Cell Division

Essential Question: How do cells grow and reproduce?

Big Idea: New cells arise from the division of pre-existing cells.

Goals:

Describe the events that occur during the cell cycle: interphase, nuclear division (i.e. mitosis or meiosis), cytokinesis
Compare the processes and outcomes of mitotic and meiotic nuclear divisions

2. Cell Biology

2.1 Relate cell parts/organelles (plasma membrane, nuclear envelope, nucleus, nucleolus, cytoplasm, mitochondrion, endoplasmic reticulum, Golgi apparatus, lysosome, ribosome, vacuole, cell wall, chloroplast, cytoskeleton, centriole, cilium, flagellum, pseudopod) to their functions. Explain the role of cell membranes as a highly selective barrier (diffusion, osmosis, facilitated diffusion, active transport).

2.6 Describe the cell cycle and the process of mitosis. Explain the role of mitosis in the formation of new cells, and its importance in maintaining chromosome number during asexual reproduction.

2.7 Describe how the process of meiosis results in the formation of haploid cells. Explain the importance of this process in sexual reproduction, and how gametes form diploid zygotes in the process of fertilization.

2.8 Compare and contrast a virus and a cell in terms of genetic material and reproduction.

Technology Standards:

1.1 Empowered Learner

Students leverage technology to take an active role in choosing, achieving, and demonstrating competency in their learning goals, informed by the learning sciences.

1.3 Knowledge Constructor

1.3.d Students build knowledge by actively exploring real-world issues and problems, developing ideas and theories and pursuing answers and solutions.

1.6 Creative Communicator

Students communicate clearly and express themselves creatively for a variety of purposes using the platforms, tools, styles, formats and digital media appropriate to their goals.

1.6.a Students choose the appropriate platforms and tools for meeting the desired objectives of their creation or communication.

Mitosis allows multicellular organisms to grow, build tissues, and replace cells.
Meiosis enables sexual reproduction and contributes to genetic diversification in each new generation of organisms.

Instructions for Making an Animated GIF:

Open the

Arrange your cells to show each motion sequence.
Go to file/download/jpg or png
Once you've made each part of the sequence, go to: EZGIF.com
Upload your files and select your speed
Download your file
Play your file and narrate what is happening, using screencastify.
Do this for each of the required sequences.

Directions for Creating a Gif in Google Drawings

Screencast an Animation

Using Brush Ninja or SlimAnimation, create an animation

1. Create by drawing with your finger
2. Run the Animation
3. Screencastify an explanation of what is happening in the animation and how it relates to the four types of rigid motion.

Directions for Using Brush

Once you've made each part of the sequence, by taking photos on your device, go to: EZGIF.com
Upload your files and select your speed
Download your file
Play your file and narrate what is happening, using screencastify.

**Tech Tip:

To upload more than one image at a time, hold the control key and click each file.

To upload a series (all in a row,) hold the shift key.
