Worked Reasoning

Make each reasoning step visible: identify the knowns, choose the governing idea, apply it and check the result.

This extension applies that lens specifically to Plant and Animal Tissues.

A tissue is a group of similar cells that work together to do a particular job. Cells organise into tissues, tissues into organs, and organs into systems.

Plant tissues include:

  • Epidermis - a protective outer layer.
  • Parenchyma - packing and food-storage cells; carries out photosynthesis in leaves.
  • Collenchyma and sclerenchyma - provide flexible and rigid support.
  • Xylem - transports water and mineral salts upward.
  • Phloem - transports dissolved food (sugars).

Animal tissues fall into four main groups:

  • Epithelial tissue - covers and lines surfaces (e.g. skin, gut lining).
  • Connective tissue - joins and supports (e.g. bone, cartilage, blood).
  • Muscle tissue - contracts to produce movement.
  • Nervous tissue - carries electrical messages.

Life Sciences Grade 10: Cells, Tissues and the Diversity of Life — Worked Reasoning: Which type of animal tissue covers and lines body surfaces, such as the skin and the lining of the gut?

Life Sciences Grade 10: Cells, Tissues and the Diversity of Life — Worked Reasoning: Name the plant tissue that transports water and mineral salts upward from the roots to the leaves.

Life Sciences Grade 10: Cells, Tissues and the Diversity of Life — Worked Reasoning: Animal tissues are grouped into these main types: epithelial, connective, muscle and nervous. How many main types of animal tissue is this?
