chapter 4 cells Flashcards
name two substances that are transported around a plant in the xylem
water and ions
what is the function of air spaces?
increase rate of diffusion of gases
how is palisade mesophyll tissue adapted for the function of photosynthesis
it contains lots of chloroplasts, where photosynthesis takes place, and is located near the top of the leaf so that the chloroplasts can get the most light
what is a xylem tissue?
transports water and mineral ions from the roots to the stems and leaves
what is phloem tissues?
transports dissolved sugars from the leaves to the rest of the plant.
what is translocation?
the movement of dissolved sugars from the leaves to the rest of the plant
the process by which water is lost from a plant is called_______
transpiration
transpiration is caused by the ________ and diffusion of water from a plant’s surface
evaporation
translocation is the transport of _____ from where they’re made in the leaves to the rest of the plant via the ________
sugars
phloem
why is water lost through the stomata?
the stomata open to let in carbon dioxide for photosynthesis
what does the stomata and the guard cells controls?
controls gas exchanges and water loss
when is transpiration more rapid?
hot, dry, windy or bright conditions
factors that increase the rate of photosynthesis or increase the stomata opening will increase the ______________
rate if transpiration
