Question 0

The structure found within the dense area it produces the RNA and proteins that are used to make ribosomes it is found in this location because the process involves using DNA which is stored inside of the nucleus

Answer 0

Nucleolus

Question 1

Stores hereditary information in the DNA molecule

Answer 1

Nucleus

Question 2

Transfers energy from organic compounds to ATP they also have an inner and outer membrane the inner folds or Chris stay contain enzymes needed for chemical reactions they can divide to reproduce because they have their own DNA

Answer 2

Mitochondria

Question 3

Are responsible for building protein these organelles do not have a membrane they can be freely floating in the Lytosol or attached to the rough ER

Answer 3

Ribosomes

Question 4

A network of tubes that transports molecules through the cell. It produces phospholipids and proteins for export from the cell

Answer 4

Rough endoplasmic reticulum

Question 5

A network of tubes that does not contain ribosomes it has different functions in different cell types it produce steroids such as estrogen and testosterone

Answer 5

Smooth endoplasmic reticulum

Question 6

A system of flattened sacks that receives spherical best vesicles from the rough ER it produces vesicles containing lipids or proteins that have been modified for export with an address label it then packages them into new vesicles to travel to other cell parts

Answer 6

Golgi apparatus

Question 7

A small spherical shape sack surrounded by a single membrane they contain carbohydrates lipid or protein monomers and polymers they transport these things within and between cells by fusing with the cell membrane

Answer 7

Vesicles

Question 8

Vesicles produced by the golgi apparatus that contain digestive enzymes they break down large polymers and old cell parts. In the liver they convert glycogen to glucose white blood cells can break down bacteria that invade the cell

Answer 8

Lysosomes

Question 9

Vesicles produced by the rough ER that contain other type of enzymes they detoxify alcohol and other drugs in the liver and kill bacteria. They break down fatty acids to be used for energy. They also neutralize free radicals or oxygen ions that damage cells. They produce hydrogen peroxide to walk hearing out these reactions

Answer 9

Peroxisomes

Question 10

Part of the cytoskeleton composed of hollow protein they form fibers for cell division hold organelles in place and helps the cell to keep its shape

Answer 10

Microtubules

Question 11

Part of the cytoskeleton composed of long threads. they contribute to cell division and cause muscle cells to contract

Answer 11

Microfilaments

Question 12

Many tiny hairlike structures on the outside of cells that aid in movement or trapping particles into the cell they are made of microtubules

Answer 12

Cilia

Question 13

One or a few long tails on the outside of the cell that are used for motion they are made of microtubules

Answer 13

Flagella

Question 14

Short cylinders composed of microtubules that assemble before cell division they form this spidle threads that guides chromosomes

Answer 14

Centrioles

Question 15

A structure surrounding the membrane that is made up of cellulose it is used for structure and support. plants that live many years produce secondary cell walls made of wood

Answer 15

Cell wall

Question 16

A fluid filled sac that occupies a large portion of a plant cell. A large central vacuole stores water enzymes and metabolic waste. smaller vacuoles can store toxins or pigments.

Answer 16

Vacuole

Question 17

Storage structures surrounded by a double membrane that contains DNA like mitochondria. There are four main types chloroplasts contain pigments to absorb light energy and produce sugar, Chromoplasts also contain pigments that give flowers and fruits their color. Amyloplasts are designed to store starch.

Answer 17

Plastid
