Chapter 44.2, Problem 1HYEW
Summary Introduction
To determine:
How trees can live so long.
Introduction:
The flowering plants generally grow throughout the life. The plant consists of two types of cells, meristematic cells, and differentiated cells. Meristematic cells are the actively dividing cells while differentiated cells are the mature cells which are specialized to perform a particular function.

The presence of the vascular tissue allows a plant to grow much larger than its gametophyte counterpart and non-vascular plants. What are two functions (not structures) of the vascular tissue that allow for this?
Another issue for these trees is fire. Giant redwood trees are very adapted to tolerate fire. The mature trees have thick bark which helps them survive most fires. Younger trees are still at risk. The seeds can remain dormant in cones for many years (estimated 20) and germinate best after the cone is exposed to fire. However, highintensity fires (hot temperatures) are risky for seeds and trees of all ages. What are two things you could do to try and mitigate (reduce) the risk of fire damage but still allow for good seed germination in forests?
Do you agree that it is the stem that
is growing? Why or why not?
Notebook Entry 1
My seed has begun to
grow. I think the thing
coming out of the split seed
is the stem. It will begin to
grow up in a few more
days. Later, the root will
begin to grow.

- While camping you notice a “Do Not Litter” sign nailed onto the trunk of a mature oak tree about 7 feet off the ground. When you return five years later, will the sign be at the same height, or will the tree’s growth have raised it higher?arrow_forwardREAD THE FOLLOWING INSTRUCTIONS: Bryophytes in which the gametophytes are "leafy" in appearance and the sporophytes grow conspicuously from the tips of the gametophyte plants. STEP 1: Examine the mass of moss plants and then select one or two individual gametophyte plants and note the leaf-like (not true leaves because they lack conducting tissue) structures which are arranged around a central, vertical "stem-like" stalk and root-like rhizoids which anchor the plant and absorb water and nutrients. STEP: The sex organs are in the tips of the plants and must be seen with the microscope. Study a slide of a vertical section through head of a mate plant and note the many antheridia. STEP 3: Examine a slide through a vertical section of a female plant. Note the many upright archegonia each on a tall stalk and each with a swollen base or venter containing an egg and an elongate neck. Note the filamentous paraphyses between the archegonia.

- Leaves of conifers are perennial. Those of bristlecone pine live for at least ____ years, and their vascular bundles produce new _____________ every year. Many conifers have needle-shaped leaves, but those of incense cedar are ____________ shaped (as shown).arrow_forwardWhy do trees grow and stop at different heights? For example an American Beech tree grows to a height of 50-70 feet but the Coastal Redwood grows to a height of 380 feet. Why is there such a big difference in growth and what makes the tree not grow forever?arrow_forwardThe center of the woody stem is called the pith. Over the years it gets very hard and becomes clogged with resin. This seals out moisture. This center wood is called heartwood. The outer, newer wood is called sapwood. The bark of the tree is very interesting. Different trees have different bark. You can sometimes tell a tree by its bark. Bark is all the tissue between the cambium and the outer surface of the stem. Bark is divided into two sections, inner and outer bark. The outer bark, which is what you see, protects the tree from disease and the environment. This outer bark is actually dead cork tissues. The inner bark is living tissues like cork cambium, cortex, and phloem. As new cork tissue develops from the cork cambium, it pushes out on the dead cork tissue of the outer bark. This causes the outer bark to crack. This forms the unique patterns on the barks of trees.

- Early botanists admired ferns but found their life cycle perplexing. In the 1700s, they learned to propagate ferns by sowing what appeared to be tiny dust like “seeds” that they collected from the undersides of fronds. Despite many attempts, the botanists could not locate the pollen source, which they assumed must stimulate these “seeds” to develop. Imagine you could write to these botanists. Compose a note that explains the fern life cycle and clears up their confusion.arrow_forward1. Of the plant groups included in Figure 1-1, which taxes have seeds? 2. Are the angiosperms more closely related to the bryophytes or the gymnosperms? 3. Explain your answer to question #2 4. Circle the node in Figure 1-1 that indicates the most recent common ancestor of gymnosperms and angiosperms. 5. List the characters that differentiate monocots and eudicots ( two groups of angiosperms) as seperate branches on the phylogenetic tree. In addition, give several examples of each.arrow_forwardToday, the tallest bryophytes reach a maximum height of 20 centimeters (8 inches) or so. So far as we know from fossils, there were no giants among their ancestors. Lignin and vascular tissue first evolved in relatives of club moss, and some extinct species stood 40 meters (130 feet) high. Among modern seed plants, Sequoia (a gymnosperm) and Eucalyptus (an angiosperm) can be more than 100 meters (330 feet) high. Explain why the evolution of vascular tissues and lignin would have allowed such a dramatic increase in plant height. How might being tall give one plant species a competitive advantage over another?arrow_forward
- Put the following 3 fictional plants in order from earliest to most recent according to their characteristics: A. The Terpad Plant: This plant reproduces using spores and has proper leaves and vascular tissue. B. The Feltris Plant: The Feltris plant lives in moist environments since it doesn't have any vascular tissue to maintain hydration throughout the plant. This plant has no roots either but has small root-like structures called rhizoids which help anchor them to the ground. Water is also required in order for fertilization. C. The Lancelot Plant: This plant can grow in either moist or dry environments, has true roots, stems and leaves and reproduces via seeds which develop within an ovary.arrow_forwardPlant 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.arrow_forwardEarly botanists admired ferns but found their life cycle perplexing.
