test Ch 23 Plant Structure and Function Chapter Test Review Flashcards

1159813773	In angiosperms , xylem consists of tracheids and...	vessel elements	1
1159813774	Vascular tissue in plants consists of	xylem and phloem	2
1159813775	To observe mitosis, which part of the plant should a student examine under a compound microscope?	tip of the shoot and tip of the roots	3
1159813776	The layer of cells that encloses the vascular tissue in the central region of a root is the	endodermis	4
1159813777	The vascular cylinder of a root consists of	xylem and phloem	5
1159813778	Root pressure is produced where and by what?	Vascular cylinder by active transport	6
1159813779	What are the three main functions of stems?	Carries water and nutrients between stems and leaves, produce leaves, branches and flowers, hold leaves up to the sun for photosynthesis to occur, and transport substances throughout the plant.	7
1159813780	Many cacti, such as saguaros and barrel cacti, have large stems and no leaves. What function of the leaves is taken on by the stems of such cacti?	Photosynthesis	8
1159813781	During primary growth, a stem...	grows taller and increases in length	9
1159813782	Oxygen and carbon dioxide move in and out of the leaf through the	stomata (see diagram on worksheet)	10
1159813783	In Figure 23-1, water pressure in the ........... is high.	guard cells	11
1159813784	In many plants, stomata are found only on the lower surface of the leaf. The most likely explanation for this fact is that....	water loss will be less on the lower shaded surface than in the direct sun.	12
1159813785	The attraction of water molecules to other kinds of molecules (like those in glass and plastic for example) is called...	adhesion	13
1159813786	What are the parts of the pressure-flow hypothesis?	the movement of water into a nutrient rich region of the phloem decreases the pressure in that region.	14
1159813787	Ground tissue is found in what parts of a plant?	Stem, root, and leaf	15
1159813788	In plants, the main organs in which photosynthesis takes place are	leaves	16
1159813789	Root hairs are made up of ........... tissue.	dermal	17
1159813790	In plants the opening and closing of stomata balance water loss with the need for	sun and CO2 (carbon dioxide)	18
1159813791	............ at the tips of stems and roots produce rapid growth in plants	Meristems	19
1159813792	In Figure 23-2, structure B is the ............, which includes a waterproof zone called the ................	endodermis......casparian strip	20
1159813793	In xylem and phloem, the cells that keep their nuclei and organelles are the....	companion cells.	21
1159813794	Contrast the flow of materials in xylem and phloem?	Xylem: water....up Phloem: Nutrients....up and down	22
1159813795	A scientist discovers a new plant. She notes that the plant forms wood as it becomes taller. Did the scientist discover a monocot or a dicot? Explain.	Dicot because wood is the secondary growth of dicots as monocots only produce primary growth.	23
1159813796	During a very hot, sunny day, are stomata likely to be open or closed? Explain	Closed so they don't lose water.	24
