Cells

Across
a type of diffusion that occurs when water molecules diffuse from an area of higher concentration to an area of lower concentration
an organelle that consists of approximately six flattened sacs dealing mostly with proteins synthesized on ribosomes
a solution with a higher osmotic pressure than body fluids
the study of cellular structure and function
structures that extend from the surfaces of cell linings that move in a coordinated manner to move fluids over the cell surfaces
a period when a cell is preparing to divide by manufacturing new material, duplicating membranes, and organelles. The phase of growth.
an organelle consisting of interconnected tubules where many functions occur such as lipid metabolism, detoxifying drugs, and many more.
the primary energy-transferring molecule in body cells
elongated, fluid-filled sacs that can move through the cytoplasm, they are the major sites of chemical reactions and ATP production in the cell.
also called the plasma membrane; it controls the movement of substances into and out of the cell
organelles responsible for protein synthesis; they are attached to the endoplasmic reticulum
the process of substances moving from areas of higher concentration to areas of lower concentration
during this phase of mitosis the chromatids of each chromosome are pulled apart to become individual chromosomes
during this phase of mitosis spindle fibers disappear and chromosomes lengthen and unwind. A nuclear envelope forms around each newly formed nucleus. Cytokinesis finishes creating two separate daughter cells.
Down
singular form structure that extend from a cell enabling it to swim
a double set of lipid membranes that enclose the nucleus of a cell; it also has a protein lining that allows certain molecules to enter and exit the nucleus
tiny sac-like organelles that dispose of cell wastes and worn-out cell parts
all other cells in the human body besides the sex cells
the cell skeleton, cellular scaffolding contained in the cytoplasm
a “mini-nucleus” where ribosomes are formed; made up of mostly RNA and protein
structures needed for proper alignment and separation of chromosomes during mitosis
the gel-like material that fills out a cell; it makes up most of the cell’s volume and suspends the cells organelles
during this phase of mitosis chromosomes become thicker and shorter and centrioles move to opposite poles of the cell
cell division requires a pair of these cylindrical structures
during this phase of mitosis, the chromosomes line up in the middle of the cell and attach to spindle fibers
vacuoles; membranous sacs formed by part of a cell membrane folding in and pinching off.
the semifluid material in living cells, it is part of the cytoplasm, surrounding organelles and other insoluble cytoplasmic structures. Many chemical reactions occur here.
the division of chromosomes in a cell nucleus
