So what is it? What do these all have in common with each other?

Cells… why should I care?

• Building blocks of the plant

• Perform micro functions that leads to the plants livelihood

• Without plants cells… we would starve and have no clothes or shelter!

What is a cell?

• Plant cells are a nucleus and a mass of protoplasm (also known as cytoplasm) contained within a plasma membrane.

• Cells are the basic unit of growth.

What do cells do?

• A group of cells together make up a tissue.

• A group of tissues make up an organ.

• A group of organs make up an organism.

What are the components of a plant cell?

• Nucleus• Protoplasm (Cytoplasm)• Plasma membrane• Cell Wall• Chloroplasts• Vacuole• Plastids • Mitochondrion

What are these components called?

• Cell Organelles

What is the function of the cell wall?

• Rigid• Provides support for

the cell and thus the whole plant

• Provides the cell’s shape

What is the function of the plasma membrane?

• Surrounds the protoplasm

• Allows the exchange of nutrients and gases into and out of the cell

• Semi-permeable

What is the function of the nucleus?

• Brain of the cell• Directs all of the

plant’s life functions• Location of the plant’s

genetic and hereditary make up

What is the function of the protoplasm?

• This is the living matter of the cell

• This is what everything in the cell floats in and maneuvers

What is the function of the chloroplasts?

• Provides green color• Harnesses light

energy, uses water and carbon dioxide to produce glucose and oxygen… AKA photosynthesis

What is a vacuole?

• A vacuole is a storage tank

• This stores waste

What is a plastid?

• Small particle in the protoplasm

• Is a starch or oil or protein

• Gives the plant pigment

• Chromoplast provides red, orange and yellow colors

What is the mitochondrion?

• Converts glucose into usable energy for the plant to perform its many life functions

Is a plant cell that simple?

• There are many other organelles that help to make the whole cell work together and thus allow the plant to perform its life functions.

Make a list of all the organells of a plant cell. From these make an analogy of all the organelles. The organelles need to be part of an entire system.

Example. Cell vs. School Building

Cell Wall = brick outer wall

Plasma Membrane = windows

Choose something that you think a plant can relate to in its make up.

For example, the body, a plane, a car, a bus, type of building

HomeworkWrite a tour of a plant cell. You need to write the cell

tour as though you are a tour guide. For example, “As you will see, we are now pulling up to our destination the plant cell. We will first break through this rigid outer structure. Here are the doors. This is what is known as the cell wall. It provides the nice structure and holds everything in the cell.” You should tour all the organelles we have discussed and walk out the other side of the cell, through the plasma membrane and finally the cell wall.

Include the 8 parts we listed + 2 tissues of your choice.
