middle portion Develop into transition zone b/w root and stem

Question 30

Epicotyl

Answer 30

part attached to cotyledons Develop into above ground structures of plant (stem, leaves, flowers)

Answer 31

after pollination

Question 32

Answer 32

ovary (bottom of flower)

Question 33

fruit function

Answer 33

seed dispersal + allow plant to reproduce

Question 34

2 ways fruit gets dispersed

Answer 34

1. juicy and fresh fruit (dispersed by animals feces) 2. dry fruit (dispersed by different media) ex: Dandelion seeds dispersed by wind

Question 35

3 fruit dispersal mechanism

water, wind, animal

Question 36

can plants reproduce without seed

Answer 36

yes

Question 37

why plants being asexual type is not favorable

Answer 37

Doesn’t produce much Requires external force + time Does not provide genetic variation Offspring identical to parent plant
