FAQs on Worksheet: Plant and Animal Tissues - Biology Class 7 ICSE

1. What are the main types of plant tissues and their functions?
Ans. The main types of plant tissues are meristematic tissues and permanent tissues. Meristematic tissues are responsible for the growth of plants and are found in areas such as root tips and stem tips. Permanent tissues, on the other hand, are divided into simple and complex tissues. Simple tissues include parenchyma (involved in storage and photosynthesis), collenchyma (provides support), and sclerenchyma (offers rigidity). Complex tissues include xylem (transports water and minerals) and phloem (transports food).
2. What are the different types of animal tissues?
Ans. Animal tissues are classified into four main types: epithelial, connective, muscular, and nervous tissues. Epithelial tissue covers body surfaces and lines cavities. Connective tissue supports and binds other tissues and organs; it includes bone, blood, and adipose tissue. Muscular tissue is responsible for movement and is categorized into skeletal, smooth, and cardiac muscles. Nervous tissue makes up the brain, spinal cord, and nerves, facilitating communication within the body.
3. How do plant and animal tissues differ in structure and function?
Ans. Plant tissues often consist of rigid cell walls made of cellulose, providing structural support and protection. In contrast, animal tissues lack cell walls, allowing for more flexibility and complex structures. Additionally, plant tissues are generally organized for photosynthesis, transport, and storage, while animal tissues are specialized for movement, protection, and signaling. This fundamental difference reflects their distinct roles in their respective organisms.
4. Why is understanding plant and animal tissues important in biology?
Ans. Understanding plant and animal tissues is crucial in biology as it helps in comprehending how organisms grow, develop, and function. It also aids in recognizing how different tissues work together to maintain homeostasis, respond to environmental changes, and perform essential life processes. This knowledge is foundational for fields such as medicine, agriculture, and environmental science, where tissue understanding can lead to advancements in health and food production.
5. What role do meristematic tissues play in plant growth?
Ans. Meristematic tissues are fundamental for plant growth as they contain undifferentiated cells capable of continuous division. These tissues are primarily located at the tips of roots and shoots, allowing for primary growth (lengthening) and increase in height. They also contribute to secondary growth (thickening) in some plants, leading to the development of woody structures. The ability of meristematic tissues to differentiate into various types of cells enables the formation of all other plant tissues.
