cells Flashcards
Organelle composed of flatten sacs that refines, modifies and packages a secretion is
golgi apparatus
Cytosol and organelles make up the
cytoplasm
When a cell engulfs droplets of fluid, known as “cell drinking” it is called
pinocytosis
Short hair like processes for movement is
cilia
Microfilaments and microtubules make up what of the cell?
cytoskeleton
Movement across the membrane requiring energy is called
active transport
The division of the cytoplasm occurs in
cytokinesis
RNA containing particles for protein synthesis are
ribosomes
Membranous sac formed by pinching off pieces of the cell membrane to carry chemicals is a
vesicle
Study of structure and function of cells is
cytology
Loosely coiled fibers of protein and DNA is called
chromosomes
Normal cell death is
apoptosis
Organelle that contains enzymes that function in the synthesis of bile acids, lipids and capable of producing hydrogen peroxide is
peroxisomes
The site of ribosome production is the
nucleus
Changes a cell undergoes from the time it is formed until it reproduces is called the
cell cycle
The fluids outside of the cells membrane is referred to as interstitial fluid or
extracellular fluid
The division of nuclear material occurs in
mitosis
Rough endoplasmic reticulum (ER) contains
ribosomes
An organelle with a tail like structure for movement is
flagella
A period of growth and replication occurs in
interphase
Membranous sacs that contain digestive enzymes are
lysosomes
A special case of diffusion using water is
osmosis
When a cell engulfs and digests solids, known as “cell eating”, it is called
phagocytosis
The powerhouse of the cell is the
mitochondria
Organelle of flatten sacs and vesicles that provide transport in a cell is
endoplasmic reticulum
The cell membrane is extremely thin and
selectively permeable
Organelle that functions for cell division is
centrosome
What regulates the movement in and out of the cell?
cell membrane
Smallest functional units of life is a
cell
What type of diffusion uses a carrier molecule to move across the cell membrane?
facilitated
Movement across the membrane requiring no energy is called
passive mechanism
The specialization of the cell is called
differentiation
The fluids contained inside the cell is referred to as
intracellular fluid
Net movement of random molecules from an area of great to one of lesser concentration is called
diffusion
