|
|
||||
|---|---|---|---|---|---|
| Metabolism | The sum of all the chemical reactions that occur in a cell
🗑
|
||||
| Homeostasis | Maintaining a balance internally, even when external factors change
🗑
|
||||
| Cell | building block of all living things
🗑
|
||||
| Cellular Respiration | breaking down nutrients to release energy (glucose + Oxygen → Carbon dioxide and water)
🗑
|
||||
| Chloroplast | part of a cell that turns sunlight into a food source (photosynthesis)
🗑
|
||||
| Diffusion | movement of particles from high concentration to low (with the concentration gradient). No energy required.
🗑
|
||||
| Active Transport | movement of particles from low concentration to high (against their concentration gradient). Requires energy (ATP)
🗑
|
||||
| Mitochondria | in all cells. It’s where sugars are broken down to make ATP (energy)
🗑
|
||||
| Organ system | collection of organs doing a similar job (accomplishing a goal)
🗑
|
||||
| Organism | collection of organ systems, making a whole living thing.
🗑
|
||||
| Tissue | collection of cells doing the same job
🗑
|
||||
| Organ | collection of tissues doing the same job
🗑
|
||||
| Organelle | functional parts of a cell. Each one has a different job.
🗑
|
||||
| Ribosome | little dots in cytoplasm or on the ER. All cells. Make proteins.
🗑
|
||||
| Nucleus | control center of the cell. Contains the genetic information.
🗑
|
||||
| Synthesis | “to make,” usually referring to substances in the body like proteins
🗑
|
||||
| Excretion | getting rid of waste products
🗑
|
||||
| Glucose | A simple sugar C6H12O6 (1:2:1). Needed by all living things for energy
🗑
|
||||
| Amino Acids | the building blocks that are assembled into proteins at ribosomes
🗑
|
||||
| Cell membrane | differentially permeable outer border of cells. It is a phospholipid bilayer
🗑
|
||||
| Cell respiration | energy producing reaction that occurs at mitochondria. Sugars are broken down to release energy (ATP), carbon dioxide and water.
🗑
|
||||
| Circulation | movement or cycling of materials in an organism
🗑
|
||||
| Cytoplasm | the fluid environment inside cell, it’s mainly water.
🗑
|
||||
| Digestion | the process that breaks large food molecules (carbohydrates, proteins, lipids) into smaller pieces for absorption into the bloodstream
🗑
|
||||
| Enzymes | proteins that speed up chemical reactions in living things
🗑
|
||||
| Hormone | a chemical made by the endocrine system that travels to body tissues and causes a response
🗑
|
||||
| Immunity | the body’s ability to destroys pathogens (foreign invaders) before they cause disease
🗑
|
||||
| Inorganic | a chemical that does not contain Carbon and Hydrogen
🗑
|
||||
| Organic | a chemical that contains Carbon and Hydrogen
🗑
|
||||
| Receptor molecule | proteins in the cell membrane that receive chemical messages from other cells
🗑
|
||||
| Reproduction | process by which organisms make new organisms
🗑
|
||||
| (Cellular) Respiration | process that releases energy found in chemical bonds so it can be turned into usable energy. Occurs in the MIGHTY mitochondria
🗑
|
||||
| Vacuole | a storage sac within a cell that may contain substances like food, water or wastes
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
