Biology 1001 Exam 4 Study guide. LSUE Marcel QUESTIONS
WITH ANSWERS RATED A+
Monocot floral parts usually occur in multiples of - three.
What is the node of a plant stem? - the point of leaf attachment
In general, plant dermal tissues are found - at the outer surface of a plant.
Which type of vascular tissue cell in a plant is dead at maturity? - vessel elements
Photosynthesis occurs in which type of plant tissue? - parenchyma
Tracheids function in - water conduction.
Which cells provide flexible support to the growing parts of plants? - collenchyma cells
The growth phase responsible for lengthening roots takes place through/in what location? - cell
elongation behind the root tip.
Most trees and shrubs continue to grow year after year. Such plants are known as - perennials.
A vascular cambium cell divides to produce an inner and an outer daughter cell. Which outcome
represents the probable fate of these cells? - The inner cell will differentiate into xylem, and the
outer cell will differentiate into phloem.
Multicellular gametophytes are the product of spores from - ovules and anthers.
How does the sperm of an angiosperm reach the egg? - via the pollen tube that grows from the
pollen grain through the carpel tissues to the ovule
Which statement about germination is false? - The germination of a seed represents the
beginning of life.
Which plant parts commonly contribute to asexual reproduction? - roots
.What is an advantage of cloning horticultural crops rather than using sexual propagation to grow
them? - Cloning plants allows for large production of plants with minimal effort and expense.
Foreign genes can be inserted into a single plant cell that is then cultured to produce - a
genetically modified plant.
Clusters of light-gathering pigments in a photosystem - pass energy to the reaction center.
