What are cells ? |
Cells are the basic units of all living things including animals, plants, and humans.
|
|
|
What do animal cells and plant cells have in common?
|
Both cells have cell membranes, protoplasm (nucleus, and cytoplasm), and vacuoles.
|
|
|
(Animal cell) Cell membrane |
- A thin layer around the cell
- Partially permeable-allowing some substances to pass through, but not others. - The shape of the cell can change |
|
|
(Animal cell) Cytoplasm |
- A jelly-like substance that fills the cell
- Contains (water) and (other substances) - Chemical reactions take place within it |
|
|
(Animal cell) Vacuoles |
- Tiny spaces containing (air, solution or food particles)
- Animals cells have many small vacuoles |
|
|
(Animal cell) Nucleus |
- Controls cell activities
- Contains (chromosomes) which carry (genetic information) |
|
|
(Animal cell) Food storage |
- Store food in the form of (glycogen granules) |
|
|
(Animal cell) Cell arrangement
|
- Not arranged in a fixed pattern
|
|
|
(Plant cell) Cell wall |
- A thick permeable layer surrounding the cell
- Made up of (cellulose) - Supports the cell and gives it a regular shape |
|
|
(Plant cell) Chloroplasts
|
- (Small disc-like structures) found in the cells of green plants
- Contain a green substance called (chlorophyll) which absorbs energy from the sun and uses it to make food |
|
|
(Plant cell) Vacuole |
- A single large space containing (cell sap) which (consists of water and dissolved substances) such as (sugar and mineral salts) - The cell sap keeps the cell turgid or firm by taking in water |
|
|
(Plant cell) Cell membrane |
- A thin partially permeable layer surrounding the cell |
|
|
(Plant cell) Cytoplasm |
- A jelly-like substance that fills the cell |
|
|
(Plant cell) Nucleus |
- Controls the activity of the cell |
|
|
(Plant cell) Cell arrangement |
- Normally arranged in a regular pattern |
|
|
(Plant cell) Food storage
|
- Store food in the form of starch grains
|
