Gibberellins are hormones that are made in roots and grow shoots. How are gibberellins able to move to the shoots?

Gibberellins are transported through vascular tissues (xylem/phloem)

What is the function of flower part labeled D?

Attract pollinators, Produce male sex cells

Which best describes the action of pollen?

Pollen is released from the anther and is transferred to the stigma.

How do plant systems work together to make the movement of liquid possible?

The roots absorb water and move them up the stem, the stem moves food down

Which is an example of gravitropism?

the growth of roots into the soil

The xylem tissue in leaves transports --

the water and minerals that are absorbed by the roots.

Questions 11

Answers

1
What do phototropism and gravitropism (geotropism) enable plants to do?
Grow toward needed resources
Prevent invasion by insect colonies
Defend themselves against herbivores
Develop pesticide resistance by exchanging DNA
2
Gibberellins are hormones that are made in roots and grow shoots. How are gibberellins able to move to the shoots?
Gibberellins are transported through vascular tissues (xylem/phloem)
Gibberellins infect healthy cells and later released to infect other cells.
Gibberellins are absorbed through the stomata and attach to chloroplasts.
Gibberellins become concentrated within plant tissues during mitosis.
3
This growth response results from the __.
conversion of light energy into heat energy
action of contractile fibers
action of plant hormones
conversion of mechanical energy into radiant energy
4
What is the function of flower part labeled D?
Produce female sex cells
Protect petals
Attract pollinators
Produce male sex cells
5
Which best describes the action of pollen?
Pollen moves from the ovule up the style and is released from the stigma
Pollen grows down from the anther through the filament and fuses the egg
Pollen is released from the stigma and is transferred to the anther.
Pollen is released from the anther and is transferred to the stigma.
6
What is the function of flower part labeled B?
Attract pollinators
Protect petals
Produce male sex cells
Produce female sex cells
7
How do plant systems work together to make the movement of liquid possible?
The roots absorb their own water, while the stem gets water through leaves
The roots lose water vapor in soil; stem loses water vapor in the leaves
The roots anchor the plant in the soil, and then stem holds the leaves up.
The roots absorb water and move them up the stem, the stem moves food down
8
Which is an example of gravitropism?
the dropping of fruit
the turning of leaves towards the sun
the growth of roots into the soil
the horizontal growth of roots towards water
9
What is the function of flower part labeled A?
Produce female sex cells
Attract pollinators
Produce male sex cells
Protect petals
10
The xylem tissue in leaves transports --
the oxygen that regulates the rate of carbohydrate production
the bacteria needed for nitrogen fixation in root nodules.
the water and minerals that are absorbed by the roots.
the wax required to coat the surface of actively growing tissue.
11
In this situation, which plant system is working with the response system?
Root System
Immune System
Vascular System
Reproductive System
