Across
- Cell's hereditary information
- All the material between the cell membrane and the nucleus
- Process of taking materials inside the cell by means of infolding of the cell membrane
- The movement of materials from an area of lower
concentration to an area of higher concentration, requiring the use of energy
- Double-membraned layer surrounding the nucleus
- The diffusion of water across a semipermeable membrane
- When the concentration of solutes in a solution outside the cell is greater than inside the cell, causing the cell to lose water
- Sometimes also referred to as a double-layed sheet
- Specialized structures that perform certain functions in a cell
- Storage organelle area of water, food, salts, proteins, and carbohydrates
- Hollow tubes that serve as "tracks" along which cellular organelles move
- The removal of large amounts of material from the cell by fusing a vacuole with the cell membrane
- A group of
similar cells that perform a particular function
- Organelle where components of the cell membrane are assembled and some proteins are modified; also serve as a cell's conveyor belt
- UPS organelle of the cell; attached
lipids and carbohydrates to proteins
- A strong layer around the cell membrane; found in plants, fungi, protists, and bacteria
- May groups of tissues working together
- Granular DNA that is visible with a cell's nucleus
- The diffusion of large molecules across the membrane via protein channels, requiring no energy input

Down
- Organelle which uses the sun's energy to make energy-rich food molecules
- The mass of a solute in a given solution
- Cells in multicellular organisms each perform a particular function
- Where ribosomes are assembled in the cell
- Organelle that uses food to make high-energy molecules that the cell can use for growth, development, and movement
- Small tubes that provide a tough, flexible framework that supports the cell
- The basic unit of life
- When large particles are taken into a cell
- A large structure that contains the cell's genetic material and controls the cell's activities
- A group of organs that work together to perform a specific function
- Helps the cells
maintaining shape and move
- When a cell divides, chromatin becomes condensed and visible, forming these
- Small organelle filled with digestive enzymes
- Cells with a nucleus; include plants, animals, protists, and fungi
- Some substances may pass through while other may not
- Causes substances to move from an area of high concentration to lower concentration, without requiring energy
- When the concentration of solutes in a solution outside the cell is equal to that inside the cell
- A thin, flexible barrier around the cell; made of proteins, lipids, and carbohydrates
- Where proteins are assembled
- Cells without a nucleus; includes bacteria
- When the concentration of solutes in a solution outside the cell is less than inside the cell, causing the cell to gain water
