Lesson 1
What is a cell?
The basic unit of structure in living things/organisms
What is an organelle? And where are they found?
An organelle is a tiny cell structure that carries out functions--within a cell.
What 2 processes can substances use to move in and out of a cell?
What is every cell surrounded by?
Active or passive transport
A selectively permeable membrane.
What are the 3 main stages of the cell cycle?
What is the cell cycle?
Interphase - Mitosis - Cytokinesis
The series of events in which a cell grows, prepares for division, & divides to form two daughter cells
How do cells make food?
What is the process by which cells make food?
They capture energy from the sun and use it to make food.
Photosynthesis.
What is an organism's structure determined by?
The way it's cells are put together
What is a cell wall, and what organisms have a cell well?
A cell wall is the rigid supporting layer that surrounds the cells of plants, protists, fungi, and other bacteria.
What is passive transport?
What is active transport
The movement of dissolved materials across a cell without using a cell's energy.
What are the 4 stages of mitosis?
What is the longest stage of the cell cycle?
Prophase - Metaphase - Anaphase - Telophase
Interphase
What is the photosynthesis equation?
What are you eating when you eat a plant roots
Light energy + 6CO2 + 6h2O +C6H12O6+6O2
Stored energy
Who discovered cell theory?
Robert Hooke
What is a fungi cell wall made of?
What is a plant cell wall made of?
chitin
cellulose
What is osmosis?
What is endocytosis?
The diffusion of water molecules is the process by which molecules move from a higher concentration to an area with a lower concentration.
When the cell membrane takes large particles into the cell.
What is the difference between cytokinesis in animal cells and plant cells?
What is cytokinesis?
Animal cells: cell membrane squeezes together & cytoplasm pinches into two cells. Plant cells: a cell plate forms across the middle of the cell
The final stage, in which the cell's cytoplasm divides, distributing the organelles into each of the two new daughter cells
Where does the green color come from?
What is the most important sugar produced from photosynthesis?
pigents which are chemical compounds that absorb light.
Glucose
What are the three cell functions?
Obtaining energy, bringing in nutrients and water, and getting rid of wastes
What is a tissue?
What is an organ system?
a group of similar cells that work together to perform a specific function
a group of argans that work together to perform a major function
What is exocytosis?
What is facilitated diffusion?
When the cell membrane allows large particles to move across the cell.
The process by which proteins in the cell membrane form channels through which molecules can pass.
What are the certain parts/phases of interphase?
What are the stages of the cell cycle in order?
Replicating, Growing, and Preparing for Division
Interphase - Prophase - Metaphase - Anaphase - Telophase - Cytokinesis
True or false. Do cells use oxygen during cellular respiration?
What does a cell do when it needs energy?
True
They draw it out by breaking down the energy-rich compounds through cellular respiration.
What is the cell theory?
The explanation of the relationship between cells and living things
What does a plant cell have that an animal cell doesn't have?
What does an animal cell have that a plant cell doesn't have?
chloroplasts
lysosome
What is the function of a cell membrane?
What do cells rely on?
Gets all chemicals to support lif and maintains homeostasis.
Surrounding gasses and liquids
What happens in interphase?
What can cells only be produced by?
The cell copies DNA and prepares to divide into two cells
Other cells
What is the cellular respiration equation?
How you add to your body energy account
C6H12O6 + 6O2 + 6CO + 6H2O + ATP Energy
