LIFE PROCESSES
1) What are different types of life processes?
Life on the earth exists based on certain functions and processes. There are some processes for obtaining nutrition, some help in procreating offspring. The processes which maintain body functions and are necessary for survival are called life processes. The important life processes are nutrition, transportation, movement, reproduction, respiration, and excretion.
2) Define autotrophic nutrition?
The literal meaning of this term is self nutrition.Autotrophic Nutrition is a process where the organism prepare their own food from the simple inorganic materials like carbon dioxide, water and mineral salts in the presence of sunlight. All the green plants possess autotrophic mode of nutrition
3) Define heterotrophic nutrition?.
Every non-autotrophic organism which depends on others for their food is called heterotrophs. Heterotrophs include every animal and non-photosynthetic plant which are unable to prepare organic molecules on their own.
4) What are the functions of stomata?
The tiny pores or openings present under the leaves of the plants is called stomata.
Two functions of stomata:
(i) It helps in breathing of the plants.
(ii) It helps in exchange of gases which takes place inside the plant cells.
