Cells

QuestionAnswer
What is a cell? The cell is the basic unit of life.
What is the cellular membrane? A protective, semi-permeable, outer layer of the cell.
What is cytoplasm? The watery medium in which all the organelles float inside the cell.
What are ribosomes? Little grains floating around inside the cell involved in protein production.
The nucleus contains what? Our DNA with all our genetic information.
Our genetic information is found on what? 23 paired structures called chromosomes.
the nucleus is surrounded by what? The nuclear membrane.
What is the rough endoplasmic reticulum? A series of folded membrane pathways spotted with ribosomes. Together they make new proteins and membranes.
What is the smooth endoplasmic reticulum? It forms containers called transport vesicles that are used to move things around inside the cell.
What is the Golgi apparatus/body? Packages things to be transported out and around the cell.
What are lysosomes? Vesicles with digestive enzymes inside to break down the things the cell no longer need.
What is the mitochondria? Have a double membrane with finger-like projections and break down sugars to make energy for the cell.
What is an example of an atom? Hydrogen, Boron, Copper, Oxygen.
What is an example of a molecule? Water (H2O), Carbon dioxide (CO2), Glucose (C6 H12 O6)
What is an example of a macromolecule? Glucose in starch, protein.
What is an example of an organelle? Nucleus, mitochondria, cytoplasm.
What is an example of a cell? Ova (egg cell), sperm cell, skin cell.
What is an example of a tissue? Connective tissue, nervous tissue, epithelial tissue.
What is an example of an organ? Stomach, liver, pancreas, brain.
What is an example of a system? Respiratory, digestive, immunitary, lymphatic.
What is an example of an organism? Human.
What is DNA? Deoxyribonucleic acid.
What is the shape of DNA? Double helix.
What are the 4 nucleotide bases? Adenine (A), Thymine (T), Cytosine (C), Guanine (G).
Which nucleotide bases bond with each other? Adenine (A) binds with Thymine (T). Cytosine (C) binds with Guanine (G).
How many chromosomes do you inherit from each parent? 23 for a total of 46 chromosomes.
What is your genome? The whole sequence of your DNA.
What are alleles? The 2 versions of each trait that you get from each of your parents.
What are the 2 kinds of cell division? Mitosis and Meiosis.
What is mitosis? When a cell grows, replicates its DNA, and divides to form two daughter cell that are identical to the parent cell.
What is meiosis? When a cell divides in order to create 4 daughter cells with half the DNA of the parent cell.
How many times does a cell divide during mitosis? Once.
How many times does a cell divide during meiosis? Twice.
What happens during Prophase 1? The duplicated homologous chromosomes pair, and crossing-over (the physical exchange of chromosome parts) occurs.
