Animal and Plant cells consist of most of the same cell types‚ but the whole shape of the cell is quite different. An animal cell is a round‚ uneven shape‚ whereas the Plant cell has an affixed shape. They have a more of a rectangular shape. Chloroplast‚ Vacuole and the Cell wall are only found in Plant cells. The Chloroplast is the organelle for the whole system of Photosynthesis. Chloroplasts are found in mesophyll cells (which are found in the leaves) of green plants. They convert light into

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

Plants grow when put under a sunlight. If a plants is placed under a red light‚ a blue light‚ a green light‚ and sunlight then which will grow the most? The hypothesis was if a plant is placed under a blue‚ red‚ green and sunlight‚ then the plant under the green light will grow the tallest of all plant. The experiment’s independent variable was the type of light the plant is placed under. The dependent variable was the growth of plants (in cm). Some variables that were ceped the same was the amount

Legend of the Banana Plant In the early days when the world was new‚ spirits and ghosts lurked everywhere. They lived in gloomy caves‚ they hid in anthills and tree trunks they frolicked in nooks and corners under the houses. In the dark‚ sometimes their tiny voices could be heard dimly‚ or their ghostly presence be felt. But they were never seen. It was during these days of phantoms and unseen spirits that a young and beautiful girl lived. Her name was Raya‚ and she was a girl bold and daring

Genetically Modified Plants and Animals Why should we know about the genetic modification of plants and animals? In this world today we are seeing different labels on our foods but does anyone even really know what they mean? For example what is the difference between a regular tomato and an organic tomato? We should know what foods we are consuming and how they affect our bodies. I believe that more regulations should be put into place by the Food and Drug Administration so that we are better
