Processes I
Nearly all living things obtain energy from this
What is the Sun?
Period before cell division where the cell grows, makes a copy of DNA and prepares to divide
What is interphase?
These make their own food from the sun
What is an autotroph?
DNA short for
What is deoxyribonucleic acid?
Genetic material that carries info about an organism from one generation to the next
What is DNA?
Process by which a cell captures energy in sunlight and uses it to make food
What is photosynthesis?
All chromosomes are pulled to the center of the cell
What is metaphase?
Regular sequence of growth and division that cells undergo
What is the cell cycle?
These obtain energy from feeding on other organisms
What are heterotrophs?
Chromatin bundles up to form chromosomes and nucleolus disappears
What is prophase?
Two new nuclei are formed
What is telophase?
Stage during which the cell's nucleus divides into two new nuclei - one copy of the DNA is distributed into each of the two daughter cells
What is mitosis?
During photosynthesis, carbon dioxide and water are converted into oxygen and these molecules
What are sugars?
Process by which cells obtain energy from glucose by breaking down simple food molecules
What is cellular respiration?
Cytoplasm divides and the organelles are distributed into each of the two new cells
What is cytokinesis?
DNA is found in this organelle
What is the nucleus?
In cellular respiration, sugar and oxygen are converted into water and these molecules
What is carbon dioxide?
Split chromatids pulled to opposite ends of the cell
Prophase, metaphase, anaphase, telophase
What are the 4 stages of mitosis?
The shape of the DNA molecule
What is the double helix?
The 3 components of the nucleotide
What are 5-carbon sugar, phosphate group and nitrogen base?
The number of nitrogen bases
What is 4?
The motion of the DNA molecule while it is replicating
What is unzip?
Base that pairs with Adenine
What is thymine?
base that pairs with guanine
What is cytosine?
