All Cells Have:
Cell membrane
Thin outer layer
Controls what enters and leaves the cell
Found in both plant and animal cells
Cytoplasm
Jelly-like fluid inside the cell
Fills the space and holds all parts
Where many cell activities happen
Nucleus (in most cells, not all)
Found in plant and animal cells
Contains DNA (the instructions)
Controls what the cell does
Mitochondria
Makes energy for the cell
Called the “powerhouse”
Found in plant and animal cells
Ribosomes
Make proteins
Can float in cytoplasm or stick to the rough ER
Found in all living cells
Extra Parts in Plant Cells:
Cell wall
A tough outer layer outside the membrane
Gives shape and protection
Found only in plant cells
Chloroplasts
Make food using sunlight (photosynthesis)
Contain green chlorophyll
Only in plant cells
Large central vacuole
Stores water, nutrients, and waste
Very big in plant cells
Helps keep the cell firm
Other Important Parts (Both Cell Types):
Endoplasmic reticulum (ER)
Moves materials inside the cell
Rough ER has ribosomes; smooth ER does not
Golgi apparatus (or Golgi body)
Packages and sends out proteins
Works like a post office
Small vacuoles (in animal cells)
Store small amounts of materials
Not as big as in plant cells
Note/summary— Plant cells are made of cell membrane, cytoplasm, nucleus, mitochondria and ribosomes, Extra parts in plant cells are cell wall,chloroplast and large central vacuoles, other important parts in both cells are endomplasmic reticulum, Golgi apparatus and small vacuoles.
Why is the cell membrane considered “selectively permeable”?
Why do muscle cells have more mitochondria than skin cells?
If the endoplasmic reticulum is like a factory, what role does the Golgi apparatus play?
What role does the large central vacuole play in plant cells beyond storage?
How do chloroplasts work with mitochondria to supply energy to the plant?
How do plant cells react to losing water and why does the vacuole play a key role in this?
