Question

Give reasons for the following statements : 1. Cactus flowers bloom at night. 2. Coconut palms have thick shiny leaves. 3. Desert plants have spines on their stem. 4. Trees in the rainforests have smooth stems. 5. Aquatic plants have a hollow stem.​

Answer 1

Explanation:

1. Cactus plants' flowers are pollinated at night is a significant element. Pollination is aided by night-flying insects and moths, which helps to enhance reproduction. Thus, Cactus flowers bloom at night.
2. Palm "trees," like other succulent plants, secrete a sour sap known as aloe. This is a natural antifreeze that keeps the plant cold and protects it from the sun. The sap also enables the plant to thrive in a saltwater environment, such as on a desert island without access to freshwater.
4. Coconut milk is high in minerals and carbohydrates, which the new plant will require throughout its incubation phase. It will be almost eternal once it has taken hold, withstanding hurricane-force gusts and temperatures of up to 50 degrees Celsius. Other plants lose moisture through their pores which they have on their leaves and stem. So, these desert plants need to avoid those pores to lock the minimum levels of moisture they have. Hence, these leaves don't have pores and the leaves become hard with dry spines or thorns.
5. Tree trunks - these are tall and thin to allow trees to reach the sunlight. The bark on these trees is smooth to allow water to flow down to the roots easily.
6. The root shoots The roots plants are fixed at the bottom of the pond. They have a long hollow stem that is light and flexible. This type of stem helps them to remain afloat and move with the water so that they do not get damaged.
