cells and cell function

Question 1

what is the difference between a plant and animal cell?

Answer 1

plants have a cell wall and cell membrane and animal only have a cell membrane

Question 2

how does the structure of the cell membrane relate to diffusion?

Answer 2

molecules move across the membrane, which is diffusion

Question 3

smooth endoplasmic reticulum

Answer 3

eukaryotic; detoxifies the cell and makes lipids

Question 4

what is the cell theory?

Answer 4

all the plants and animals are composed of of cells and cells are the basic unit of life

Question 5

golgi bodies

Answer 5

eukaryotic; sorts and ships proteins

Question 6

vacuoles

Answer 6

eukaryotic; stores water and nutrients

Question 7

vesicles

Answer 7

eukaryotic; transport materials around the cell

Question 8

what is the difference between osmosis and diffusion?

Answer 8

osmosis is the diffusion of water across a membrane, and diffusion is when molecules move across a membrane

Question 9

cell membrane

Answer 9

all; a thin flexible barrier that separates the cell from its enviroment

Question 10

what is the importance of polarity with respect to the membrane?

Answer 10

if a membrane is polar, electrons present on the membrane will not be evenly distributed which causes one side of the molecule to be more charged than the other

Question 11

what roles do vacuoles play in plant cells?

Answer 11

storage and transport, environmental stability, response to injury

Question 12

mitochondria

Answer 12

eukaryotic; makes energy

Question 13

what is the function and structure of the cell wall?

Answer 13

it surrounds the plasma membrane of plant cells and allows cells to develop turgor pressure

Question 14

what is the importance of particle size with respect to the cell membrane?

Answer 14

if a particle is smaller, it will be easier for it do be diffused across the membrane rather than if it were big

Question 15

cell wall

Answer 15

plants, fungi, and prokaryotes; rigid barrier that protects the cell

Question 16

cytoskeleton

Answer 16

eukaryotic; structure, support and transport

Question 17

why are cell membranes made of lipids?

Answer 17

because of their flexibility it is good for the membrane

Question 18

lysosome

Answer 18

eukaryotic, animal cells only; removes unwanted material and waste

Question 19

what are the parts of the cytoskeleton?

Answer 19

microtubules and filaments

Question 20

what is the difference from active, facilitated, and passive transport?

Answer 20

passive does not require energy, active transport does require energy, and facilitated is a type of passive transport

Question 21

nucleolus

Answer 21

eukaryotic; makes ribosomes

Question 22

nucleus

Answer 22

eukaryotic; stores genetic information

Question 23

what roles do vacuoles play in animal cells?

Answer 23

remove waste productsw

Question 24

why are cell membranes important?

Answer 24

because they protect and organize the cell

Question 25

cytoplasm

Answer 25

all cells; contains the contents of cells

Question 26

ribosome

Answer 26

all cells; makes proteins

Question 27

how is digestion connected to cell structure?

Answer 27

lysosomes function as the digestion system of the cell

Question 28

what are the differences between prokaryotes and eukaryotes?

Answer 28

prokaryotes are unicellular and store their DNA in cytoplasm and eukaryotes have multiple cells and store their DNA in the nucleus

Question 29

chloroplasts

Answer 29

plants only; makes food using the process of photosynthesis

Question 30

how does the membrane respond to changes in concentration?

Answer 30

the membrane becomes more permeable

Question 31

rough endoplasmic reticulum

Answer 31

eukaryotic, makes proteins fro the endomembrane system

Question 32

how do the organelles work together?

Answer 32

by communicating with each other through vesicle passageways
