nucleus
|
control cell activities
produce ribosomes it contains the cell hereditary information (DNA) |
|
cell membrane
|
it gives the cell shape and holds the cytoplasm
separates cell contents from the environment the cell membrane consists of a double layer of phospholipids interspersed with variety of other molecules. |
|
chromosomes
|
it carry hereditary information ( DNA )
|
|
ribosomes
|
where the proteins are made
|
|
mitochondria
|
release energy from food
produces energy through cellular respiration |
|
vacuole
|
store substances
|
|
lysosomes
|
destroy worn out parts and get rid of bacteria
contains digestive enzymes that breakdown food and old organelles. |
|
chloroplast
|
it makes food for plants
|
|
cell wall
|
the thick outer in the plant it's covering, protecting and supporting the cell
|
|
ER endoplasmic reticulum
|
moves materials within cell
|
|
cytoplasm
|
it's where the cells do most of it's chemical reaction
gel like fluid that holds the organelles. where all chemicals take place it's clear color |
|
cyto skeleton
|
skeleton of the cell, supports cell's structure.helps in intracellular transport and cell movement
|
|
Golgi apparatus
|
synthesis, packages and releases concentrate proteins or lipids

Teodor Shwam
|
he was a German scientist. In 1839 he concluded that all animals were made of cell
|
|
Robert Hooke
|
In 1665 after observing a dead cork cells under the microscope. He used the word "cell" to describe the basic unit of all living things.
|
|
Prokaryotic Cells
|
cells without a nucleus and with out cell membrane
ex.bacteria do not contain individual cell parts. |
|
The Cell Theory
|
1_ All living things are made of cells
2_ Cells are the basic unit of structure and functions in all living things 3_ Cell can come only from another cell 4_ Cell need and use energy 5_ Cell contain DNA 6_ The cell of each species are chemically similar |
|
what is the names of the Oraganells that they only found in plants?
|
1_ Cell Wall
2_ Chloroplasts |
|
Eukaryotic Cells
|
Cells that contain a nucleus and membrane
ex. animals , plants, fungi, and protist cells |
|
Mattias Schleidan
|
He was a German botanist. In 1838 he concluded that all plants are made of cells.
|
|
Golgi Body
|
it packages and store chemicals
|
|
Why when viewing an objects through a lens they appear upside down?
|
because the light go the lens and then it bends ( the light bends ) and it will look upside down.
|
|
Cellular Respiration
|
process by which a cell releases energy from food in the mitochondria.
|
|
Ingestion
|
process of taking in food
|
|
digestion
|
process of breaking down food so that it can be used by living things
the chemical breakdown of organic and inorganic molecules into smaller parts |
|
transpor
|
process of moving nutrients and wasted in a living thing.
moving materials around the cell organism. |
|
Excretion
|
process of getting rid of wastes
|
|
What information must be included on all microscope drawing?
|
The information that is included on all microscope drawing is magnification power.
|
|
Anton Van Leeuwenhoek
|
He was a Dutch businessman and a lens maker
In 1674 he was the first person to see microscope living thing in a drop of pond water. |
|
Rudolf Virchow
|
In 1855 Virchow proposed that all cells come from other cells.
|
|
Explain how to use the microscope?
|
1_ use the coarse adjustment to raise the body tube.
2_ adjust the diaphragm so that you can see a bright light through the eyepiece 3_ place the slide on the stage, and be sure to center it over the hole in the stage and secure it with the stage clip. 4_ Turn the nose piece to click the scanning objective lens into place. 5_using the coarse adjustment Knob, slowly lower the lens and focus on the specimen being viewed. Be Sure not to touch the slide or objects within lens. 6_When using the light power lens, use only fine adjustment Knob. 7_ Move the slide on the stage with very small movements to view other parts of it. you may need to refocus using the fine adjustment. |
|
Describe how to properly carry microscope?
|
you hold it firmly by "Arm" and "Base" when walking with it, it should be held near your chest.
|
|
What is the difference between cell parts and a molecules?
|
cell parts are bigger , molecules are much smaller.
