What is binary fission? - ANSWER - A form of asexual reproduction in which the parent divides into two identical halves.
What is cytokinesis? - ANSWER - The division of cytoplasm into two identical daughter cells, which occurs during the telophase stage of mitosis.
What is a haploid cell? - ANSWER - A cell that contains one set of chromosomes
What is a diploid cell? - ANSWER - A cell that contains two sets of chromosomes
What is chromatin? - ANSWER - The substance of which eukaryotic chromosomes are composed, consisting of mostly proteins, DNA, and RNA.
What is a centriole? - ANSWER - a cylindrical organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division.
What is a chromosome? - ANSWER - A structure carrying genes is a linear sequence, found in the nucleus, consisting of DNA and protein. 1 / 3

What is DNA? - ANSWER - A double-stranded, helical nucleic acid molecule capable of replicating and determining the inherited structure of a cell's proteins. It makes up the genetic material of most living organisms and plays a role in determining heredity.
What is RNA? - ANSWER - A single-stranded nucleic acid molecule involved in protein synthesis. It is responsible for carrying the genetic code transcribed for DNA to specialized sites within the cell where the information is translated into protein composition.
Where are the cell's chromosomes stored? - ANSWER - The nucleus.
Which organelle is particularly important for the synthesis, folding, modification, and transport of proteins within the cell? - ANSWER - The endoplasmic reticulum.
Which of the following has ribosomes attached to its surface? - ANSWER - The rough endoplasmic reticulum.
After transporting and modifying proteins and lipids, the Golgi apparatus
packages them into: - ANSWER - Vesicles.
Which organelle acts as an assembly line where proteins are synthesized from RNA? - ANSWER - Ribosomes.
Which organelle generates energy for the cell? - ANSWER - Mitochondria.

pg. 3 Which of the following organelles could be described as 'a compartment filled with water containing inorganic and organic molecules'? - ANSWER - Vacuole.
Carbon dioxide and oxygen move across the plasma membrane by the
process of: - ANSWER - Diffusion.
What is the name for the process whereby the membrane of a vesicle fuses with the plasma membrane, allowing its contents to be released from the cell? - ANSWER - Exocytosis.
What is a nucleotide? - ANSWER - A nucleotide is the basic building block of nucleic acids. RNA and DNA are polymers made of long chains of nucleotides. A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen- containing base.
What is transcription? - ANSWER - Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). ... This complex initiate transcription, and the RNA polymerase begins mRNA synthesis by matching complementary bases to the original DNA strand.
What is translation? - ANSWER - Translation is the process by which a protein is synthesized from the information contained in a molecule of messenger RNA (mRNA). Translation occurs in a structure called the ribosome, which is a factory for the synthesis of proteins
What is endocytosis and exocytosis? - ANSWER - Endocytosis is the process of capturing a substance or particle from outside the cell by engulfing it with the cell membrane, and bringing it into the cell. Exocytosis
