directs the cells activities
what is the nucleus
forms a barrier controls what goes in and out of the cell.
what is the cell membrane
what is the diffusion of water molecules across a selectively permeable membrane
what is osmosis
what is the order of the cell cycle?
what is interphase, prophase, metaphase, anaphase, telophase, cytokinesis
helps make proteins and other substances
what is the endoplasmic reticulum
packages and distributes materials.
what is the golgi apparatus
the process by which molecules move from an area of higher concentration to an area of lower concentration.
what is diffusion
what stage of the cell cycle takes he longest
what is interphase
gel-like fluid fills most of the cell; moves nutrients, proteins,and organelles within the cell.
what is the cytoplasm
produce proteins needed by the cell
what is the ribosomes
what allows large particles to leave the cell ( not cell membrane)
what is endocytosis
during what does the cell's nucleus divide into two new nuclei and one set of DNA is distributed into each daughter cells
what is mitosis
converts energy into food to use energy used by the cell
what is the mitochondria
what is the nucleus
an organelle that Directs the cells activites
what means some substances can move across the cell membrane and some cannot
what is selectively permeable
in a process called what does the cell make a copy of the DNA in its nucleus before cell division.
what is replication
stores water, food, waste products.
what is the vacuole
break down food particles and worn-out cell parts.
what is the lysosomes
what is the cell membrane taking particles into the cell by changing shape and engulfing the particles.
what is exocytosis
which transport has ATP
Active transport
