Answer 3

Portion of cell outside of nucleus

Question 4

What organelles contains almost all of the cell’s DNA

Answer 4

The nucleus

Question 5

What is the nucleus surrounded by

Answer 5

A nuclear membrane dotted with pores

Question 6

What is the nucleoplasm

Answer 6

The semi-liquid portion inside the nucleus

Question 7

Function of the nucleolus

Answer 7

To manufacture the subunits that make up ribosomes

Question 8

Point of the subunits (large subunit & small subunit) of the nucleolus

Answer 8

The subunits pass through the pores of the nucleus to the cytoplasm where they combine to form ribosomes

Question 9

Functions of the nucleus

Answer 9

The carrier of genetic information
Controls reproduction of the cell
Directs protein synthesis

Question 10

How does the nucleus direct protein synthesis

Answer 10

By sending messages to the ribosomes

Question 11

Where can the ribosomes be found

Answer 11

Free floating in the cytoplasm or attached to the ER

Question 12

Where is the site of protein synthesis

Answer 12

Ribosomes

Question 13

All protein cells are made of what

Answer 13

Ribosomes

Question 14

What is the endoplasmic reticulum

Answer 14

The internal membrane system

Question 15

What does the ER connect

Answer 15

The nuclear membrane to the cell membrane

Question 16

Smooth ER information

Answer 16

Has no ribosomes

Function is to make lipids used in cell membrane

Question 17

Rough ER information

Answer 17

Has ribosomes attached

Makes proteins

Question 18

Function of ribosomes on ER

Answer 18

Newly made proteins leave the ribosome and are inserted into spaces of ER

Question 19

Proteins made in the rough ER go where

Answer 19

Golgi apparatus

Question 20

Function of Golgi apparatus

Answer 20

To modify, sort, & and package proteins

Question 21

What are the physical aspects of Lysosomes

Answer 21

Sacks in the cell filled with very strong digestive enzymes

Question 22

What can Lysosomes digest

Answer 22

Carbs, proteins, and lipids into small molecules

Question 23

Lysosomes destroy what

Answer 23

Old organelles

Question 24

Why are the lysosomes surrounded by thick membrane

Answer 24

Because the cell would be destroyed if enzymes were released

Question 25

What is the point of the vacuoles

Answer 25

The storage area inside the cell - to store water, salts, proteins, and carbs

Question 26

What is the powerhouse of the cell

Answer 26

The mitochondria

Question 27

What is the purpose of the mitochondria

Answer 27

Cellular respiration

Question 28

What is cellular respiration

Answer 28

Process of converting glucose molecules into a usable form of energy for the cell

Question 29

The mitochondria has an inner membrane & outer membrane - what are the folds called

Answer 29

Cristae and help increase the surface area for respiration

Question 30

What is the cytoskeleton

Answer 30

An internal framework and support system with a network of protein tubes and fibers

Question 31

About the microfilaments in the cytoskeleton

Answer 31

Solid, thread like, protein structures that help cells to move

Question 32

About the microtubules int he cytoskeleton

Answer 32

Tubes that help cell shape, separation of chromosomes during cell division, and with the formation of the cilia and flagella

Question 33

Another name for the cell membrane

Answer 33

The plasma membrane

Question 34

Functions of the cell mmbrane

Answer 34

To maintain the shape of the cell, separate one cell from the next, and regulate what goes in and out of the cell
