CAMPBELL BIOLOGY 12TH EDITION
EXAM 4 CHAPTER 35-37,39 QUESTIONS
WITH COMPLETE SOLUTIONS
No-till agriculture - answer-plowing technique that minimally disturbs the soil, thereby
reducing soil loss.

Sieve plate - answer-end wall in a sieve-tube element, which facilitates the flow of
phloem sap in angiosperm sieve tubes.

Apical meristem - answer-localized region at growing tip of a plant body where one or
more cells divide repeatedly. The dividing cells enable the plant to grow in length.

Macronutrient - answer-essential element that an organism requires in large amounts

Crop rotation - answer-growing different crops in succession on same land to preserve
productive capacity of soil

Determinate growth - answer-a type of growth characteristic of most animals and some
plant organs, in which growth stops after a certain size is reached.

Pericycle - answer-the outermost layer of the vascular cylinder of a root, where lateral
roots sprout from.

Sugar sink - answer-a plant organ that is a net consumer or storer of sugar. Growing
roots, shoot tips, stems, and fruits are sugar sinks supplied by phloem.

Phloem sap - answer-the sugar-rich solution carried through a plant's sieve tubes.

Cell - answer-fundamental unit of life

Tissue - answer-group of cells that perform specialized function

Organ - answer-group of tissues that work together to perform particular functions

Photosynthate - answer-sugar and other carbohydrates made during photosynthesis

Root - answer-an organ in vascular plants that anchors the plant and enables it to
absorb water and minerals from the soil.

Primary root - answer-originates in seed embryo and 1st root/organ to emerge from
germinating seed.

, Lateral roots - answer-forms after the primary root branches and enhances roots
function

Taproot - answer-a main vertical root that develops from an embryonic root and gives
rise to lateral (branch) roots, forms from primary root.

Fibrous root system - answer-a root system common to monocots consisting of a mat of
thin roots spreading out below the soil surface.

Adventitious - answer-when plant organ grows in unusual location

Root hairs - answer-tiny hair-like extensions that increase the surface area of the root
allowing it to absorbs more water and nurtients

Mycorrhizal associations - answer-symbiotic interactions with soil fungi that increase a
plant's ability to absorb minerals

Stem - answer-a vascular plant organ consisting of an alternating system of nodes and
internodes that support the leaves and reproductive structures.

Nodes - answer-the points at which leaves are attached

Internode - answer-a segment of a plant stem between the points where leaves are
attached.

Apical bud - answer-located near the shoot tip and causes elongation of a young shoot

Axillary bud - answer-a structure that has the potential to form a lateral shoot, or branch.
The bud appears in the angle formed between a leaf and a stem.

Tropism - answer-a growth response that results in the curvature of whole plant organs
toward or away from stimuli owing to differential rates of cell elongation.

Root cap - answer-a cone of cells at the tip of a plant root that protects the apical
meristem.

Stele - answer-the vascular tissue of a stem or root.

Biotic - answer-describes living factors in the environment.

Cation exchange - answer-a process in which positively charged minerals are made
available to a plant when hydrogen ions in the soil displace mineral ions from the clay
particles.

Sustainable agriculture - answer-long-term productive farming methods that are
environmentally safe.
