____ results when particles move from high concentration to low concentration
Diffusion
A large or charged particle using a protein to help it cross a membrane in order to move from high concentration to low concentration
Facilitated diffusion
The movement of water from areas of low solute concentration to high solute concentration
Osmosis
Cellular structures that perform the necessary functions of a cell
Organelles
A membrane that allowed some particles to pass through but prevents other is ____
Semi-permeable
_____ is when particle movement requires the input of cellular energy
Active Transport
The process in mitochondria that generates ATP from foods
Cell respiration
The process in the chloroplast that generates glucose using light energy
Photosynthesis
A series of chemical reactions that brings uses CO2, electrons, and ATP to make glucose
Calvin Cycle
A series of chemical reactions that release cO2 and high energy electrons
Citric Acid Cycle
The first step of mitosis:
When chromosomes condense and the nucleus breaks down
Prophase
The second step of mitosis:
When chromosomes align at the equator of the cell
Metaphase
The third step of mitosis:
When chromatids aperste and move to opposite ends of the cell
Anaphase
The fourth step of mitosis:
When a cleavage furrow forms and the cell stars to split in two
Telophase
A model that describes the plasma membrane of a cell
The Fluid Mosaic Model
A group of single cell organisms that lack membrane bound organelles
Prokaryotes
A group of organisms that have a nucleus as well as other membrane bound organelles
Eukaryotes
The process of cell division among eukaryotic organisms
Mitosis
A protective cellular structure around the plasma membrane
Cell wall
A ____ is the organelle that performs photosynthesis
Chloroplast
_____ are the organelles that perform cell respiration
Mitochondria
The organelles that build proteins based on instructions from the DNA
Ribosomes
All living things are made of cells, cells are the basic unit of living things, and new cells come from existing cells
Cell theory
An organism that can produce its own food for energy
Autotroph
An organism that must get its energy from other organisms
Heterotroph
