⩥ primary function of peroxisome
Answer: oxidize certain molecules normally found in the cell
⩥ primary function of centrosomes
Answer: duplicates and then helps with cell division
⩥ primary function of cilla
Answer: moves water relative to the cell in a regular movement of cilla
⩥ primary function of flagella
Answer: functions as a sensory organelle being sensitive to chemicals
and temperatures outside the cell
⩥ main function of vesicle
Answer: help move proteins and molecules from one part of the cell to
another
⩥ function of nuclear envelope
,Answer: creates a barrier between cytoplasm and eukaryotic cells.
control substance in and out of nucleus
⩥ function of nuclear pores
Answer: Regulate the movement of materials across the nuclear
envelope
⩥ function of nucleolus
Answer: produces ribosomes
⩥ function of chromatin
Answer: efficiently package DNA into a small volume to fit into the
nucleus of a cell and protect the DNA structure and sequence
⩥ Define diffusion
Answer: movement of molecules from high concentration to low
concentration
⩥ Define facilitated diffusion
Answer: Movement of specific molecules across cell membranes
through protein channels
⩥ Define filtration
, Answer: the process that separates a solid from the liquid in a
heterogeneous mixture
⩥ Define active transport
Answer: the movement of ions or molecules across a cell membrane into
a region of higher concentration, assisted by enzymes and requiring
energy.
⩥ Define endocytosis
Answer: the taking in of matter by a living cell by invagination of its
membrane to form a vacuole.
⩥ Define phagocytosis
Answer: cellular eating
⩥ Define pinocytosis
Answer: Cell drinking
⩥ Define exocytosis
Answer: a process by which the contents of a cell vacuole are released to
the exterior through fusion of the vacuole membrane with the cell
membrane.
⩥ Does diffusion require ATP?
