Detailed explanation-1: -1.1 Organs In their turn, the organs are composed of cells, which are mostly grouped into tissues. Vegetative organs support photosynthesis and plant growth, and reproductive organs enable sexual reproduction. In seed plants, the primary vegetative organs are the root, stem and leaf (Figure 1.1).

Detailed explanation-2: -Roots take nutrients from the soil. Stems hold plants up, move food and water inside the plant. Leaves make food for the plant. Flowers contain seeds to make new plants.

Detailed explanation-3: -As a plant’s reproductive part, a flower contains a stamen (male flower part) or pistil (female flower part), or both, plus accessory parts such as sepals, petals, and nectar glands (Figure 19). The stamen is the male reproductive organ. It consists of a pollen sac (anther) and a long supporting filament.
