Week 2
The process by which cells divide to form two identical daughter cells.
What is mitosis?
Thin - flexible - double layer of phospholipids
What is the Cell membrane?
The site of protein synthesis.
What is the ribosome?
The concentration of particles in a solution.
What is osmotic pressure?
High to low - moves water - depends on solute concentration
What is osmosis?
High to low concentration - no energy - diffusion
What is passive transport?
Functions in cell division.
What are centrioles?
contains the genetic material (DNA)
What is the nucleus?
Gel like substance that fills the interior of the cell.
What is cytoplasm?
equal solutes on either side of a membrane
What is isotonic?
Extensions from the cell
23 chromosomes
What are the sperm and ovum cells?
oxygen + glucose
What are the requirements to make ATP?
What are the end products of cellular respiration?
The process of cell division by which the egg and sperm cells are formed.
What is meiosis?
What is differentiation?
What are enzymes?
Specialized diffusion - needs a carrier molecule
What is facilitated diffusion?
genetic material - directs cell activities - replicates before it divides - instructions for building body proteins
What is the function of DNA?
Low to high concentration - requires energy - carrier molecule.
What is active transport?
Contains the enzymes that produce the reactions in energy production (ATP)
What is the mitochondria?
hydrostatic pressure -moves molecules from high to low concentration
What is Filtration?
transcription - translation
What are processes of protein synthesis?
moves molecules from low to high concentration - requires energy
What are parts of the Cell?
