Cells to Organisms 2

Stack for Cells and Organisms

How does the breakdown of food (digestion) help your cells? Digestion releases energy and matter from food for cells to use
Define protist An organism made of a single cell with a nucleus. It is not an animal, plant, bacteria, or fungus
Define bacteria Single-celled organisms that do not have a nucleus or other membrane-bound organelles
Define virus A microbe that is not made of cells that cannot grow, reproduce, or survive outside of a living cell
Define multicellular organism An organism made up of many cells
Define cells The smallest structural unit of life, enclosed by a membrane, makes up all living organisms
Define cell theory All living organisms are made up of cells. Cells are the basic units of structure and function in living organisms. New cells are made from existing cells.
Which organelle conducts cellular respiration? mitochondria
What types of cells have a mitochondria? Animal cells and plant cells
Define the germ theory of disease The theory that microbes cause infectious diseases
What is the function of the cell membrane? The structure that separates the cell from its external environment
Which types of cells have a cell membrane? Animal, plant, bacteria, protists (all cells have a cell membrane)
List these structures from largest to smallest: Tissue, Organelle, Cell, Organ organ←tissue←cell←organelle
Define nucleus The part of the cell that contains genetic material
Where is the genetic material located in a cell? The nucleus
List the following organisms in order from smallest to largest: protist, virus, bacteria virus→bacteria→protist
What are the trade-offs of looking under the microscope with the highest power objective? Harder to see clearly, difficult to locate other organisms, can only see a very small section of the slide at a time
What is the most basic unit of organization for all living things? cell
What type of organism does penicillin kill? Bacteria only
Define unicellular (single-celled) organism. An organism made up of one cell
Define immune system The body’s protection from invading microbes
Which structures do plant cells have that animal cells do not? Cell wall, chloroplasts
What do plant cells use for photosynthesis? (ingredients) Carbon dioxide, water, and sunlight
Where do these things come from? Carbon dioxide comes from the air Water comes from the soil Sunlight energy radiates from the sun
How does the plant obtain them? Plants obtain carbon dioxide by absorbing it from the air, they obtain water by absorbing it from the ground using their roots, they obtain sunlight energy by absorbing it through the chloroplasts
What are the products of photosynthesis? Glucose (food) and oxygen
What do animal cells use for cellular respiration? (ingredients) Glucose and oxygen
Where do these things come from? Glucose comes from food breakdown Oxygen comes from the air
How does the animal obtain them? Animals get glucose by digesting their food Animals get oxygen by breathing through their respiratory systems
What are the products of cellular respiration? Energy, water, and carbon dioxide
