(c) Lateral roots are present in a tap root.
(d) Leaves perform the function of transpiration only. 


Solution

(a) The given statement is wrong. 
Correct statement - Anther is a part of the stamen.

Stamens are the male reproductive part of a plant. The two parts of a stamen are anther and filament. The part of stamen where pollen is produced is anther.

Sepals are green leafy parts present under petals and protect the flower buds from damage.


(c) The given statement is correct.
Lateral roots are present in a tap root. Taproot is the main root and the smaller roots are called lateral roots. 


(d)The given statement is wrong. 
Correct statement - Leaves perform three main functions, i.e. photosynthesis, transpiration, and respiration.

Photosynthesis: Green leaves prepare food for plants by using water and carbon dioxide in the presence of sunlight. This is the process called photosynthesis.

Transpiration: Other than photosynthesis, leaves play a crucial role in the removal of excess of water from plants through tiny pores in them. This is the process of transpiration.

Respiration: Respiration in plants is the process used by plants to convert nutrients obtained from soil into energy which helps in the plant's cellular activities.
