Plant and Animal Tissues: Mechanism
≈ 24 minMechanism
Follow the mechanism step by step and distinguish what causes the change from what is merely observed.
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 — Mechanism: 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 — Mechanism: 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 — Mechanism: Animal tissues are grouped into these main types: epithelial, connective, muscle and nervous. How many main types of animal tissue is this?
