The smallest unit that can do all of the activities needed for life.

A living thing; anything that can carry out life processes independently.

prokaryote

A single-celled organism that does not have a nucleus or membrane-bound organelles. 

 The cell has a single circular DNA molecule.

 Examples are archaea and bacteria. 

An organism made up of cells that have a nucleus enclosed by  a membrane. 

Eukoryotes have a nucleus that contains the DNA.

Examples are protists, animals, plants, fungi. 

Not archaea or bacteria.

Single-celled protists.  Move around to find food.

surrounds their food to eat it. 

Example: amoeba

Single-celled protists.  Use photosynthesis to make their own food.  

Have a glassy shell.  Floats in water. 

Cannot move on their own.

dinoflagellates

Single-celled protists.  Move on their own using two flagella that look like whips. 

Perform photosynthesis.  Have a hard shell.

euglenoids

Single-celled protists; 

Gets food in two ways:

 a. photosynthesis

b.  surrounds it  

Uses a flagella to move

fungi

Nongreen eukaryotic organisms;

cannot move around;

uses spores to reproduce;

feeds by breaking down substances in their surroundings

energy

The capacity to do work.

deoxyribonucleic acid

(DNA)

Controls all of the life processes of the cell.

regulation

The process that controls development of cells and growth. 

function

The special, normal, or proper activity of an organ or part.

Its job

structure

The arrangement of how parts in an organism are organized.

Parts of an animal cell

cell membrane

cytoplasm

nucleus

ribosomes

mitochondria

lysosomes

endoplasmic reticulum

Golgi Complex

small vacuoles called vesicles

cell membrane

Found in Plant/Animal cells;

Separates the cell from the surrounding environment;

Allows certain materials, such as gases to move into and out of the cell.

Found in Plant /Animal cells.

Organelle that stores the cell's DNA.

Controls the activities of the cell.

 Found in Plant/Animal cells.

Organelles that make proteins for the cell.

Organelles that have proteins that break down old organelles, wastes, and food.

Found in Plant/Animal cells.

Organelles that break down food to make ATP.

Found in Plants/Animal cells. 

Organelle that transports proteins to the Golgi Complex.

Breaks down toxic material.

Found in Plants/Animals cells.

Organelle that changes proteins so that the protein can function.

Found in Animal cells.

Stores waste, water, food.

 cell membrane

nucleus

cytoplasm

mitochondria

ribosomes

endoplasmic reticulum

Golgi Complex 

 AND

chloroplasts

large central vacuole

cell wall

Organelles that trap light energy from the sun;

Uses light energy, carbon dioxide, and water to make sugars for the plant.

Found only in plants.

Filled with liquid;

Completely surrounded by a membrane;

Can take up a lot of space in the cell;

Helps the cell keep its shape;

Helps keep the plant upright.

Found in plant cells;

Tough and rigid;

Surrounds the cell membrane;

Helps support and protect the plant cell.

tissue

A group of similar cells that perform a common function.

A collection of tissues that carry out a specialized function of the body.

Examples are:  heart and stomach

organ system

A group of organs that work together to perform

body functions.

Example:  Circulatory system

Forms a barrier between you and the external environment.

Can be found in your stomach lining or in your skin.

connect and support other tissues

Blood is a connective tissue.

Helps process information;

Sends information around the body;

The brain is made up of nervous tissue.

muscle tissue

Contracts and relaxes to produce movement;

Muscle tissues in your legs help you walk.
