Plants Organs As was noted in the previous chapter‚ most plant cells are specialized to a greater or lesser degree‚ and arranged together in tissues. A tissue can be simple or complex depending upon whether it is composed of one or more than one type of cell. Tissues are further arranged or combined into organs that carry out life functions of the organism. Plant organs include the leaf‚ stem‚ root‚ and reproductive structures. The first three are sometimes called the vegetative

IB Biology HL Y1 15 January 2009 The Effect of Humidity on Transpiration in Plants Problem/Aim How does placing a plant in a more humid location for 50 minutes affect its rate of transpiration? Introduction Transpiration is the loss of water from a plant‚ mainly through the stomata of leaves. Darkness‚ internal water deficit‚ and extremes of temperature tend to close stomata and decrease transpiration; illumination‚ ample water supply‚ and optimum temperature cause stomata to open and increase

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
