Summary Introduction
Introduction:
The dermal tissues are the outermost layer of the plant that provides protection to the plants. Vascular tissues are present in the stems, leaves and the roots of the plants that help in the transportation of food and minerals across the plant. Ground tissue makes the bulk of the plant mass. Meristematic tissues help in the growth of new cells.

A team of researchers investigated the effects of phosphorous availability and light intensity on an angiosperm species. Seeds of the angiosperm were divided into four equal groups. Groups 1 and 2 were exposed to 200 pmol, and Groups 3 and 4 were exposed to 500 umol. Groups 2 and 4 also received a phosphorous (P) solution. After 20 days, all plants were weighed, and the average dry weight of each group was calculated. The results are in the table below. Group 1(200 pmol, Group 2(200 umol, Group 3 (500 umol, Group 4 (500 pmol no P) no P) +P) Average Dry weight (g) Describe the effects of light and phosphorous on the growth of the plants in this study. Explain how the metabolic processes associated with the plant kingdom likely influenced these results. 10.8 1.5 6.2

As he cuts open the papaya, they discover great numbers of slime-covered seed inside, surrounded by soft flesh and soft skin. Before papaya fruits ripen and the seeds inside them mature, their flesh is bitter or sour. Only later does it become tasty. Discuss how this feature improves the odds for the plant's reproductive success and identify the possible agents to disperse the seeds.arrow_forward
