Introduction:
An imaginary line where somethingcouldbe folded in half and one half would match the other half is called symmetry. There are three types of symmetry in biology. These are bilateral symmetry, radial symmetry and asymmetrical. In bilateral symmetry, the body of the object is divided into halves that form mirror images. If more than one line is drawn to divide an animal or a plant in half, and each of these lines run through a central point on the animal or plant, then the animal has radial symmetry. If an animal or plant has no symmetry at all, it is called asymmetrical. Apical is related to shoots, stems and the upward part of the plant. Basal is the bottom part of the plants related to the roots of others.

- Which of the following statements about age gradients within the plant body is FALSE? Select one: a. Age gradients within the plant body include an apical-basal gradient where the youngest cells are near the apices (tips of shoots and roots). b. Age gradients within the plant body reflect the plant cells’ lack of mobility due to their shared walls. c. Phloem is oldest toward the outermost cell layers of the tree trunk and xylem is oldest toward the innermost cell layers of a tree trunk. d. All of the statements are true. e. Age gradients within the plant cells include walls that are youngest immediately adjacent to the plasma membrane and progressively older toward the middle lamella.arrow_forwardRelate the structure of an angiosperm leaf to each of the following:- Adaptations for photosynthesis and food storage.- Adaptations for food translocation and water transport.- Specialized adaptations to a desert environment.arrow_forwardWhich of the following is the defining feature of true vascular tissue in plants? Group of answer choices the presence of lignin tracheids vessel elements the presence of cellulose none of the abovearrow_forward
- For the following descriptions - indicate whether they describe a monocot or a eudicot. -parallel veins in leaves -root system is a taproot -flower organs in groups of 4 or 5 -vascular bundles scattered in the stem -capable of woody growth -pollen grain with three openings -embryo with one cotyledonarrow_forwardCan you define the following plant terms; - Apical dominance - Symplastarrow_forwardWhich of the following statements about age gradients within the plant body is FALSE?arrow_forward
- Create a table to compare and contrast the following sets of terms. The table should define each term and outline the significance of each for plant function. Monocot root system: Dicot root system Root hair: Lateral root Bundle sheath: Kranz anatomy Low specific leaf area: High specific leaf area Monopodial branching: Sympodial branchingarrow_forwardIn many monocots such as grasses and irises, foliage leaves have a shape quite different from that of eudicot leaves. Their shape tends to be (circle two: long, short, tapering, wide). They lack a petiole and instead have a_________________ ______________________ that wraps around the stem. Name three monocots that have leaves that are unusual in that they appear to have petioles and laminas.arrow_forwardWhich of the following plant tissue types can play a role in structurally supporting the plant? Select all that apply Dermal Vascular Groundarrow_forward
- Plants are classified into three types based on water availability in its habitat. What are these types? Cite at least one leaf adaptation (morphological/ anatomical) on each type.arrow_forwardWhich of the following is not correct concerning plant xylem? The fluid (sap) in the xylem transports sperm and eggs throughout the plant. The fluid (sap) in the xylem transports water and ions. The fluid (sap) of the xylem moves from the roots toward the leaves of the plant. The xylem is composed of tubular cells that run throughout the stems and leaves of vascular plants.arrow_forwardMake a crossword puzzle comprising of 20 words using what you have learned from plants’ structural organization including tissue and organ systems. There should be 10 words ACROSS and 10 words DOWN and all words shall intersect at least one other word. The clues should correctly describe the word related to plant structural organization.arrow_forward
