Term
What is DNA?
Definition
Information to make a protein
Term
A (Adenine) pairs with?
Definition
T (Thymine)
Term
C (Cytosine) pairs with?
Definition
G (guanine)
Term
What does gene mean?
Definition
the order of bases determined to what protein gets made.
Term
Why do cells go through cell division?
Definition
For growth, repair, and reproduction
Term
What organelle allows diffusion and osmosis in cells?
Definition
Cell Membrane
Term
Why do molecules move in diffusion and osmosis?
Definition
molecules want to spread out on their own
Term
Photosynthesis
Definition
is a process where some producers (mainly plants) make food (transforms energy)
Term
Cellular Respiration
Definition
A process in eukaryotes that uses oxygen and food to release energy(transforms energy)
Term
Fermentation
Definition
a process in all cells that turns food into energy without oxygen.
Term
Diffusion
Definition
a process anywhere where molecules move from an area of high concentration to areas of low concentration.
Term
Osmosis
Definition
a process anywhere where water molecules move from and area of high concentration across a membrane.
Term
active transport
Definition
a process in cells where molecules move from low concentration to high concentration using energy.
Term
Mitosis
Definition
a process in eukaryotes (have a nucleus that moves chromosomes(DNA) so each new cell get the right DNA
Term
DNA Replication
Definition
a process in a cell that makes a copy of DNA
Term
Endocytosis (Enter)
Definition
The cell surrounds and pulls a particle into the cell
Term
Exocytosis (Exit)
Definition
The cell pushes a particle out of the cell.
Term
Why do cells go through mitosis?
Definition
In order to create it's DNA and reproduce
Term
What happens in interphase?
Definition
Grows full size, produces organelles, goes through replication process (chromosomes), prepares to divide.
Term
What happens in Prophase?
Definition
Cell's nucleus divides into two new nuclei and one set of DNA is distributed into each daughter cell.
Term
What happens in Metaphase?
Definition
Each chromosome attaches to a spindle fiber at its centromere (missing the nucleus)
Term
What happens in Anaphase?
Definition
Centromere of each chromosome splits, pulling the chromoatids apart.
Term
What happens in Telophase?
Definition
Nucleus is coming back (around chromosomes) Cell is starting to split in two.
Term
What happens in cytokinesis?
Definition
Cell splits in two daughter cells cytoplasm is divided between the two cells.
Term
What is Prophase beginning to lose and metaphase doesn't have?
Definition
A nucleus
Term
What is the process of making traits?
Definition
DNA sends info to ribisomes and it makes proteins. (Melanin) depending on the gene it makes the trait.
Term
What is DNA made of?
Definition
nucleotides
Term
What are nucleotides made of?
Definition
nitrogen base
Term
What shape is DNA?
Definition
Double Helix (twisting ladder) (two bases)
Term
Molecule
Definition
a small unit; a part of something (water molecules make up water)
Term
Concentration
Definition
how packed molecules are together (can be high or low)
Term
What kind of materials do cells need to take in?
Definition
food (glucose), water
Term
What kind of materials do cells want to get rid of?
Definition
Carbon Dioxide? Energy???? I don't know!
Term
What are Endocytosis and Exocytosis examples of?
Definition
Active Transport
Term
What are diffusion and osmosis examples of?
Definition
Passive Transport
