Veda Bites are swipeable micro-lessons — each one teaches exactly one
idea. Here's a taste from this kit; the app has the full deck.
💡 Key Idea
Tissues: The Building Blocks of Life
Cells team up to form tissues.
In multicellular organisms, cells are organized into tissues. A tissue is a group of similar cells that work together to perform a specific function. This division of labour allows organisms to grow larger and more complex.
↳ Tissues are groups of similar cells performing a specific function.
📖 Definition
Meristematic Tissue
Growth happens here.
Meristematic tissue is found in growing regions of plants. Its cells divide actively to produce new cells, leading to increase in length (primary growth) and thickness (secondary growth).
↳ Meristematic tissue is responsible for plant growth.
📖 Definition
Permanent Tissue
Once grown, cells specialize.
Permanent tissues are derived from meristematic tissue. Their cells have lost the ability to divide and have taken up specific roles. They are classified into simple and complex tissues.
↳ Permanent tissues are specialized and non-dividing.
