- c Active transport process where a cell engulfs materials with a portion of the cell's plasma membrane and releases the contents inside of the cell to form a vacuole.

5 True/False questions
mitosis → Cell's division (PMAT) of the nucleus. Final product is 2 daughter cells that are exactly like the parent cell., asexual reproduction and contains same number of chromosomes.
diffusion → A process that separates materials through a membrane based on the size of their particles.
tight junction → Communicating Junctions; channels that allow small molecules to flow through protein-lined pores between cells. common in the heart and embryonic cells.
anaphase → 3rd phase; the chromatids of each chromosome separate at the centromere and move in opposite poles of the spindle.
triplet → biological unit of hereditary information located in chromatin consisting of a specific nucleotide sequence in DNA (or RNA, in some viruses). that transmits hereditary information.
