Questions Related to transport in organisms

Which one of the following helps in the upward movement of water and dissolved minerals from the roots to the leaves through the stem ?

botany breath and blood of life stomata and transpiration transport in organisms long distance transport of water different types of circulatory systems

  1. translocation

  2. transportation

  3. transpiration

  4. transaction

Show answer
Correct Option: C
Explanation:

The continuous evaporation of water (or transpiration) from the cells of a leaf crates a kind of suction which pulls up water through the xylem vessles. Thus, transpiration helps in the upward movement of water and dissolved minerals from the roots to the leaves through the stem.

The process in which loss of water occurs in the form of water vapour is

  1. Respiration

  2. Guttation

  3. Transpiration

  4. Exosmosis

Show answer
Correct Option: C
Explanation:
Respiration  is a process in which living organisms produces energy, with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances.
Guttation is the loss of water in the form of water droplets from hydathodes (small pores) on the leaf margin of a plant.
Transpiration is the process where plants absorb water through the roots and then give off water vapor through pores in their leaves.
The passage of material through a semi-permeable membrane from a region of higher to a region of lower concentration, especially the passage of water through a cell membrane into the surrounding medium, is called exosmosis. 
Thus, the correct answer is option (C). 

A leafy twig of mesophytic plant dipped in water would demonstrate

  1. Photosynthesis

  2. Transpiration

  3. Respiration

  4. Gutttation

Show answer
Correct Option: B
Explanation:
Mesophytic plants are the plants which grow in the areas/lands which is not too dry not too wet.
When this type of plant is dipped in water (making hydrophytic) then it will demonstrate transpiration More will be the amount of water and more will be the transpiration rate.
Biochemical processes like photosynthesis, respiration and guttation do not depend upon the nature of land but transpiration depends upon the amount of water present in the soil.
So, the correct answer is 'Transpiration'.

The loss of water from the aerial parts of the plant is known as

botany breath and blood of life different types of circulatory systems stomata and transpiration transport in organisms

  1. Photosynthesis

  2. Transpiration

  3. Reproduction

  4. Respiration

Show answer
Correct Option: B
Explanation:

Photosynthesis is the process of synthesis of food from inorganic compounds like carbon dioxide and water and sunlight.

Transpiration is the process of release of water vapour from aerial parts, such as leaves, stems and flowers.
Reproduction is the process of producing an offspring for continuation of species.
Respiration is the process of releasing energy by breaking down organic compounds like sugars.
So, the correct answer is 'Transpiration'.

Which of the following is not one of the four most common elements found in living organisms?

biology breath and blood of life different types of circulatory systems stomata and transpiration transport in organisms

  1. Hydrogen

  2. Carbon

  3. Sulphur

  4. Nitrogen

Show answer
Correct Option: C
Explanation:
The cells of living things are made mainly of four elements: carbon, hydrogen, oxygen and nitrogen. Phosphorus and calcium are next in abundance after these 4 elements. Almost 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus.
So, the correct option is 'Sulphur'.

System of vessels and tubes in animals is called as

biology breath and blood of life different types of circulatory systems stomata and transpiration transport in organisms

  1. Digestive system

  2. Circulatory system

  3. Respiratory system

  4. Reproductive system

Show answer
Correct Option: B
Explanation:

Human circulatory system, also called the blood vascular system consists of a muscular chambered heart, a network of closed branching blood vessels and blood, the fluid which is circulated. It is essentially a network of tubes that supplies to all living cells essential nutrients, O$ _2$ and other essential substances. Also, the waste or harmful substances produced are removed continuously for the healthy functioning of tissues.

Mark the incorrect statement

biology breath and blood of life different types of circulatory systems stomata and transpiration transport in organisms

  1. Every organ in our body needs the involvement of circulating fluids.

  2. The digestive system absorb & digest nutrients.

  3. The respiratory system removes all extra water of the body.

  4. None of these

Show answer
Correct Option: C
Explanation:

Every organ in our body needs the involvement of circulating fluid. Ex - The digestive system digests & absorb nutrients which are needed to be transported to every cell in the body.

Only the multi cellular organisms require transporting mechanisms.

biology breath and blood of life different types of circulatory systems stomata and transpiration transport in organisms

  1. True

  2. False

Show answer
Correct Option: B
Explanation:

Unicellular organisms also require transporting mechanism in order to transport nutrients, enzymes, waste products etc. The transport mechanism in unicellular organisms is simpler than multicellular organisms. Unicellular organisms can transport substances in and out of the body by diffusion and osmosis.

A transport system is needed to transport
(i) Nutrients, oxygen and hormones from the place, they are absorbed or received to the cells.
(ii) Waste products from the place they are formed to the place from where they are eliminated outside.
(iii) Heart beat, chromosome.

biology breath and blood of life different types of circulatory systems stomata and transpiration transport in organisms

  1. (i) and (ii) correct

  2. (i) and (iii) correct

  3. (ii) and (iii) correct

  4. (i) , (ii) and (iii) correct

Show answer
Correct Option: A
Explanation:

The human transport system is a system of tubes with a pump and valves to ensure one-way blood flow. We need a transport system to deliver oxygen, nutrients, hormones and other substances to all our body cells and take away waste products from them. 

Heart of cockroach is a

biology breath and blood of life different types of circulatory systems stomata and transpiration transport in organisms

  1. Membranus

  2. Muscular and tube like

  3. Absent

  4. Filled with blood having RBC

Show answer
Correct Option: B
Explanation:

A) The heart is not membranous.

B) The heart is an elongated muscular tube lying along the mid-dorsal line of the thorax and abdomen.
C) A muscular heart with thirteen chambers is present.

D) The blood of cockroaches consists of clear colourless plasma and cells called haemocytes. RBCs are absent. The blood is devoid of any pigments.
So the correct answer is 'Muscular and tube like'.
