Question

please I need short answer for each question.

Question 1: Based on the fibrous root of this seedling, how many cotyledons do you expect it to have? What is the general term for plants of this type? Soil Shoot Light Seed Root Figure 1 Question 2: A fungus grows with long, thin threads meant for absorption. What are they called? What is the structure called that they comprise? Question 3: Lilies tend to have three or six petals. Wheat plants have leaves with parallel veins. Apple trees have two cotyledons. Would you categorize lilies with wheat or apples? Explain your answer. Question 4: What feature is shared by the mycelium and mushroom? Would you know if there was a mycelium present if you didn't see the mushroom? Question 5: What is structure B? How is it like a fertilized egg of an animal? Does I or II show sexual reproduction?

Answer 1

1. Based on the fibrous roots of the seedling, one cotyledon will be present in the seedling. Plants with one cotyledon are known as monocotyledons.

2. The long, thin thread-like structures in fungus used for absorption are called as hyphae. Hyphae is comprised of septa, an internal cross-walls that divide hyphae into cells.

3. Yes, lilies can be categorised with Apple and Wheat. Lilies are monocots, as monocots have flower parts in three or multiples of three as seen in lilies. Like apple, lilies also have embryo with 2 cotyledons. Being a monocot, leaves of lilies have parallel venation.

4. Mycelium is multicellular and vegetative body for fungus that can grow into macro-size structure often called as mushroom. When compared to a plant, mycelium is like root and mushroom is like flower and hence mycelium can be distinguished from mushrooms.

5. The structure B shown in the figure is Sporangium. Sporangium is a capsule structure where reproductive spores are formed. Figure II is that of sexual reproduction.
