Plant cells, tissues, insects, macro-invertebrates and micro-organisms.
Plant cells are grouped into tissues based on similar characteristics, then into five distinct structures (organs).
- Cells – Individual building blocks for life processes and growth. Common cells contain genetic matter (deoxyribonucleic acid, or DNA) and metabolic organelles but they are mostly water. In green plants, they are the site of sugar production (photosynthesis)
- Tissues – Groups of cells that are similar in appearance and function,
- Micro-organisms – Groups of tissues working together with a common function, (e.g., roots, stems, leaves, flowers, fruits, and seeds).
- Plant – Made up of a number of coordinated structures to form a working unit.
