The common land plants are thought to have originated 450-500 million years ago from a group of freshwater green algae called charophytes (Domozych). These algae emerged on land and thus spawned the first plants, bryophytes. Bryophytes are non-vascular plants who first appeared 354-409 million years ago in the Devonian period, and are only found on land (Evolution). Since they lived on land, they had little support and relied on their cells’ turgor pressure to keep them upright (Evolution).

Many insect, disease or nutritional problems are much more easily cured or controlled when quick action is taken. If damage is observed too late, treatments may be of little help and production or beauty reduced or destroyed. Frequent observation is important to catch developing problems early. Try to take a daily quick walk through the garden to observe small changes. It will not only solve problems, but can take your mind off your own for a few minutes. In observing nutritional growth problems

Based on the tables seen above, in Trial 1,all the leaf disks in Trial a were the only ones to rise. In Trial 2, only Trial b had its leaf disks successfully rise to the top. In Trial 2c, all the leaf disks rose in all three Trials (a,b, and c). Trial 3’s leaf disks also rose in the shortest amount of time (in minutes). In the control condition for each trial, no leaf disks were observed rising to the top of the beaker/container in which they were placed. From the tables seen above, it can be seen

have long freezes or arid temperatures. This means that Azolla can be found on any continent that has warm freshwater ponds, ditches, slow rivers or lakes. Azolla can be found on every continent except for Antarctica. (1) 2. What is unique about this fern? Why is it called ‘Azolla Superorganism’? (2 pts) Azolla is a superorganism because it has a symbiotic relationship with cyanobacteria. These two organisms are separate beings, but when the Azolla reproduces it passes that bacteria onto it’s offspring

Few tree species are as incredibly fascinating as the quaking aspen. Quaking aspens, or Populus Tremuloides, grow 40 to 100 feet tall, have beautiful black and white bark with dark green leaves, and are shade-intolerant, resulting in their height, straightness of the trunks, and few lower branches (when mature). Quaking aspens also have many uses. Deer and other mammals browse aspens as a winter food source. Native Americans used the sap for cooking. Medicinally, aspen can be used for fever and

This was a multi-week experiment that involved sowing the fern spores in nutrient agar. This allowed for observation and analysis of the life cycle of the C-Fern. With this the experiment could form genetic predictions based on the patterns observed. The cells of the fern are diploid, they contain two sets of chromosomes. The plant is in the sporophyte generation of it life cycle. At some point within the sporophyte plant a few of the cells will divide by meiosis and they will be haploid cells

January 24th, 2014 Forensic Science/ Mod 3 Chapter 5 Test True or False: 1) Pollen is an example of trace evidence. Answer: True 2) Through microscopic examination of pollen or spores, it is possible to identify a specific plant that produced that pollen or pore. Answer: False 3) All Pollen & Spores are produced continuously throughout the year. Answer: False 4) With the exception of bacterial endospores, pollen & spores are reproductive structures. Answer: True 5) Spores are

ETYMOLOGY OF ANDROGRAPHIS PANICULATA A. paniculata is a large genus of herbs found in the Indo-Malaya, Africa, Brazil and also the central of America Northward into Mexico (Alagesaboopathi, 2000). It is an annual plant which grows to the height of 1 – 3 ft. It is one of the most widespread plants used in the Unani and Ayurvedic traditional medicines. It is an erect and branched plant with lanceolate green leaves (Rammohan, 2009) 2.2. DISTRIBUTION OF ANDROGRAPHIS PLANT A. paniculata consists of 28

radiation of songbirds, the integration of Australia and Asia flora and fauna, and finally the tremendous effects of the Pleistocene glacial periods on tropical rainforest vegetation. The Age of the Pteridophytes: This age refers to the Age of Ferns, dating back to about 435 million years ago when the first plants adjusted to life on land. About 500 million years ago, during the Ordovician period, fungi and algae were the

Rubber trees, or scientifically known as Hevea Brasiliensis from Euphorbiaceous family, are particularly prevalent in Thailand, Malaysia, Indonesia, southern part of India and the southwestern part of Sri Lanka [1]. Today, rubber tree has been the main source of natural rubber for use worldwide. It has high export potentials and is rated as one of the most profitable Agri-industrial ventures [2]. Asian’s well known Rubber tree boards are (RRIM) (Malaysia), RRII (India), RRIC (Sri Lanka), and BPM
