Science test

Question 1

Unicellular vs multicellular

Answer 1

Unicellular: Tend to have shorter lives, do not have cell differentiation, offspring are identical, reproduce faster, and are less complex

Multicellular: Consist of many cells, organisms can grow larger, more complex, have cell differentiation, ability to adapt

Question 2

Cell organelles

Answer 2

cell wall, cell membrane, vacoule, lysosomes, chlorplasts, golgi, rough and smooth ER, cytoplasm, ribosomes, mitochondira, nucleus

Question 3

3 types of bacteria

Answer 3

rod, spiral, spherical

Question 4

difference between bacteria and archaea

Answer 4

Bacteria: can only live in normal conditions
archaea: have the abilty to live in extreme conditions such as volcanoes, geysers, etc.

Question 5

significance of bacteria lab

Answer 5

the main purpose is to learn how bacteria can reproduce. if you don’t take your antibiotics on time, then they can reproduce faster, some are extremely resistant and eventually get killed once the other vulnerable ones get killed

Question 6

antibiotics

Answer 6

medicines which kill bacteria, not viruses

Question 7

antibodies

Answer 7

protiens which protect your body from unwanted stuff

Question 8

prokayortic vs eukayortic

Answer 8

prokayortic: no nucleus, less complex, DNA floats, no membrane bound organelles
eukayortic: has a nucleus, DNA is structured, membrane bound organelles, complex

Question 9

protist

Answer 9

eukayortes that have both plant and animal characteristics

Question 10

true or false: can protists be unicellular or multicellular?

Answer 10

true

Question 11

multicellular protists

Answer 11

e.x. volvox

Question 12

plant-like and animal-like protists

Answer 12

plant-like: diatoms, euglena, volvox
animal-like: amoeba, paramecium

Question 13

how are protists different from prokayortes?

Answer 13

they are eukayortes; which means they have a nucleus and membrane bound organelles

Question 14

how are protists different from other eukayortes?

Answer 14

they are not classified as a plant or animal cell

Question 15

the 4 protists

Answer 15

euglena, volvox, paramecium, amoeba

Question 16

plant-like protists

Answer 16

euglena and volvox since they have chloroplasts and do the process of photosynthesis

Question 17

non-unicellular protists

Answer 17

kelp ,volvox, algar

Question 18

how do these protists move

Answer 18

Euglena: flagella
paramecium- cilla
amoeba- false food called pseudopod
volvox- flagella

Question 19

2 reasons why spirogyra, elodea, onion and skin cells are eukayortes and not protists

Answer 19

1. they have a nucleus and membrane bound organelles, and can be classified
2. all of these are multicellular
