Forestry and Plant Sciences Questions

Multiple choice

Conifers have

  1. Needle like leaves

  2. Woody cones that contain their seeds

  3. Milk for snacks

  4. conical shape

A,B,D Correct answer
Multiple choice

Which of these is an evergreen tree?

  1. Mahogany

  2. Semul

  3. Sandalwood

  4. Deodar
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Mahogany is a classic example of a tropical evergreen tree found in regions with heavy rainfall. In contrast, Semul and Sandalwood are deciduous trees, and Deodar is a coniferous mountain tree.

Multiple choice

Coniferous trees are conical in shape.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Coniferous trees have a distinct conical shape with sloping branches, which helps them survive in snowy mountain regions by allowing snow to easily slide off without breaking the branches.

Multiple choice

Evergreen forests shed there leaves at the same time of the year.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Evergreen forests do not shed all of their leaves at the same time of the year, which is why they retain their green appearance year-round. In contrast, deciduous forests shed all their leaves during a specific dry or cold season.

Multiple choice

What type of tree is able to remain green during the winter time?

  1. oak trees

  2. deciduous trees

  3. conifers

  4. magnolia trees
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Conifers (such as pines, firs, and spruces) are evergreen trees that retain their needles and remain green throughout the winter. Deciduous trees, like most oaks, shed their leaves in autumn.

Multiple choice

which of these is not a sustainable use of rain forests? 

  1. Planting trees

  2. Chopping down trees

  3. Teaching people how to look after the rainforest

  4. Only chopping some trees
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Chopping down trees (clear-cutting or deforestation) destroys the ecosystem and is not sustainable. Sustainable practices, like planting trees or selective logging (only chopping some trees), allow the forest to recover and persist for future generations.

Multiple choice

Why have certain trees adapted to have Buttress Roots?

  1. To help animals to climb them

  2. To help them become more stable in thin soil

  3. To make them look funny

  4. To provide a place for animals to hide behind
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Rainforest soils are often very thin and nutrient-poor, meaning tree roots do not grow very deep. Buttress roots are large, wide roots that grow above ground to provide structural stability and prevent tall trees from falling over.

Multiple choice

Which of the following is a conifer?

  1. a pine tree

  2. an apple tree

  3. an oak tree

  4. bamboo
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Conifers are gymnosperms that reproduce using cones and typically have needle-like leaves, such as pine trees. Oak and apple trees are flowering plants (angiosperms), and bamboo is a type of grass.

Multiple choice botany pictorial feature of plant kingdom classification of bryophytes types of bryophytes bryophyta

Sex organs are embedded in the thallus in

  1. Moss

  2. Riccia

  3. Azolla

  4. Fern
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In the liverwort Riccia, the sex organs (antheridia and archegonia) develop on the dorsal surface of the thallus and become deeply embedded within cavities of the photosynthetic tissue as the thallus grows. In mosses and ferns, the sex organs are typically superficial or borne on specialized structures rather than being embedded deep within the vegetative thallus.

The moss which forms dense extensive mats on the soil prevents __________________.

  1. uprooting of trees

  2. soil erosion

  3. falling of leaves

  4. evaporation of water from the soil
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Mosses form a protective covering over the crumbling soil of cliffs and prevent the rushing rainwater from cutting deeply into the soil. These grow in dense mats so firmly intertwined around the soil particles that there can be little erosion, even on a steep hillside.

So the correct option is B.

Multiple choice

The process of planting trees in a barren land to create a Forest is ____

  1. Deforestation

Multiple choice

People describe Alaska as having “drunken trees” because:

  1. Many Alaskan trees grow in bogs soaking in fermented juices

  2. Trees tip as nitrates in the soil convert to "laughing gas"

  3. Trees tip from buckling of the ground due to permafrost thaw

  4. Arctic hare have gnawed away tree roots for winter nutrition
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Drunken trees are a common sight in areas with permafrost; as the ground thaws and becomes unstable, the trees tilt in various directions.

Multiple choice

The stem of trees bind the soil together

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

It is the roots of trees and plants that bind the soil together, preventing erosion. The stem is the main structural axis of the plant above ground.
