High School Sophomore Lesson Title: Plant Structure Next Generation Sunshine State Standards: Benchmark SC.912.L.14.7 - Relate the structure of each of the major plant organs and tissues to physiological processes. Rationale: Knowledge obtained in this lecture will serve as a stepping stone to aid students in future lectures‚ such as photosynthesis‚ plant cell structure‚ mitosis‚ etc. Knowledge of plant structure is useful to all people‚ as plants are a significant staple in our lives

2012 Tuesday‚ October 9th‚ 2012 Comparing Plant and Animal Cells Abstract The purpose of our lab was to have a better understanding of what are the differences between animal cells and plant cells. Although the cell is the basic unit in both living beings they are not completely alike. For that I have examined and compared human cheek cells to Elodea leaf cells. First‚ I’ve scraped the inside of my cheek with the end of a swab stick to collect the cells then I’ve prepared them on a clean glass slide

Chapter 3 Cell Structure and Function Section 3.1: Cell Theory: Cells are the smallest building unit of living organisms that can carry out all processes required for life. Almost all cells are too small to see without the aid of a Microscope. Although glass lenses used to magnify images for hundreds of years‚ they were not enough to reveal individual cells. The invention of Compound microscope was in the late 1500s by the Dutch eyeglass maker Zacharias Janssen. In 1665‚ the English scientist

Chromosomes- genetic material that is coiled up into structures during cell division. Importance of DNA- genes control the production of proteins..(look like‚ body function‚ body communications‚ and enzyme control) DNA screening- the process of testing individuals to determine whether they have the gene(s) associated

Plant Structure and Function Plant Body The unique organization of tissues in flowering plants is part of the reason why they are the dominant group of the plant kingdom. Monocots and Dicots Meristems Meristems – region of undifferentiated cells that can divide rapidly. Apical meristems – shoots and tip of roots (primary growth) Lateral meristems – thickening of the cambium (secondary growth) Plant Tissues Plant Tissues Xylem – conducts water and mineral ions; fluids can

single cell to divide and produce all the differentiated cells in an organism‚ including extraembryonic tissues. Totipotent cells formed during sexual and asexual reproduction include spores and zygotes. Zygotes are the products of the fusion of two gametes. In some organisms‚ cells can dedifferentiate and regain totipotency. For example‚ a plant cutting or callus can be used to grow an entire plant. Human development begins when a sperm fertilizes an egg and creates a single totipotent cell called

DETAILED DIFFERENCES BETWEEN EUKARYOTIC AND PROKARYOTIC CELLS Cells are divided into two categories namely the Prokaryotes and Eukaryotes. These two have varying differences between them. Speaking in simple cell biology words‚ prokaryotes are primitive‚ simple organisms that lack membranous cell organelles. The opposite of this are eukaryotes‚ which are advanced and complex organisms having membrane bound cell organelles. Seemingly simple in structure and markedly different from eukaryote and
