Bacteria

 smallest organisms on earth

Cell Membrane

 flexible structure that holds the cell together (walls of the bakery)

Cell Wall

 supports and protects the cell

Cytoplasm

 the gelatin like substance that fills the inside of the cell

Organelle

 specialized cell parts that can more around in the cytoplasm and perform activities necessary for life

food, water and other substances are stored in these balloon like organelles in the cytoplasm

Mitochondria

 energy producing area, cellular respiration occurs here

Photosynthesis

 process that allows plants, algaes, and many types of bacteria to make food; usually occurs in leaf cells

Chloroplast

  green organelles within the leaf cells

Tissue

 groups of similar cells that all do the same sort of work

Organ

 different types of tissues working together 

Organ System

a group of organs that work together (digestive system, respiratory system, circulatory system, reproductive system, and nervous system)

Chlorophyll

 is a green pigmnd in almost all plants, algae, and cyanobacteria.ent fou

Nucleolus

 is a non-membrane bound structure composed of proteins and nucleic acids found within the nucleus.

Ribosomes

 are the components of cells that make proteins from all amino acids.

Lysosome

are cellular organelles which contain acid hydrolase enzymes to break up waste materials and cellular debris.

Cell Theory

 refers to the idea that cells are the basic unit of structure in every living thing.
