Chloroplasts

Noun, The organelles that capture the energy from sunlight and convert it into chemical energy in a process called photosynthesis. Chloroplasts are organelles in which photosynthesis takes place.

Nucleus

Noun, The part of the cell containing DNA and RNA and responsible for growth and reproduction. All eukaryotic cells have a membrane-bound nucleus.

The Levels of Organization

Noun, There are not four, but actually five levels of organization. These are cells, tissues, organs, organ system, and organisms.

Lysosomes

Noun, This is an organelle containing digestive enzymes. lysosomes are vesicles found mainly in animal cells.

Diffusion

Verb, Everything is made of tiny particles which are moving. Particles move from crowded areas to uncrowded areas to less crowded areas which is called diffusion.

Function

Verb, The special, normal, or proper activity of an organ or part. The function of a cell is the activity that the cell performs.

Cell Compartments

Noun, The bubble that forms the Golgi complex's membrane is one example of a vesicle. A vesicle is a small sac that surrounds material to be moved into or out of a cell.

Mitochondria

Noun, The cellular organelles where cellular respiration happens. a mitochondrion is the main powersource of a cell.

Multicellular Organisms

Noun, An organism made up of many cells. Organisms that are made up of many cells are called multicellular.

Ribosomes

Noun, Non-membrane bounded organelles responsible for the making of proteins. Organelles that make proteins are called ribosomes.

Endoplasmc Reticulum

Noun, Series of membrane sent to the cell membrane to the nucleus. Many chemical reactions take place in a cell.

Structure

Noun, The arrangement of parts in an organism. The arrangement of parts in an organism.

Cells

Noun, The basic unit of all living things. Cells in a multicellular organism can be specialized.

Cytoskeleton

A microscopic network of microtubules in the cytoplasm of many living cells that gives the cell shape. The cytoskeleton is a web of proteins in the cytoplasm of some cells.

Unicellular Organization

Adjective, Prokaryotes, most protists, and some kinds of fungi are unicellular. Although some of these organisms live in colonies, they are still unicellular.

Golgi Complex

Noun, A "post office" structure in the cytoplasm of animal cells. The organelle that packages and distributes proteins is called the golgi complex.

Organs

Noun, A fully differentiated structural and functional unit in an animal that is specialized for some particular function. A structure that is made up of two or more tissues working toghether to perform a specific function is called an organ.

Organ System

Noun, A group of organs that work together to perform a specific function. a group of organs working toghether to perform a particular function is called an organ system.

Organisms

Noun, A living thing that has the ability to act or function independently. Anything that can perform life processes by itself is an organism.

Tissues

Noun, A part of an organism consisting of an aggregate of cells having a similar structure and function. a tissue is a group of cells that work toghether to perform a specific job.

Vacuoles

Noun, A saclike structures that store materials such as water, salts, proteins, and carbohydrates. A vacuole is another type of vesicle found in cells.

Unicellular Organisms

Noun, A single-celled organism. Organisms that are made up of one cell are called unicellular.

Cell Wall

Noun, A thin membrane around the cytoplasm of a cell. Plant cells have an outermost structure called a cell wall.

Cell Membrane

Noun, A thin, flexible barrier around a cell; regulates what enters and leaves the cell. All cells have a cell membrane made up of proteins and lipids.

Osmosis

Noun, All living things need water to survive. When water diffuses; the process it is going through is called osmosis.
