Discovery of a Cell

Robert Hooke used a microscope to look at a piece of cork.

He saw little squares that look like prison cells.

Named them cells

Page 3: Unit 7. Discovery of a Cell Robert Hooke used a microscope to look at a piece of cork. He saw little squares that look like prison cells. Named

Organelle

Cells are made of smaller parts called organelles.

Each organelle has a specific function.

Plants and animal cells have some different organelles.

Cell Membrane Covers the outside of the cell and

controls what enters and exits Only animals and plants

Cytoplasm A jelly like liquid that fills the cell.

Organelles can move around the cell Plants and animals

Nucleus Controls all activities in the cell and

houses the DNA. (brain of cell) Plants and animals

Mitochondrion Changes food and oxygen into

energy. (Power house of the cell) Plants and animals

Vacuole Storage area of the cell. Holds water,

food, and minerals……BIGGER in plant cells

Plants and animals

Vacuoles in Plants

Vacuoles are much larger in plants.

Storing food.

Lysosome Breakdown and recycle material in a

cell (known as the “stomach of the cell”)

Animals

Nuclear Membrane

Controls what enters and exits the nucleus.

Cell Wall Surrounds the cell. Gives the cell

shape and structure. (bones of the cell)

Plants only

Chloroplast Contains chlorophyll that traps

sunlight. Photosynthesis occurs here. Plants only

What do you think the green dots are?

Where on a plant would you find cells like this?
