State’s land mass‚ it has 25% of its endangered species. The Hawaiian islands have more endangered species than anywhere else in the world. Currently‚ there are ninety-seven extinct native Hawaiian plants. This paper will cover the history‚ effects‚ and the solutions to protecting native Hawaiian plants. It all started in the 19th century‚ when white settlers came to the Hawaiian Islands. When they arrived‚ and brought goods to the islands‚ they also brought many pests. According to the article

Sperm cells A sperm cell is the male reproductive cell that carries the male portion of chromosomes and deoxyribonucleic acid (DNA) information to be fused with the female egg or ovum. The sperm cell carries various amount of heredity information inside the cell nucleus. There are various ways in which sperm can be transmitted to the

Plant Tissues A mature vascular plant (any plant other than mosses and liverworts)‚ contains several types of differentiated cells. These are grouped together in tissues. Some tissues contain only one type of cell. Some consist of several. Meristematic The main function of meristematic tissue is mitosis. The cells are small‚ thin-walled‚ with no central vacuole and no specialized features. Meristematic tissue is located in • the apical meristems at the growing points of roots and stems. • the

- The major functions of the cell is concentrated at the outer edges of the retina and are used in peripheral vision. On average‚ there are about 125 million rod cells in the human retina. Rod cells are almost entirely responsible for night vision. Rod cells do not process fine details or color differences‚ but are highly sensitive to light. A single flash of light is all that is require to produce a response from a rod cell. Rod cells function as specialized neurons that convert visual stimuli in

Prokaryotic Cell Structure Bacterial Cell Structure Mariana Ruiz Villarreal/Wikimedia Commons Prokaryotes are single-celled organisms that are the earliest and most primitive forms of life on earth. As organized in the Three Domain System‚ prokaryotes include bacteria and archaeans. Prokaryotes are able to live and thrive in various types of environments including extreme habitats such as hydrothermal vents‚ hot springs‚ swamps‚ wetlands‚ and the guts of animals.

DETERMINATION OF THE WATER POTENTIAL OF POTATO TUBER CELLS. Method. Five sucrose solutions with varying molarity and one control containing distilled water were prepared and poured into test tubes. The potato discs were dried‚ weighed and added to the test tubes. The discs were then weighed again after a period of 24 hours. The percentage change in mass was then calculated. Apparatus.  Specimen tubes with stoppers x6  1cm3 diameter cork borer  razor
