in stressful environments‚ including drought‚ high winds‚ heat‚ and cold. Some Conifers are the oldest plants on earth‚ growing to over 5‚000 years old. Conifers have either needles or scale-like leaves. They bear cones instead of fruits‚ and their seeds do not have a shell-like outer coating like flowering plants. Plants from the Coniferophyta Division include pines‚ cedars‚ hemlocks‚ cypress‚ juniper‚ larches‚ firs‚ spruces‚ and yews. The Coniferophyta Divsion contains only one Class: Pinopsida

DEVELOPMENT. FLOWER DEVELOPMENT REPORT (ARABIDOPSIS THALIANA) INTRODUCTION. Arabidopsis thaliana is the scientific name used to identify a tiny weed whose common name is ‘mouse ear cress’. It is a dicotyledonous angiosperm since its mature embryo carries two leaves (dicotyledonous) and its seeds are contained in an ovary within the flower (angiosperm). Like many other plants‚ Arabidopsis thaliana is an autotrophic plant capable of producing its own food through photosynthesis. Being firmly

Nutritional requirements The composition of medium for the tissue culture is the most important key factor in the successful culture of plant cells. The medium should be accurately defined of inorganic and organic chemical additives so as to provide i) the nutrients for the survival of the plant cells‚ tissues and organs under culture and ii) the optimal physical condition of pH‚ osmotic pressure‚ etc. In the culture of plant cells formulating optimum type of medium favorable for in vitro

Africa and Asia. It is a warm season plant and not frost tolerant. It is a diploid species with 2n= 16. It is naturalized in Florida and many other tropical and subtropical areas worldwide. Hairy indigo is known to have hard seed and should be scarified for uniform germination. Being hard seeded is beneficial for self-reseeding in pastures and cover crops. This persistence in other crops can cause it to be a troubling weed due to its height‚ canopy and woody stems that can interfere with crop harvesting

ticks from the rhino. Yet‚ despite their seemingly small role in the food chain‚ rhinos play a significant role in their ecosystem. They make paths for other animals when they crash through dense bush. Their dung enriches the soil and contains seeds for germination. When they dig‚ they create pools of water benefitting others like frogs and insects. Interesting facts: • The name rhinoceros means ‘nose horn’ and is often shortened to rhino. • There are five different species of rhinoceros‚ three

Prehistoric humans had many choices as to how they would obtain food. Although all humans in the past started as hunter-gatherers‚ some evolved into farmers. The first farmers were unaware of their actions. They could not have possibly known that they developed food production as they were the first to do so. The decision to change from hunter-gatherers to farmers did not occur simultaneously. Many hunter-gatherers choose to not change their lifestyle. The change occurred gradually and was influenced
