Organelles and Functions
Cells communicate with each other via chemical signals
How do cells communicate?
Smooth Endoplasmic Reticulum
Location where lipids are synthesized
Cytoskeleton Microfilaments
Make up the cytoskeleton. Protein fibers that help the cell contract and move
Centrioles
Organize microtubules in the cell
Cell Membrane
Outer barrier that regulates what enters and leaves the cell
Chloroplasts
PLANT ONLY - captures light energy from sun and converts it into stored chemical energy through photosynthesis
Cell Wall
PLANT ONLY - provides structure and support for the cell
Rough Endoplasmic Reticulum
builds protein due to attached ribosomes
Mitochondria
converts stored energy into a form the cell can use (ATP)
Vesicles
delivers proteins to end locations
Organs
group of different tissues that work together to perform its function
Organ Systems
group of organs that work together (skeletal system or muscular system)
tissue
group of similar cells that carry out a specific function
Golgi apparatus
sorts and packages proteins for delivery
Cytoskeleton Microtubules
supports cell, provides shape, and used in cell movement
Nucleus
Control Center - has DNA that gives protein making instructions
Cytoplasm
Fluid Portion outside nucleus - gives shape and protection, suspends organelles
Nucleolus
Found inside the nucleus and produces ribosomes
Ribosomes
Site of protein synthesis
True
T/F All cells contain cell membranes
True
T/F Homeostasis occurs in both prokaryotic and eukaryotic cells
False
T/F Prokaryotic cells have a nucles
small organelles filled with enzymes
What are lysosomes?
Cell wall, Cell Membrane
What are the cellular boundary organelles?
tissues, organs, and organ systems
What are the level of organization in multicellular organisms?
store materials like water, salts, proteins, and carbohydrates
What do the vacuoles do?
DNA which includes protein making instructions
What does the Nucleus contain?
Cells must have receptors in order to respond to the chemical signals
What must cells have in order to communicate?
Grow, respond to environment, transform energy, reproduce
What must organisms do to maintain homeostasis?
Ribsomes, Rough ER, Golgi Apparatus, Vesicles
What organelles build proteins?
Chloroplast, Mitochondria
What organelles capture and release energy?
cell wall and chloroplast
What two organelles are only in plant cells?
Plant Cells
What type of cell has a cell wall?
Some receptors can be found in the cellular membrane others are found in the cytoplasm
Where are the receptors located in cells?
Cytoplasm
Where is prokaryotic cell DNA found?
