lesson 3- cell as an efficient open system

Question 1

what may organisms be comprised of?

Answer 1

unicellular or multicellular cells

Question 2

organelles

Answer 2

specialized structures within a cell carrying out specific functions

Question 3

cell membrane

Answer 3

selectively permeable separating the inside of a cell from its exterior environment

Question 4

cytoplasm

Answer 4

thick liquid (aqueous solution) filling the cell and holding the organelles together

Question 5

what holds the organelles together and inplace?

Answer 5

cytoplasm

Question 6

nucleus

Answer 6

membrane bound organelle containing genetic material (DNA)

Question 7

DNA comes from where?

Answer 7

the nucleus

Question 8

mitochondrion (aka mitochondria)

Answer 8

cellular respiration takes place in the organelle, (providing energy for the cell) (power house of the cell)

Question 9

ribosome

Answer 9

genetic instructions are turned into amino acids, and makes PORTEINSS

Question 10

lysosome

Answer 10

enzyme filled organelles serve break down waste materials inside cell

Question 11

rough ER (Endoplasmic Reticulum)

Answer 11

tube like organelle covered in ribosomes, synthesizes and transports proteins

Question 12

golgi apparatus

Answer 12

processes and packages macromolecules for secretion outside cell

Question 13

smooth ER (Endoplasmic Reticulum)

Answer 13

synthesizes and transports lipids and steroids

Question 14

centrioles

Answer 14

cell division spatial arrangement of the cell

Question 15

plant cell differentiation from animal cell (3 differences)

Answer 15

1. cell wall
2. chloroplasts
3. vacuole

Question 16

cell wall

Answer 16

provides rigidity and strength to cell and protects against mechanical stresses

Question 17

chloroplast

Answer 17

photosynthesis takes place. certain protists (algae) possess chloroplasts

Question 18

vacuole

Answer 18

enclosed compartments used for storage
