What is a Plant?

3
Multicellular, eukaryotic, autotroph that uses
chlororplast
4
Most of the photosynthetic activity in plants
takes place in _____ of a leaf.
5
 
Mesophyll
6
Oxygen carbon diffuse in and out of pores
called _____
7
Stomata (stomates)
8
Explain the difference betweena gametophyte a
sporophyte
9
Gametophyte haploid half a set of
chromosomesSporophyte- diploid full set
10
Without gas exchange plants could not
11
Make food
12
What does a plant need to survive?
13
Sunlight, water nutrients, gas exchange
14
Explain the force that allows water to move up a
plant.What is it called when water leaves the
leaf?
15
Cohesion AdhesionTranspiration
16
The 2 types of vascular tissue in a plant are
__________ which moves____________
______________ which moves ______________.
17
Xylem WaterPhloem Sugar (glucose)
18
Plants evolved many things to deal with water
shortage including
19
Cuticle, smaller leaves, (close stomata during
the day)C4, increase of ABA
20
Explain phototropism. What hormone allows for
this?
21
Plants growth towards like. Auxin (not evenly
distributed)
22
What is true about seeds?
23
Not found in all plants, they are found in
gymnosperms and angiosperms, have nutrients for
embryo
24
Where is new plant growth occurring? What process
is happening exactly?
25
Meristems mitosis
26
Identify Structure B. in a LeafFunction?
27
Stomata gas exchange
28
Identify Structure CWhats the function?
C
29
Spongy mesophyll space for gases needed for
photosynthesis
30
Identify the Structures D.Whats there function?
Tissue Type?
31
Vascular tissue movement of water sugar
32
Explain the difference between gymnosperms and
angiosperms
33
Gymno-naked seeds, cones, single
fertilizationAngio- covered seeds,
fruits/flowers, double fertilization
34
What is created by dermal tissue? What are the
benefits of these tissues?
35
Root hairs and trichomes on a leaf, increase
surface area for water absorption and
photosynthesis
36
If one very ripe fruit is in your basket what
hormone is bring released? What hormone is
turned off to allow for a plant to start doing
secondary growth (grow more bushy)?
37
Ethylene Auxin
38
After fertilization ovary becomes the _________
and the ovule becomes the __________
39
Ovary- fruitOvule - seed
40
What kind of animal would be the best to have the
widest seed dispersal?Seeds for animals are
usually kept in ______.
41
Bird or Batsince they fly long distances.
Fleshy sweet fruits
42
What is germination? What does a seed wait for to
start germinating?What hormone is washed away
for this to begin?
43
When a seed starts to grow, water/fire/temperature
, Abscisic Acid (ABA)
44
The female reproductive parts are all
called_______. Consist of.
45
Pistil stigma, style, ovary, ovules
46
Identify structure C. What does it produce? What
is inside these cells?
47
Anther make pollen 3 cells 2 sperm and one cell
to make the pollen tube.
48
Identify Structure A. Function?
49
Stigma Gets pollen
50
Explain what is happening here.
51
The pollen grain or microsporocyte lands on the
stigma and grows a pollen tube that heads towards
the microphyle. The pollen releases 2 sperm cells
into the megasporagium one fertilizes the polar
nuclei forming endosperm the other fertilizes the
egg and becomes the seed
