Learn about the structures and functions of cells, including organelles, cell membrane, nucleus, and more. Understand the differences between plant and animal cells and the levels of organization in living things. Explore concepts such as diffusion, osmosis, and passive and active transport.
E N D

Answer 1 – 10 • Eukaryote
Question 1 - 20 • What are specialized structures within a cell that perform important cell functions?
Answer 1 – 20 • Organelles
Question 1 - 30 • What is the thin, double-layered sheet around the animal cell.
Answer 1 – 30 • Cell membrane
Question 1 - 40 • What are the granular materials visible within the nucleus?
Answer 1 – 40 • Chromatin
Question 1 - 50 • Is this a plant or animal cell? Why?(4 answers)
Answer 1 – 50 • 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 the 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.
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 > 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
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.
