CORRECT VERIFIED ANSWERS/ ALREADY GRADED
A+ (BRAND NEW!!)
Nuclear membrane - ANSWER - Allows genetic code to communicate
with ribosomes. Controls what comes in and out of the cell.
Nucleus - ANSWER - Control center of cell, has a membrane which
holds and protects chromatin.
Nucleolus - ANSWER - Circular structure inside nucleus- makes
ribosomes
Chromatin - ANSWER - DNA bundled in nucleus with proteins- code
for proteins (genetic code)- chromosomes allow for DNA to be
packaged.
Centriole - ANSWER - 2 perpendicular bundles of tubes- involved in
cell division (In animals ONLY)
Chloroplast - ANSWER - Oval-shaped organelle filled with stacks of
protein- main site of photosynthesis (In plants ONLY)
pg. 1
,Cell wall - ANSWER - Outer coverings of cell- maintains structure (In
plants ONLY)
Cell Cycle - ANSWER - Entire period of cells life (Interphase, G1, G2,
Mitosis)
Independent variable - ANSWER - Variable that is manipulated- should
only be one
Dependent variable - ANSWER - Measure variable- responds to changes
in independent variable
Biological diversity - ANSWER - Number and variety of species and
ecosystems on earth (Species, Structural, Genetic)
Biodiversity importance - ANSWER - More biodiversity= more resistant
to change
More feeding relationships- ensure food supply
Nutrient cycling
Biodiversity threats - ANSWER - Habitat loss
Climate change
Over-exploitation
pg. 2
,Taxonomy - ANSWER - The science of classifying all organisms (living
and fossil)
Dichotomos key - ANSWER - Sort organisms into smaller and smaller
groups based on characteristics
Carl Linnaeus - ANSWER - The father of taxonomy who classified
organisms based on similarities
Binomial Nomenclature - ANSWER - Formal system of naming species
where each species is assigned a genus name
Genus - ANSWER - Group of species that share similar characteristics
Morphology - ANSWER - Classifying based on physical appearance and
characteristic
Phylogeny - ANSWER - Study of evolutionary relatedness between and
among species
Phylogenetic tree - ANSWER - Diagram depicting the evolutionary
relationships between different species or groups
pg. 3
, Clade - ANSWER - Taxonomic group- single common ancestor and all
descendants
Cladogram - ANSWER - Diagram that shows the evolutionary
relationships among a group of organisms
Order of Hierarchy groups - ANSWER - Domain, Kingdom, Phylum,
Class, Order, Family, Genus, and Species
Prokaryote - ANSWER - A unicellular organism that lacks a nucleus and
membrane bound organelles
Eukaryote - ANSWER - A cell that contains a nucleus and membrane
bound organelles
Autotrophs - ANSWER - Self feeders- through photosynthesis
Heterotrophs - ANSWER - Another- consumes other organisms for
nutrients
Peptidoglycan - ANSWER - Chemical in cell walls thats used to classify
organisms
Gram += purple (positive-purple=pp)
Gram-= red
