Answer 1 – 40 Chromatin

Question Is this a plant or animal cell? Why?(4 answers)

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

Question What is the main function of the cell wall?

Answer 2 – 10 To support and protect the cell.

Question What are the threadlike structures that contain the genetic information of the cell called?

Answer 2 – 20 Chromosomes

Question List two functions of the cytoskeleton.

Answer 2 – 30 To maintain shape To aid in movement

Question 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 What would be the result of a cell not having ribosomes?

Answer 2 – 50 No proteins.

Question Name an example of an organ.

Answer 3 – 10

Question A group of similar cells that perform a particular function is called _________?

Answer 3 – 20 Tissue

Question Who was the first person to identify and see a cell?

Answer 3 – 30 Robert Hooke

Question List the four levels of organization in order from simplest to most complex.

Answer 3 – 40 Cell > Tissue > Organ > Organ System

Question 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 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 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 What is passive transport?

Answer 4 – 30 Diffusion that does not require energy.

Question Explain Osmosis.

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

Question 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 Prokaryotes lack a ______________.

Answer 5 – 10 Nucleus.

Question The cells in a multicellular organism have specific jobs. This is called cell ____________.

Answer 5 – 20 Specialization

Question

Answer 5 – 30 Centrioles

Question 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 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.
