Cell Structure (Animals) Flashcards
What are the three main structure of the cell?
- Nucleus
- Cell Membrane
- Cytoplasm
Nucleus
Control center of the cell
Cell membrane
Outer boundary of the cell
Cytoplasm
the jelly-like material between the nucleus and cell membrane
There are two categories of cells based on if they have or do not have a ______
Nucleus
eukaryotic cells
Have a nucleus and membrane bound organelles
prokaryotic cells
Do NOT have a nucleus or membrane bound organelles; They DO have DNA and ribosomes
What two things do eukaryotic and prokaryotic cells both have?
DNA and ribosomes
Where is DNA in eukaryotic cells?
Spread through the cytoplasm
What shape is the nucleus?
Spherical
Where is the nucleus located?
Near the center of the cell
Functions of the nucleus
- Controls all metabolic activity
- Plays a role in cell reproduction
Nuclear membrane
Surrounds the nucleus; semi or selectively permeable
Jelly-like material inside the nucleus
Nucleoplasm
Nucleolus
Tiny spherical structure near the center of the nucleus
Chromatin
Elongated DNA in the nucleus
Cytoplasm
a colloid/jelly-like material
What process involves cytoplasm?
Movement
What process involves the nucleus?
Synthesis
What is the structure of the cell or plasma membrane?
An outer and inner layer of phospholipids
Where are the proteins located in the cell membrane?
The lipid bilayer
What do the phospholipids prevent in the cell?
The cytoplasm being dissolved`
What helps with the movement of molecules into and out of the cell?
The lipid bilayer in the cell membrane
What is on the outside of the cell membrane producing energy?
Carbohydrates
