Summary Introduction
Introduction: There are two types of growth that occur in plants. One is primary growth that takes place in apical parts such as root and shoots. Another type of growth is secondary growth that occurs in the older parts of the plant. The two types of meristematic tissue that is responsible for the plant growth are apical meristem and lateral meristem.

In vascular plants, one difference between root and shoot systems is that
a. root systems cannot undergo secondary growth.
b. root systems undergo secondary growth, but do not form bark.
c. root systems contain pronounced zones of cell elongation, whereas shoot systems do not.
d. root systems can store food reserves, whereas stem structures do not.
Which of the following statements are true of xylem? A) It is found in all land plants.B) It assists in conducting of materials, such as water and minerals, throughout the plant.C) It can provide structural support to the plant.D) It is found in the gametophyte generation, but not in the sporophyte.E) It contains specialized cells known as tracheids and vessel elements
Given that (a) xylem is located toward the upper epidermis in leaf veins and phloem is located toward the lower epidermis and (b) the vascular tissue of a leaf is continuous with that of the stem, suggest one possible arrangement of vascular tissues in the stem that might account for the arrangement of vascular tissue in the leaf.

- Plant roots develop differently from plant shoots during primary growth. Explain: How is the formation of lateral roots different from making new branches on shoots? Why don't roots and shoots generate new primary growth the same way?arrow_forwardMatch A, B, C, D,E with the following: -zone of division -apical meristem -zone of maturation -root cap -zone of elongationarrow_forwardWhat is an adventitious root? In a monocot rhizome such as that of irises and bamboo, are adventitious roots common or rare? If a bamboo rhizome grows 100 feet underground and then sends up an aerial branch, where does that branch get its water—from the roots 100 feet away or from adventitious roots right at its basearrow_forward
- If you were given an unfamiliar vegetable, how could you tell if it was a root or a stem, based on its external features and a microscopic examination of its cross section?arrow_forwardWhat are the functions of stomata and lenticels? In what ways do these structures differ?arrow_forwardPines and other plants that grow in very cold climates have sunken stomata just like the plants of the desert, yet the annual precipitation where they grow may be very abundant. Is there any advantage to their having such a modification?arrow_forward
- Why is it that even if you put the newly germinated seed in an inverse position (roots above), the roots will find its way back to the ground?arrow_forwardWhat are apical meristems?Which type of plant growthdoes this meristem promote?arrow_forwardWhy is the secondary xylem and phloem always to either side of the vascular cambium and is the primary xylem pushed inwardly by the secondary tissues? How about the primary phloem, cortex and epidermis, are they pushed outward by the secondary tissues?arrow_forward
- Why would it be necessary for an evolutionary line to develop stomata and guard cells before it developed an extremely impervious cuticle? Why must vascular tissues precede the evolution of roots and active apical meristems?arrow_forwardAs plants grow, they tend to align theirstems and roots along the direction of the gravitational field. This tendency, which is related to differential concentrations of planthormones known as auxins, is referred to as gravitropism. As an illustration of gravitropism, experiments show that seedlings placed inpots on the rim of a rotating turntable do not grow in the verticaldirection. Do you expect their stems to tilt inward—toward the axisof rotation—or outward—away from the axis of rotation?arrow_forwardWhich 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_forward
