|
||||
| What is the term used to describe an organism made up of a cell without a nucleus? | Prokaryote (Prokaryotic Cells)
🗑
|
||||
| The process by which cells use oxygen to produce energy from food. | Cellular Respiration (Aerobic Respiration)
🗑
|
||||
| The process by which particles move through the cell membrane from an area of higher to lower concentration. | Diffusion
🗑
|
||||
| What is the name of the special process used by eukaryotic cells to prepare the cell's nucleus for cell division. | Mitosis
🗑
|
||||
| A special type of diffusion that only deals with water. | Osmosis
🗑
|
||||
| Who/What contributed to the development of the cell theory? | The discoveries made by many scientists (Hooke, van Leeuwenhoek, Schleiden, Schwann, Virchow) and the invention of the microscope.
🗑
|
||||
| What are the 3 statements of the cell theory? | 1.) All living things are made up of cell.
2.) Cells are the basic units of structure and function in living things.
3.) All cells must come from pre-existing cells.

| Which cell organelle allows certain substances to enter and exit the cell? | Cell Membrane
🗑
|
||||
| Which cell organelle allows certain substances to enter and exit the nucleus? | Nuclear Membrane
🗑
|
||||
| What is the single unit of a chromosome called? | Gene
🗑
|
||||
| Which cell organelle is responsible for making proteins? | Ribosomes
🗑
|
||||
| Which cell organelle stores food, water and waste for the cell? | Vacuole
🗑
|
||||
| What is the name of the jelly-like substance found inside of the cell and contains all of the organelles? | Cytoplasm
🗑
|
||||
| Which organelle is only found in plant cells and used light energy to make food? | Chloroplast
🗑
|
||||
| Which organelle is only found in animals cells and contains digestive juices to break down food, dead/injured cells? | Lysosomes
🗑
|
||||
| This orgnelles is described as the "powerhouse" of the cell and is the site for cellular respiration | Mitochondria
🗑
|
||||
| Which organelle is the internal delivery system for the cell? | ER
🗑
|
||||
| This cell structure contains the genetic code (DNA) for making proteins. | Chromosomes
🗑
|
||||
| All of the activities that a cell performs is controlled by this cell organelle. | Nucleus
🗑
|
||||
| This cell structure is found in plant cells and is used for support and protection | Cell Wall
🗑
|
||||
| What are some characteristics unique to a plant cell? | cell wall, chloroplast, rectangular in shape, has the ability to make its own food, large vacuole
🗑
|
||||
| What are some characteristics unique to an animal cell? | circular in shape, few small vacuoles, cannot make its own food, lysosomes
🗑
|
||||
| How are diffusion and osmosis alike? | Both do not require energy and deal with the movement of a substance from an area of high to low concentration.
🗑
|
||||
| When does a cell use active transport to get things in or out of a cell? | Active transport is used when molecules are too large to fit and when moldecules go against the natural gradient by moving from an area of low to high concentration.
🗑
|
||||
| How are active transport and diffusion different? | Active tranport requires energy and moves materials from low to high concentration. Diffusion does not require energy and moves materials from high to lower concentrations.
