Meiosis: An Interactive Animation Diploid Cell (2N): From a preceding mitotic division, the Oogonium (Spermatogonium) enters meiosis with DIPLOID (2N) chromosomes but TETRAPLOID (4N) DNA. Chromosomes then duplicate to produce SISTER CHROMATIDS (or HOMOLOGOUS DYADS). Prophase I: Dyad pairs align to create "TETRADS", non-sister chromatids connect and trade sections at a "CHIASMA", a process called "CROSSING OVER". Metaphase I: SPINDLE FIBERS attach to each dyad at the KINETOCHORE. Anaphase I: Chiasmata break apart and sister chromatids begin migrating toward opposite poles. Telophase I: CLEAVAGE FURROW forms beginning the process of CYTOKINESIS (cell division). Prophase II: Spindle formation begins and centrosomes begin moving toward poles. Metaphase II: Tension from spindle fibers aligns chromosomes at the metaphase plate. Anaphase II: CHROMATIDS separate and begin moving to the poles. Telophase II: CLEAVAGE FURROW forms beginning CYTOKINESIS. Gamete (1N): NUCLEAR ENVELOPES form and chromosomes disperse as CHROMATIN.
Using Animation to Study Cell Structure Overview | How can animations help convey the dynamic nature of cellular processes? What can we learn from animation that cannot be learned as easily from still images? In this lesson, students watch high-definition animations that depict the processes of DNA transcription and translation, and then write voice-over scripts. Materials | Science textbooks, computers with Internet access, projection equipment Warm-Up | Show the animation “The Inner Life of the Cell.” Afterward, ask: What is this video about? Next, show the Times video “The Animators of Life”: Note that in the video, Robert A. You may wish to pause and rewind the video to give students time to jot down the colorful words and phrases, and even the body language, Dr. Related | In the article “Where Cinema and Biology Meet,” Erik Olsen reports on the growing field of scientific animation: Dr. Read the entire article with your class, using the questions below.

Plants - Interactive Science Games and Activities plants A plant is a living thing. A plant needs light, warmth, water and nutrients to grow well. Roots take up water and nutrients from the soil. They also keep the plant steady and upright in the soil. The stem carries water and nutrients to different parts of the plant. The leaves make food by using light from the sun, along with carbon dioxide from the air and water.

How plants work - Science (4) - ABC Splash - Overview Plants are the only living things that can make their own food. They do this during the day while it's light, using a process called photosynthesis, which uses carbon dioxide and produces oxygen. 5 mins 11 secs Source: Kids in the Garden | Learning area: Science | Primary: Year 4 Transcript 00:00:19:06NICK HARDCASTLE:Mmm! ...Read more > 00:00:36:08VOICE:Yummy!

Zygote | 3D Human Anatomy for Animation, Illustration, CAD and Software Development Human Body Maps | 3D Models of the Human Anatomy Different organs can work together to perform a common function, like how the parts of your digestive system break down food. We refer to an integrated unit as an organ system. Groups of organ systems work together to make complete, functional organisms, like us! There are 11 major organ systems in the human body. The circulatory system is a body-wide network of blood, blood vessels, and lymph. Learn more about these body parts in the circulatory system: Every tissue within the body requires oxygen to function. Learn more about these body parts in the respiratory system: The skeletal system gives the body its basic framework, providing structure, protection, and movement. The muscular system is comprised of the sum total of muscles throughout the body that move the skeleton, maintain posture through steady contraction, and generate heat through cell metabolism. The nervous system allows us to perceive, comprehend, and respond to the world around us.

Tree of Life Web Project The Tree of Life Web Project (ToL) is a collaborative effort of biologists and nature enthusiasts from around the world. On more than 10,000 World Wide Web pages, the project provides information about biodiversity, the characteristics of different groups of organisms, and their evolutionary history (phylogeny). Each page contains information about a particular group, e.g., salamanders, segmented worms, phlox flowers, tyrannosaurs, euglenids, Heliconius butterflies, club fungi, or the vampire squid.
