Photosynthesis & Cellular Respiration Meiosis DNA & RNA Protein Synthesis Mitosis

Organisms that must consume other organisms for energy

HETEROTROPHS

This green pigment, found in plant cells has the job of absorbing light energy

CHLOROPHYLL

Cellular respiration produces three things: 1) CO2 2) H2O 3) ?

ATP (cellular energy)

The ultimate original source of energy on earth

THE SUN

When there is a lack of oxygen in a cell, this process occurs

FERMENTATION

A cell that has two copies of each chromosome (are in pairs) and is symbolized as 2n

DIPLOID

If an organism produces haploid gametes with 12 chromosomes, how many chromosomes would be in one of its BODY cells?

24

Method by which bacteria reproduce

BINARY FISSION

Cell #3 below, whose chromatids are lined up in the middle of the cell is in which phase of mitosis?

METAPHASE

A cell plate forms when this type of cell undergoes cytokinesis

PLANT CELL

Reproductive cells (gametes) are said to have only one set of chromosomes or are referred to as this

HAPLOID

In Anaphase I of meiosis homologous chromosomes are separated. In Anaphase II these are separated.

SISTER CHROMATIDS

Which illustration above depicts meiosis? A B

A

This is when homologous chromosomes exchange corresponding segments of chromosomes

CROSSING OVER

If chromosomes fail to separate properly during meiosis, gametes might receive too many or too few chromosomes. What is this error called?

NONDISJUNCTION

The primary job of this molecule is to store and transmit genetic info

DNA

The monomer unit of nucleic acids

NUCLEOTIDE

The three parts of a DNA nucleotide are: 1) phosphate group 2) nitrogen containing base 3) ?

DEOXYRIBOSE SUGAR

RNA differs from DNA in that it: 1) sometimes single stranded 2) contains ribose sugar 3) contains the base ______

URACIL

This type of RNA has the job of carrying amino acids to the ribosomes

tRNA

The two stages of protein synthesis are: 1) transcription 2) ?

TRANSLATION

Where does transcription take place?

NUCLEUS

During transcription, what molecule gets produced?

RNA

mRNA is read as triplets, each one coding for a particular amino acid. These triplets are called

CODONS

mRNA gets translated into a chain of amino acids at these cell parts

RIBOSOMES

FINAL JEOPARDY Put the numbers of the cells in order and name the phase for each

FINAL JEOPARDY ANSWER 2 – Interphase 4 – Prophase 3 – Metaphase 1 – Anaphase 5 - Telophase
