“mouth” of the cell, controls what comes in and out of the cell

Question 8

What would happen if you blocked the stomata?

Answer 8

Photosynthesis would decrease because there wouldn’t be enough CO2 in the cell

Facilitated Diffusion

Answer 9

requires transport proteins but still moves down gradient and doesn’t need energy

Question 10

Gastrula

Answer 10

cells migrate inward to form a fold

Question 11

Collagen

Answer 11

molecules are bundled like steel wires in a cable, in muscles, the fibers that create muscles (unique to animals)

Question 12

Co-evolution

Answer 12

species influence each other (insects and flowers)

Question 13

Pollination

Answer 13

the transfer of pollen from male to female plant (transfer across 2 genetically different plants)

Question 14

Carpel

Answer 14

the extra layer surrounding angiosperms

Question 15

Gymnosperms

Answer 15

naked seeds, developing seed

Question 16

Endocytosis

Answer 16

the taking in of matter by a living cell by invagination of its membrane to form a vacuole

Question 17

Exocytosis

Answer 17

a process by which the contents of a cell vacuole are released to the exterior through fusion of the vacuole membrane with the cell membrane

Question 18

Seed

Answer 18

a baby plant in a box with its lunch

Question 19

Xylem

Answer 19

moves water and dissolved minerals in and out of the cell

Question 20

Phloem

Answer 20

moves food in and out of the cell

Question 21

Stomata

Answer 21

controls water loss, the “mouth” of plants, controls what comes in and out of the cell

Question 22

Angiosperm

Answer 22

have an extra layer (carpel) surrounding the seeds- are able to reproduce easily and have a protective coating around the seeds

Question 23

Notochord

Answer 23

a skeletal rod supporting the body that is only in embryos for vertebrates (all vertebrates have a notochord at some point)

Question 24

Radula

Answer 24

scraping tongue in mollusks

Question 25

Tissue

Answer 25

cellular pipes for transport of water/minerals

Question 26

Gametophyte

Answer 26

in the life cycle of plants with alternating generations, the gamete-producing and usually haploid phase, producing the zygote in which the sporophyte arises

Question 27

Spores

Answer 27

a unit of sexual or asexual reproduction that may be adapted for dispersal and for survival

Question 28

Sporophyte

Answer 28

the asexual and usually diploid phase, producing spores from which the gametophyte arises

Question 29

Bilateria

Answer 29

can cut in half, bilateral symmetry helps you to move better, you can also have better directional sense

Question 30

Cnidaria

Answer 30

corals and jellyfish- has one opening and digestive cavity inside, triggered by tough, radial symmetry

Question 31

Protostomes

Answer 31

"first mouth" gastrula becomes mouth first

Question 32

Arthropods

Answer 32

insects, crustaceans, support, movement, protection, have exoskeleton, critical for transition to land (water retention) growth requires molting, appendeges that function as weapons, joined feet

Question 33

Mollusks

Answer 33

snails, clams, squid (radula-scraping tongue)

Question 34

Duterme

Answer 34

"second mouth" becomes anus first, vertabrates (US) and other

Question 35

Bilatairans

Answer 35

have at least 2 holes

Question 36

Porifera

Answer 36

sponges, don't have tissues, muscles, nerves, and are not mobile (only have collagen in common with other animals)

Question 37

Filter feeding

Answer 37

flagellated cells draw water into the cavity and ingest food (mostly marine)

Question 38

Vascular plants

Answer 38

seed plants

Question 39

Lycophytes

Answer 39

non seed plants

Question 40

Ferns

Answer 40

often begin as fiddleheads, unroll and expand, often clusters of spore-inducing structures on underside- reproduce from spores- very diverse

Question 41

Gymnosperms

Answer 41

male and female cones

Question 42

Embryo

Answer 42

baby sporophyte and nutrient protected by a seed coat

Question 43

What is sister to land plants?

Answer 43

green algae

Question 44

Xylem

Answer 44

moves water and dissolved minerals

Question 45

Phloem

Answer 45

moves phood

Question 46

How do your cells control the movement of water

Answer 46

cells actively transport solutes across the membrane to control the movement of water

Question 47

Active transport

Answer 47

it has to be moving from low concentration to high concentration, uses energy

Question 48

Facilitated Diffusion

Answer 48

if too large and too hydrophillic, they will slide through protein channels

Question 49

Simple Diffusion

Answer 49

slide straight on through if small and hydrophobic

Question 50

Negative Feedback Loop

Answer 50

high blood glucose (stimulus) notifies the pancreas (sensor) which triggers insulin the the effector is that the body takes up glucose, muscle and liver take up/store glucose which leads to decreased blood glucose levels

Question 51

Positive Feedback Loop

Answer 51

low blood glucose (stimulus) notifies the pancreas (sensor) which triggers glycogen (sends glucose stored in body into bloodstream) the effector is that the muscle and liver release glucose to increase blood glucose

Question 52

Negative Feedback Loop

Answer 52

helps with balance (homeostasis)

Question 53

Positive Feedback Loop

Answer 53

shoots things up or down

Question 54

Answer 54

2n

Question 55

Gametophyte

Answer 55
