Just like vertebrate animals, plants possess excretory systems. One way that plants excrete waste products is by opening pores in the surfaces of their leaves. These pores, called stomata, help a plant maintain homeostasis by allowing the plant to —
collect substances such as ammonia and salt.
release substances such as oxygen and water.
manufacture substances such as chlorophyll and resin.
destroy substances such as sap and uric acid.
Students set up a controlled experiment by growing the same type of seedlings in two different locations. After a period of time, the students observed the seedlings and recorded their observations in the table shown.
What caused the shoots of the seedlings on the windowsill to bend toward the window?
Hormones produced in response to a light stimulus
Sugars produced in response to a gravity stimulus
Carbon dioxide produced in response to a water stimulus
Water produced in response to a nitrogen stimulus
The underside of a leaf contains tiny pores called stomata. These pores lie next to specialized guard cells. Which of the following is NOT helped by the structure of the stomata and the specialized guard cells?
The plants release of water during transpiration.
The plants capture of pollen for sexual reproduction.
The plants absorption of carbon dioxide for photosynthesis.
The plants flow of nutrients from the roots to the rest of the plant.
The diagram shows the reproductive system of a plant.
Which of the following best describes the interaction that occurs between a plant’s reproductive parts during self-fertilization?
A.
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 style 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.
Pollen is released from the stigma and is transferred to the anther. A pollen tube grows down from the anther through the filament and fuses with the ovule, where the sperm fertilizes the egg.
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
transpiration
phototropism
photosynthesis
How do plant structures work together to maintain a balance of water inside the plant?
Shoots control water absorption, and roots control water evaporation.
Roots control water absorption, and leaves control water evaporation.
Leaves control water absorption, and roots control water evaporation.
Roots control water absorption, and shoots control water evaporation.
A flower that has both male and female reproductive structures is shown. Which statement best describes an interaction that will allow a flowering plant to reproduce by self-pollination?
An anther is transferred from a filament to another filament within the same flower.
An ovule is transferred from the ovary to a petal on a different flower
A pollen grain is transferred from an anther to the stigma of the same flower.
An ovary is transferred from a flower on one plant to a flower on a different plant.
The structures of the dermal and vascular systems work together to transport and provide materials essential for photosynthesis. Which statement correctly identifies how they work together?
The xylem transports glucose to the roots for storage, and the phloem allows oxygen to enter the leaf.
The xylem transports water from the roots, and the stomata allows carbon dioxide to enter the leaf.
The phloem transports water for transpiration, and the stomata allows oxygen to enter the leaf.
The stomata transports glucose from the roots, and the phloem allows carbon dioxide to enter the leaf.
A climbing vine is able to coil around an object it touches. This occurs because the hormone auxin causes the cells on the side of the vine not touching the object to grow faster than the cells on the side of the vine touching the object.
The response that causes the vine to climb is known as ―
gravitropism
hydrotropism
phototropism
thigmotropism
A student conducted an experiment investigating responses in plants. First, she placed a plant upright and noticed that the stems grew upward. Then, she turned the plant on its side and found that the stems bent so that they still grew upward.This response is known as ―
gravitropism
hydrotropism
phototropism
thigmotropism
The primary reproductive structures of a lily are labeled on the illustration.
How do the labeled structures interact during plant reproduction?
Pollen from the Y structure transfers to the X structure to deliver sperm to the ovules
Pollen from the X structure transfers to the Y structure to deliver sperm to the ovules.
Eggs from the Y structure transfer to the X structure to deliver ovules to the pollen.
Eggs from the X structure transfer to the Y structure to deliver ovules to the pollen.
Which of the following are correct functions of the digestive system? Select TWO correct answers
The digestive system absorbs nutrients the body can use for energy.
The digestive system transports nutrients throughout the body.
The digestive system filters blood and removes wastes from the body.
The digestive system regulates body activities using hormones.
The digestive system breaks down the foods we eat into smaller substances.
Which systems work together to make the diaphragm move which increases the volume of the thoracic cavity during breathing?
Muscular and respiratory
Skeletal and endocrine
Endocrine and respiratory
Integumentary and muscular
When the skin comes in contact with an irritant, receptors in the skin send signals to the spinal cord. The signal is then sent to the brain for processing, and the individual begins to scratch the affected area.
Which two systems are most likely interacting when a person experiences itching caused by a skin irritant?
Circulatory and excretory
Integumentary and nervous
Digestive and muscular
Respiratory and lymphatic
Animal body systems often coordinate their actions to carry out specific functions for the whole animal. Which of these correctly describes the interaction of two biological systems for a specific purpose in the human body?
