15
Q

This protects the DNA in the nucleus

A

Envelope (membrane)

16
Q

This keeps everything in the nucleus in place

A

Nucleoplasm

17
Q

This is a dense region where ribosomes are made

18
Q

These are found in the cytoplasm and will make proteins for the cell.

A

Free ribosomes

19
Q

These are found attached to the ER and will make proteins that will eventually be shipped.

A

Bound ribosomes

20
Q

This is a system of tubes filled with enzymes that will synthesize hormones, detox materials, and break down lipids.

21
Q

This is a system of sacs covered in ribosomes that will modify proteins

22
Q

This is a stack of hollow, flattened sacs (or pancakes).

A

Golgi apparatus

23
Q

This step by the Golgi is when the protein is received and double checked.

A

Processing

24
This is when the Golgi wraps the protein in membrane and adds a carbohydrate "address" label.
Packaging
25
This is when the Golgi transports the protein to the cell membrane
Shipping
26
Any material wrapped in membrane to move from one place to another is called a
Vesicle
27
These are membrane enclosed catabolic enzymes that, along with a pH of 5, will digest and destroy broken down organelles and foreign material.
Lysosomes
28
These are membrane enclosed enzymes that will neutralize substance such as alcohol and poison into hydrogen peroxide, and then in water.
Peroxisomes
29
This structure of the cytoskeleton is mostly responsible for movement.
Microtubules
30
Two proteins twisted together are responsible for maintenance of shape and placement of organelles.
Microfilaments
31
These cables of twisted protein anchor down organelles and help keep shape.
Intermediate filaments.
32
These are tubes are hair-like and tail-like structures for cells.
Cilia and flagella
33
This is a tough layer of cellulose that provides plant cells with an extra layer of protection.
Cell wall
34
These are openings in the cell wall that allow water and nutrients to pass through.
Plasmodesmata
35
This is an expandable storage sac that will hold everything from water, food, enzymes to waste and organic compounds.
Vacuole
36
These are membranous sacs filled with pigments that will conduct photosynthesis.
Chloroplasts
37
These are membranous sacs filled with pigments that will give color to flowers and fruit.
Chromoplasts
38
This is a gel-like substance composed of water, enzymes, and organic compounds that will help the cell maintain shape and provides shock absorption.
Cytoplasm
