Cells

5 Written Questions

1. A type of active transport which large molecules are engulfed and taken into the cell
2. The function of this organelle is to separate the interior of a cell from the outside. It is a semi-permeable lipid bi-layer surrounding all cells
3. A type of passive transport which molecules of water move in and out of a membrane with a concentration gradient
4. A part of a chromosome (DNA) that specifies traits of an organism
5. The function of this organelle is protein synthesis. Many of these organelles are located on the rough ER

5 Matching Questions

1. Facilitated diffusion
2. Cell wall
3. Passive transport
4. Active Transport
5. E.R.

1. a The function of this organelle is to produce lipids (smooth ER) and transport molecules within the cell (smooth and rough ER)
2. b The function of this organelle is to provide an extra layer of protection for plant cells
3. c Transport of substances through a membrane which requires energy. Molecules move against the concentration gradient from an area of low concentration to an area of higher concentration
4. d A type of passive transport which large molecules move in and out of a membrane through a protein
5. e Transport of substances through a membrane which requires NO energy. Molecules move with the concentration gradient from an area of higher concentration to an area of lower concentration
