Plant Science Final A1 Flashcards
1,A root that grows from other tissues besides root tissue is:
adventitious roots
2,Area of Meristematic growth located in the leaf axis between the node and the stem
cambium
3,The flow of organelles that can be clearly seen in active leaf cells with a microscope is called:
cyclosis
4,An area in the root that increases the growth of the roots, it is said that these dividing cells can propel the root as much as 0.08” per day
root apical meristem
5,A tap root is defined as a dominant root that develops downward, an example would be:
carrot
6,Area of growth that is refereed to as the termini and is the origin of all growth in the plant___
apical meristem
7,This structure in cells is made up of channels and pits that connect from cell and allow the flow of water and nutrients to pass between cells.
plasmodesmata
8,The organelles that have two membranes are:
mitochondria and chloroplasts
9,Agronomy and horticulture are:
plant sciences
10,Growth that increases the height of the plant originates from the___
apical meristem
11,Cultivation is:
preparing land for crops
12,The main function of these structures are to support and elevate the leaves, flowers and the fruit; also a delivery system for minerals and water. They also have a minor role in photosynthesis in some species
stem
13,Vascular Cambium is meristematic tissue that gives rise to__
secondary growth
14,Epidermis is
outermost layer of cells in a plant
15,The main function of these structures are to anchor the plant and absorb water and minerals
roots
16,A corn plant would be an examples of a____
monocot
17,Tissue that is comprised of the xylem and phloem and is used to transport water, minerals and sugars in the plant
vascular tissue
18,The theory of endosymbiosis gives an explanatoin as to how cells came to have the following
origin of mitochondria and chloroplasts
19,The portion of the stem that is in-between nodes
internode
20,The word cultivar refers to:
cultivated variety
21,The girth or circumference of the stem increases due to divisions in the___
cambium
22,A soybean plant would be an example of a ____
dicot
23,A type of stem that has thick tissie and generally lives more than two years, an example is trees and shrubs
woody
24,Tissue tat makes up the bulk of the plant
ground tissue
