Answer 1 – 50 1. 2. 3. 4. Cell Wall Large vacuole Chloroplasts Rectangular shape

Question 2 - 10 • What is the main function of the cell wall?

Answer 2 – 10 • To support and protect the cell.

Question 2 - 20 • What are threadlike structures that contain the genetic information of the cell called?

Answer 2 – 20 • Chromosomes

Question 2 - 30 • List two functions of the cytoskeleton.

Answer 2 – 30 • To maintain shape • To aid in movement

Question 2 - 40 • What are the two functions of the nucleus?

Answer 2 – 40 • Contains the cells genetic material in the form of DNA. • Controls cellular activity “control center” of the cell.

Question 2 - 50 • What would be the result of a cell not having ribosomes?

Answer 2 – 50 • No proteins.

Question 3 - 10 • Name an example of an organ.

Answer 3 – 10

Question 3 - 20 • A group of similar cells that perform a particular function is called _____?

Answer 3 – 20 • Tissue

Question 3 - 30 • Who was the first person to identify and see a cell?

Answer 3 – 30 • Robert Hooke

Question 3 - 40 • List the four levels of organization in order from simplest to most complex.

Answer 3 – 40 • Cell > Tissue > Organ System

Question 3 - 50 • What does cell theory state?

Answer 3 – 50 • All living things are composed of cells. • Cells are the basic units of structures and function in living things. • New cells are produced from existing cells.

Question 4 - 10 • Molecules tend to move from an area where they are more concentrated to an area where they are less concentrated. This process is called ________.

Answer 4 – 10 • Diffusion

Question 4 - 20 • A type of membrane that allows some molecules to pass through and does not allow others to pass through.

Answer 4 – 20 • Selectively permeable.

Question 4 - 30 • What is passive transport?

Answer 4 – 30 • Diffusion that does not require energy.

Question 4 - 40 • Explain Osmosis.

Answer 4 – 40 • Water moving from an area of high concentration to and area of low concentration.

Question 4 - 50 • How do facilitated diffusion and active transport differ?

Answer 4 – 50 • FD – movement of larger molecules across the cell membrane through protein channels. Does not require energy. • AT – Movement of material across the cell membrane against a concentration difference. This does require energy.

Question 5 - 10 • Prokaryotes lack a _______.

Answer 5 – 10 • Nucleus.

Question 5 - 20 • The cells in a multicellular organism have specific jobs. This is called cell ______.

Answer 5 – 20 • Specialization

Question 5 - 30

Answer 5 – 30 • Centrioles

Question 5 - 40 • Compare a cell from a unicellular organism with a cell from a multicellular organism.

Answer 5 – 40 • Uni - the cone cell carries out all of the life processes of the organism. • Multi – Cell are specialized to only carry our specific functions. They rely on either specialized cell in the same organism to complete other life processes.

Question 5 - 50 • Compare the cell membrane to a mosaic.

Answer 5 – 50 • Mosaics are made up of many difference tiles and the cell membrane is made up of many difference molecules.
