that mean "naked-seeded‚" in reference to the fact that gymnosperm seeds are produced out in the open on cone scales‚ while the seeds of flowering plants are produced completely enclosed within fruits. In the previous lab we learnt that bryophytes and Pteridophytes of the kingdom Plantae‚ reproduce by spores. In gymnosperms and angiosperms (flowerng plants)‚ however‚ dispersal is primarily by means of seeds‚ which are considerably more complex and larger than spores. In contrast to the branching patterns

discovered in the last ten years. Because of this‚ the rate of endemism for the Philippines has risen and likely will continue to rise. Plants At the very least‚ one-third of the more than 9‚250 vascular plant species native to the Philippines are endemic. Plant endemism in the hotspot is mostly concentrated at the species level; there are no endemic plant families and 26 endemic genera. Gingers‚ begonias‚ gesneriads‚ orchids‚ pandans‚ palms‚ and dipterocarps are particularly high in endemic

Around 4.6 billion years ago‚ our universe was born by accretion from the solar nebula known as the Big Bang. As the sun heated up‚ this orbiting matter accumulated and unavoidable mass of larger bodies collide to successively create protoplanets with its own gravitational pull. During this period‚ Earth was nothing but molten rock from the collision with other bodies and volcanoes‚ temperature reaching over 2‚000 fahrenheit. Not only that‚ but Earth then‚ would’ve been toxic to humans and modern

The small‚ and white larvae hatch and begin chewing away at the vascular tissue to tunnel inside to the wood of the tree. Tunnels are formed throughout the wood as all the larvae eat the wood and grow. These tunnels inhibit the trees growth by not allowing it to properly transport water and nutrients. They pupate inside

is a vascular plant that produces seeds that are not protected by fruit but are hidden in a woody cone. They do not have flowers‚ but most retain their leaves year round. Gymnosperms include over 600 species in four divisions: Conifers‚ Cycads‚ Ginkgoes‚ and Gnetophytes. Most of today’s gymnosperms belong to the conifer division. Gymnosperms are found in most of the world’s regions and take most of the credit for timber and paper products. Angiosperms Angiosperms are vascular plants that

The purpose of this lab was to investigate whether veins affect photosynthesis rate. It was predicted that having veins would decrease the rate because chloroplast might be less frequent due to the vascular tissue. For this experiment‚ 4 groups were set up: veins and no veins in CO2 solution‚ and veins and no veins in distilled water‚ the distilled water groups served as controls. These 4 groups were placed under a light bulb in order for photosynthesis to occur. No disks experience movement in the
