Class 7 Science - MAHARASHTRA
Life Processes in Plants
The chapter 'Life Processes in Plants' for Class 7 Maharashtra State Board (MSBSHSE) explores how plants survive, grow, and maintain life. Students learn about the vital transport systems in plants—xylem and phloem—which move water, minerals, and food throughout the plant body. The chapter also details the process of excretion in plants, explaining how they discard waste materials like gases, shed leaves, or store wastes in fruits and bark. Understanding these biological processes is essential for grasping how flora sustains life on Earth and forms a foundational concept for future board exam biology questions.

Transport System in Plants
Plants have specialized vascular tissues called xylem and phloem that transport water, minerals, and prepared food to all parts of the plant.
Xylem
The vascular tissue responsible for the upward transport of water and dissolved minerals from the roots to the leaves and other aerial parts.
Phloem
The vascular tissue that transports food synthesized during photosynthesis from the leaves to storage organs and other growing parts of the plant.
Excretion in Plants
The process by which plants get rid of waste products. Unlike animals, plants store wastes in specific cells, old leaves, bark, or drop them into the soil.
Root Pressure
The pressure developed in the roots due to the continuous inflow of water, which helps push water upwards into the stem.

Board Exam Info
In the Maharashtra (MSBSHSE) Class 7 Science examinations, this chapter typically carries about 4 to 6 marks. Common question types include fill in the blanks, distinguishing between xylem and phloem, short answer questions on plant excretion, and diagram-based questions illustrating transport in plants.
Frequently Asked Questions
What is the main difference between xylem and phloem?
Xylem transports water and minerals upward from the roots, whereas phloem transports food made in the leaves to all other parts of the plant.
How do plants excrete waste if they do not have a special excretory system?
Plants excrete waste by storing them in vacuoles, old leaves, bark, or fruits that eventually fall off, or by releasing gases through stomata.
Why is transport important in plants?
Transport is essential because water absorbed by roots must reach the leaves for photosynthesis, and food made in leaves must reach every cell for growth and survival.
