Definition
All cells have these four things: Cell membrane, Cytoplasm, Genetic Material/DNA, ________.
Term
Prokaryotic, Eukaryotic
Definition
There are two type of cell types?
Term
Prokaryotic
Definition
A single-celled organism, that has no nucleus, no organelles (except ridosomes) and DNA within the cytoplasm
Term
Eukaryotic
Definition
This is a plant, animals, and fungis cell. It has a nucleus, Has DNA within the nucleus, it posses various cell organelles.
Term
Bi-layer
Definition
Another term for a double layer of phospholipids is _____
Term
Cell Membrane
Definition
A double layer of phospholipids. Has some Carbohydrates, Proteins, and Cholesterol (HDL) is what part of a cell?
Term
Carbohydrates
Definition
These things are on the outside of the cell membrane and they identify what type of cell it is and who it belongs too.
Term
Proteins
Definition
These things stick out of the cell membranes and act like tunnels to transport things.
Term
Cell Wall
Definition
Only plants have this. It is an extra layer over the cell membrane and it is very hard.
Term
Plasmodesmata
Definition
These are on the cell walls. They are openings in the cell wall to pass information between cells.
Term
Nucleus
Definition
This is the control structure of the cell, it has an outside layer of phospholopids.
Term
Nucleus
Definition
This cell structure has Chromatin, a nucleolus, and pores.
Term
Pore
Definition
This hole allows certain materials to pass in and out of the nucleus.
Term
RNA
Definition
DNA inside the nucleus makes ____ to be a messanger to get the job done.
Term
Chromatin
Definition
This is inside the nucleus and is divided into genes and every gene has DNA, it looks like spagetti and can change into a fat rod that is called chromosome.
Term
Nucleolus
Definition
The structure inside the nucleus that makes ribosomes.
Term
Ribosomes
Definition
These are made in the nucleolus and they make proteins and travel out of the nucleus's pores.
Term

Term
Endoplasmic Reticulum (ER)
Definition
It is around the nucleus, has open channels, has two types, puts proteins into containers and ships them somewhere.
Term
Rough ER
Definition
This has ridosomes and is a protein factory
Term
Smooth ER
Definition
This has no Ribosomes and it makes carbs and lipids.
Term
Golgi
Definition
This area has flatten tubes, collects proteins and reforms them and sends them somewhere.
Term
"cis"
Definition
The area in the Golgi where proteins are recieved.
Term
"trans"
Definition
THe area in the golgi where proteins and things are sent out.
Term
Lysosomes
Definition
A bag of enzeymes that can digest food and can digest damaged organelle parts.
Term
Autophagy
Definition
The process of "self-eating" is called ____
Term
Peroxisomes
Definition
This has enzeymes that breakdown peroxide (H 2 O 2). Animals have this, plants don't always have this.
Term
Catalase
Definition
The enzyme that is inside Peroxisomes is called ____.
Term
Plastids
Definition
Bags that are inside plants that give them colors.
Term
Chloroplasts
Definition
These plastids have chlorophyll (green) pigment filled, these are photosythesis plants.
Term
Leucoplasts
Definition
These plastidsare Anylose (starch) filled (White).
Term
Chromoplasts
Definition
These plastids have carotene (orange) pigment filled.
Term
Chloroplasts
Definition
This is a green bag that is clear, It is a outer layer of phosphlipids, insides are discs.
Term
Thylakoid

This organelle is in plants and animals and we feed this everyday and it makes energy for us.
Term
ATP (energy)
Definition
The mitochondria takes sugar and oxygen and converts it into water and carbon dioxide and creates ____
Term
