Example Questions
Example Question #864 : Ap Biology
Which of the following best describes where parenchyma cells can be found in plants?
Leaves
Stems
Roots
All of these
All of these
Parenchyma cells make up a type of ground tissue in plants. Parenchyma cells compose most of the soft tissues in plants including leaves, roots, stems, and seeds. The functions of parenchyma cells include photosynthesis, storage, and wound repair.
Example Question #6 : Understanding Other Plant Macrostructures
Which of the following is true regarding meristem tissue in plants?
There is a shoot and root apical meristem
It is present in areas of growth
All of these
It contains undifferentiated cells
All of these
Meristem tissue contains undifferentiated cells and allows for plant growth. Apical meristems are found in areas of growth, which include the shoot and roots—cells in these tissues divide rapidly.
Example Question #1 : Understanding Other Plant Macrostructures
Which of the following best describes the location of the vascular cambium in plants?
In the tips of leaves
In the periderm
Between the xylem and phloem
None of these
Between the xylem and phloem
The vascular cambium is a type of secondary meristem tissue located between the xylem and phloem of the stems and roots. Secondary meristem tissues are responsible for lateral growth; more specifically, the vascular cambium is responsible for secondary xylem and phloem development.
Example Question #7 : Understanding Other Plant Macrostructures
Which of the following is not true regarding the cork cambium?
It is a type of secondary meristem
It is located in the periderm
It is the source of secondary xylem and phloem growth
It is the source of secondary epidermis growth
It is the source of secondary xylem and phloem growth
The cork cambium is a type of secondary meristem tissue found in the periderm. Cork cambium controls lateral growth; specifically, it is the source of secondary epidermis growth.
Example Question #8 : Understanding Other Plant Macrostructures
Which of the following best describes what annual growth rings in trees represent?
New primary xylem growth
New cork cambium growth
New vascular cambium growth
New primary phloem growth
New vascular cambium growth
Cutting into the trunk of a tree to create a horizontal cross section reveals rings, called annual growth rings. These rings show new vascular cambium growth over the course of a year. Differences in growth speed change the size of the growth rings.
Example Question #62 : Plant Biology
Which of the following best describes the location of the receptacle on an angiosperm?
Inside the ovary
At the top of the stem
Attached to the anther
At the top of the ovary
At the top of the stem
The receptacle is the part of an angiosperm out of which the flower grows; thus, the receptacle is at the top of the stem.
Example Question #871 : Ap Biology
Which of the following is contained in the carpel?
Stamen
Anther
Flower
Ovules
Ovules
The carpel is a part of the female angiosperm reproductive system. The carpel includes the ovary, ovules, style, and stigma. Flowers may have several carpels clustered into a pistil.
Example Question #871 : Ap Biology
Which of the following is produced by stamens in angiosperms?
Pollen
Seeds
Ovules
Sap
Pollen
Stamens are a part of the male reproductive system in angiosperms. Stamens have a filament and an anther, which is attached to the top of the filament. Anthers produce pollen through the process of meiosis.
Example Question #61 : Plant Biology
Which of the following best describes the function of the sepal in angiosperms?
Attracts pollinators
Production of pollen
Protection of the flower when it is still in the bud
Houses ovules awaiting fertilization
Protection of the flower when it is still in the bud
The sepal is a protective structure in angiosperms. When the flower is still in the bud, the sepal offers protection and later supports the bloom.
Example Question #1 : Plant Functions
Which plant tissue system is similar to the human circulatory system?
Dermal tissue
Sclerenchyma
Vascular tissue
Ground tissue
Vascular cambium
Vascular tissue
A plant's vascular tissues transport nutrients throughout the plant, just as the circulatory system transports nutrients throughout human bodies. While blood is the primary solvent for nutrients in humans, water is the primary solvent for nutrients in plants. Animals, however, use blood pressure to propel nutrients throughout the body while plants use gravity and the cohesive properties of water to transport nutrients.
The two primary types of plant vascular tissue are xylem, which transports water, and phloem, which transports organic molecules like glucose.
