An organ is a self-contained group of tissues that performs a specific function in the body. The heart, liver, and stomach are examples of organs in humans. Organs are found in most animals and plants. …
Q. Which plant tissue has the most important function?
Xylem and phloem are the two most important complex tissues in a plant, as their primary functions include the transport of water, ions, and soluble food substances throughout the plant.

Q. What are the major plant tissues?
They differentiate into three main tissue types: dermal, vascular, and ground tissue. Each plant organ (roots, stems, leaves) contains all three tissue types: Dermal tissue covers and protects the plant, and controls gas exchange and water absorption (in roots).
Q. Which tissue type prevents the loss of water?
Dermal Tissue Epidermal cells secrete a waxy substance called cuticle , which coats, waterproofs, and protects the above-ground parts of plants. Cuticle helps prevent water loss, abrasions, infections, and damage from toxins. This tissue includes several types of specialized cells.
Q. Why do plants have different types of cells and tissues?
Answer: Plants need different types of cells and tissues to perform their day to day activities such as metabolism, food preparation and transport of raw materials and prepared food in a ‘more efficient way’.
Q. What is the main function of vascular tissues in plants?
The vascular tissues of plants, which are composed of specialized conducting tissues, xylem and phloem, form continuous systems through the plant body and provide transport pathways for water, nutrients, and signaling molecules and support a plant body against mechanical stresses.
Q. What is known as suicidal bags of cell?
Lysosomes are single membrane organelles found in eukaryotic cells. Back in 1959, Christian de Duve gave them their now famous nickname, ‘suicidal bag’, in an attempt to underline their degradative properties.
Q. What are suicidal bags Class 9?
Answer: The lysosomes contain hydrolytic enzymes which are capable of breaking down organic matter in case of any disturbance in cellular metabolism. For example, when a cell gets damaged, then lysosomes burst and enzymes digest their own cell. Hence, the lysosomes are known as ‘suicide bags’ of cell.
Q. Which cell organelle is called kitchen of plant?
Plastids
Q. Who is the kitchen of the plant?
chloroplast
Q. What controls DNA and cell activities?
Known as the cell’s “command center,” the nucleus is a large organelle that stores the cell’s DNA (deoxyribonucleic acid). The nucleus controls all of the cell’s activities, such as growth and metabolism, using the DNA’s genetic information.
