What is a cell?
Control center of cell
What is the nucleus?
The ultimate source of energy
What is the sun?
Movement of particles from higher to lower concentration.
What is diffusion?
Cell division process in which each daughter cell receives an identical copy of parent's chromosomes.
What is mitosis?
Robert Hooke
Who was the first person to see cells?
A thick outer layer of cellulose that gives plant cells added support and strength
What is a cell wall?
Process allowing cells to convert energy to a useable form.
What is cellular respiration?

What is an organelle?
Molecule that carries energy in the cell
What is ATP?
Transport requiring the use of energy.
What is active transport?
Chemical carrying information in chromosomes.
What is DNA?

What are mitochondria?
Speed up reactions a million times faster or more
What are enzymes?
Membranes that allow some substances to pass through, while blocking others.
What are selectiely permeable membranes?
Cell division process in which bacteria splits into two identical daughter cells.

What is: all living things are coposed of one or more cells; cell is the basic unit of ife and all chemical reactions occur within it; all cells come from other cells?
A watery fluid that surrounds everything in the cell.
What is cytoplasm?
A series of chemical reactions that breaks down or makes materials that the cell needs
What is a metabolic pathway?
The pressure created by diffusion of water into a plant cell.
What is turgor pressure?
Cell division process that reduces the number of chromosomes to 1/2 the original amount
What is meiosis?
