Questions and Answers

1.

A seed with two seed leaves is called a
- A.
  
  Damaged seed
- B.
  
  Monocot
- C.
  
  Soaked seed
- D.
  
  Dicot seed
Correct Answer
D. Dicot seed

Explanation
A seed with two seed leaves is called a dicot seed. This is because dicot seeds are characterized by having two cotyledons or seed leaves, which are the first leaves to emerge from the seed upon germination. Dicot seeds are part of the dicotyledonous plants, which include a wide range of flowering plants such as roses, sunflowers, and oak trees. The presence of two seed leaves is a distinguishing feature of dicot seeds, setting them apart from monocot seeds, which have only one seed leaf.

Right soil, warmth, enough air and water are necessary conditions for the growth of
- A.
  
  Children
- B.
  
  Birds
- C.
  
  Seeds
- D.
  
  Books
Correct Answer
C. Seeds

Explanation
Seeds require the right soil, warmth, enough air, and water in order to grow. These conditions provide the necessary nutrients and environment for the seed to germinate and develop into a plant. Without these conditions, the seed may not be able to sprout or may not grow properly. Therefore, seeds depend on these specific conditions for their growth.

New plants can grow from the leaves of
- A.
  
  Ginger
- B.
  
  Bryophyllum
- C.
  
  Onion
- D.
  
  Sweet potato
Correct Answer
B. BryopHyllum

Explanation
Bryophyllum is a type of plant that can reproduce vegetatively, meaning that new plants can grow from its leaves. This process is known as leaf propagation or leaf cloning. When a leaf from a Bryophyllum plant is detached and placed in a suitable environment, it can develop roots and eventually grow into a new plant. This ability to propagate from leaves is a unique characteristic of Bryophyllum plants. Ginger, onion, and sweet potato do not have this ability, so they cannot grow from their leaves.

Which feature helps a coconut fruit to float in water?
- A.
  
  A fibrous outer covering
- B.
  
  A spongy part
- C.
  
  Presence of hook
- D.
  
  Presence of spine
Correct Answer
A. A fibrous outer covering

Explanation
A fibrous outer covering helps a coconut fruit to float in water because the fibers create air pockets that increase buoyancy. This allows the coconut to stay afloat and be carried by water currents. The fibrous outer covering also provides protection to the inner seed, allowing it to survive harsh conditions while floating in water.

Plants that need clayey soil to grow well are
- A.
  
  Wheat and gram
- B.
  
  Rice and jute
- C.
  
  Jowar and bajra
- D.
  
  Tea and coffee
Correct Answer
B. Rice and jute

Explanation
Rice and jute are plants that require clayey soil to grow well. Clayey soil has a high water-holding capacity and good nutrient retention, which is beneficial for these crops. Rice is a staple food crop that requires a lot of water, and clayey soil helps to retain moisture. Jute, on the other hand, is a fiber crop that needs a well-drained soil with good moisture retention, which clayey soil provides. Therefore, rice and jute are the correct options for plants that thrive in clayey soil.

Insecticides and pesticides protect crops from being destroyed by
- A.
  
  Drought
- B.
  
  Excessive rain
- C.
  
  Pests
- D.
  
  Elelphants
Correct Answer
C. Pests

Explanation
Insecticides and pesticides are used to protect crops from pests, which are organisms that can cause damage to crops. These chemicals are specifically designed to target and kill pests, such as insects, weeds, and fungi, that can harm or destroy crops. By eliminating or reducing the population of pests, insecticides and pesticides help to ensure the health and productivity of crops, ultimately protecting them from being destroyed.

Maize has ................................ seed leaf / leaves.
- A.
  
  Monocot
- B.
  
  Dicot
- C.
  
  Tricot
- D.
  
  Different
Correct Answer
A. Monocot

Explanation
Maize has monocot seed leaf/leaves. This means that the seed of maize produces only one embryonic leaf or cotyledon upon germination. Monocots, such as maize, typically have parallel veins in their leaves and flower parts in multiples of three. This is in contrast to dicots, which have two embryonic leaves or cotyledons, netted veins in their leaves, and flower parts in multiples of four or five. Tricot and different are not relevant terms in this context.

Any part of a potato that has ........................... on it can grow into a new plant.
- A.
  
  Bud
- B.
  
  Flower
- C.
  
  Shoot
- D.
  
  Root
Correct Answer
A. Bud

Explanation
Any part of a potato that has a bud on it can grow into a new plant. Buds are small, undeveloped shoots that contain the potential to grow into a new plant. When a potato has a bud, it means that it has the ability to sprout and produce new growth. This is why a potato with a bud can be used to propagate or grow a new potato plant.

Plants help to reduce soil .............................
- A.
  
  Production
- B.
  
  Fertility
- C.
  
  Erosion
- D.
  
  Decomposition
Correct Answer
C. Erosion

Explanation
Plants help to reduce soil erosion. The roots of plants hold the soil in place, preventing it from being washed away by water or blown away by wind. This helps to maintain the integrity of the soil and prevent erosion, which can lead to loss of topsoil and degradation of land. Additionally, plants provide ground cover, which helps to absorb rainfall and slow down the flow of water, further reducing erosion.

- A.
  
  Pea
- B.
  
  Potato
- C.
  
  Groundnut
- D.
  
  Raddish
Correct Answer
C. Groundnut

Explanation
Onions and groundnuts both require well-drained, sandy soil. This type of soil allows for proper drainage, preventing waterlogging and ensuring that the roots of these plants do not rot. Sandy soil also provides good aeration and allows for easy root penetration, which is beneficial for the growth and development of both onions and groundnuts.
