Animal cells contain many organelles, including the nucleus, which is the control center of the cell. Animal cells also possess a cell membrane, which allows certain materials to flow in and out of the cell.
The splitting of a parent cell into two new cells is called cell division.
The nucleus acts as the cell's brain or control center, regulating cellular activity.
Chloroplasts are the places in plant cells where photosynthesis occurs. Chloroplasts contain chlorophyll.
The cytoplasm contains large amounts of water, as well as chemicals and structures that help carry out the life processes of the cell.
The endoplasmic reticulum transports materials throughout the cell. Attached to the endoplasmic reticulum are ribosomes, which direct the production of proteins.
The golgi apparatus transports materials throughout and out of the cell.
Lysosomes contain enzymes that break down food particles. They also digest old parts of the cell when they lose their effectiveness.
Food and water move through the cell membrane into the animal cell, while waste products cross the cell membrane to exit the cell.
This interactive feature describes some of the most important structures and functions of the cell membrane.
Organelles called mitochondria are largely responsible for carrying out respiration in cells.
Students will create a meme based off of cell organelle function.
Organelles are the structures within cells that break down food, move water, and store nutrients.
Use your cell phone to explore the mini-scopic world. Open your eyes to the amazing world of the ultra-tiny when you convert your cell phone into a portable, picture-taking Miniscope using a simple plastic lens from a laser pointer.
This task presents a real-world problem requiring the students to write linear equations to model different cell phone plans. Looking at the graphs of the lines in the context of the cell phone plans allows the students to connect the meaning of the intersection points of two lines with the simultaneous solution of two linear equations.
After reviewing the positives and negatives of cell phones and cell phone usage safety tips, students will explore a scenario in which a friendly relationship turns to a bullying one involving cell phones and computers.
This simple task assesses whether students can interpret function notation. The four parts of the task provide a logical progression of exercises for advancing understanding of function notation and how to interpret it in terms of a given context.
