Living Things
How many levels are there in taxonomic classification?
8 levels
What are the 2 different types of plants?
Vascular and nonvascular
Who was the first person to observe cells under a microscope?
Robert Hooke
What organelle does photosynthesis happen in?
The chloroplast
What is the difference between active and passive transport?
Passive is molecules moving freely. Active requires energy input from the cell.
How are scientific names written?
In italics using the genus and species.
How do invertebrates support their bodies?
They have an exoskeleton.
What are the 3 principles of cell theory?
All living things are made of cells. Cells are the basic units of structure and function. All new cells are produced from existing cells.
What creates more energy cellular respiration or fermentation?
Cellular respiration
What are the 3 forms of passive transport?
Simple diffusion, osmosis, and facilitated diffusion.
What are 6 characteristics that all living things have in common?
They all reproduce, contain genetic material, grow and develop, respond to their surroundings, are made of cells, and obtain energy.
What are 3 differences between animal and plant cells?
Plant cells have a chloroplast, large vacuole, and cell wall.
What is the difference between magnification and resolution?
Magnification makes small things larger. Resolution makes small things clearer.
How many oxygen molecules does one cycle of cellular respiration use? How many carbon dioxide and water molecules does it make in one cycle?
It requires 6 oxygen molecules. After one cycle it makes 6 water molecules and 6 carbon dioxide molecules.
What is the difference between endocytosis and exocytosis?
Endocytosis is how cells bring large particles inside itself and exocytosis is how a cell removes large particles.
What are the 3 domains and which includes the different kingdoms? What are the different kingdoms?
The three domains are bacteria, archaea, and eukarya. Domain eukarya includes the different kingdoms which are animalia, plantae, protista, and fungi.
Name 3 groups of vertebrate animals.
Mammals, reptiles, amphibians, birds, and fish
What are the levels of organization (5 total)?
Atoms make up molecules. Molecules combined make cells. Cells make up tissues. Tissues make organs. Organs combined make organ systems.
What do plants use glucose for?
Plants use glucose for food and in building their cell walls. Other molecules are stored in the cells for later use, such as potatoes and carrots.
What would happen to a cell placed in extremely salty water?
The salt would go into the cell and water would leave the cell.
How does the theory of evolution support how organisms are classified?
Scientists can look at the organisms DNA and compare it to determine common ancestors, and how closely things are related based on similarities in it.
What are the differences between plants and fungi?
Plants have stems, leaves, and roots. Fungi have hyphae and fruiting bodies. Plants reproduce using seeds, while fungi uses spores. Not all fungi are autotrophic.
How do ribosomes, the endoplasmic reticulum, and the golgi apparatus work together?
Ribosomes make proteins. The endoplasmic reticulum receives those proteins and processes them. Then the golgi apparatus then takes those proteins and sends them to where they need to go in the cell.
Write out the chemical equation for photosynthesis and cellular respiration. You may only use the molecular formulas.
Photosynthesis:
light energy + 6 CO2 + 6 H2O -> C6H12O6 + 6 O2
Cellular Respiration:
6 O2 + C6H12O6 -> 6 CO2 + 6 H2O + Energy
Why is it not healthy to drink or get an IV of distilled water?
Because there are no solutes in the water it would all go into the cells and cause them to swell up.
