'Xylem' and 'phloem' vessels are found in

  • leaves only
  • stem only
  • roots only
  • whole plant

The transportation of food and mineral salts from leaves to all other parts of the plant by phloem is known as

  • translocation
  • transpiration
  • respiration
  • photosynthesis

The rate of transpiration depends on

  • condition of a plant
  • surroundings
  • plant's condition and surrounding
  • temperature

Some amount of mineral salts enter the roots by the process of

  • diffusion
  • osmosis
  • active transport
  • respiration

More force is required to pull water and minerals up to the leaves of

  • small stems of growing plants
  • tree trunks
  • herbs
  • ferns

The cross walls of phloem vessels are known as

  • cross tissues
  • cross plates
  • sieve walls
  • sieve plates

The vessel that carries mineral salts from the roots to leaves is

  • xylem
  • phloem
  • branch
  • stem

The force acting on water and minerals from bottom is known as

  • root stream
  • root pressure
  • root push
  • root pull

If an ink drop is dropped in water and it spreads equally in water. It is called

  • diffusion
  • osmosis
  • active transport
  • respiration

In plants roots take up water by the process of

  • diffusion
  • osmosis
  • active transport
  • respiration

As wind blows, it takes water vapors away from plant and decreases the humidity. This process

  • increases the rate of transpiration
  • decreases the rate of transpiration
  • keeps the rate of transpiration same
  • may increase or decrease the rate of transpiration

Root cells contain a large amount of

  • food only
  • food and minerals
  • minerals and sugar
  • food and sugar

Most of the oxygen from soil is dissolved in

  • minerals
  • water
  • mineral salts
  • roots hair

As the light intensity increases the rate of transpiration is also

  • increased
  • decreased
  • remained same
  • remained unchanged

The food is carried away from leaves to the other parts of plant by

  • dead cells of xylem
  • sieve tubes of phloem
  • companion cells of phloem
  • root pressure in xylem

The process in which water and mineral salts are moved from the roots to the leaves by xylem is generally known as

  • transpiration
  • translocation
  • respiration
  • photosynthesis

The process in which the particles move from lower concentration to higher concentration is known as

  • diffusion
  • osmosis
  • active transport
  • translocation

The process that requires energy to move particles from one region to the other is

  • osmosis
  • active transport
  • transpiration
  • translocation

'Phloem' is a vessel in the plants which carries

  • food and minerals to leaves from roots
  • food and minerals to roots from leaves
  • prepared food to other parts from roots
  • prepared food to other parts from leaves

Water evaporates from tiny pores on the lower part of leaf. These pores are known as

  • cuticles
  • lenticels
  • epidermis
  • stomata
