Cell Basics
All living things are made of one or more cells
What is one part of Cell Theory?
Powerhouse of the cell
What is the mitochondria?
Cells that have a single, circular chromosome
What are prokaryotes?
The stuff that makes up the cell membrane
What is the phospholipid bilayer?
This organelle's DNA is passed directly from the mother to her offspring
What is the mitochondria?
Animal and plant cells
What are types of eukaryotes?
Where the DNA is stored in eukaryotes
What is the nucleus?
Part of a cell's life cycle where growth and DNA replication occur
What is interphase?
When molecules move from areas of high concentration to low concentration
What is diffusion?
23 pairs
How many pairs of chromosomes do humans have?
Cells that have cell walls
What are plant cells?
The material that fills the space in the cell
What is the cytoplasm?
When a DNA mutation occurs and cells divide uncontrollably
What is cancer?
When substances require energy to pass through the cell membrane
What is active transport?
The way our neurons send signals across the body (a type of cell transport)
What is the sodium-potassium pump?
DNA is stored in the nucleoid region, but is open to cytoplasm
What is a prokaryote?
Organelle that makes protein and are found in both prokaryotes and eukaryotes
What are ribosomes?
The stage of mitosis where the daughter chromosomes are being pulled to either end of the cell
What is anaphase?
A major characteristic of the cell membrane that allows some substances through
What is selective permeability?
One of few types of contagious cancer
What are facial tumors in tasmanian devils?
The basic unit of DNA for replication and cell division
What are chromosomes?
Organelle involved in photosynthesis
What are chloroplasts?
The process where the circular strand of DNA is replicated and the cell pulls itself into two daughter cells
What is binary fission in prokaryotes?
When the cell engulfs the substance and forms a vesicle to bring it inside, a type of active transport
What is endocytosis?
The estimated amount of time it takes to replace all cells in the human body
What is 7 years?
