Multiple choice biology multicellular structure: tissue defense mechanism in plants epidermal tissue system kinds of plant tissue permanent tissues and their types

Which would do maximum harm to a tree?

  1. Loss of half of its leaves

  2. Loss of half of its branches

  3. Loss of all of its leaves

  4. Loss of all its bark
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
The loss of half of branches does not harm the tree much, as half of the branches are present to carry out photosynthesis and transpiration. This condition we can see in real day to day life also that if the half of the branches are cut down then also tree can be alive. 
Shedding of all leaves is carried out by the plant itself but it does not harm the tree. Soon after shedding, the new leaves can be observed on the tree. 
The bark is the outermost layer of the stems of the woody plants. All the tissues outside the vascular cambium are called as bark. It protects the tree from wear and tear, bacterial infection and water loss. If all of the bark of the tree is removed then water loss will dry out the tree and tree will also become vulnerable to infections. 
So, the correct answer is 'Loss of all its bark'

Scaly bark occurs in

  1. Eucalyptus

  2. Betula

  3. Psidium

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The bark is composed of periderm and stem's secondary phloem, the cork cambium, phelloderm and cork cells together make up the periderm. Formation of new periderm layer renders the previous layer dead due to stoppage of water and nutrient supply and differentiates the bark into two regions, namely outer and inner bark. The cork, secondary cortex and phloem present just outside the innermost phellogen constitute outer bark while rest of the tissues present in the outer bark make inner bark. Formation of subsequent periderm layers as overlapping scales gives scaly bark as is present in Psidium. When the bark is peeled off as large sheets, it is termed as intermediate bark as is found in Eucalyptus and Betula.
Thus, the correct answer is option C.

Multiple choice physics universe and space heliocentric model introduction to gravitation introduction to gravity

When a fruit falls from a tree,

  1. only the earth attracts the fruit

  2. both the earth and the fruit attract each other

  3. only the fruit attracts the earth

  4. they repel each other
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

According to the law of physics, the earth attracts the apple and the apple attracts the earth with the same intensity of gravity ( according to 3rd law of dynamics). However the displacement of the two bodies is inversely to their respective masses. The earth attracts the apple i.e it falls on an apple in a billionth of a billionth of a millimeter which is impossible to see.

Thus when a fruit falls from a tree both the earth and the fruit attract each other.

All other trees are common trees and can be used to make the handle of a spade.
The correct answer is 'sheesham'.

A plant growing on a forest floor

  1. Has shallow roots

  2. Requires low light

  3. Has a deep tap root

  4. Requires strong light

  5. Requires moist soil
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Typical plants that are found on the forest floor include a variety of ferns, mangrove trees, and vines. The canopy of trees spread their leaves to attract as much sunlight. Though the forest floor is the principal sites of decomposition, there is a stiff competition for sunlight and nutrients. The plants that occupy the forest floor are ones that require low light as they are adapted to grow under conditions of low light availability and have large dark  green leaves to absorb as much sunlight.
