Life is made possible by a set of ____ _____ that each serve a purpose - answer
biological molecules
carbohydrates - answer the sugars that act as a source of energy for all living thins
lipids - answer fats, a way for organisms to store energy, they also help with cell
functioning
proteins - answer amino acids and the nutrients the body uses to build and maintain its
cells and tissues
enzymes are important in the ____ system, and help the body break down and extract
energy from different kinds of foods. - answer digestive
nucleic acids – answer DNA and RNA, store an organisms genetic code
both DNA and RNA are made of small molecules called - answer nucleotides
within the nucleus, DNA is packed into units called - answer chromosomes
enzymes are an example of which type of micromolecule? - answerproteins
organisms - answerliving things, such as plants, animals, and bacteria
two basic types of cells - answerProkaryotic and Eukaryotic
prokaryotic cells - answerdo not have a nucleus, and some single-celled organisms like
bacteria and prokaryotes
eukaryotic cells - answercontain a nucleus where the genetic. material is stored and are
found in multicellular organisms
a cell consists of _____ and genetic material (dna) inside a _____ - answercytoplasm
cell membrane
organelles - answerA tiny cell structure that carries out a specific function within the cell
Mitochondria - answerPowerhouse of the cell
, Ribosomes function - answerMakes proteins
vaculoes - answerwhich store water and other molecules
phases of mitosis
"I picked my apples today" - answerprophase, metaphase, anaphase, telophase,
cytokinesis
what happens during prophase - answercell is getting ready to divide by duplicating
DNA
what happens during metaphase of mitosis - answerChromosomes line up in the middle
of the cell
what happens during anaphase of mitosis? - answerpairs begin to split with one
chromosome moving to one side, and the other to the opposite side
what happens during telophase of mitosis - answercell membrane splits and 2 new cells
are formed
after division is completed, the 2 new cells return to a normal resting state which is
called ______ - answerinterphase
mitosis is .... - answercell division
meisos - answerthe formation of reproductive cells called gametes
meiosis is the process that includes ____ cell divisions with phases similar to those of
mitosis - answer2
zygote - answerfertilized egg
in humans, reproductive cells have _____ chromosomes and body cell have _____ -
answer23
46
the chromosomes of a eukaryotic organism are found in the - answernucleus
a distinct difference between plant cell and animal cell is the presence of - answera cell
wall
mitosis produces 2 daughter cells that each have _____ number of chromosomes in the
parent cell - answerthe same
cellular metabolism (respiration) - answeris how cells produce energy
