(thicker at the corners)
Which vascular tissue transports water up the plant?
Xylem
(trahceids and vessel elements)
Which type of ground tisse are these cells and example of?
parenchyma
Which type of root is this?
taproot
Which ground tissue cell allows a plant to be flexible?
collenchyma
What in the stamen holds up the anther?;
filament
What are the two main types of dermal tissue?
Epidermis
Hairs
What is the following showing?
Anther
Which ground tissue cell give the plant it’s strenght?
sclerenchyma
Which phloem cells transports the substance around the plant?
Sieve tube members
(controlled by companion cells)
Which type of angiosperm is this an exaple of?
Monocot
(flower parts in multiples of 3)
Which female gametophyte stucture is the site of pollination?
stigma
After double fertilization what becomes of the ovule
Turns into a seed
Which organs are found within the shoot system?
leaves and stem
Collectively what are all four parts called?
pistil or carpel
After double fertilization what becomes of the ovary
becomes a fruit
Which tissue fills the interior of roots, stems and leaves?
Ground tissue
What do sclerenchyma cells have in their cell walls
cellulose and lignin
Which vacular tissue transports a product of photosynthesis?
Phloem (moves glucose down the plant)
During angiosperm reproduction, the ovule is double feritized. What is formed during each of those fertilizations?
1st: zygote–>embryo
2nd: endosperm (food)
Which type of tropism are the shoots of this plant exhibitting?
positive phototropism
(growth toward light stimulus)
Which type of root is this an example of?
fibrous
Which tissue transports substances thoughout the plant?
Vascular tissue
Which type of ground tissue cells are these?
sclerenchyma
(uniformly thick cell walls)
What dermal tissue structures are seen in this picture?
trichomes
(hairs on stems and leaves)
What is the alternate name for the stem?
shoot
Which type of tropism is this tendril exhibitting?
positive thigmotropism
(growth towards touch)
Which plant organ photosynthesizes?
leaf
What are the pores within the epidermas called?
Stomata
Identify letters A-E
- A: anther
- B: filament
- C: stigma
- D: Style
- E: ovary
What opens the stomata during gas exchange to allow for photosynthesis?
Guard cells when they are turgid (high osmotic pressure)
