Phosphorus is a plant nutrient that is found in the soil and is important in nucleic acids, phospholipids, coenzymes, DNA, NADP, and ATP in a plant.
Phosphorus helps to decompose carbohydrates that a plant produces in photosynthesis, is used in protein synthesis, and does many other processes that a plant needs to grow and reproduce.
Which statement correctly shows how the roots and shoot systems of a plant work together to allow phosphorus to get from the soil to the plant?
The plant absorbs phosphorus in the roots and transports it to the plant’s tissues by the shoot system.
Phosphorus is absorbed in the leaves and is transported to the roots via the shoot system.
The shoot system transports phosphorus to the roots in a process called transpiration.
The roots absorb phosphorus and make sugars that are taken to the leaves, where the stomata release gases to the environment.
Which vascular tissue is responsible for carrying water from the roots to the rest of the plant?
phloem
meristematic
xylem
dermal
What are the two systems that make up the body of a plant?
Roots and Stem
Roots and Shoot
Stems and Leaves
Chloroplasts and Leaves
Which vascular tissue is responsible for moving food in the form of glucose, to all parts of a plant?
Xylem
Meristem
Ground tissue
Phloem
A plant responding to a "touch stimulus" is called?
Phototropism
Heliotropism
Geotropism
Thigmotropism
Which of the following is NOT a form of asexual reproduction in plants?
Runners
Side Shoots
Flowers
Bulbs
A student performs an experiment where she puts a plant by a window and observes the plant each day for a week. Below is a picture of the plant on day 1 and day 5.
At the end of the week, the student makes observations and concludes that the reason the plant has moved in the direction of the window is because of
thigmotropism
positive gravitropism
phototropism
negative gravitropism
The outermost layer of plant stems in dicotyledons consists of epidermal cells and guard cells that surround openings called stomata. The epidermal cells are usually covered with a waterproof layer that provides protection from injury and water loss. The stomata allow gas exchange. The epidermal cells and stomata have functions similar to those of which two human body systems?
Cardiovascular and integumentary
Skeletal and respiratory
Cardiovascular and skeletal
Integumentary and respiratory
Some students are instructed to put a celery stalk in a red dye solution for a lab activity. First the students carefully cut the bottom of the stalk with a scalpel. Then they put the stalk in the beaker with the solution and place the beaker on a shelf in the lab room. The next day they check the stalk and make observations. The students note that the leaves at the end of the stalk have changed color from green to red. The students cut across the celery stalk and use a hand lens to see that the small tube openings along the edge of the celery stalk are also red. The cross section is shown below.
How do the plant systems work together to make this movement of liquid possible?
The roots lose water vapor to the soil, and the stem loses water vapor through the leaves.
The roots absorb their own water and minerals, while the stem absorbs its water and minerals through the leaves.
The roots anchor the plant in the soil, and the stem holds the leaves up.
The roots absorb water and minerals and move them up to the stem, while the stem moves food produced in the leaves down to the roots in tiny tubes.
Plants called sundews have rounded green leaves with many hair-like structures. The ends of these structures contain enzymes in a sticky liquid that looks like nectar or moisture, as shown in the picture. The hairs do not
react to dust or nonliving material but will bend inward when insects get caught in the sticky liquid. Sundews digest trapped insects over a period of a few days.
Based on this information, what functions do the specialized leaves of sundews perform?
Provide water to the plant and perform photosynthesis
Respond to stimuli and anchor the plant
Release pollen to insects and perform photosynthesis
Provide nutrients to the plant and respond to stimuli
Plant hormones serve as chemical messengers between cells and tissues. Auxin is a plant hormone that causes the cells on the shady side of a plant shoot to elongate. The response enabled by auxin is known as —
geotropism
phototropism
photosynthesis
transpiration
Changes in water pressure within guard cells cause the cells to open or close the stoma. This response helps the plant maintain homeostasis by —
stabilizing the plant’s temperature through the evaporation of water
regulating the amount of water the plant loses during transpiration
allowing oxygen needed for photosynthesis to enter the plant
enabling the plant to release more carbon dioxide at night for photosynthesis
Toxoplasmosis is an infection producing brain lesions caused by the parasitic protozoan Toxoplasma gondii. Mice with their gonads removed are more resistant to T. gondii and develop very few lesions on their brain tissue. The graph shows the results of a scientific study of normal adult mice infected with T. gondii.
Which systems most likely interact and cause the severity of infections to vary?
Muscular and skeletal
Nervous and integumentary
Immune and endocrine
Excretory and respiratory
The diagram shows the internal feedback mechanism that maintains blood-calcium (Ca2+) homeostasis.
If a person has a blood-calcium (Ca2+) level of 8 mg/100 mL of blood, which of the following mechanisms does the body use to maintain blood-calcium homeostasis?
The kidneys take up more Ca2+ and release vitamin D.
The bones release Ca2+
The intestines increase reabsorption of Ca2+.

Scientists studying illnesses caused by chemically contaminated food conduct research to minimize the effects of these diseases on society. These chemicals harm the body through interactions between the digestive system and the immune system. Scientists conducting this research are likely to describe which of these interactions between the digestive and immune systems?
Chemicals enter the digestive system through contaminated foods. Once in the body, the chemical contaminants impair the body’s ability to fight off infectious diseases.
The immune system transforms the chemicals in the contaminated foods into harmless chemicals. These harmless chemicals are then broken down by the digestive system.
Chemicals enter the immune system through a break in the skin. The chemical contamination is then passed to the digestive system by the circulatory system.
When contaminated foods are eaten, the immune system prevents the chemicals from entering the digestive system.
Which of the following correctly describes an interaction that occurs between two body systems of a rabbit that helps the rabbit out run a pursuing coyote?
The endocrine system releases hormones that prepare the immune system to deal with possible injuries.
The digestive system increases the rate of digestion, and the excretory system ceases to provide tissues with more nutrients.
The skeletal system releases additional calcium, and the circulatory system retains more sodium in the blood to provide muscles with ions for contraction.
The respiratory system increases the breathing rate, and the circulatory system increases blood pressure to provide tissues with more oxygen.
The osmoregulation process is shown below.
This process is an example of which of the following?
The role of the endocrine system in increasing the oxygen content of red blood cells
Control of urine production by the parasympathetic nervous system
Maintenance of homeostasis by a feedback mechanism
Disruption of homeostasis by exercise
The layer of cells that cover and protect the plant.
