chapter 7 section 1,2

Question 0

prokaryotes

Answer 0

cells that don’t have a nucleus thus their generic blue print DNA is spilled across the cytoplasm.

Question 1

eukaryotes

Answer 1

are cells that enclose their DNA in a nucleus

Question 2

phospholipid bilayer

Answer 2

cell membranes

Question 3

mycoplasma bacteria

Answer 3

the smallest cell

Question 4

amebas

Answer 4

largest cell

Question 5

light microscope

Answer 5

allows light to pass through the specimen and uses two lenses to form an image.

Question 6

objectives

Answer 6

a rotational device that holds the lenses of a microscope.

Question 7

electron microscope

Answer 7

allows for greater magnification and resolution due to its abilitty to use electrons that are focused by magneticdec fields.

Question 8

two types of electron microscopes

Answer 8

1) transmission electron microscope

2) Scanning electro microscope.

Question 9

cell organization

Answer 9

basic division of the cell into two main structures. (Cytoplasm and nucleus)

Question 10

cytoplasm

Answer 10

the portion of the cell outside the nucleus where all the organells and proteins are suspended in a water medium.

Question 11

organells

Answer 11

specialized structures inside a cell with precise structures and function.

Question 12

typres of organells

Answer 12

1. Golgi body
2. Endoplasmic reticulum
3. mitochondria
4. lysosomes
5. vavoules
6. ribosomes
7. centrioles

Question 13

nucleus

Answer 13

double membrane bound organelle where the cells genetic blueprint or DNA is stored.

Question 14

Nuclear envelope

Answer 14

a double membrane containing special pores where genetic information in the form of RNA leave the nucleus.

Question 15

chromatin

Answer 15

a structure inside the nucleus where the DNA is mixd with the proteins.

Question 16

Nucleolus

Answer 16

a region at the center of the nucleus where ribosomes are produced.

Question 17

vacuoles

Answer 17

a sac-like membrane enclosed structure that stores lipids, proteins, water and carbohydrates.

Question 18

Lysosomes

Answer 18

small organelles filled with enzymes with the sole purpose of breaking down macromolecules into smaller compounds to recycle.

Question 19

cytoskeleton

Answer 19

the outside structure of a cell that gives it support.

Question 20

microfilaments

Answer 20

thread like structure made out of a protein called actin which produces a touch network of filaments

Question 21

endoplasmic reticulum

Answer 21

eukaryotic cells contain an internal membrane system that is connected to the nucleus.

Question 22

Proteins made in the rough ER

Answer 22

Include those that will be released, or secreted from the cell, or proteins that will be placed on the membrane of the cell

Question 23

Smooth endoplasmic reticulum

Answer 23

enzymes which brake down protein and packaged it the protein bound vesicles and / or vacuoles called lysosomes in the ER

Question 24

Golgi body

Answer 24

The Golgi apparatus modifies, sorts and packages proteins and other materials created the ER destined for exiting the cell
