Students explore the smallest, but most important units of life: cells. They also gain an understanding of common cell parts through lifelike animations. Additional concepts and terminology include building blocks of life, animal cell, cell membrane, nucleus, cytoplasm, plant cell, photosynthesis, cell wall, chloroplasts, organelles, and role of cells in the body.
Deeply explores the structure of both plant and animal cells. Demonstrates the different types of cells, their components, and their functions
Part of the "Visualizing Cell Processes" series. Includes the following modules: "The Cell Machinery," "A Variety of Cells," "Organic Molecules: The Building Blocks of Life," "Prokaryote Evolution and Diversity," and "Independently Living Eukaryotic Cells."
Introduces cells, how they function, the differences between plant and animal cells, and the various parts of the cell. A quiz is given after each topic.
Uses microphotography and graphics to examine different kinds of plant and animal cells, discussing their structures and tissues. Defines mitosis and meiosis as forms of cell division and illustrates each. Video has three 5-minute segments for convenience.
Part of the "Inside the Living Cell" series. Shows how DNA replicates; how copy errors occur and are subsequently corrected by repair enzymes; and how DNA is compressed into chromosomes, making mitosis and cell division possible. Provides an overview of DNA structure, replicating DNA, mutations that change the genetic code, proofreading and repair, and the stages of mitosis.
Cells differ in size, shape, and function depending on their role in the body. Specialized cells make up tissues, tissues make up organs, and organs make up the systems that work together to make up the body. Join Pinky and Petunia as they discuss some examples of specialized plant and animal cells. Part of "The Amoeba Sisters" series.
Take a look through a microscope at a virus attacking a cell and see the immune system in action. Viruses continue to replicate until they break apart the host cell and start spreading throughout the body, destroying healthy cells along the way. The immune system overpowers a virus with white blood cells and creates the antibodies that kill the same types of viruses quickly if they return.
Part of the "Inside the Living Cell" series. Illustrates how genetic instructions carried on DNA are transcribed into RNA, leading to the production of specific enzymes that control the thousands of biochemical processes occurring in living cells. Provides an overview of the protein basis of life, enzymatic reactions, amino acids and DNA, how proteins are built, and gene activation.
In this episode, Pinky and Petunia discuss examples of prokaryotes and eukaryotes. They also lead a discussion that compares and contrasts these two types of cells. Part of "The Amoeba Sisters" series.
All living things are made from one or more cells. A cell is the simplest unit of life, and they are responsible for keeping an organism alive and functioning. In this episode, Pinky and Petunia discuss the organelles of cells. Part of "The Amoeba Sisters" series.
Part of the "Inside the Living Cell" series. Illustrates the mechanisms of photosynthesis and cellular respiration. Introduces adenosine triphosphate, or ATP, the universal energy carrier molecules that supply energy-hungry reactions. Also outlines the structure and function of chloroplasts and mitochondria, energy transforming organelles. Overviews ATP and chemical energy, mitochondria, aerobic respiration, chloroplasts, and the reactions of photosynthesis.
Every cell in the body is a specific size. Host Trace Dominquez discusses some new scientific findings related to cell growth. A team of biologists has zeroed in on a previously unknown mechanism within the cell growth cycle that controls cell size. They made this fundamental finding by studying yeast cells, but it could provide insight to basic human biology. Part of the "Uno Dos of Trace" series.
Students receive an overview of nutrition basics starting with an in-depth look at nutrients. This program also provides an overview of nutrition standards and guidelines. Part of the "Human Nutrition" series.
Hannah Laccarino, a graduate student in Brain and Cognitive Sciences at MIT, answers questions about the importance of brain cells. She also discusses what happens to the brain cells not used. Part of the "#askMIT" series.
The most common bacterial shapes are rods, cocci (round), spirals and filaments. Groups of these cells can be differently arranged in space. Four 3D-printable models illustrate these shapes and arrangements.
Colony formation on semi-solid medium is basic characteristic of many different bacteria and an important property for microbiologists. These models illustrate the different types of colonies formed, what a colony reflects at the cellular level, how microbiologists obtain isolated colonies, and what happens when cells swarm instead of forming colonies.
Most bacteria grown by fission, one cell dividing into two. When nutrients are abundant, this can result in exponential growth, with a large increase in the number of cells over a surprisingly short period of time. Bacterial cell division and the characteristics of exponential growth are illustrated with four, 3D printable models
Photosynthesis converts light energy from the sun into chemical energy stored in organic compounds, which are used to build the cells of producers and ultimately fuel ecosystems. After providing an overview of photosynthesis, a series of animations describe the inside of the cells of a leaf to explain how the reactions of photosynthesis happen.
Part of the "Inside the Living Cell" series. Provides an overview of the different kinds of cells, emphasizing the fact that all cells have a common organizational structure and carry out similar biochemical processes. Presents the discovery of cells, cell structures, organelle function, cell varieties, and the chemistry of life.
