Question 10. Plants often modify their body to adapt to their environments. In especially dry areas, some plants lose their leaves and flatten their stems to reduce water loss. If stems and leaves look similar, how do you tell them apart; i.e. what is a diagnostic feature of stems?
- Why would the same species of tree grow tall with few branches in some environments, versus remaining short and heavily branched in others?
- Why do trees drop certain leaves, in terms of photosynthesis and respiration?
- Why do some grasses have many thin upward facing leave, while others have horizontally oriented leaves?
- Why does guttation happen at night? Relate to water potential and transpiration.
- Know some mechanisms that plants use to deal with dry environments.
- Broadly know difference between bulk flow and short distance transport.
- How the root hairs, cortex, and endodermis function in bringing the necessary minerals and water to the plant while not letting in unneeded minerals?
What transport route is cut-off by the endodermis?
