These stomata are from the leaf of a common horsetail. Describe how stomata and other adaptations facilitated life on land and ultimately led to the formation of the first forests.

Short Answer

Expert verified

Stomata are the openings that are found under the leaf surface. Plants are exposed to different conditions like dryness, excess moisture and were handled by developing adaptations. Bryophytes avoid excess dryness by holding metabolism while tracheophytes develop a cuticle layer to avoid water loss.

These adaptations reduce the carbon dioxide availability, which leads to the development of stoma, which allows gaseous exchange. This adaptive feature increased the chances of developing vascular tissues, xylem, and phloem to exchange nutrients. Thus, the formation of forest occurred.

Step by step solution

01

Step-1: Stomata

Stomata are pores that are minute and found under the leaves. They control the movement of carbon dioxide for photosynthesis and surplus oxygen from the plant. These minute openings allow the exit of vapors during transpiration.

02

Step-2: Adaptations of plants

Plants are living organisms that produce their food by photosynthesis and are the energy source for most of the organisms. These plants adapt themselves to the prevailing environment.

Bryophytes handle conditions like extreme dryness by holding the metabolic processes to avoid losses. The plants of tracheophytes develop cuticle, waterproof layers to avoid excess water. These adaptations lead to the evolution of stomata.

03

Step-3: Adaptations that facilitate survival

The stomata, which determine transpiration rate and perform gas exchange, led to the development of vascular tissues. The xylem and phloem involve in the exchange of nutrients that facilitate the survival of plant life. Thereby, stomata facilitate the formation of the first forest.

Giant lycophyte trees had microphylls, whereas ferns and seed plants have megaphylls. Write a short essay (100–150 words) describing how a forest of lycophyte trees may have differed from a forest of large ferns or seed plants. In your answer, consider how the type of forest may have affected interactions among small plants growing beneath the tall ones.

Make two bar graphs (for granite and andesite) comparing the mean amounts of each element weathered from rocks in the control and experimental microcosms. (Hint: For an experimental microcosm, what sum represents the total amount weathered from rocks?)

Three of the following are evidence thatcharophytes are the closest algal relatives ofplants. Select the exception.

(A) similar sperm structure

(B) the presence of chloroplasts

(C) similarities in cell wall formation during celldivision

(D) genetic similarities in chloroplasts

The feather moss Pleuroziumschreberiharbors species of symbiotic nitrogen-fixing bacteria. Scientists studying this moss in northern forests found that the percentage of the ground surface “covered” by the moss increased from about 5% in forests that burned 35 to 41 years ago to about 70% in forests that burned 170 or more years ago. From mosses growing in these forests, they also obtained the following data on nitrogen fixation:

(a) Use the data to draw a line graph, with age on the x-axis and the nitrogen fixation rate on the y-axis.

(b) Along with the nitrogen added by nitrogen fixation, about 1 kg of nitrogen per hectare per year is deposited into northern forests from the atmosphere as rain and small particles. Evaluate the extent to which Pleurozium affects nitrogen availability in northern forests of different ages.

Which of the following characteristics of plants is absent in their closest relatives, the charophyte algae?

(A) chlorophyll b

(B) cellulose in cell walls

(C) sexual reproduction

(D) alternation of multicellular generations
