Which of the following is an angiosperm?

  1. Sugarcane

  2. Pine

  3. Cedar

  4. Fir


Correct Option: A
Explanation:

Sugar cane is a perennial tropical grass with tall stout jointed stems from which sugar is extracted. Sugarcane is a flowering plant belonging to the monocotyledonous group of angiosperms. Angiosperms are also called as seed plants or flowering plants.

Thus the correct option is A. 

Cycas and Pinus belongs to 

  1. Thallophyta

  2. Bryophyta

  3. Pteridophyta

  4. None of the above


Correct Option: D
Explanation:
Cycas and Pinus are two genera belonging to gymnosperms.Cycas is a dioecious tree while Pinus is a monoecious tree.
So, the correct answer is  'None of above'

Chara belongs to 

  1. Gymnosperm

  2. Thallophyta

  3. Bryophyta

  4. Pteridophyta


Correct Option: B
Explanation:

Answer is B. Thallophyta

Biological classification of Chara :- 

Division :- Thallophyta 

Sub division :- Algae 

Class :- Charophyceae

Order :- Charales 

Family :- Characeae 

Genus :- Chara 

==>>Occurrence of Chara :-

This is a fresh water form, which generally grows submerged in water and remain attached to the bottom with the help of rhizoids. Some species like chara battica may be found in Saline water.

Identify the bryophyte(s) from the following.

  1. Riccia

  2. Moss

  3. Cycas

  4. Both A and B


Correct Option: D
Explanation:
Answer is D-A and B both
Riccia is a genus of liverworts in the order Marchantiales. These plants are small . The sporophyte of Riccia is the simplest amongst bryophytes.
mosses are non-vascular plants in the land plant division Bryophyta.

Mention whether the following statement is true or false:
Animals show movement while the plants do not

  1. True

  2. False


Correct Option: A
Explanation:

Plants are sedentary organisms, where as animals show movement due to the presence of locomotory organs.

So, the statement is ‘True’.

Which of the following is the characteristics of plants?

  1. Multicellular with specialised tissues and organs

  2. Photosynthetic and contain chlorophylls a and b

  3. Protect developing embryo from desiccation

  4. All of the above


Correct Option: D
Explanation:

Plants are green nonmotile stationery living beings that grow in the soil. These are multicellular and has specialized tissues and organ to perform the various function of the plant body. They helps to prepare their food by photosynthesis with the help of pigments chlorophyll a and chlorophyll b.

Desiccation is the drying of the cell and the specialized tissue of plants protect the developing embryo from desiccation.
So, the correct option is 'all of the above'.

Which of the following statements are correct?

  1. Fungi possess tissues

  2. Animals possess tissues

  3. Plantae possess tissues

  4. All of the above


Correct Option: D
Explanation:

Organisms of kingdom fungi have multicellular or loose tissue. In organisms of kingdom Plantae, the body organisation is tissue or organ grade whereas body organisation in kingdom Animalia is tissue or organ or organ system. In unicellular organisms, all functions like digestion, respiration and reproduction are performed by a single cell. In the complex body of multicellular animals, the same basic functions are carried out by different groups of cells in a well-organised manner. The body of a simple organism like Hydra is made of different types of cells and the number of cells in each type can be in thousands. The human body is composed of billions of cells to perform various functions. In multicellular organisms of fungi, plant and animal kingdoms, a group of similar cells perform a specific function. Such an organisation is called tissue.
