or Plasma Membrane; flexible structure that holds a cell together, forms a boundary between the cell and its enviornment, and helps control what enters and leaves the cell
structure of plants, algae, fungi, and many types of bacteria that supports and protects the cell membrane
gelatin like substance inside the cell membrane that contains water, chemicals, and organelles
balloon like cell organelle in the cytoplasm that can store food, water, and wastes, also provide pressure against the cell wall for cellular support in plant cells
takes in nutrients, breaks them down during cellular respiration, and create energy for the cell
process by which plants, algae, and many types of bacteria use sunlight, water, and carbon dioxide to make food and oxygen
are the food producers in a plant cell; photosynthesis takes place here; they absorb light energy from the sun and produce food in the form of glucose sugar from carbon dioxide and water
Deoxyribonucleic Acid (DNA)
the chemical conatined in chromosomes that determines which traits an organism will have
the movement of material from an area where molecules are crowded to an area where they are less crowded
a tiny organelle that contains enzymes specialized to break down ingested materials, secretions and wastes
one of the foundations of biology; six major tenants
1. The cell is the basic building block in all living things.
2. All organisms are made up of one or more cells.
3. Similar cells from similar species are essentially the same in chemical composition.
4. All cells come from the division of preexisting cells.
5. Cells contain genetic material that is passed down to daughter cells during cell division.
6. Energy flow(metabolism) occurs within cells.
