Lower Vascular Plants Lower vascular plants include divisions Lycophyta‚ Sphenophyta‚ and Pterophyta. Division Lycophyta includes club mosses and ground pines. Sporophytes of these have stems covered with small‚ scaly leaves. Sporangia appear on the upper surface of the leaves and are structures that produce spores. Lycopods have small leaves that each contains one vein that brings water to the leaf from the roots and carries away extra food. Division Sphenophyta is made up of horsetails or scouring

to be rather slow as very little growth could be observed. After the several days of being under the scorching sun the leaves of the tomato plants started to dry up and would fall off at the very touch of it. More water had to be added to them to further hydrate the plants. It was only after around 30 days that a concrete growth could be observed. The plants grew to a reasonable height and needed to be attached to a bamboo stick so as to remain stable. The growths of the tomatoes themselves were

The City Council of Sparkeville is asking that Glimmerville support an plan (which will be outline later in this letter) that will deal with the over population of the “Grass Carp” that has invaded our water ways. As the City Council of Glimmerville is well aware our ecosystem has been unbalance for a while due to the invasion of the “grass carp fish” that was introduced in our aquatic ecosystem to handle and balance our the biotic

secondary. In primary succession plants grow and colonize earth for the first time. In secondary succession plants inhabit and colonize earth that was once inhabited by plants life. A wildfire is one example of secondary succession. When a disturbance in the environment occurs‚ such as a wildfire‚ either part or all of the community is destroyed. The aftermath of the wildfire leaves a barren landscape open to new growth‚ vegetation‚ and re-colonization of plant species (Gurevitch et al‚ 2002)

of bryophytes‚ seedless vascular plants and gymnosperms. Focus your answer on traits (structures or processes) that affect the success of various transitions in the life cycle. How do any of the differences you mention affect the relative success of these different groups in dry environments? All bryophytes‚ for example‚ liverworts‚ mosses and hornworts‚ have the gametophyte generation as the most dominant. Antheridia and archegonia develop on the mature plant (the gametophyte).

Describe five specific situations where pest and disease control measures are required: Vineweevil: This is an insect that attacks a wide range of plants‚ both indoors and outdoors‚ but can be especially damaging to container plants. He needs to be controlled otherwise he will kill the plant. Adult weevils eat plant leaves during spring and summer‚ its the grubs in autumn winter attack the roots of the plants‚ plants growing

Studying the intraspecific competition in water crest plants Introduction: Aim: To investigate how intraspecific competition affects the growth of Nasturtium officinale given an equal amount of water‚ nutrients and sunlight provided. Research Question: To what extent does the spacing between consecutive seedlings of Nasturtium officinale influence the germination‚ and consequently the lengths of the shoots and roots of the plant. Theory: Intraspecific competition occurs when members

Literature The question being asked here would be “Does a plant grow bigger if watered with milk? Or water?” In my opinion the answer would be milk because milk contains vitamins and calcium that water does not have‚ but the answer is to be found out later during the project. Well‚ it is known that for a plant to survive it will definitely need air‚ soil‚ water‚ light‚ and space to grow‚ but maybe if we replaced water with milk‚ plants could grow bigger and quicker‚ you never know. To test my theory

Computerised Environmental Control and Plant Management Systems Report For the new modern state of the art green houses there is the ability to run a computerised plant control system which controls the heat and ventilation of the greenhouse. It is likely that there will be different requirements for the system through the year. Alteration on the computer programme will allow the greenhouse environment to be adjusted which will help the growth of certain plants. Building a state of the art
