Use www.cellsalive.com to research the following cell organelles. Circle what you are
researching PLANT or ANIMAL cell?
Name of cell organelle
State the function of the organelle and at least 2 facts about the organelle
Nucleus
Function:
communicates with the surrounding cytosol
Facts:
1. The nucleous is the DNA responsible for providing the cell whith a unique
characteristics
2. is the ovious organalle in any eukaryotic cell
Nucleolus
Function:
The Nucleolus produce ribosomes
Facts:
1. The prominent structure in the nucleus is the nucleolus
Cytosol/Cytoplasm
Function:
Control cell metabolism
Facts:
1.
2.
Centrosome
The cytosol is full of proteins that control cell metabolism
Cytoplasm is a collective term for the cystosol plus the organalles suspended
with the cytosol
Function:
an area in the cell where microtubules are produced
Facts:
1. plant and animal cell centrosomes plays similar roles in cell division
2. Both include collections of microtobules
Centriole
Function:
No
Facts:
1. It doesn't have it in the plant cell
2.
Golgi/Golgi Apparatus
Function:
are important in packaging macromolecules for transport elsewhere in the cell
Facts:
1. The Golgi apparatus is a membrane bound structure with a single membrane
2. The stack of larger vesicles is surronded by numerous smaller vesicles containi
those packaged macromolecules
Lysosome
Function:
contain hydrolytic enzymes
Facts:
1. Lysosomes contain hydrolytic enzymes necessary for intracellular digestion
2. Hydrolytic enzymes of plant cells are more often found in the vacuole.
Peroxisome
Function:
break down the hydrogen peroxide into water and oxygen
Facts:
Peroxisome is a membrane bound packets of oxidative enzymes.
Secretory vesicle
Peroxisomes play a variety of roles including converting fatty acids to sugar and assisti
chloroplasts in photorespiration
Function:
Transported to the cell surface for release.
Facts:
1. The secretory example hormones, neurotransmitters
2. are packaged in secretory vesicles at the Golgi apparatus
Cell membrane
Function:
controlled entry and exit of ions like sodium (Na+) potassium (K+), calcium (Ca++
and chloride (Cl-)
Facts:
1. The membrane is made more complex by the presence of numerous proteins
that are crucial to cell activity.
2. These proteins include receptors for odors, tastes and hormones
Mitochondrion/mitochondria Function:
It is on these cristae that food (sugar) is combined with oxygen to produce ATP - th
primary energy source for the cell.
Facts:
1. Mitochondrion membrane bound organelles, and like the nucleus have a dou
membrane
2. Mitochondrian provide the energy a cell needs to move, divide, produce
secretory products, contract
Vacuole
Function:
Water collects in cell vacuoles, pressing outward against the cell wall and producin
rigidity in the plant
Facts:
1.
Vacuola is a membrane bound sac that plays roles in intracellular digestion
and the release of cellular waste products
2. The vacuoleof the plant cell also regulates turgor pressure
Cell wall
Function:
Fluid collects in the plant cell vacuole and pushes out against the cell wall
Facts:
1. Cell wall is made of polysaccharides
2. The cell provides and maintans the shape of the cell
Chloroplast
Function:
The Chloroplast organelles contain the plant cell's chlorophyll responsible for the
plant's green color
Facts:
1. The Chloroplast are specialized organelles found in all higher plant cells
2. Thylakoids appear in stacks called "grana" (singular = granum).
Smooth Endoplasmic Reticulum
Function:
different functions depending on the specific cell type including lipid and st
hormone synthesis, breakdown of lipid-soluble toxins in liver cells, and con
calcium release in muscle cell contraction.
Facts:
1. The Smooth Endo plastic Reticulum is a continuation of the outer nu
membrane and its varied functions
2. membrane bound vesicles and tubules called the endoplasmic reticul
Rough Endoplasmic Reticulum
Function:
electron microscopy due to the presence of numerous ribosomes on its surf
Facts:
1.
2.
Ribosomes
Rough Endoplasmic Reticulum appears "pebbled"
Ribosome collect in the endoplasmic reticulum for transport the cell
Function:
Ribosome where transfer RNA adds individual amino acid
Facts:
1. Ribosomes are packets of RNA
2. Each ribosome comprises two parts, a large subunit and a small subu
Cytoskeleton/microtubules/filamentsFunction:
The internal movement of cell organelles, as well as cell locomotion and m
fiber contraction could not take place without the cytoskeleton
Facts:
1.
The cytoskeleton is an organized network of three primary protein
filaments
2. Cystokeleton helps to maintain cell shape
