Biology Assignment Transpiration rates between Exotic vs. Native plants In this investigation we will be looking at transpiration. The topic we will be focusing on is transpiration rates between native plants as well as exotic plants. We will be experimenting with 2 native plants as well as 2 exotic plants. The reason we are experimenting on this topic is because of Australia’s dry weather‚ we are wanting to find out which plants will be able to hold more water during Australia’s peaking tempretures

effects of caffeine on plants are not as well developed. Many experiments were done on the effects of caffeine on plants yet; scientists are still confused on the topic. Plants are an important aspect of the ecosystem. Water‚ sunlight‚ and rich soil are all key elements of plant growth and development. Balance is an important concept in plant growth‚ too much or too little water is harmful to plant. Water helps the plant by giving it key nutrients. Without water the plant becomes physically weak

Totipotent cells formed during sexual and asexual reproduction include spores and zygotes. Zygotes are the products of the fusion of two gametes. In some organisms‚ cells can dedifferentiate and regain totipotency. For example‚ a plant cutting or callus can be used to grow an entire plant. Human development begins when a sperm fertilizes an egg and creates a single totipotent cell called zygote. In the first hours after fertilization‚ this cell divides into identical totipotent cells. Approximately four days

Equipment • Cheap plants in three even groups • Three similar sized containers • A ready supply of water • A modern microwave • A ruler • Soil • Measuring cup • Record book Method After the all the equipment is bought‚ the first step to replicate this experiment is to place the three plant group in each of the containers‚ filling the container to around three quarters of the way up‚ not covering the plant. In my case the plants I used were spinach sprouts‚ with two sprouts in each ice-cream

Plant Transport Plants are mostly made up of water. Lettuce is about 94% water and a potato is about 77% water. Plants need water for three main purposes: ------photosynthesis‚ -support -transport of chemicals Water is a raw material for photosynthesis. If water is in short supply‚ the rate of photosynthesis will be limited. Plants need water for support‚ otherwise they wilt. Water is needed to transport many chemicals within plants. Chemicals‚ such as mineral salts‚ dissolve in water and

Plants and humans are perhaps the most important organisms‚ however‚ us humans‚ have caused the death of thousands of plants by starting fires and by cutting down trees for things such as paper and furniture. Plants make oxygen which is very important for our survival; we can’t live without it. In the year 2003 alone‚ 774500 acres of land‚ that contained not only threes but animals too‚ were burned in California (Jane Strong‚ 2003). Some of this land was burned due to natural fires but some of it

The C4 & CAM Pathway Many plant species that evolved in hot‚ dry climates fix carbon through alternative pathways. Under hot and dry conditions‚ plants can rapidly lose water to the air through small pores called stomata. Stomata (singular‚ stoma)‚ are usually located on the undersurface of the leaves. Plants can reduce water loss by partially closing their stomata when the air is hot and dry. Stomata are the major passageways through which CO2 enters and O2 leaves a plant. When a plant’s stomata are

With the worlds population growing constantly quicker and more reliable ways to produce foods need to be made. Through hydroponics more plants and crops can be created in a shorter amount of time. "Hydroponics is an excellent method of conducting research with controlled conditions of nutrient availability." The problem is that if the exact amount of minerals are not used the produce may have negative side effects or unwanted results. Through the research of hydroponics the less fortunate can

Investigating the Effects of Plant growth within Abstract This experiment was conducted to determine whether or not those plants can grow in low fertilized‚ less sun light and the control group. Each group had there own task of making sure that the plants were always water‚ each plant had the same amount of light on them. When the plants started to evolve each individual plant was measured of the height. Most of the plants grew faster than others but over the period the plants that grew faster started

determination in plants Summary- Evolutionary transitions happened gradually from hermaphroditism to monoec in which multiple sex determining genes are involved which include male-sterility and female-sterility factors. There should not be any recombination between different loci which is the pivotal reason for the genetic degeneration of Y chromosomes. There are several theories attached to Y chromosome degeneration that are reviewed recently . Introduction: why are plant sex chromosomes of
