Forestry and Plant Sciences Questions

Multiple choice botany know the plant world closely nutrition and its types types of nutrition in plants different modes of nutrition in plants

Santalum album$/$ Sandal-wood Tree is?

  1. Partial root parasite

  2. Partial stem parasite

  3. Total stem parasite

  4. Total root parasite
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Santalum album is a partial root parasite, because it can photosynthesize its own food, but taps the roots of other species for water and inorganic nutrients.
Thus, the correct option is 'Partial root parasite'.

Plants that grow over the branches of trees without contact with soil are

  1. Epiphytes

  2. Symbionts

  3. Saprophytes

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

Epiphytes are symbiotic plants that grow on the surface of a plant and derives its moisture and nutrients from the air, rain or from debris accumulating around it. They usually grow over the branches of trees so that they can attain sunlight as they are short.

So, the correct option is 'Epiphytes'.

Multiple choice civics the nature of the indian economy part 1 three phases of indian agriculture cash crops of india agricultural nature of indian economy plantation of crops

The practice of slash-and-burn method to clear a part of the forest and practicing agriculture in it is called?

  1. Plantation agriculture

  2. Mixed agriculture

  3. Shifting agriculture

  4. Sedentary agriculture
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • 0Slash and burn farming is a form of shifting agriculture where the natural vegetation is cut down and burned as a method of clearing the land for cultivation, and then, when the plot becomes infertile, the farmer moves to a new fresh plot and does the same again.
  • This process is repeated over and over.
Multiple choice zoology living and non living characteristics of life attributes of living organisms signs of life biology : an introduction living world and classification

Which of the following things grow? 

  1. Road

  2. Pen

  3. Water

  4. Tree
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The living organisms are composed of cells. The cells divide and the body of the organisms show growth due to the increase in the number of cells. The trees are the living organisms and show the process of growth. Road, pen and water are non-living organisms which do not show the process of growth. 

Thus, the correct answer is option D.

A plant expected to have an age of $1500$ years is?

  1. Eucalyptus

  2. Sequoia

  3. Mangifera indica

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

Sequoia has an average age of 2000 years because of favourable climatic conditions such as tannin in the bark, which makes it resistant to insects like termites. The thickness of the bark also helps protect the inner core of the tree from fire.

So, the correct option is 'Sequoia'.

The resinous substance, shellac is obtained from

  1. An insect

  2. The bark of a tree

  3. Crude oil

  4. Distillation of wood
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Shellac is a resin secreted by the female lac bug, on trees in the forests of India and Thailand. It is processed and sold as dry flakes (pictured) and dissolved in alcohol to make liquid shellac, which is used as a brush-on colorant, food glaze, and wood finish.

So, the correct answer is 'An insect'.
Multiple choice botany the life cycle of plants parthenocarpic fruits parthenogenesis asexual reproduction

Choose the correct answers from the alternatives given.
Vessels are not found in

  1. Sal wood

  2. Chir wood

  3. Teak wood

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

The presence of vessels is a characteristic feature of angiosperms. Gymnosperms and pteridophyte lack vessels though other xylary elements are present for conduction of water and minerals. Primitive angiosperm families like Tetracentraceae, Trochodendraceae and Winteraceae do not have vessels. Except for Chir wood, others are examples of angiosperms that possess vessels.

Hence, the correct answer is 'Chir wood'.

Multiple choice biology protectors of biosphere structure of chloroplast plastids photosynthetic pigments

If a tree flowers thrice in a year, in the months of October, January and July in northern India the plant is

  1. Photo and thermo-sensitive.

  2. Photo and thermo-insensitive.

  3. Photosensitive but thermo-insensitive.

  4. Thermo-sensitive but photo-insensitive.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Plants are able to detect and respond to light, gravity, changes in temperature and chemicals. Plants respond to the changing seasons to initiate their development and flowering. The photoperiodic stimulus is found to be responsible for flowering, light quality, vernalization, autonomous and GA pathways are also responsible for regulating the flowering time in plants. While vernalization and photoperiodic pathways are environmental dependents, the autonomous pathway promotes flowering in all conditions. Hence for a tree that flowers thrice a year, the plant has to be both photo and thermo-insensitive.

Multiple choice zoology ecosystems decomposition in ecosystem ecosystem productivity and decomposition producers, consumers and decomposers

Slow rate of decomposition of fallen logs in nature is due to

  1. Anaerobic environment around them

  2. Low cellulose contents

  3. Low moisture content

  4. Poor nitrogen content
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The slow rate of decomposition of fallen logs in nature is due to their low moisture content The cellulose is in high amount in fallen logs. 

Decomposers break down dead plants and animals. They also break down the waste (poop) of other organisms. Decomposers are very important for any ecosystem. Low moisture content will lead to a decrease in the number of decomposers because decomposers require an optimum moisture for their proper growth and functioning.
So the answer is 'Low moisture content'. 

Multiple choice zoology ecosystems decomposition in ecosystem ecosystem productivity and decomposition producers, consumers and decomposers

The slow rate of decomposition of fallen logs is due to

  1. poor nitrogen content

  2. anaerobic environment

  3. low cellulose contents

  4. low moisture contents
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Low or reduced moisture alters and reduces the decomposition process. A slow rate of composition of fallen logs is likely due to low moisture contents.

So, the correct answer is option D, low moisture contents.
