  • FERN

  • FrondThe coiled fiddlehead of fern leaves are rooled-up leaf buds. Fiddleheads are formed by a pattern of growth called circinate vernation, as shown in this Blechnum fern.

  • Fern sporangia . Most ferns have sporangia aggregated into clusters, called sori, on the undersides of the leaves.

  • In some ferns, such as the marginal wood fern (Dryopteris marginalis), each sorus is covered by a flap of leaf tissue called an indusium.

  • EPIPHYTEGrows upon another plant (such as tree) non-parasitically or sometimes upon other objects ( such as a building or telegraph wire). Derives its moisture and nutrients from the air and rain and sometimes from debris accumulating around it.

  • Equisetum (Equisitophyta)Its stem is the dominant photosynthetic organ of the plant body.The conspicuous feature of the stem is the series of joints formed by a whorl of small leaves.The leaves are fused along most of the length of the stem, but their brown tips give the appearance of a collar around the stem at the joints.

  • Strobili, or cones, are aggregations of closely packed sporangium-bearing branches or leaves.

  • BRYOPHYTE

  • This is a type of thallose liverwort. During sexual reproduction, spores produced in the capsule germinate to form independent male and female gametophytes. Marchantia also reproduces asexually by fragmentation and gemmae.Gemmae cup

  • GYMNOSPERM

  • Pinophyta (common name: conifers)The leaves are scale-like.No fascicles.

  • CARNIVOROUS PLANTPERIUK KERANephenthes sp.

  • Derive some or most of their nutrients (but not energy) from trapping and consuming animals or protozoan, typically insects and other arthropod.

  • Carnivorous plants appear to adapt and grow in places where the soil is low in nutrients.

  • Female part of Nepenthes sp.Male part ofNepenthes sp.

  • PERIUK KERA
