Q1: Define bryophytes and state two characteristics.
Bryophytes are small, non-vascular land plants that lack true roots, stems, and leaves. Two characteristics:
1. Absence of vascular tissue (xylem and phloem); water and nutrients absorbed and transported by diffusion.
2. Require moist environments for reproduction; possess flagellated sperms requiri...
Q2: What is alternation of generations? Explain with reference to ferns.
Alternation of generations is the occurrence of two distinct multicellular forms in the life cycle of an organism: a diploid sporophyte and a haploid gametophyte, each reproducing by different methods.
In ferns:
- Sporophyte (diploid, 2n): The large visible fern plant with roots, stems, and fronds....
Q3: Name five adaptations of seed plants to terrestrial life.
Five adaptations of seed plants to terrestrial life:
1. Vascular tissue (xylem and phloem): Allows transport of water, minerals, and nutrients throughout the plant, reducing dependence on external water.
2. Roots: Anchor plant and absorb water and minerals from soil.
3. Waxy cuticle: Reduces water l...
