Contains cell’s DNA in the form of genes – controls the cell’s activities. It plays a role when a cell divides or reproduces (mitosis)

Creates a flexible, semi-permeable barrier around the cell that lets materials like nutrients, water, waste and gases like oxygen and carbon dioxide cross the membrane (acts as a filter). It’s the outermost layer of an animal cell. It is underneath the outer layer (cell wall) of a plant cell.

Materials move through this to get to other parts of the cell (like a lazy river!). Controls the movement of nutrients through the cell. It also provides support and shape for the cell.

Organelle where cellular respiration takes place. Energy from food is released (process called cellular respiration). If this organelle is damaged, the cell won’t be able to release energy from nutrients.

This organelle breaks down waste products in the cell. “Clean up Crew”. Gets rid of unwanted material in the cell (old worn out organelles, harmful microorganisms, etc.). It works with the cell membrane to remove waste from the cell.

This organelle is only found in Plant Cells. This organelle is where Photosynthesis takes place. Plant cells obtain nutrients by converting carbon dioxide and water into nutrients (sugar = glucose) using sunlight. Like a “solar panel” – uses the sun to create energy.

This structure is only found in Plant Cells. Provides protection and support for the plant to stand up against gravity, especially when water vacuole is full and pressing on the cell wall. External support.

This organelle stores water, food, and waste for cell. Much larger in a plant cell.

All cells must be able to remove waste to maintain _____________________________ (stable internal environment).
