the Golgi apparatus, involved in intracellular digestion of food particles
organelles
what are vacuoles?
vacuum
membrane-bound sacs containing particles to be digested, excreted or stored
organelles
what are phagosomes
membrane bound vacuoles containing ingested molecules becomes merged with the lysosome
organelles
what is chloroplast?
it converts energy of the sun into chemical energy through photosynthesis can be found in plants and algae
organelles
endoplasmic reticulum
rough? smooth?
rough- continuous net work through cytoplasm from the nuclear membrane to the Golgi; has ribosomes
smooth- Close tubluar Netwerk without ribosomes functions in nutrient processing, synthesis in storage of lipids
organelles
Golgi apparatus
mailman
modifies stores and packs proteins. consist of a stack of flattened sacs called cisternae
organelles
mitochondria
powerhouse
produces and stores ATP, Crystal membrane holds the enzymes and electron carriers of aerobic respiration
organelles
ribosome
rRNA
functions in proteins synthesis
cell wall
describe a cell wall in a eukaryotic cell?
only in some eukaryotic microogranisms
fungi? Algae?
- provides structural support and shape
- fungi have thick inner layer of polysaccharide fibers composed of chitin or celluloseand a thin layer of glycan
- Algae theories in chemical compositio, substance is commonly found in cellulose pectin, silicon dioxide, calcium carbonate
fungi
what are the different morphology of fungi?
M, Y
- mold
- yeast
Fungi
mold
- multicellular
- Long filamentous threads of fungi ate called hyphae produced by releasing spores
- woven or interwining masses of hyphae are called mycelium
