Periodic Table of Elements

A chart that organizes all known elements by atomic number.

The attraction of two hydrogen atoms, one with a negative charge and the other with a positive charge.

A material of two or more substances that are physically combined.

The substance that dissolves the solute.

Rates solutions from 0 - 14 by the amount of hydrogen in them. Water is neutral (7).

Acids and are positively charged (+).

Bases and are negatively charged (-).

Used by organisms to maintain homeostasis and keep a pH balance.

Cells: The basic unit of life. All organisms are cells or are made of cells.

Multicellular organisms

Multicellular: Organisms that consist of many cells.

Unicellular organisms

Unicellular: Organisms that consist of 1 cell.

Microscope discovery of cells

Robert Hooke: Used a microscope to look at cork cells. He is credited for discovering cells.

Microscope observation of pond water

Antoni Van Leeuwenhoek: Used a microscope to look at tiny organisms in pond water.

Cell Theory: 1. All living things are made up of one or more cells. 2. Cells are the basic units of structure and function in living things. 3. All living cells come from existing cells.

Prokaryotic organisms

Prokaryotic: Organisms with very little organization of the materials inside their cell membrane and very few specific cell structures.

Eukaryotic: Organisms with more complex cells made up of organelles.

Organelles: Structures inside a cell that perform a function.

Function of the nucleus

Nucleus: Command center of animal and plant cells by controlling the cell.

Cell Membrane: Porous flexible structure allows some things to pass, keeps other things out, and keeps the inside fluid part of the cell.

Cell Wall: Thick wall of protection outside of a plant cell.

Function of chloroplasts

Chloroplasts: Organelle that produces food for the plant cell through the process of photosynthesis.

Photosynthesis: Process by which organisms that have chloroplasts use light energy, carbon dioxide, and water to make sugar.

Mitosis: The process of cells dividing to make new cells.

Bacteria: Single celled organisms that reproduce asexually. Are known for being decomposers and starting infections.

Proteins that make up a genetic code. DNA is passed from parents to offspring.

Bases within a genetic code (A, C, G, T).

Molecules that combine to form proteins.

Genetic information bundled together into DNA.

The biological form of inheritance.

Studied pea plants and their passing of traits in each generation.

The traits that show up more often.

The traits that do not show up often.

Simple chart used to show passing of traits.

Theory of genetic changes over long periods of time.

Studied finches on the Galapagos islands and noticed similar traits of different species.
