A rigid supporting layer that surrounds the cell plants and some other organisms

In cells, a large oval organelle that contains the cell's genetic material form of DNA and controls many of the cell's activities

The thick fluid region of a cell located inside the cell membrane or between the cell membrane and nucleus

An organelle that forms a maze of passage ways in which proteins and other materials are carried from 1 part of the cell to another

A thin, flexible barrier that surrounds a cell and controls which substances pass into and out of a cell

A tiny cell structure that carries out a specific function within cell

A small grain-shaped organelle in the cytoplasm of a cell that produces proteins

Rod-shaped organelles that convert energy in food molecules to energy the cell can use to carry out its function

An organelle in a cell that receives proteins and other newly formed materials from endoplasmis reticulum, packages them, and distributes them to other parts of the cell

A sac-like organelle that stores water, food, and other materials

A cell organelle which contains chemicals that breakdown large food particle into smaller ones and that can be used by the rest of the cell

Composing of many cell

An organelle in the cells of plants and some other organisms that captures energy from sunlight and changes it into an energy form that cells can use in making food.

A pure substances that cant be broken down into other substances by chemical or physical means

A substance made of 2 or more elements chemically combined in a specific ratio, or proportion

The genetic material that carries information about an organism and is passed from parent to offspring

The shape of a DNA molecule

A property of cell membranes that allows substances to pass across it, while others cannot.

The movement of dissolved materials across a cell membrane without using a cellular energy

The process by which molecules move from an area of higher concentration to an area of lower concentration

The movement of materials across a cell membrane using cellular energy

A group of organs that work together to perform a major function

The process by which the cell membrane takes particles into the cell by changing shape and engulfing the particles

The process by which the vacuole surrounding particles fuses with the cell membrane, forcing the contents out of the cell.
