Cell Organelles
This part of the cell contains DNA and controls cell functions.
What is the nucleus?
This term refers to the outer layer of a plant cell that gives it structure and support.
What is the cell wall?
This is the smallest unit of life in all living organisms.
What is a cell?
True or False: Only Plant Cells have a cell membrane.
False
What are the two types of cell transport?
Passive and Active Transport
This gel-like substance inside the cell holds the organelles in place. Also, chemical reactions take place there.
What is the cytoplasm?
This organelle stores water, nutrients, and waste in plant cells.
What is the vacuole?
What are two examples of organisms?
Humans, animals, plants
What is the term for a membrane’s ability to allow certain molecules to pass through while blocking others?
semipermeable, only some molecules can move in and out of the cell
What is the energy called in Active Transport?
ATP
Known as the "powerhouse" of the cell, this organelle produces energy.
What is the mitochondria?
What is the difference in shape between plant and animal cells?
Plant cells are rectangular and animal cells are circular
Put these terms in order from smallest to largest: organ, tissue, organism, cell, organelle, organ system
organelle, cell, tissue, organ, organ system, organism
In the lab, was starch or glucose able to pass through the membrane and why?
Glucose due to its size
Explain Passive Transport
movement from high to low, doesn't require energy
This part of the cell acts as a protective barrier, controlling what enters and exits the cell.
What is the cell membrane?
Which cell has the larger vacuole and why?
Plant Cells
Multiple organs that work together make up this level of organization.
What is an organ system?
From the lab, what color was the inside of the cell vs. the outside?
Blue-black, amber
Explain Active Transport
Movement from low to high concentration, does require energy
Found in plant cells, this organelle is responsible for photosynthesis
What is the chloroplast?
True or False: Organelles must work together and their activities must be coordinated
True
This is a complete living thing that can perform all life processes on its own.
What is an organism?
What happened when we added salt water to the red onion cell?
The cell wall and cell membrane became more distant.
True or False: Oxygen and Carbon Dioxide can pass through a cell membrane
True they are both small in size
