Amount of Water Effects Plant Growth By Dennis Marchuk Turner Ashby High School Grade 10 March 23‚ 2013 The purpose of this project was to determine how much the amount of water effected plant growth. This had been accomplished by taking three groups of plants and placing them next to one another. Each group contains two plants. Each one would be watered with a different amount of water. They would then be measured how much they grew. The growth of the three plants was compared. Hypothesis:

Botany Essay Questions 1. Pollination is a crucial process of how plants reproduce‚ in which the male sex cell of the flower‚ pollen‚ is transferred from the stamen to the carpel‚ or more specifically‚ from the anther to the stigma. Pollen grains are completely different and unique for each flower‚ they carry the male and female genetic information and it is split exactly 50/50. The transfer is carried out by pollinators‚ which include bees‚ wasps‚ flies‚ butterflies‚ moths‚ several species

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

How to Plant & Grow Moringa The Moringa is a fast growing tree that can reach up to 3 meters in its first year. Moringa is an ideal plant to grow in your own backyard. Get a little Moringa in your diet‚ you can grow your own multivitamin! The Moringa tree grows to about 10 tall‚ with drooping branches. It thrives in subtropical and tropical climates‚ giving fruit and flowers continually. However Moringa grows best in dry‚ sandy soil. This makes it an ideal tree to grow in semi-desert conditions
