HIGHER ORDER THINKING SKILLS (HOTs)

1. What is the role of wind, water and insects in sexual reproduction of plants

1.  

      a.Sugarcane  ( stem in sugarcane reproduces) 

2. 

        1.  False - Ginger reproduces through underground modified stems such as rhizome

2.  False - Vegetative propagation takes place in banana through underground modified stems such as rhizome

3.  True - Budding is common in yeast and hydra .

3.  

        Asparagus. It can grow from seeds and crowns and others can grow by vegetative propagation.

4.

        1.  Stamen is the male sex organ and the pistil is the female sex organ. Flowers that contain both stamen and pistil are called bisexual flowers and plants that bear them are called bisexual plants and the flowers bear either the stamen or the pistil are called unisexual flowers and plants that bear them are called unisexual plants.

         2. Stamen is the male reproductive organ of the flower. It is the collection of stamens. It is also known as androecium.  Pistil is the  female reproductive organ of the flower. It is the collection of carpels. It is also known as gynoecium.

         3. The small piece of any plant organ used for propagation is called cutting. Example: Rose, sugarcane etc..Grafting is a method in which two plants are joined in such a way that grow as one plant. Example: Lemon, sweet orange etc.

5.

1. Bougainvillea - Asexual reproduction through stem cutting.
2. Potato - Asexual reproduction through vegetative part of the plant – stem.
3. Croton - Asexual reproduction through stem cutting.

6. 

      Flower:

• Platform for sexual reproductive system
• Attracts pollinators and facilitate pollination

Coloured Flowers:  

• Attracts biotic agents like fly and insects for pollination
• Helps to identify the species

Sepals: 

•  Protect flower in its initial stages when it is in the form of bud. Protect ovary and support petal.

Anther:

•  It is the upper bilobed part and each lobe contains two pollen sacs within which numerous pollen grains are produced. 
•  It helps for fertilization.

Ovary: 

• It contains ovules and each ovule has an egg cell- the female gamete. It helps for fertilization.

7. 

• Modified swollen underground stem of ginger -Protect the plants from animals.
• The process of production of individuals of the same kind –Reproduction

8. 

•   Wind, water and insects are the common agents responsible for successful pollination in sexual reproduction of plants.
