A parent cell forms a new cell by producing a small bump on its side which grows into the new cell

A process of cell reproduction whereby a single cell splits apart to form two new identical cells; cell division

Cells that have a cell embrane, cytoplasm, and a nucleus

Simple organisms that consist of one cell. They are a type of prokaryote cells (no nucleus).

The basic unit of all living things.

The thin-layer outer structure of each cell that completely surrounds the cell and holds the other contents of the cell within it.

A non-living chemical produced by the plant's cells. It surrounds the cell outside the cell membrane. It is harder than the cell membrane.

The fluid material (mainly water) within the cell membrane that does not include the nucleus.

The type of cell that contains three basic parts: the cell membrane, the cytoplasm, and the nucleus.

Contains more than one cell, usually many cells.

The command center that controls the life and activity of the cell. It is located within the cytoplasm of the cell.

The type of cell that contains only two basic parts: the cell membrane and protoplasm. It does not have a nucleus. Bacteria are an example of this cell.

The inner fluid material within the cell membrane.

One-celled. Living things that have only one cell.

The long strands of material within the nucleus made up of DNA, RNA, and other proteins

The orderly strands of chromatin that form when a cell is going to reproduce.

Abbreviation for Deoxyribonucleic Acid. A very large, complex molecule that forms a double-helix shape and is contained in the chromatin of cells.

Part of the DNA within the cell. Genes are like recipes for making specific types of proteins in the cell.

An outer, double-membrane covering for the material within the nucleus.

A small part within the nucleus that is very condensed chromatin and consists mainly of RNA and other proteins.

Tiny sub-parts of material within the cytoplasm of a cell that produce proteins, energy, or perform a specialty function.

A molecule that forms most of the material for the cell membrane and the nuclear membrane. It forms a double layer to make the cell membrane and four layers on the nuclear membrane.

Large, complex molecules made up of smaller units called amino acids. All proteins contain carbon, hydrogen, nitrogen, and oxygen. They may also contain other elements. Proteins are important in the life and activities of cells

Abbreviation for Ribonucleic Acid. A complex molecule similar to DNA that plays an important role in making the proteins within cells.

A substance that forms the walls of plant cells.

The green pigment in a plant cell chloroplast that gives the plant a green color.

An organelle found in the cytoplasm of plant cells that contain chlorophyll and is involved in energy production in the cell.

A very important process in plants that takes energy from sunlight and the chlorophyll in the plant and forms oxygen and sugars from carbon dioxide and water.

The outside layers of cells which cover plants.

A layer of cells that form the skin and the linings of various inner organs and glands.

A group of similar cells connected together that perform similar work.

The capacity to do work. Both plants and animals need energy to do their work.

A process by which cells combine oxygen with food and give off carbon dioxide and energy.
