Based on this information, the student can conclude that boron is absorbed by plant roots from soil and then —
What is the vascular tissue that carries water throughout a plant?
phloem
seedling
xylem
______________, pores on leaves through which plants lose water and exchange carbon dioxide and oxygen.
stomata
seed
stem
The body of a plant is made up of organs called roots, ________, and leaves.
vacuole
stems
cones
What does the reproductive system for a plant consist of?
flower and fruit
xylem and phloem
chloroplast and chlorophyll
What is the function of the plant organelle called the vacuole?
The vacuole stores water, nutrients, and waste.
The vacuole produces proteins.
The vacuole stores DNA.
_____________________ is a vascular tissue that carries sugars and other foods throughout a plant.
stems
phloem
roots
xylem
What is the main function of the chloroplast cell organelle?
The chloroplast organelle's main function is to produce green pigment.
The chloroplast organelle's main function is to convert light energy into chemical energy through photosynthesis.
The chloroplast organelle's main function is to produce DNA
___________________________ is growth that happens in organisms in response to light, such as a stem bending toward a light source.
transpiration
gravitropism
phototropism
Which homeostasis mechanism is the plant version of an animal drinking when it gets thirsty?
A plant's growth response toward light
A plant's growth response to gravitation
A plant wilting when the soil dries out
A plant making sugar through photosynthesis
___________________________ is the loss of water through the pores on plant leaves.
respiration
stomata
transpiration
Germination occurs when the plant embryo uses stored food and begins to grow again. The force of the growing embryo causes it to push out of the seed. This is known as ___________________.
emergence of a seedling
tropism
photoperiodism
dormancy
The diagram show the reproductive system of a plant. Which of the following best describes the interaction that occurs between a plants reproductive arts during fertilization?
Pollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches the filament, where the sperm fertilizes the egg.
Pollen moves from the ovule up through the stule and is released from the stigma. The pollen is transferred to the anther, where the sperm fertilizes the egg.
Pollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches an ovule within the ovary, where the sperm fertilizes the egg.

Structures represented in the illustration below are found in the lower epidermis of a plant leaf. The illustration at right shows the response to a certain environmental condition. The response represented in the illustration would most likely be caused by --
a reduced supply of oxygen
long periods of rainfall
high concentrations of glucose
little available water
Invasive plant species affect the interaction of living and nonliving components of an ecosystem, so the removal of invasive plants is often necessary. The goal of most plant-control methods is to disrupt or inhibit the function off different plant systems. For example, insects can be used chew through roots in order to reduce a plant's ability to absorb water. Which of these function would be most immediately affected by a reduction in water uptake by roots ?
disease resistance
seed dispersal
sunlight absorption
photosynthesis
What is the function of a root?
Where pollination occurs
Absorbs water and nutrients for the plant
Produces food
What is the functions of a stem?
Absorbs water and nutrients
Produces pollen
Transports water and nutrients
What type of root has one main root that grows deep in the ground with a few smaller side roots?
Aerial roots
Fibrous roots
Prop roots
Taproots
The plant cuticle is a waxy coating on a plant that keeps water from evaporating.
True
False
