Chapter 7 Cells

Question 0

Who discovered bacteria???

Answer 0

Anton van Leeuwenhoek

Question 1

Who discovered cells???

Answer 1

Robert Hooke

Question 2

Are cells like empty chambers????

Answer 2

No they are not, they contain a huge array of working parts each with its own function

Question 3

What is the cell theory????

Answer 3

1. Cells are basic unit of life
 ( Anton van Leeuwenhoek )
2. All plants are made up of cells
 ( Matthias shleiden) 
3. All animals are made up cells
( Theodore Schwann) 
4. New cells can be only produced only from the division of existing cells. 
( Rudolf Virchow)

Question 4

How does a light microscope work???????

Answer 4

A light microscopes allows light to pass throught the specimen and uses two lenses to form image

Question 5

What is electronic microscope

Answer 5

Uses beams of electrons are focuses by magnetic fields offers higher resolutions

Question 6

What are 2 types of electronic microscope

Answer 6

Transmission and scanning
Transmission electron microscope make it possible to explore cells structure and large protein molecules only 2d dimension
Scanning scans over the specimen suface and make 3d form pics

Question 7

What is prokaryote cell

Answer 7

They do not separate there genetic material within nucleus , it’s bacteria!!!!!!!!!

Question 8

What is eukaryotes

Answer 8

nucleus separates DNA from rest of cell ex: human animals plants

Question 9

Defenition of cytoplasm

Answer 9

Material inside the membrane not including the nucleus

Question 10

Defenetion of organells

Answer 10

Little organs of the cell

Question 11

Defenetion of nucleus

Answer 11

The nucleus contains nearly all the cells DNA and with it the code it instructions for making proteins and other important molecule

Question 12

Definition of vacuole

Answer 12

Vacuoles store materials like water salt proteins and carbohydrates

Question 13

What are lysosomes

Answer 13

Lysosomes breakdown lipids carbohydrates and proteins into small molecules that can be used by the rest of the cell so they are also involved in breaking down organelles that they have outlived their usefulness

Question 14

Definition of cytoskeleton

Answer 14

Eukaryotic cells are given their shape and internal organization by a network of protein filaments known as the cytoskeleton

Cytoskeleton helps the cell maintain its shape and also involved in movement

Question 15

What is microfilaments

Answer 15

Microfilaments support this so it also help to cell move

Question 16

What is microtubules

Answer 16

They helped the cell so keep it shape

Question 17

What are centrioles

Answer 17

It helps organize cell division

Question 18

What are ribosomes

Answer 18

Proteins are assembled on ribosomes

Question 19

What is endoplsdmic reticulum

Answer 19

The endoplasmic reticulum is where lipid components of the cell membrane are assembled along with proteins and other materials that are exported from the cell basically it’s like a highway for the cell

Question 20

What is the Goldy apparatus

Answer 20

Is the shipping and packaging of proteins in like a factory

Question 21

What is a chloroplast

Answer 21

Chloroplast capture the energy from sunlight and converts it into food and that contains chemical energy in a process called photosynthesis

Question 22

What is mitochondria

Answer 22

Mitochondria convert the chemical energy stored in food into compounds that are more convenient for the cell of these is basically the powerhouse of the cell

Question 23

What does the cell wall do

Answer 23

It supports, shape, and protects cell

Question 24

What is the cell membrane

Answer 24

All cells contain cell membrane which almost always are made up of double layered sheet called a lipid bilayer the cell membrane regulates what enters and leaves the cell and also protects and supports the cell

Question 25

What is hydrophobic

Answer 25

Is the water hating part of the molecule

Question 26

What is hydrophilic

Answer 26

Is the water loving part of the Molecule

Question 27

What is passive transport

Answer 27

It's with something moves from a lower concentration to a higher concentration without no energy

Question 28

What is diffusion

Answer 28

Diffusion is the driving force behind the movement of my substance across the cell membrane

Question 29

What is facilitated diffusion

Answer 29

In which molecules that cannot directly diffuse across the membrane pass through a special protein channels

Question 30

What is aquaporins

Answer 30

Water channels

Question 31

What is osmosis

Answer 31

Is the diffusion of water through a permarrable membrane

Question 32

What is isotonic

Answer 32

Is the same amount of solute

Question 33

What is hypertonic

Answer 33

It's when it has high concentration inside the cell in the lower concentration outside the cell

Question 34

What is hypotonic

Answer 34

It's when there is Lower concentration inside of the cell in there is a higher concentration outside of the cell

Question 35

What is osmotic pressure

Answer 35

Driven by difference in solution concentration the net movement of water out of or into a cell produces of course known as osmotic pressure

Question 36

What is active transport

Answer 36

The movement of materials against a concentration difference is known as active transport using ATP for energy

Question 37

What is Endocytosis

Answer 37

When the cell eat something

Question 38

What is exocytosis

Answer 38

It's when cell releases waste

Question 39

What is phagocytosis

Answer 39

It's when did eat something solid

Question 40

What is Pinocytosis

Answer 40

It's when the cell so eat something liquid

Question 41

What is homeostasis

Answer 41

How it respond to the environment transform energy and reproduce
