Eukaryotic (animal) Cells Flashcards
What are eukaryotic cells?
Large complex cells.
What do eukaryotic cells contain?
membrane-bound organelles such as :
a nucleus
mitochondria
endoplasmic reticulum
A)
What is the function of the nucleus?(2)
B)
What are the features of the nucleolus
and nuclear membrane
A)
1-Manages cell organelles
2-Contains the cell’s genetic
information
B)
Nucleolus
* makes ribosomes
* Found inside the nucleus
Nuclear membrane
* Separates the
nucleus from the
rest of the cell.
A)
What is the function of the cytoplasm?(2)
B)
What are the features(1)
A)
1-Allows chemical
reactions
2-Supports
organelles (like
pieces of fruit in
jelly)
B)
1-Jelly-like
2-70-90% water
A)
What is the function of the cytoskeleton?(2)
B)
What are the features(2)
A)
1-Gives strength, support & shape to
the cell
2-Provides movement for objects inside
cell
B)
1-Can be dis- and reassembled to
change the shape of the cell
2- Acts like a monorail system for
transport using “motor proteins.”
A)
What is the function of the Mitochondria?(2)
B)
What are the features(2)
A)
1-the center of the cell
respiration/energy
processing
2- Converts glucose (sugar)
from food to a usable form
of energy called ATP. ATP
is used by cells to do work
B)
* double membranes
* own DNA
A)
What is the function of the Cell Membrane/Plasma membrane?
B)
What are the features(2)
A)
Controls what
enters/exits the cell
B)
* found around outside of
cell
* Selectively permeable:
only allows certain
substances in and out of
cel
A)
What is the function of the Rough ER?
B)
What are the features(3)
A)
*Specialises in making
proteins and transporting
them
B)
*Long membrane
“channels”
*Attached to nuclear
membrane.
*Does have ribosomes
attached
A)
What is the function of the Ribosomes?
B)
Where are they?
What can they be attatched it?
A)
make proteins for the
cell to use
B)
* Some floating free in
the cytoplasm
- Some attached to the
endoplasmic
reticulum
A)
What is the function of the Smooth ER?
B)
What are the features
A)
transport and
communication
* Synthesis of fats &
carbohydrates
B)
* No ribosomes attached
* has tubes and canals.
A)
What is the function of the Golgi Apparatus?
B)
What are the features
A)
* Makes membranes
* creates some products for
secretion
* packages proteins for
storage and/or shipment
B)
* Looks like stacks of
pancakes
* Many layers of membrane
A)
What is the function of the Vesicles?
B)
What are the features
A)
*Carry finished
products to
interior or exterior
of cell.
B)
*Membranes
formed from Golgi
or Cell Membrane
A)
What is the function of the lysosome?
B)
What are the features
A)
*Digest worn out
organelles & foreign
particles
*Destroy bacteria
*Remove toxic wastes
B)
*Contain digestive
enzymes
*About 40 types
A)
What is the function of the Cell wall?
B)
What are the features
A)
* Provides rigid support
and structure to plant
cells
B)
* Found outside the cell
membrane
* Made mostly of
carbohydrates
A)
What is the function of the Large Vacuole ?
B)
What are the features
A)
*Filled with water or ‘sap’
*Supports the plant cells
structure
B)
*Large
