Looking Inside Cells

Front 1

Organelle

Back 1

-Tiny cells structures
-Carry out specific functions within the cell.

Front 2

Cell Wall

Back 2

-Rigid layer of nonliving material that surrounds the cells of plants and some other organisms.
-The animal cells in contrast do not have cell walls.
-The cell wall is made of a strong material called Cellulose.
-The cell wall is tough but still many other materials including water and oxygen could pass threw easily.

Front 3

Cell Membrane

Back 3

-All cells have cell membranes.
-The cell membrane is locateed just inside the cell wall.
- In other cells, the cell membrane is formed outside the cell boundary from its enviroment.

Front 4

Nucleus

Back 4

-Cell's control center
-The chromatin ih the nucleus contains instructions for carrying out the cell's activities

Front 5

Nuclear Envelope

Back 5

-The nucleus is surrounded by a membrane called the nuclear envelope.
-It protects the nucleus
-material pass in and out of the nucleus through pores in the nuclear envelope

Front 6

Chromatin

Back 6

The chromatin is the thin strands that float directly ahead in the nucleus
-Contains genetic material, the instructions for directing the cell's function

Front 7

Nucleolus

Back 7

-Nucleosus is where the ribosomes are made.
-ribosomes are the organells where proteins are produced
-Proteins are important chemicals in cells

Front 8

Cytoplasm

Back 8

Cytoplasm is the region betwwen the cell membrane and the nucleus.
-It includes a gel-like fluid in which many different organelles are found

Front 9

Mithochondria

Back 9

-Mithochondria are known as the "powerhouses" of the cell because they convert energy in food molecules to the energy cell can use to carry out its functions

Front 10

Endoplasmic Reticulum

Back 10

-The endoplasmic reticulum's passageways carry proteins and other materials from one part of the cell to another

Front 11

Ribosome

Back 11

-Ribosome were attached to some surfaces of the endoplasmic reticulum.
-Small and grain-like bodys.
-Other ribosomes float in the cytoplasm.
-Ribosomes function as factories to produce proteins
-Some newly made proteins are released through the wall of the endoplasmic reticulum, the proteins will be transported to the Golgi bodys.

Front 12

Golgi body

Back 12

-Golgi bodies recieve protiens and other newly formed materials from the endoplasmic reticulum, package them, and distribute them to other parts of the cell
-The golgi bodies also release materials outside the cell.

Front 13

Chloroplast

Back 13

-Only plant cells have Chloroplast
-Chloroplast capture energy from sunlight and use it to produce food for the cell.

Front 14

Vacuoles

Back 14

-Varuoles are the storage areas in cells.

Front 15

Lysosomes

Back 15

-lysosomes are small, round structures containing chemicals that break down certain materials in the cell

Front 16

Specialized Cells

Back 16

-In many-celled organisms, cells are often organized into tissues, organs, and organ systems

Front 17

Tissue

Back 17

-A tissue is a group of similar cells that work together to proform a specific function.

Front 18

Organ

Back 18

-An organ is made of different kinds of tissues that function together

Front 19

Organ System

Back 19

-An organ System is a group of organs that work toghether to perform a major function

Front 20

Bacterial Cell

Back 20

-While a bacterial cell does have a cell wall and a cell membrane, it does not contain a nucleus.
-The bacterial cell's genetic material, which looks like a thick, tangled string, is found in the cytoplasm.
