They would have different water retention and utilization strategies

Desert plants would have larger spines

Desert plants would have no woody bark due to lack of herbivores

Desert plants would have more seeds than plants in the rainforests

Provide secondary growth in woody plants

Provide nutrients to apical meristems

Maintain water homeostasis

Stimulate root hair growth

Vascular tissue

Dermal tissue

Vascular cambium

Sclerenchyma

Ground tissue

Grow a sample of plants in a potassium-rich environment and another sample in a potassium-deprived environment

Measure the amount of potassium in a sample of plants

Use autoradiography to find potassium in leaf tissues

Measure how fast radioactive potassium enters the plant

Analyze root contents for potassium

From the anther to the stigma

From the stigma to the anther

From the pollen tube to the ovary

From the stamen to the ovary

Ethylene

Cytokinins

Abscisic acid (ABA)

Gibberellins

It produces spores, which grow into gametophytes

It produce seeds, which grow into gametophytes

It produce zygotes, which grow into gametophytes

It produce zygotes, which grow into sporophytes

None of these

Only male gingko plants

Only female gingko plants

Both male and female gingko plants

Niether; diecious plants do not produce pollen

All male gingko plants and some female gingko plants

Transpiration from the tree's leaves causes tension (negative pressure) to increase in the tree's xylem. As water exits the leaves, the cohesion of water molecules pulls more molecules into the roots and upward.

Transpiration from the tree's leaves causes tension (negative pressure) to increase in the tree's phloem. As water exits the leaves, the adhesion of water molecules pulls more molecules into the roots and upward.
