PUULIUI The stomata epidermal cells of monocotyledons plants are straight and in parallel lines True False
2. Why do plants need stomata? alowing to dlose and open, to protect the plante frem loss) 3. What is the function of the leaf epidermal cells in terrestrial plants? 4 What does the parenchyma of a leaf do? Achiye n Photosy nthasis and stems 5. Name a few plant organelles and structures that are not found in animals. List their functions. on Ma 6. What are the differences between monocot and dicot leaves? ren ween the two as you...
In transpiration, water exits the leaves through the (guard cell / stomata ). When guard cells are turgid a plant's stomata open, when guard cells are flaccid a plant's stomata are closed. True False
Prove that in hyperbolic geometry, the following statement is false: Any two parallel hyperbolic straight lines have a common perpendicular hyperbolic straight line.
Suppose lines n and O are parallel. True or false? One can conclude in Euclidean Geometry that <9 is congruent to <7. L m t 1 45 n 23 6 7 8 912 0 14 15 13 10 11
CAM plants keep stomata closed in the daytime, thus reducing loss of water. They can do this because they Ofix CO2 into pyruvate in the mesophyll cells Ofix CO2 into sugars in the bundle sheath cells use photosystem I and photosystem II at night fix CO2 into organic acids during the night
A. CELLS ON THE SURFACE 1. Peel the epidermis from the lower side of a plant leaf and observe epidermal cell shape and quard cells. What to most epidermal cells look like? Why are they shaped that way? Do they contain chloroplasts? Why or why not? Also, "paint" a dab of fingernail polish on the surface of a leaf, allow to dry, peel off and observe under a microscope. Are all the stomata open or closed? Why? 2. Observe trichomes...
Question 2 (1 point) All of the following are primary roles of plant epidermal cells EXCEPT: changing the shaps of cells in response to osmosis capturing Co, and doing photosynthesis regulating the movement of substances in and out of the leaf secreting a waxy cuticle Question 3 (1 point) Assuming the stomata are open to the same degree, the rate of transpiration should on a humid day compared with a dry day because the H2O vapor concentration difference from the...

True or False Counterpoint is a term that describes a technique in which lines that are in reality parallel and horizontal are represented as converging diagonals.
Circle only the statement that is false for each question: 1. The cells of withered plants have (a) lost H2O (c) taken salt (b) lost turgidity (d) been plasmolysed 2. Stems & leaves of wilted plants have: (a) become flaccid (c) taken salt (b) lost their turgidity 3. By placing these plants in pure H2O, they resume their turgidity because (a) H2O enters the cells by osmosis (b) salt in the cells goes out by washing H2O 4. This movement...
