Plant Parts
Dead cells that transport water and minerals.
What organelle is required for photosynthesis?
Chloroplasts
Plants need water in their cells to maintain pressure and avoid wilting. This pressure is known as...
Turgor pressure.
What is a tropism?
A pattern of growth in response to a stimulus.
Vascular tissue that transports sugars.
Phloem
Do plants undergo cellular respiration?
Yes
Name the phenomenon responsible for moving water up the plant.
Transpiration pull.
What hormone is responsible for the tropisms we discussed?
Auxin
Name the three layers of plant tissue and give one example of each.
Dermal (eg. root hairs), Ground (eg. palisade cells), Vascular (eg. xylem)
What are the inputs of photosynthesis?
Carbon dioxide, water, solar energy
Name the two sources of pressure that cause water to move up the plant.
Root pressure, transpiration pressure
Name and define the three tropisms we discussed.
Phototropism, Gravitropism, Thigmotropism
These absorb potassium ions when exposed to sunlight.
Guard cells.
What are the outputs of cellular respiration?
Carbon dioxide, water, ATP
This makes the roots hypertonic to the soil, so water follows the solute.
Name the three sets of historically significant scientists regarding tropisms.
Darwin, Boysen-Jensen, Cholodny-Went
Name the two types of mesophyll and their function.
Palisade cells under the epidermal layer to photosynthesize. Spongy mesophyll cells below that to help gas exchange. Both found in the leaf.
Write the balanced equation for photosynthesis, including everything.
6 CO2 + 6 H2O + Solar Energy -> C6H12O6 + 6O2
Describe the process of water moving up the plant, from roots to leaves, using key terms.
I want to hear root pressure, transpiration pull, and transpiration.
Explain how auxin would cause a plant to bend away from gravity.
Gravity pulls auxin down, causing the cells on the lower half of the stem to grow longer, and causing the shoot to bend upwards.
