Micro-scopes
What was invented 400 years ago that helped people to learn that there are cells in living things?
Microscopes
All cells do this ________.
Perform many basic functions.
What is the external (outside) boundary of an animal cell called? What does this "boundary" part of the cell do?
Cell Membrane
Controls what gets into the cell and what gets out from the cell.
This organelle ____can be found only in plant cells. What does this organelle do for the plant cells?
Cell Wall - Helps to keep the shape of the plant cell, provides support, helps control what does in and out of the cell.
smaller than plant and animal cells
This object _____ was looked at under a microscope hundreds of years ago. The scientist noticed that there were rows of tiny rectangles that he called _____.
cork; cells
All cells are filled with this substance ______.
Cytoplasm
Cytoplasm is important to a cell because it does these things for a cell _____________ and __________.
What part of a cell is the control center of the cell? What can you find in the control center?
It provides the organelles a gelatin like fluid to float in. Chemical reactions happen here. It gives the cell its shape.
The nucleus; DNA
You can find this green organelle ________ in some plant cells. What is the job of this organelle?
The chlorophyll in this organelle does this____ to plants.
Chloroplasts - captures energy from the sun, makes food for plants.
Gives them their green coloring.
Bacteria do NOT have this organelle _____ (it is very important to animal and plant cells.)
Nucleus
Explain why cork would have rows of cells (as seen under a microscope.)
Cork comes from tree bark and trees are living things, so they have cells.
Within the cytoplasm of each cell there are active structures called __________________.
Double your score - Tell some (2) the jobs of these structures.
Organelles
Jobs - process energy, manufacture substances, move materials, provide storage
Which organelle is called "the powerhouse of the cell"? Explain why it has that name. In which cells will you find large numbers of this organelle?
Mitochondria - It releases energy from the break down of food. You can find this in muscle cells (and others.)
What is the name of the "blob" looking organelle that contains water? What is the job of this organelle? What happens if this organelle doesn't have enough water in it?
Vacuole - It maintains the water balance and pressure inside the plant cell.
It will shrink and if many shrink the plant will droop.
Bacteria do have the combination of both of these organelles - you can not find both in either the animal or plant cell.
Cell membrane and Cell wall
Name two types of microscopes and tell what scanning technology creates.
Double your points - Why do you think scanning technology could be very helpful?
Light microscopes, electron microscopes
3-D images
Helpful - medical purposes, safety purposes, development or discovery purposes....other ?
Cells are like a restaurant because they do these things ________ (tell 3 things).
Take in nutrients, make and store chemicals, make and break down substances (materials.)
This organelle_____ looks like a bunch of tubes that go from the nucleus to the cell membrane. It can be "rough" or "smooth". Protein making black dots can be found in the "rough" type and is called ________. The "smooth" type processes these substances____.
The Endoplasmic Reticulum
Black dot - ribosomes
Smooth - lipids
Which structures (organelles) are not found in each- animal and plant cells?
mitochondria cell membranes chloroplasts
Golgi Apparatus
Cell membrane - only found in animal cells
Chloroplasts - only found in plant cells
Bacteria can come in a few shapes. Name the shapes and then draw an example of each on the board.
Sphere - like a ball
Rods - like a pill capsule
Spirals
Tell why the invention and further development of microscopes has been so important. Relate your answer to cells and cell theory.
All living things are made from cells and cells are the basic units of life. Microscopes allow us to learn, study, and experiment with these tiny structures.
A cell carries the instructions to direct all cell activities. Tell 2 of the many activities that cells know how to do.
Cell division or reproduction, how to interact with other cells, and how to remove unnecessary materials from within the cell.
This organelle ____was named after an Italian Scientist. What are some of the jobs of this organelle?
This organelle ____ works like a recycling plant. What does it do?
The Golgi Apparatus - sorts, packages, and delivers proteins and other cellular substances to areas inside the cell membrane.
Lysosome - breaks down nonworking parts of the cell and uses pieces to build new parts.
Tell the name of the organelle that does each job.
A - captures energy B - releases energy
C - waste and recycling management
D - makes proteins E - move and stores material
F - control center
A - chloroplasts B - mitochondria
C - lysosome D - Ribosomes
E - Golgi Apparatus F - Nucleus
Tell what you know! Tell 4 things that you have learned about bacteria.
Responses should come from either the text material or the jeopardy questions in this game.
