GYMNOSPERMS - phlya Ginkgophyta‚ Gnetophyta‚ Cycadophyta and Coniferophyta - vascular plants with true roots - gymnosperms = “naked seeds” - cones/strobili - have seeds that develop on the surfaces of sporophylls instead of in ovaries like angiosperms - microsporangium produces pollen grains (sperm) and the megasporangium produces the egg - sporophyte generation is dominant - no water needed for fertilization – pollen travels with the wind Pine trees

Eisely states the first types of plants to appear were “wandering fingers of green” that crept along river systems as well as primitive ferns and mosses. b. The reproductive processes of these plants depended on water. These plants did not use seeds to reproduce; rather‚ they used microscopic sperm that traveled through water to fertilize a female cell. 4. Eiseley notes that the appearance of the flowering plants parallels the rise of birds and mammals. How did the rise of flowering plants

radiata (Mung bean) seed? II. TITLE The role of sunlight on the germination of Vigna radiata seed. III. RATIONALE The germination of the seed is a physiological event. The light is one of the most important environmental factors for germination of seeds. The seeds of many species do not germinate in the dark. Vigna radiata seed or Mung bean seed as it commonly called will be used for the study since it can be prepared anywhere with minimum of equipment and preparation. The seed germinates rapidly

Method Of Testing Seed S eed health refers to the health status of a seed. Sowing healthy seeds of high quality is our concern to improve crop yields thus increasing food production. It has a great concern to farmers and seed producing agencies where the disease is high and average yields are low and where more food is needed to feed the ever-increasing population. • RAG-DOLL OR ROLLED TOWEL METHOD – lay seeds in a moist cloth and roll the cloth with uniform folds.

Relate the life cycle of angiosperms to the other phyla of the plant kingdom. ______________________________________________________________________________ INTRODUCTION TO GYMNOSPERMS Gymnosperms are plants with exposed seeds borne on scale-like structures called cones (strobili). Like ferns‚ gymnosperms have a well-developed

that the germination of seeds increments by half affected by blue light (gave by blue glass filters). Plant essentialness is expanded‚ development is quickened‚ stem and leaf development are enhanced‚ and yields are expanded. Gandhare and Patwardhan (2014) conducted a research about the Electric Field Adoption for Germination Improvement. The utilization of electrostatic field prominently affected seed germination. The adaption of electrostatic field is the best strategy for seed improvement. Because
