QUESTIONS AND ANSWERS
Cell cycle. ANSWER -life cycle of a cell, which includes the phases G0, G1, S, G2, and M;
during the M phase, the cell divides into two identical daughter cells
Cell membrane. ANSWER -lipoprotein structure that separates the interior of a cell from
the external environment; regulates what can enter and leave a cell
Cytoplasm. ANSWER -lies within the cell membrane; contains organelles for producing
proteins, energy, and so on
diffusion. ANSWER -movement of solutes from an area of high concentration to an area of
low concentration across a concentration gradient
endocytosis. ANSWER -the process of engulfing substances and moving them into a cell
by extending the cell membrane around the substance; pinocytosis and phagocytosis are
two kinds of endocytosis
endoplasmic reticulum. ANSWER -fine network of interconnected channels known as
cisternae found in the cytoplasm; site of chemical reactions within the cell
exocytosis. ANSWER -removal of substances from a cell by pushing them through the cell
membrane
genes. ANSWER -sequences of DNA that control basic cell functions and allow for cell
division
