• Cell Membrane

• Nucleus

• Golgi apparatus

Structure that contains the cell's genetic material in the form of DNA

• Vacuole

• Nucleolus

• Nucleus

• Ribosome

Cell organelle that converts the chemical energy stored in food into compounds that are more convenient for the cell to use

• Chloroplast

• Mitochondria

• Golgi apparatus

• Endoplasmic reticulum

Which of the following are the reactants of photosynthesis?

• O₂ + Glucose(sugar)

• CO₂ + O₂

• CO₂ + Glucose(sugar)

• CO₂ + H₂O

Which of the following are the products of photosynthesis?

• O₂ + Glucose(sugar)

• CO₂ + O₂

• CO₂ + Glucose(sugar)

• CO₂ + H₂O

Which of the following answer choices describes the relationship between asexual sexual reproduction and mitosis?

• Mitosis undergoes the process of asexual reproduction resulting in 2 identical diploid (46 chromosomes) cells.

• Mitosis undergoes the process of sexual reproduction resulting in 4 genetically different haploid (23 chromosomes) cells.

• Mitosis undergoes the process of asexual reproduction resulting in 2 identical haploid (23 chromosomes) cells.

• Mitosis undergoes the process of sexual reproduction resulting in 4 genetically different diploid (46 chromosomes) cells.

Carefully read all of the answer choices. Then, correctly match the the phase of Mitosis to its description.

• Spindle fibers attached to the centromere of chromosomes move them to the middle of the cell.

• Metaphase

• Nuclear envelope reforms and the cytoplasm breaks apart, splitting the cells into 2.

• Prophase

• Spindle fibers pull the sister chromatids away to each side of the cell.

• Telophase/Cytokinesis

• Chromosomes are visible, nuclear envelope disappears, spindle fibers start to form.

• Anaphase

Which process is represented by #10?

• DNA Replication

• Transcription

• Translation

• Transfiguration

Select the mRNA and amino acid sequence produced from the DNA sequence below: (Hint: the chart used mRNA codons, not DNA)

DNA: TAC-ATG-ACT

• ATG-TAC-TGA

  Ala-Thr-Leu

• AUG-UAC-ACA

  Met-Tyr-Thr

• AUC-UAC-UGA

  Ile-Tyr-Stop

• AUG-UAC-UGA

  Met-Tyr-Stop

Read all answer choices. Select the correct chemical equation for the processes of photosynthesis and cellular respiration.

• Photosynthesis: C6H1206 + O2 -> H2O + Light Energy + CO2

  Cellular Respiration: CO2 + H2O + LIGHT ENERGY -> O2 + C6H12O6

• Photosynthesis: LIGHT ENERGY + CO2 + H2O -> O2 + C6H12O6

  Cellular Respiration: C6H12O6 + O2 -> ATP + CO2 + H2O

• Photosynthesis: LIGHT ENERGY + H2O + O2 -> CO2 + C6H12O6 Cellular Respiration: CO2+C6H12O6 -> O2 + H2O + ATP

• Photosynthesis: LIGHT ENERGY + H2O + CO2 -> ATP + CO2

  Cellular Respiration: C6H12O6 + ATP -> O2 + H2O
