REAL Knowledge Basic Biology

The power house of the cell;Convert oxygen and nutrients into energy Mitochondria (a)
Protects the cell and regulates molecules entering and leaving the cell Cell Membrane (a)
Helps hold the cell’s organelles in place Cytoplasm (a)
Stores the DNA and coordinates the cell’s activities, basically, it is the brain Nucleus (a)
Build protein for the cell to use Ribosomes (a)
Break down waste into simple compounds for other organelles to use Lysosomes (a)
Manufactures and transports chemical compounds to and from the nucleus Endoplasmic Reticulum (a)
Modifies proteins and fats built in the cell and prepares them for storage or transports them outside the cell Golgi Apparatus (a)
Digest toxic materials in the cell Peroxisomes (a)
Stores waste products and maintains the PH level of the cell Vacuole (a)
Help the cell divide during mitosis and meiosis Centrioles (a)
Releases materials from the cell, usually waste from the cell Secretory Vesicles (a)
Absorb nutrients for the cell and help with cell movement Microvilli (a)
Provides structural support for the cell Cytoskeleton (a)
Provide structural support for the cytoskeleton and connect to chromosomes during cell division Microtubules (a)
Provide structural support for the cytoskeleton Microfilaments (a)
Main protection barrier of plant cells Cell Wall (p)
Provides structural support for the cell Cytoskeleton (p)
Converts sunlight to energy by a process called photosynthesis Chloroplast (p)
Enables transport of material and communication to adjacent cells Plasmodesmata
Transports materials within the cell and help store enzymes Vescicle (p)
Denoting or relating to a solution having the same osmotic pressure as some other solution, especially one in a cell or a body fluid. Isotonic
Having a higher osmotic pressure than a particular fluid, typically a body fluid or intracellular fluid. Hypertonic
Having a lower osmotic pressure than a particular fluid, typically a body fluid or intracellular fluid. Hypotonic
Water fearing (tail) Hydrophobic
Water loving (head) Hydrophilic
Types of consumers Herbivores, carnivores, omnivores, and decomposers
A carnivore at the topmost level in a food chain that feeds on other carnivores; an animal that feeds only on secondary consumers. Tertiary Consumers
Each of several hierarchical levels in an ecosystem, comprising organisms that share the same function in the food chain and the same nutritional relationship to the primary sources of energy. Trophic Level
The hypothesis that evolutionary development is marked by isolated episodes of rapid speciation between long periods of little or no change. Punctuated Equilibrium
The hypothesis that evolution proceeds chiefly by the accumulation of gradual changes (in contrast to the punctuationist model). Gradualism
A mode of natural selection in which a single phenotype is favored, causing the allele frequency to continuously shift in one direction Directional Selection
(or diversifying selection) a mode of natural selection in which extreme values for a trait are favored over intermediate values Disruptive Selection
Type of natural selection in which genetic diversity decreases as the population stabilizes on a particular trait value Stabilizing Selection
Water tends to stick to unlike substances Adhesion
Water molecules cling together due to hydrogen bonds Cohesion
