That all living things have basic cells, yeah Anton believes it Define cell:

The basic unit of all living things!

What was Anton van Leeuwenhoek’s contribution to cell discovery? In 1674 Anton van Leeuwenhoek was the first scientist to look at pond water through a microscope (he designed and built many microscopes during his life). In the water he found tiny one-celled organisms. He then looked at the plaque from his teeth under a microscope and saw cells within the substance. Anton was credited with viewing the first living animal and bacteria cells under a microscope.

List the 3 parts of the cell theory 1. All living organisms are made of cells 2.

Cells are the basic unit of structure and function in living things

3. All cells are produced from other cells The first to see it Hooke was wow’d by a cork When he put it under a microscope What was Robert Hooke’s contribution to cell discovery? In the 1600s Robert Hooke was the first to look at cork under a microscope. He noticed that it looked like honey-comb. This action resulted in him being credited for discovering plant cells by viewing the cell walls in this cork tissue. He actually called these “cells” (and was the first to do so) because the boxlike spaces in the cork reminded him of the living quarters in a monastery….called cells. He was the first scientist to discover the idea of cells and coin the term.

Plants have cellular walls, but we don’t need them at all What is the shape of a plant cell?

rectangular

What is the function of the cell wall?

provide support and protection

Only

plant

cells contain a cell wall.

Our little membranes are flexible and strong Why don’t our cells (animal cells) have a cell wall? Animal cells do not have this wall, and are more circular and flexible. Instead, animal cells have a strong and flexible cell membrane that can bend and move to fit into tiny spaces. This allows the animal the ability to move around much more freely than a plant or something like a tree.

They pack their vacuoles in What is the function of a vacuole? the plant cell has vacuoles where extra sugar/food generated from sunlight can be stored for later use. What type of cell contains large vacuoles?

Plant cells

With chloroplast they begin Collecting sunlight Afraid of the dark again What is the function of a chloroplast?

This green substance, chlorophyll,

which is found in the chloroplasts, collects sunlight and converts it into sugar that the plant then uses as energy What type of cell contains chloroplasts? What color is a chloroplast?

Plant cells

Green

What is the name of the green pigment in the chloroplast? Chlorophyll Now I gain control, grab the joystick and manage the nucleus

What is the function of the nucleus?

The nucleus is the brain of the cell

and controls and directs all cell functioning What object, other than a cell, contains a nucleus?

Deciding what comes in there and who should leave –it’s exclusive access The nucleus.

nuclear envelope

The

cell membrane

controls what substances enter and leave the cell.

Genetic glow sticks Provided by the chromatin Define chromatin:

the genetic information in the cell, including DNA and

proteins that form chromosomes which all define the cell’s genetic code The nucleolus brings the ribs What is the function of the nucleolus?

Creates ribosomes, which then produce

protein for support/structure for both plant and animal cells Outside the envelope, waiting in the cytoplasm Define cytoplasm: The cytoplasm is a jelly-like substance that fills the cell, which is mostly made of water. . Inside the cytoplasm there is a protein matrix (created by the ribosomes) to help give the cell its shape. In animal cells, the jelly-like cytoplasm allows for almost total flexibility, in concert with the flexible cell membrane, so that the cell is able to move through small spaces such as blood vesicles. The mitochondria treat you like a meal What is the function of mitochondria? This is commonly referred to as the “power house” of the cell because it is where the energy for the cell is made. The mitochondria generate adenosine triphosphate (ATP) which is the main source of the cell’s energy. What is a meal to a mitochondria? What type of body cells would likely have LOTS of mitochondria? Why? Heart, digestive system

While they try to convert you into something real – tasty What is your favorite food? The longer you stand, waiting in the cytoplasm Lysosomes look at you like you’re bacteria… What is the function of a lysosome? These are digestive organelles that break down and dispose of lots of worn out stuff like bacteria so it does not damage the cell. The Lysosome’s role in the cell is similar to immune and digestive systems in the body…it digests, breaks down, and disposes of potential threats to the body. They’re little round structures filled with chemicals that don’t feel Aiming to break you down The lysosome can be compared to what two human body systems? 1.

Immune

2.

Digestive

Mr. Nucleolus brings the ribosomes that make proteins What is the function of a ribosome? Produce protein for support/structure for both plant and animal cells. Each ribosome makes protein that is distributed around the cell They take an endoplasmic trip around the cell on reticulum 19 What is the function of endoplasmic reticulum (ER)?

The Endoplasmic

Reticulum (ER) is a series of canals that transport materials around the cell The

ribosomes

are often attached to ER. This is called

rough ER.

If

ribosomes

are NOT attached to ER, it is called

smooth

ER.

You know they’re received Cause the golgi bodies put them in these vesicles Where do proteins go after being transported through the ER?

Golgi bodies

What is the function of golgi bodies? The golgi bodies act like the cell’s mailroom  they package proteins into vesicles then they get shipped off to another part of the cell, or different cells, to be used wherever they are needed.

What is a vesicle? Golgi bodies are often called the

Storage unit for cell energy mail

Music Video Extension Activity

1. Hand out or project the lyrics and read them out loud and discuss their meaning 2. Play the song for the students, multiple times, encouraging them to sing along 3. Use the student lyric guide in place of, or to supplement class notes 4. Allow students class time, in small groups, to “act” out a portion of the song 5.
