Water is essential for life. Its special properties make water the single most important molecule in plant life. Which of the following properties of water enables it to move from the roots to the leaves of plants?
Water expands as it freezes
Water is an excellent solvent
Water exhibits cohesive behavior
Water is able to moderate temperatures
From which flower part does structure A in the diagram below develop?
stamen
petal
anther
ovary
The diagram below represents a change in guard cells that open and close pores in a plant. This change directly helps to...
increase heterotrophic nutrition
absorb minerals
regulate water loss
reduce seed production
Which phrase, if placed in box X, would correctly complete the flowchart shown below?
Increased use of starch in root cells
Increased concentration of glucose in leaf cells
Decreased ATP in root cells
Decreased concentration of oxygen in leaf cells
The green aquatic plant represented in the diagram below was exposed to light for several hours. Which gas would most likely be found in the greatest amount in the bubbles?
oxygen
ozone
nitrogen
carbon dioxide
Base your answer to the following question on the diagram below which represents a cross section of part of a leaf. Which life functions are directly regulated through feedback mechanisms associated with the actions of the structures labeled X?
excretion and immunity
digestion and coordination
circulation and reproduction
respiration and photosynthesis
The diagram below shows a microscopic view of the lower epidermis of a maple leaf. The diagram below shows a microscopic view of the lower epidermis of a maple leaf.
a stomate
xylem tissue
a lenticel
phloem tissue
The diagram below represents specialized cells in the surface of the leaf of a green plant.The main function of these cells is to
change the size of the stomate to regulate water loss
close the stomate to keep dust and dirt out of the leaf
directly provide leaf cells with the water involved in photosynthesis
allow newly formed glucose to be released from the leaf
The exchange of oxygen and carbon dioxide between internal leaf cells and the external environment will occur most efficiently if
the surfaces of these cells are dry and the stomates are closed
these cells are dry and the stomates are open
the surfaces of these cells are moist and the stomates are open
these cells are moist and the stomates are closed
The diagram below illustrates the movement of materials involved in a process that is vital for the energy needs of organisms. The process illustrated occurs within
chloroplasts
mitochondria
ribosomes
vacuoles
Terrestrial plants have stomata on the surface of their leaves. Stomata are surrounded by two guard cells that change shape in response to environmental factors and open or close the stoma. Which of the following best explains how the structure of the leaf is used in processes that occur in plants?
Water enters the plant through the surface of the leaf for transpiration
Gases for photosynthesis are exchanged through the surface of the leaf.
Energy for cellular reproduction is absorbed through the surface of the leaf
Carbon dioxide enters the plant through the surface of the leaf for cellular reproduction
If the xylem in a young tree is damaged, which process is FIRST affected?
performing photosynthesis
transporting sugar to the roots
transporting water to the leaves
absorbing water from the soil
What is the main function of leaves?
Leaves provide support for growth and a place to store food.
Leaves provide a place for photosynthesis to occur.
Leaves absorb water and minerals and transport nutrients to the stem.
Leaves create a barrier that prevents water in the plant's tissues from evaporating.
The cambuim is a section of cells in a plant that can become either part of the xylem or phloem, depending on the growth and needs of the plant. If the cambium of a particular plant was damaged, what would be the most likely effect on the plant?
The plant would lose its ability to carry out photosynthesis.
the plant would have uncontrolled growth.
The plant would not experience any change in physiology.
The plant would not be able to transport nutrients and water.
The diagram below shows a cross section of a plant leaf. How does the structure marked X contribute to the survival of the plant?
It allows the intake of gases necessary for photosynthesis.
It allows the intake of minerals necessary for plant growth.
It allows the intake of sunlight necessary for ATP production.
It allows the intake of sugars necessary for plant reproduction.
Which statement describes the role of flowers in plant survival?
Flowers can absorb carbon dioxide for sugar production.
Flowers produce oxygen through cellular respiration.
Flowers contain cells that carry out photosynthesis.
Flowers contain cells that produce gametes.
What is the main purpose of seeds in plants that have them?
To protect and distribute the zygote.
To entice animals to eat the plant.
To be fertilized by other plants.
The diagram below represents a flower, the reproductive structure of some plants. Most flowers have both male and female structures for fertilization and reproduction. Which structure is represented by the letter A in the diagram above?
the stamen, a male structure which produces pollen
the pistol, a female structure which collects pollen and passes it to the ovary
the sepal, a modified leaf used for protection of the flower
the petals, decorative structures which attract pollinators
What part will become the fruit?
A
B
C
D
E
