chapter 3 - cellular level of organization Flashcards
what is a gelatin-like substance?
cytoplasm
what contains the genetic makeup of a cell?
nucleus
what are sites of protein synthesis?
ribosome
what is the powerhouse of the cell?
mitochondria
what generates ATP?
mitochondria
what is another name for “little bladder”?
vesicle
what is a spherical sac formed by budding off from a membrane?
vesicle
what is cell eating?
phagocytosis
what is cell drinking?
pinocytosis
what is it called when the vesicles fuse with the plasma membrane, releasing their contents into extracellular fluid outside of the cell?
exocytosis
what is a combination of endocytosis and exocytosis?
transcytosis
what are materials that move into a cell in a vesicle formed from the plasma membrane?
endocytosis
what are the three main parts of an eukaryotic cell?
plasma membrane, cytoplasm, and nucleus
what is responsible for packing up newly made proteins and shipping them off to where they belong?
golgi complex
what is it called when a cell makes a copy of the blueprint inside of the nucleus?
transcription
what is it called when the copy of the nucleus is taken and made outside of the cell?
translation
what contains mRNA?
transcription
what contains rRNA and tRNA?
translation
what reads the transcription?
ribosomes
in cell division, what replicates it’s DNA?
interphase
in cell division, what stage is it where cell division takes places?
mitotic phase
what are the mitotic phases?
prophase, metaphase, anaphase, telophase (please massage Arnold’s traps)
where does growth and replication happen (without cell division)?
interphase
where does cell division spend most of it’s time?
interphase
what phase is genetic information wound up into chromosomes?
prophase
what phase do chromatin pairs line up in the center of the cell?
metaphase
what phase does the cell begin to split?
anaphase
what phase is it when two identical nuclei are formed around the identical sets of chromosomes?
telophase
