Cell Structure
Question | Answer |
---|---|
What is the Chloroplast function? | water and carbon dioxide gas to produce food for the plant. Chloroplasts capture light energy from the sun |
Exocytosis | The process where the cell's vesicles release their contents outside of the cell |
Endocytosis | The process where the cells take in a substance by surrounding it with a membrane |
Mitochondrion | processes of respiration and energy production occur. |
Vacuole | Organelles that store food, water, and waste material |
Osmosis | The diffusion of water molecules only through a cell membrane |
Describe a plant cell: | A plant cell is a eukaryotic cell that has structures that an animal cell doesn't have these are cell wall, a large vacuole, and chloroplast |
What is the Cell membrane's function? | the membrane is to protect the cell from its surroundings |
What is the Mitochondria's function? | Powerhouse of the cell |
What is the Central Vacuole's function? | to provide structure and support for the growing plant. |
What is the Nucleus's function? | 1) To store DNA 2) It coordinates the cell's activities, which include growth |
Cell membrane | A flexible covering that protects the inside of a cell from the environment outside of the cell. |
Cell wall | A stiff structure outside the cell membrane |
facilitated diffusion | When molecules pass through a cell membrane using special proteins called transport proteins |
Active transport | The movement of substances through a cell membrane only by using the cell's energy |
Carbohydrate/example | One sugar molecule, two sugar molecules, or a long chain of sugar molecules / GLUCOSE |
Describe an animal cell: | All animal cells are made of eukaryotic cells that have a nucleus and organelles. These organelles carry out specific functions. |
What are the reactants/products of photosynthesis? | Reactants- light energy, water, carbon dioxide, and chlorophyll Products- glucose (sugar), oxygen and water. |
What are the reactants/products of cellular respiration? | The main product of cellular respiration is ATP, waste products include carbon dioxide and water. |
What do plants need to survive? | air, water, nutrients, and sunlight |
What is the Cell wall's function? | is to give the cell strength and structure, and to filter molecules that pass in and out of the cell. |
Nucleus | The part of the eukaryotic cell that directs cell activities and contains genetic information |
