6 PARTS OF CELL THEORY

Back 1

1.Basic unit of life

2.All organisms are composed of cells

3.Cells arise from pre-existing cells

4.Cells contain DNA that is passed on during cells division

5.Flow of energy in organisms is through cells

6.All cells have same basic chemical structure

Front 2

CELLULAR REPRODUCTION

Back 2

Body grows as you add more cells. You produce more cells when you sleep. Mitosis is important during Cellular Reproduction.

Front 3

TWO TYPES OF CELLS

Back 3

Prokaryotic: cell without nucleus and complex organelles

Eukaryotic: with nucleus and complex organelle system

Front 4

ORGANELLES

Back 4

a tiny cell structure that carries out a specific function within the cell. Each organelle is specialized and does its own job. They all work together in function to help the cells.

Front 5

CYTOPLASM

Back 5

region between cell membrane and nucleus. all organelles are covered in this jelly like substance.

Front 6

CELL MEMBRANE

Back 6

cell structure that controls which substances can enter and leave the cell

Front 7

NUCLEUS

Back 7

cell structure that contains nucleic acids , the chemical instructions that direct the cells activities

Front 8

ENDOPLASMIC RETICULIUM

Back 8

a cell structure that forms a maze of passageways in which proteins and other materials are carried from one part of the cell to another.

Front 9

RIBOSOME

Back 9

a small grain like structure in the cytoplasm of a cell where proteins are made, proteins are the building materials for the organism.

Front 10

GOLGI BODY

Back 10

a structure in a cell that receives proteins and other newly formed materials from the endoplasmic reticulum, packages them, and distributes them to other parts of the cell.

Front 11

MITOCHONDRIA

Back 11

rod shaped cell structures that concert energy in food molecules to energy the cell can use to carry out its functions.

Front 12

VACOLE

Back 12

a sac round cell structure containing chemicals that break down large food particles into smaller ones

Front 13

LYSOSOME

Back 13

a small round cell structure containing chemicals that break down large food particles into smaller ones

Front 14

CELL WALL

Back 14

A rigid layer of non living material that surrounds the cells of plants and helps the organism stand up right. Made of carbohydrate cellulose.

Front 15

VACOLE

Back 15

Sack in a cell that acts as a storage area. Stores water in plants and is usually very big (for a plant that is)

Front 16

CHLOROPLAST

Back 16

A structure in the cells of plants and some other organisms that captures energy from sunlight and uses it to produce food. Contains chlorophyll which allows plants to make their own food. Energy is used (sun) in photsynthesis.

Front 17

CELL

Back 17

Basic unit of life

Front 18

ROBERT HOOKE

Back 18

first person to see cells . He looked at cork and saw "small rooms"

Front 19

PHOTOSYNTHESIS

Back 19

the process in which plants and some other organisms capture the energy in light and use it to make food. takes place in chloroplast.

Front 20

CELLULAR RESPIRATION

Back 20

the process by which cells break down simple food molecules to release the energy they contain. takes place in mitochondria.

Front 21

TISSUE

Back 21

a group of similar cells working together ( muscle, blood, nerve, epithelial, connective)

Front 22

ORGAN

Back 22

groups of tissues working together to preform a specific function ( heart, stomach, brain)

Front 23

ORGANISM

Back 23

a living thing (HOMO sapien)

Front 24

ORGAN SYSTEM

Back 24

a group of related organs preforming a vital life function (lung system)

Front 25

ATOMS

Back 25

basic unit of chemical element

Front 26

MOLECULE

Back 26

atoms bonded together that represent the smallest fundimental unit of chemical compound.
