Front (Term) Which of the following is not a function of the stem in most plants? |
Back (Definition) Serves as the primary site of photosynthesis in the plant (a similar question was online and it's from a source where he finds some of the questions so I'm going with it) |
|
|
Front (Term) A plant physiologist is studying the structures is found on plants which increase the absorption of capacity of the roots. Based on this information you would conclude that he or she is studying which of the following structures? |
Back (Definition) Root hairs |
|
|
Front (Term) A biologist is studying an unknown species of plant and observed the following characteristics: The root xylem and phloem are in a ring, The vascular bundles are scattered throughout the stem, and the leaf veins form parallel pattern. Based on these observations that biologists could safely conclude that the plant is |
Back (Definition) Monocot |
|
|
Which of the following is not a function of the apical meristem of plants? |
Can't find the actual answer so here's what it does do: Epidermal tissue forms the outer protective covering of the plant, ground tissue fills the interior of the plant and serves metabolic functions, vascular tissue contains xylem and phloem |
|
|
Front (Term) Which of these associations is incorrect? |
Back (Definition) Here is what they do. |
|
|
If you were studying the rate of gas exchange that takes place in the leaves of plants you would be studying which of the following? |
Respiration |
|

|
|
Woody plants have large trunks composed mostly of |
Secondary xylem |
|
|
What is the benefit of a plant have a new mutualistic fungus on or in its roots |
Fungus increases the surface area available for mineral and water up and breaks down organic matter in soil |
|
|
Water is transported in vascular plants through which of the following |
Xylem |
|
|
Which of the following is responsible for providing proteins to the sieve tube members in plants |
Companion cells |
|
|
Which of the following belong to the phloem |
Sieve tubes and companion cells |
|
|
After an injury or pruning some plants appear to bleed as water exudes from the site. This is mostly due to which of the following |
Guttation |
|
|
Which of the following gives the water column in the stem of plants extra strength and prevents the water from slipping back |
Adhesion |
|
|
If you were studying the mechanism which moves water up the stem you would be interested in all of the following except |
Phloem |
|
|
In the root, water enters the xylem primarily by which of the following |
Aquaporins |
|
|
Guard cells open a stomata because od |
Water loss and gas exchange and presence of light |
|
|
Sugar is produced in _____ and then moves to ______ |
Leaves; roots |
|
|
Sugar has to be made |
Sugar has to be made |
|
|
If you were studying the waterproofing strip which surrounds the cells of the endodermis and forces water to pass through the cells of the endodermis instead of around them, you would be studying |
Casparian strip |
|
|
Which statement about mycorrhizae is incorrect |
It is the symbiotic association between fungus and roots of a vascular plant |
|
|
What is the correct order in the signal transduction pathway |
Reception, transduction, response |
|
|
If you were to play some auxin on one side of a tipless coleoptile, what would be the result |
The shoot would bend away from the auxin |
|
|
If you were studying a growth promoting hormones that brings about internode elongation of the stem cells you would be studying which of the following |
Gibberellins |
|
|
The dropping of leaves, fruits and flowers is called |
Abscission |
|
|
When the plant tracks the sun by means of turgor pressure changes in the petiole it is called |
Heliotropism |
|
|
Which of the following would cause a leave cell to become turgid |
Too much water |
|
|
The plant physiologist study plans which flower in the day length is shorter than a critical length. The plant physiologist is studying these types of plants |
Short day plants |
|
|
Which of the following is false with respect to the phytochrome receptor |
Two identical proteins, Active PFR confirmation moves to nucleus, binds to transcription factors can turn off and on genes, promoting seed germination, inhibiting shoot elongation and normal seedling growth |
|
|
If I biologist is studying chemical Defense in plants, he or she would most likely be studying which of the following |
Chemotropism |
|
|
Studying the male parts of a flower |
Stamen - filament and anther |
|
|
Part of the flower used for catching pollen |
Stigma |
|
|
Which of the following structures will automatically become the seed in plants |
Fruit |
|
|
Alternation of generations and flowering plants includes the formation of a |
Sporophyte generation |
|
|
The male gametophyte and flowering plants will be found within the |
Pollen grain |
|
|
The pollen grain contains the |
Male gametes - haploid and contain larger vegetative cell which has a smaller germ cell |
|
|
If you were studying the flower structure which develops within the female gametophyte you would be studying which of the following |
Ovule |
|
|
Once the pollen has been transferred from the male to the female how do the sperm get to the egg |
Pollen grain develops pollen tube that goes toward the ovary. Pollen tube grows into the ovules inside the ovary and once the sperm travels down the pollen tube one will fertilize the egg |
|
|
