Cell Theory and Scientists
The scientists who build his own microscope and used it to study nature.
Robert Hooke
One function of cells is obtaining ___.
Energy
This structure is found in both plant and animal cells and controls what enters and leaves the cell.
Cell membrane
This instrument allows scientists to make very small objects appear larger.
Microscope
This process allows plants to make food using light energy.
Photosynthesis
Cell Theory states that all living things are made up of these.
Cells bring in these two things that they need.
This strong supporting structure is found in plant calls but not animal cells.
Cell wall
This microscope feature describes how much larger an object appears.
Magnification
This organelle creates large amounts of energy during cellular respiration.
Mitochondria
According to Cell Theory, all new cells come from these.
Existing cells
Cells must get rid of these materials that they no longer need.
Wastes
This organelle is found in plant cells and is where photosynthesis takes place.
This microscope feature allows you to see more detail.
Resolution
Photosynthesis does this with energy.
Cells are the basic units of ___ and ___ in living things.
Structure and Function
Put these in order from smallest to largest:
organ - cell - organism - organelle - tissue - organ system
Organelle - cell - tissue - organ - organ system - organism
Plant cells usually have one large one of these, while animal cells usually have several smaller ones.
Vacuoles
True or False: Microscopes use both magnification and resolution.
True
Cellular respiration does this with energy.
Releases energy
Give all three key points of Cell Theory.
1. All living things are made up of cells.
2. Cells are the basic units of structure and function in living things.
3. All new cells are produced from existing cells.
Name all three functions of cells.
1. Obtaining energy
2. Bringing in nutrients and water
3. Getting rid of wastes
Name three differences between plant cells and animal cells.
1. Plant cells have a cell wall, and animal cells do not
2. Plant cells have chloroplasts, and animal cells do not
3. Plant cells usually have a larger vacuole than animal cells
Cell Theory was able to develop because advancements in this allowed scientists to observe cells.
Technology of the microscope.
Complete the photosynthesis equation:
Light Energy + ______ + ______ → Oxygen + ______
Light Energy + Carbon Dioxide + Water → Oxygen + Glucose
