Explain how the reproduction cycle for mammals and animals are different and also explain the alternation of generations in Plants. Describe the cell cycle. Explain the difference between the 2 types of M cycles in the cell cycle. Explain the alternation of generations during a plant's life cyc...
The relationship between plant productivity and species richness is one of the most debated and important issues in ecology. Ecologists have found numerous forms of this relationship and its underlying processes. However, theories and proposed drivers ha
How can asexual reproduction in plants produce genetically identical offspring when meiosis occurs? Describe mitosis and meiosis and how they differ. How does meiosis play a role in heredity? Explain the difference between the outcome of nondisjunction during meiosis I versus meiosis II. How does the...
4. Storage and Reproduction: - Some plants have modified stems such as tubers (e.g., potatoes) and rhizomes (e.g., ginger). These structures store food and help in vegetative propagation, allowing the plant to survive unfavorable conditions. 5. Leaf Modifications: - In xerophytic plants, ...
10. Studies onSilene latifoliahave noted that males exhibited higher reproductive costs because they invest more biomass in reproduction11. Ultimately, female-biased sex ratios are rarer than male-biased sex ratios in dioecious species, and the dominant status of the male-biased sex ratio is the ...

Ever since existence of sexuality in plants was accepted in around 1700, questions centred about the role and maintenance of sexual reproduction in general, leading to a number of hypotheses like the Vicar of Bray, the Ratchet or the Hitch-hiker theory. Bell (The masterpiece of nature. The ...
Most bryophyte populations exhibit female-skewed expressed adult sex ratios, generally inferred from counts of sexually mature plants. For the rarely sexually reproducing perennial dioicous moss Drepanocladus lycopodioides, we showed that a female bias also exists in the genetic adult sex ratio, ...
Is xylem or phloem larger in a plant? Providing examples, explain how sexual reproduction in plants has evolved to become less dependent on water. Explain how do marine animals survive in water without air contact. Mosses typically do not grow to be very tall at all...
