Chapter 28.2, Problem 1TYK
Summary Introduction
Introduction:
Growth in plants is restricted to certain regions wherein cells divide near the tip of the plant shoot. But in animals, growth is such that cell division occurs on all parts of the body and slows down with time unlike plants wherein growth continues throughout its lifespan.

A plant stem's two main functions are to support
the leaves and to transport materials between
roots and leaves. As
a stem develops, it
possesses three types of permanent tissues:
surface tissue, ground tissue, and vascular
tissue. The surface and ground tissues support
and give structure to the plant. The vascular
tissues are the transport systems of the plant.
The vascular tissues usually exist in one of three
patterns and are known as the phloem and
xylem.
Both the xylem and phloem are made up of
several different types of cells that make up
transport tubes for needed nutrients. In general,
xylem nutrients (sap) travel from the roots to the
rest of the plant. Phloem sap is derived from
photosynthesizing leaves and from there is
carried throughout the plant.
24. What would we be able to study by
Hg einjecting a nutrient dye into the root of a
plant?
A. phloem sap transport
B. all vascular tissues
C. xylem sap transport
D. pith and cortex cells

E. total plant photosynthesis
Plant stem cells such as those found in cambium tissues are able to
-fight microbial invaders by becoming mobile and phagocytic.
-produce nutrients for other cells.
-remain undifferentiated but divide to produce cells that differentiate into new tissues.
-exist as mature cells.

- Plant B grows in unstable soil, it also needs to grow rather tall and grow quickly. This results in a tall, thin plant, grows, reproduces and dies in one year. What type of root adaptaion might it have, and what kind of life cycle would it have (use the plant terminology for life cycles)? Stolons and biennial life cycle Fiberous roots and annual life cycle O Prop roots and annual life cycle Prop roots and indeterminate growtharrow_forwardA mutation causes the vascular cambium in a plant to stop working. How does this impact cellular respiration? The stomata would remain open and release water vapor. The guard cells would remain closed and store water vapor. The leaves would not be able to release glucose for energy production. The xylem would not be able to transport water to the rest of the plant.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_forward

- Plant Physiology Define or describe and give 2 functions of the plant tissue: Meristemarrow_forwardWhat are the flaws ? Meristematic tissue is the site of mitosis and therefore growth for a plant. Apical meristem is found at the tips of roots and shoots and allows them to produce flowers. Lateral meristem is found along the length of the plant and allows it to increase in width. Intercalary meristem is found in nodes along grasses and allows them to grow from the “base”, which is why grass continues to grow after it is cut. Plants have three organs: leaves, stems, and roots. While the functions of the organs are the same between plants, the structure is different between two large groups of plants: monocots and dicots. Leaves are the site of photosynthesis. In monocots, the vascular tissue is in parallel veins like in grass. In dicots, the veins form a web or net pattern like in a maple leaf. A bulb is a modified leaf that allows the plant to store food. Stems make up the “body” of the plant and support the leaves. In monocots, vascular bundles are found randomly throughout the…arrow_forwardWhich of the following is the defining feature of true vascular tissue in plants?
