Which of the following statements about algae and plants is true?

The evolution of cuticle presented plants with a challenge that threatened their ability to live on land. Describe this challenge, and explain why stomata represent a solution. Compare and contrast stomata with the pores found in liverworts.

Predict how the following conditions would affect the production of O2, ATP, and NADPH and state whether noncyclic or cyclic electron flow would occur in each;(3) blue and red photons hit a chloroplast, but a proton channel has been introduced into the thylakoid membrane, so it is fully permeable to protons.

An investigator exposes chloroplasts to 700-nm photons and observes low O2 production, but high ATP production. Which of the following best explains this observation?a. The electrons from water are directly transferred to NADP+, which is used to generate ATP.b. Photosystem II is not splitting water, and the ATP is being produced by cycling electrons via photosystem I.c. The O2 is being converted to water as a terminal electron acceptor in the production of ATP.d. Electron transport has stopped and ATP is being produced by the Calvin cycle.

The development of the __________ prevents plants from drying out and protects them from microbes.

Which of the following homologies is/are shared by land plants and their closest living algal relatives?
